The meson + port is not fully complete yet, as there are some missing things in the doc + generation and test steps, but for system integration or development + purposes, the port should be fully operational. This major release, including + all its stable updates in the 1.18.x series, will be the last ones providing + support for GNU autotools. The next major release will likely be a meson-only + one, and will therefore not be based on a source release tarball any more, + but on specific git tags instead. + +The most important features and changes in this release are the following: + + * Data session multiplexing can now be enabled in QMI and MBIM modems, e.g. so + that multiple different APNs can be connected separately over a single + network interface. The multiplexing is disabled by default in this release, + except for cases where it's required (e.g. if non-multiplexed sessions aren't + supported) like IPA based Qualcomm SoCs. Users can request the multiplexing + support explicitly via settings when creating the connection bearer object. + + In order to allow easy testing of the multiplexing feature without requiring + any additional change in the stack, a new '--test-multiplex-requested' option + in the daemon allows to switch the default (when not explicitly given by the + user) to attempt to use multiplexing. + + It is worth noting that when multiplexing is enabled, the data network + interface used by the modem will be a virtual network interface created in + runtime, and will therefore have a different name than the real network + interface exposed by the modem. If there are additional settings in the + system relying on the data network interface name (e.g. iptables rules), they + may need to be updated. + + * The ModemManager daemon can run now in a 'quick suspend/resume' mode, in + which no explicit data disconnection is triggered on suspend, and no explicit + device re-probing from scratch is launched on resume. Instead, the daemon + will try to refresh the state of all interfaces upon suspend, e.g. to see if + the module keeps registered to the same operator, to see if it is still + connected, and so on. + + This mode of operation is useful when the WWAN module stays awake while the + host is suspended, and can be enabled with the '--test-quick-suspend-resume' + option in the daemon. + + * API: + ** New '3gppProfileManager' interface, providing operations on the list of + connection profiles stored in the 3GPP module. This interface is + implemented for all AT, QMI and MBIM protocols. + ** New 'DisableFacilityLock()' method in the 3GPP interface, implemented for + QMI and MBIM devices. + ** The 'MaxBearers' property is now deprecated, as it didn't provide any + additional information to what 'MaxActiveBearers' already provides. + ** New 'MaxActiveMultiplexedBearers' property, listing how many bearers can + be connected at the same time if multiplexing is enabled. + ** New settings in the bearer properties, applicable to both the + 'Simple.Connect()' and 'Modem.CreateBearer()' methods: + *** 'multiplex': which allows the user to specify whether multiplexing + should be avoided ('none'), whether it should be mandatory + ('required') or whether it should be enabled if available or skipped + if unavailable ('requested'). + *** 'profile-id': which allows the user to request a connection attempt + with an existing profile stored in the module. + *** 'apn-type': which allows the user to specify the purpose of a given + connection, e.g. the user could create a connection to an APN + providing default internet connectivity and another one to an APN + providing access to the MMS gateway. This setting may or may not be + stored in the module itself, it depends on the type of module. + ** New 'Multiplexed' boolean property in the Bearer object, specifying + whether the bearer is connected through a multiplexed interface. + ** New 'ConnectionError' property in the bearer object, specifying the last + error reported by the module during a failed connection attempt or during + a network-initiated disconnection. + ** Updated the list of enum values in the MMMobileEquipmentError' type, + according to the error codes defined in v17.1.0 of 3GPP TS 27.007. + + * Core: + ** iconv() features support is detected at runtime, and logged when the + daemon starts. + ** Updated the base modem object to allow plugins to specify the types of + data ports they support, based on the specific plugin implementations, + e.g. so that a modem supporting only AT+PPP can ignore NET ports and + vice versa. + ** Added support for modems exposing control ports via QRTR channels. + + * Modem interface: + ** The Dual SIM logic that would iterate over all slots during initialization + is updated, so that we only report the information that we can gather + without any explicit slot change. E.g. with QMI we can know whether there + is a SIM in the non-active slot, and the ICCID of that SIM, but we cannot + know the MCCMNC or the operator name of the SIM unless we change to that + slot. We must not do slot changes arbitrarily like that, and so that logic + is removed, even if we lose some of the information that we were providing + in the interface. + + * Location interface: + ** The multi-sentence NMEA trace support is updated to include additional + possible trace types in addition to GSV (e.g. ALM, GSV, RTE, SFI) and also + when coming from other constellations, not just GPS. + + * SIM: + ** New 'PreferredNetworks' property and 'SetPreferredNetworks' method, + implemented using '+CPOL' for generic AT modems and 'NAS Get/Set Preferred + Networks' for QMI modems. Several different modules and plugins (e.g. + Sierra Wireless EM7345, Telit LN930, SIM7070, all Option and Iridium + devices...) have this feature explicitly disabled due to '+CPOL' not + behaving properly (even crashing the module sometimes). + + * QMI: + ** The logic that decides which data mode (802.3 or raw-ip) is used in + modules managed by the qmi_wwan driver changes in this release. Until now, + if a module reported itself as configured in 802.3 mode on boot, that mode + would be the one used in normal operation. Due to the new multiplexing + feature, this is no longer true, and if possible the daemon will always + try to switch the module to raw-ip, and fallback to 802.3 only if raw-ip + is unsupported. + ** Enabled both AT and QMI indications for the messaging and voice interfaces + so that new SMS and call events are reported via both channels. This + solves issues seen in the Pinephone when waking up from suspend. + ** Enabled network reject indications. + ** If operator name not updated through standard indications, it will be + explicitly queried with 'NAS Get Plmn Name'. + ** Added support for transfer-route MT messages. + ** Increased the QMI open timeout to 45s, as required by the newest modules. + ** Implemented additional logic to read the status of the different facility + locks in the module. + ** Updated ICCID reading logic to parse it as hex instead of BCD. + ** Improved handling of the MNC PCS digit in the operations involving MCCMNC. + ** Automatically run the 'DPM Open Port' logic on IPA based setups to bind + the hardware tx/rx endpoints with the logical ones in the QMI protocol. + ** Implemented support for the Voice interface and its operations, not only + standard voice call management, but also support for the supplementary + services. Voice call management will be done completely using QMI, even + if the new call indications are notified via AT URCs. + + * MBIM: + ** Implemented support for Dual SIM in non-QMI MBIM devices, using the + Microsoft Basic Connect Extensions service. + ** Increased the timeout for the MBIM_CID_HOME_PROVIDER query to 30s. + ** Updated to load model string using QMI over MBIM if available. + ** Increased the MBIM open timeout to 45s, as required by the newest modules. + + * SMS: + ** Defined a common timeout of 180s for all send operations. + + * libmm-glib: + ** Updated with new methods and types to handle all the DBus API updates. + ** Extended with additional methods in the Location3gpp object to get/set the + full operator MCCMNC string, instead of integers without MNC PCS digit + info. + ** Extended the 'ModemLocation' interface with methods to get the signaled + location updates; i.e. without requiring an explicit GetLocation(), and + obviously only supported when location signaling is explicitly enabled. + ** Updated the way the internal monitored properties are handled in the + different types, now using some handy helper macros to share the same + logic among all. + + * Plugins: + ** zte: disabled CIND/CMER support. + ** qcom-soc: added support for QRTR+IPA based setups. + ** qcom-soc: added support for the WWAN subsystem instead of RPMSG. + ** quectel: enabled QGPSXTRA by default when starting the GNSS engine. + ** quectel: add support for EM120/160 PCIe modules. + ** quectel: added Firehose update method. + ** ublox: added additional URAT combinations. + ** ublox: flagged UBANDSEL as unsupported in the SARA-R4 and -N4 modules. + ** cinterion: added new custom MBIM based modem with shared reset operation. + ** cinterion: ignored the MBIM Intel Firmware Update service completely. + ** foxconn: added custom carrier config setup for the T77W968 module. + +The following features which were backported to 1.16.x releases are also present +in ModemManager 1.18.0: + + * core: added support for the new 'WWAN' subsystem in Linux kernel 5.13, + enabling PCIe-only modules. + * core: The charset conversion methods rework, including the avoiding of the + iconv() //TRANSLIT extension support, which isn't available in all libc + implementations. + * qmi: the logic managing allowed/preferred modes was fixed for multimode + devices like the MC7304, making sure the acquisition order preference always + had the same items. + * serial: when modem is connected with AT+PPP, ignore forced disconnections, so + that we don't take ownership of the PPP port before pppd has released it. + * foxconn: added support for the T99W175 (SDX55) module, including built-in FCC + unlock procedure. + * foxconn: added new MBIM QDU firmware update method. + + +ModemManager 1.16.0 +------------------------------------------- +This is a new stable release of ModemManager. + +The following notes are directed to package maintainers: + + * This version now requires: + ** libqmi >= 1.28.0 (for the optional QMI support) + + * The 1.16.x branch will be the last one supporting the 'LEGACY' and 'PARANOID' + filter modes; standard distributions are advised to use the default 'STRICT' + mode if they aren't using it already (i.e. running the daemon without any + explicit '--filter-policy' option). + + * A new 'qcom-soc' plugin is implemented to be able to use ModemManager in + Qualcomm SoCs like the MSM8916 or MSM8974. This plugin uses a combination of + RPMSG based control ports plus BAM-DMUX based network ports. This plugin is + disabled by default, even when `--enable-all-plugins` is used, and if wanted + it must be explicitly enabled with `--enable-plugin-qcom-soc`. Systems + targeting this kind of SoCs, like postmarketos, should enable it. Standard + distributions may or may not include it, up to the targeted hardware in each + distribution. + + * Gentoo's 'libelogind' library may now be used to detect the systemd + suspend/resume support. + +The API is backwards compatible with the previous releases, the only updates +are the following: + + * Modem interface: + ** Updated the 'Ports' property so that it exposes all ports that are + owned by the modem even if they are explicitly ignored and not used. + ** New 'SimSlots' property that exposes the available SIM slots in the modem, + including the SIM object paths in each of them if the cards are present. + ** New 'PrimarySimSlot' property indicating which of the slots in the + 'SimSlots' array is the one currently active. + ** New 'SetPrimarySimSlot' method to select which SIM slot in the 'SimSlots' + array should be considered active. When the switch happens, the modem will + be fully re-probed. + + * Signal interface: + ** New 'Nr5g' dictionary property including signal information for the 5GNR + access technology. + + * SIM interface: + ** New 'Active' boolean property, indicating whether the SIM object is the + currently active one. + ** New 'Eid' string property, indicating the EID of the card, if any. + + * New udev tags: + ** New 'ID_MM_PORT_TYPE_QMI' tag to explicitly flag a port as being QMI, when + there is no other way to guess the type of port; e.g. this tag is not + needed for ports exposed by the qmi_wwan driver. + ** New 'ID_MM_PORT_TYPE_MBIM' tag to explicitly flag a port as being MBIM, + when there is no other way to guess the type of port; e.g. this tag is not + needed for ports exposed by the cdc_mbim driver. + +The most important features and changes in this release are the following: + + * Implemented support for Multi SIM Single Standby support, for systems that + have multiple SIM slots and they can select which of them (only one) is + active at any given time. Currently implemented for QMI modems only. + + * If the modem enabling phase fails in a fatal way, an implicit disabling + sequence is now run, in order to avoid leaving the modem in an inconsistent + state. + + * If the connection attempt includes user/password information but no explicit + authentication type, CHAP will now be used by default instead of PAP. + + * Full USB device removal events reported via udev are no longer used. The + device removal logic relies exclusively on independent port removal events, + as that logic is supported for all subsystems and kernel device backends + (e.g. also working for non-USB devices and for systems without udev like + OpenWRT). + + * Added support to monitor the 'rpmsg' subsystem, but only in plugins that + explicitly require its use (e.g. the 'qcom-soc' plugin). + + * New options in the ModemManager daemon: + ** Added new '--test-no-suspend-resume' option to disable the runtime + suspend/resume support even if the daemon was built with it. + ** Added new '--test-no-udev' option to disable the runtime udev support even + if the daemon was built with it. + + * Serial: + ** Also match OK or ERROR responses that are not at end of line. + + * SIM: + ** Force reprobing the modem if a new SIM is detected in a modem that + initially started in Failed state without SIM. + ** Force reprobing the modem if the lock status cannot be read after sending + SIM-PUK, so that it transitions to the Failed state. + ** Force reprobing the modem if a PUK lock is discovered after sending + SIM-PIN, so that it transitions to the Failed state. + + * QMI: + ** The logic no longer depends on the service version reported by each + client, the support for each feature is explicitly probed instead. + ** Implemented SIM profile (eUICC) change detection. + ** Support for QMI modems on kernels < 3.6 is dropped. Only kernels where the + QMI control ports are exposed in the 'usbmisc' subsystem are supported. + ** Implemented additional step in the connection logic to allow binding the + WDS client to a given SIO port, required in the BAM-DMUX driver setup. + ** Implemented support for the initial EPS bearer settings logic. + ** Disabled explicit signal and access technology polling if indications have + been correctly enabled. + + * MBIM: + ** Enable SIM hot swap detection logic with QMI over MBIM. + ** Allow plugins to specify explicitly that QMI over MBIM is not supported. + + * libmm-glib: + ** Added missing APIs to get/set RM protocol in the Simple connect settings. + + * Plugins: + ** gosuncn: new plugin, for now just with port type hints for the GM800. + ** quectel: implemented GPS support with +QGPS. + ** quectel: implemented custom time support check to prefer +CTZU=3 instead + of +CTZU=1 so that the modem reports localtime instead of UTC in +CCLK. + ** sierra: added support for XMM-specific features (e.g. EM7345). + ** cinterion: implemented support for the initial EPS bearer settings logic. + ** cinterion: added SIM hot swap support to AT-based modems. + ** huawei: updated to avoid applying multiple port type hint methods. + ** huawei: updated the ^GETPORTMODE logic so that we don't assume the hints + in the response apply to specific USB interfaces. + +The following features which were backported to 1.14.x releases are also present +in ModemManager 1.16.0: + + * location: allow CID only updates. + * sms: allow sending/receiving UTF-16 as if it were UCS-2. + * modem: don't consider charset setup failure as fatal. + * QMI: fix reporting signal strength indications. + * QMI: fix parsing of USSD indications with UTF-16 data. + * QMI: run network registration with NAS Set System Selection Preference. + * QMI: when connection aborted, ensure network handles are released. + * MBIM: don't fail IPv4v6 connection attempt if only IPv4 succeeds. + * cinterion: improve user/password handling in AT^SGAUTH calls. + * cinterion: removed limitation to IPv4 only PDP contexts. + * cinterion: configure the PLAS9 to send URCs correctly. + * quectel: add support for MBIM devices. + * telit: add initial delay for AT ports to become responsive. + * udev: updated all AT/QCDM/GPS port type hints in all plugins to bind them to + TTY ports only. + + +ModemManager 1.14.0 +------------------------------------------- +This is a new stable release of ModemManager. + +The following notes are directed to package maintainers: + + * This version requires: + ** GLib/GObject/GIO >= 2.48.0 + ** libmbim >= 1.24.0 (for the optional MBIM support) + ** libqmi >= 1.26.0 (for the optional QMI support) + + * Build updated with several improvements: + ** The build has been updated to use by default all warnings enabled by + AX_COMPILER_FLAGS(), and therefore when building the release from a git + checkout, autoconf-archive >= 2017.03.21 is now required. This new build + dependency isn't required when building from the release tarball. + ** Also when building from a git checkout, beware because by default + --enable-compile-warnings=error is enabled, which implies -Werror. If + you'd like to build from git and avoid -Werror, you should explicitly use + --enable-compile-warnings=yes (to keep the warnings but without being + errors), --enable-compile-warnings=no (to disable all the extra warnings + enabled by default) or --disable-Werror (to unconditionally make all + compiler warnings non-fatal). + ** Users can now preselect which plugins to build and install during + configure, with the --enable-plugin-[PLUGIN-NAME] options. The user can + also build and install all except for some, just by using the + --enable-all-plugins option followed by --disable-plugin-[PLUGIN-NAME]. + By default all plugins are enabled, so all of them built and installed. + This new set of options are useful for users building custom systems + where they already know what kind of devices they're going to have, it + isn't recommended for standard distributions. + +The only updates in the public API are the following: + + * Modem interface: + ** Added support for AT-based and/or QMI-based 5G devices, which will report + the new MM_MODEM_CAPABILITY_5GNR capability. + ** Deprecated the MM_MODEM_CAPABILITY_LTE_ADVANCED capability, as it was + never used in any implementation. + + * Bearer interface: + ** Added additional 'attempts', 'failed-attempts', 'total-rx-bytes', + 'total-tx-bytes' and 'total-duration' values in the 'Stats' property + exposed by the Bearer objects. + +The most important features and changes in this release are the following: + + * The daemon switched to 'STRICT' filter mode by default. The old 'DEFAULT' + mode is renamed to 'LEGACY' and is considered now deprecated. Under the + 'STRICT' filter mode, the TTY blacklist and greylist are ignored, and the + port probing mechanism uses its own heuristics to guess whether a given TTY + is owned by a modem or not. + + * Added a new implicit whitelist rules applicable in 'STRICT' filter mode, so + that all devices with a USB vid matching one of the vids allowed by the + different installed plugins are implicitly allowed. + + * Updated daemon logging so that we always prefix the messages with a string + identifying which modem the log refers to, making it easy to grep logs for + one specific device if the system has more than one. + + * Updated the probing logic to make sure we don't attempt a re-probe when the + device is gone. + + * Probing logic now allows new ports detected up to 1500ms since last port + added, useful on OpenWrt setups where ports are notified one by one via + hotplug events. + + * AT: + ** Moved the charset definition logic to the initialization phase instead of + the enabling phase, because the feature support checks may already require + string processing based on the current charset. + ** Updated manual registration operation to attempt using current charset + (e.g. UCS2) if ASCII fails. + + * QMI: + ** Devices using the LOC service for GNSS will now also setup the list of + required NMEA traces before starting the engine. + ** Implemented 3GPP USSD support using the Voice service. + ** Update carrier code if registration changes from one roaming operator to + another. + ** Explicitly disable autoconnect during modem enabling phase, because it + interferes with our connection management logic. + ** Fallback to raw-ip if WDA Get Data Format requests arguments, as in most + new 5G devices. + ** Updated to always use the asynchronous close() operation. + ** Handle disconnection indications during connection attempts. + + * MBIM: + ** Update carrier code if registration changes from one roaming operator to + another. + ** Implement reset in Intel-based and Qualcomm-based devices. + ** Avoid LTE attach config/status if unsupported. + ** Updated to make sure all allocated QMI CIDs are released during shutdown. + + * SIM interface: + ** Don't allow sending PIN/PUK if not required. + + * 3GPP interface: + ** Fixed manual re-registration to the same operator. + + * CDMA interface: + ** Don't allow multiple concurrent activation attempts. + ** Disallow empty carrier code in automatic activation. + + * Bearer interface: + ** Updated to avoid connection checks or stats updates while disconnecting. + + * libmm-glib: + ** New 'mm_location_gps_nmea_get_traces()' method to retrieve a NULL + terminated array of strings with all cached NMEA traces. + ** Deprecated the 'mm_location_gps_nmea_build_full()' method. + + * mmcli: + ** Added a new 'any' lookup keyword for the --modem and --sim options, useful + when the system is only expected to have one single device. + + * Plugins: + ** broadmobi: new plugin, right now just with port type hints for the BM818. + ** foxconn: new plugin to support the T77W968 (both with and without eSIM). + ** dell,dw5821e: added support for the DW5821e with eSIM variant. + ** huawei: don't delay reporting network initiated disconnects. + ** huawei: try to read port type hints from interface descriptions. + ** huawei: avoid using the QCDM port during a voice call. + ** cinterion: skip sim ready check for modules that don't support it. + ** cinterion: implemented radio/band handling for LTE modems. + ** cinterion: added Signal interface support bsaed on AT^SMONI. + ** cinterion: added support for MBIM based devices like the PLS62-W. + ** quectel: updated to detect SIM hot swap via +QUSIM URCs. + ** fibocom: added support for QMI based devices like the FM150. + ** ublox: ignore error when disconnecting last LTE bearer. + ** ublox: implement support to enable and detect +UUDTMF URCs. + ** ublox: added blacklist rules for GPS modules in the plugin itself. + ** sierra: implement manual and automatic CDMA activation. + ** novatel: implement manual and automatic CDMA activation. + +All the features and fixes which were backported to 1.12.x releases are also +present in ModemManager 1.14.0. + + +ModemManager 1.12.0 +------------------------------------------- +This is a new stable release of ModemManager. + +The following notes are directed to package maintainers: + + * This version requires: + ** libmbim >= 1.18.0 (for the optional MBIM support) + ** libqmi >= 1.24.0 (for the optional QMI support) + + * The build allows to configure with '--with-at-command-via-dbus' in order to + unconditionally enable the Modem.Command() method to allow running AT + commands through ModemManager. This is not suggested for standard + distributions, though. + +The most important features and changes in this release are the following: + + * Modem interface: + ** Updated logic to avoid assuming that setting bands or modes is immediate, + the daemon will now actively monitor for those updates to happen before + returning success. + + * 3GPP interface: + ** libmm-glib: deprecated the mm_pco_list_free() helper method. + + * Simple interface: + ** api,libmm-glib: deprecated the 'subscription state' property. + + * Location interface: + ** Fixed 'unknown' lat/long/alt numeric values. + ** Added support for MSB A-GPS in addition to MSA A-GPS. + + * Voice interface: + ** Improved voice call management with call id detection and tracking. + ** Improved detailed call state transitions on generic modems that support + call list polling. + ** Added support for GSM supplementary services, including call waiting, + call transfer, call deflection, multiparty calls... + ** Added emergency call support, allowing voice call to emergency numbers + even without SIM or with SIM-PIN locked. + ** Deprecated all properties except for 'number' in the CreateCall() + method. + + * Messaging interface: + ** Updated to report SMS timestamps in correct ISO8601 format. + + * Bearer: + ** Improved unused CID lookup to allow selecting non-sequential CIDs. + ** Disabled all AT protocol based context monitoring when PPP is used for + the connection, in order to properly sync with pppd, which should be the + one detecting the disconnections (already in 1.10.6). + + * QMI: + ** Improved support to list stored firmware images in Sierra devices. + ** Added additional lock check retries on 'SIM not inserted' errors. + ** Updated explicit registration attempt to report success only when the + target requested network is registered. + ** Added MSB A-GPS support. + ** Implemented automatic carrier configuration selection using PDC service + (already in 1.10.2). + + * mmcli: + ** New machine-readable JSON output with '--output-json'. + ** Updated to allow using the modem UID to specify SIM operations. + + * udev: + ** New ID_MM_PORT_TYPE_AUDIO generic udev tag to identify ports that + should be used for in-band audio. + ** Removed support for the ID_MM_PLATFORM_DRIVER_PROBE udev tag, as it + is no longer required given that the more generic explicit whitelist + may be used to flag which devices should be probed. + ** Renamed ID_MM_DEVICE_MANUAL_SCAN_ONLY to ID_MM_TTY_MANUAL_SCAN_ONLY, + given that the tag only applies to TTYs. + ** ID_MM_DEVICE_IGNORE is no longer used internally in ModemManager, and + is instead targeted to users that want to explicitly ignore specific + devices regardless of what filter type is in use (already in 1.10.6). + + * dbus: + ** Updated to always report the registered MM_CORE_ERROR_CANCELLED error + instead of the implicit G_IO_ERROR_CANCELLED ones generated by GLib. + + * GObject introspection: + ** Fixed setup to explicitly skip all non-API methods. + + * Plugins: + ** tplink: new plugin. + ** dlink: new plugin. + ** xmm: added MSB A-GPS support. + ** dell,dw5821e: update to allow unmanaged GPS support on the TTY even + when raw/NMEA GPS is enabled via QMI/LOC. + ** quectel: updated to allow TTY-only devices. + ** telit: added GPS support. + ** telit: improved band management with #BND. + ** simtech: added improved voice call support. + ** simtech: added support for LTE devices. + ** simtech: improved signal quality reporting logic. + ** simtech: added GPS support for the SIM7000/SIM7600 family. + ** cinterion: added support for time updates. + ** cinterion: added improved voice call support. + ** ublox: added improved voice call support. + ** ublox: improved band management with UBANDSEL. + +All the features and fixes which were backported to 1.10.x releases are also +present in ModemManager 1.12.0. + + +ModemManager 1.10.0 +------------------------------------------- +This is a new stable release of ModemManager. + +The following notes are directed to package maintainers: + + * This version requires: + ** libmbim >= 1.18.0 (for the optional MBIM support) + ** libqmi >= 1.22.0 (for the optional QMI support) + +The most important features and changes in this release are the following: + + * udev: + ** Consolidated common tag names among all the supported plugins. E.g. + ID_MM_PORT_TYPE_GPS, ID_MM_PORT_TYPE_AT_*, ID_MM_PORT_TYPE_QCDM... + All these generic tags are included as symbols in the API, and + compatibility will be maintained for these. Custom setups of + ModemManager relying on previously available per-plugin udev tags may + need to manually port them to this new generic subset. + ** New tag to allow specifying flow control settings to use in serial ports. + + * Core: + ** Avoid probing other protocols on TTYs tagged in udev with specific port + type tags (e.g. avoid probing QCDM if a port is tagged as AT). This allows + faster port probing and modem detection for known modem layouts. + ** Implemented support to enable and handle +CGEV URCs for asynchronous + connection state updates in AT-controlled devices. + + * Manager interface: + ** New runtime daemon version reporting. + ** New support for requesting device inhibition, e.g. so that ModemManager + stops completely using a modem device until the inhibition is released. + This feature is implemented to allow fwupd taking over of a device + completely for as long as it needs during a firmware update. + + * Modem interface: + ** All methods are always connected, even in Failed state. + ** Allow parallel Enable()/Disable() calls. + ** Deprecated redundant ListBearers() method, the read-only Bearers property + is already showing the same information. + + * Bearer interface: + ** New 'BearerType' property, e.g. to specify whether a bearer is the initial + LTE default bearer or not. + ** Deprecated 'number' field in bearer settings. Applications do not need to + send the 'number' field in Bearer.Connect() or in Modem.Simple.Connect(), + as the setting is totally ignored. + + * mmcli: + ** New 'key-value' output, easier to parse by scripts than the default. + ** Removed redundant '--location-get-XXX' actions, as the '--location-get' + already reports the location information for all sources. + ** Removed redundant '--simple-status' action, as the same information can be + obtained through different mmcli operations. + ** New manager '--inhibit-device' action and modem-specific '--inhibit', to + allow requesting device inhibition. + + * 3GPP interface: + ** New support for exposing the network reported Protocol Configuration + Options (PCO), to be used instead of the new deprecated Subscription + State property. + ** New support for exposing the initial LTE default bearer status. + ** New support for configuring the initial LTE default bearer settings. + + * Location interface: + ** New LTE Tracking Area Code (TAC) in 3GPP location information. + ** New support for injecting assistance data (e.g. Qualcomm XTRA) into the + GNSS engine, useful when there is no mobile connection to use MSA A-GPS. + + * Firmware interface: + ** Support for reporting firmware update support properties, e.g. specifying + which update methods are supported. This information will be consumed by + fwupd in order to allow upgrading firmware in devices managed by + ModemManager. + + * Voice interface: + ** Multiple improvements and fixes in the voice call management logic + implemented with generic AT commands. + ** Added AudioPort and AudioFormat properties to the Call object. + ** Added new generic audio channel setup/cleanup handlers in the Call object. + + * QMI: + ** New LOC service based GNSS support, including A-GPS setup via SUPL server. + ** New support for the "extended" LTE band list. + ** New support for reading IMSI and ICCID with the UIM service. + + * MBIM: + ** Implemented support for processing Protocol Configuration Options using + Microsoft-defined Basic Connect Extensions. + ** Implemented support for LTE attach status and configuration using + Microsoft-defined Basic Connect Extensions. + ** Implemented support for the extended signal interface and for 3GPP location + details using the AT&T specific service. + ** Implemented support for 3GPP USSD operations using the standard USSD + service. + ** For Qualcomm-based MBIM devices, those with QMI-over-MBIM support, a whole + new set of features is now available, including: QMI LOC/PDS location + support, allowed/preferred mode management, frequency band selection, + power management operations... + + * Plugins: + ** xmm: new XMM plugin, with shared logic (allowed/preferred mode management, + frequency band selection, power management operations, extended signal + quality reporting, GPS/A-GPS...) for Intel XMM based devices. + ** fibocom: new plugin, with support for generic MBIM and XMM-based devices. + ** dell: added support for XMM-based devices, like the DW5820e. + ** dell: added custom support for the DW5821e, including 'unmanaged' GPS and + firmware update integration details. + ** cinterion: new shared interface to include all logic shared between Option + and Option/HSO devices. + ** sierra-legacy: implemented connection monitoring support. + ** u-blox: added support for extended call state transitions. + ** u-blox: added CDC-ECM support for SARA/LISA-U2xx modems. + ** altair-lte: migrated from SubscriptionState to PCO. + +All the features and fixes which were backported to 1.8.x releases are also present +in ModemManager 1.10.0. + + +ModemManager 1.8.0 +------------------------------------------- +This is a new stable release of ModemManager. + +The following notes are directed to package maintainers: + + * This version requires: + ** GLib 2.36.0 + ** gettext 0.19.8 (for the optional rebuild of documentation) + ** libmbim >= 1.16.0 (for the optional MBIM support) + ** libqmi >= 1.20.0 (for the optional QMI support) + ** libsystemd >= 209 or libsystemd-login >= 183 (for the optional suspend + and resume support) + ** libsystemd >= 209 (for the optional systemd journal support) + ** polkit >= 0.97 (for the optional PolicyKit support) + + * This version no longer requires: + ** intltool (replaced by new features in gettext) + + * Distributions using systemd should explicitly use the following configure + options: + ** '--with-systemd-suspend-resume': the only supported source for suspend and + resume events is now systemd, so the previous '--with-suspend-resume=[]' + option was renamed. + ** '--with-systemd-journal' to use the new journal support. + + * Distributions wanting to avoid ModemManager poking TTY ports that isn't + supposed to touch may start using the new 'STRICT' filter policy, given + as an option to the ModemManager daemon (e.g. patching the default systemd + service file provided). See below for more info about the filter policy and + the side effects of using the STRICT approach: + ** E.g. ModemManager --filter-policy=STRICT + +The most important features and changes in this release are the following: + + * New 'filter policy' setting in the ModemManager daemon to decide which ports + are probed and how. Currently these levels are defined: + ** WHITELIST-ONLY: Only devices or ports explicitly whitelisted with the new + 'ID_MM_DEVICE_PROCESS' udev tag are probed. + ** DEFAULT: All ports are allowed to be probed except for the ones explicitly + greylisted as RS232 adapters or completely blacklisted. This is the + default approach that was used until now, and the default as well in this + release if a different one isn't requested. + ** STRICT: The daemon defines a set of heuristics to try to detect modems and + ports to probe. Only the TTY ports that are very very likely to be modem + ports are probed, therefore completely avoiding the need of having a + separate blacklist or RS232 adapter greylist. But note that this policy + may end up ignoring some devices, like TTY controlled modems without an + associated network port. + ** PARANOID: This is equivalent to running the STRICT mode but also applying + the blacklist and RS232 greylist filters explicitly. + + * Device 'naming'. This release includes logic to allow 'naming' devices with + the ID_MM_PHYSDEV_UID udev tag, so that the names can then be used in e.g. + mmcli and also exposed in the 'Device' property in the Modem interface. This + new setup makes it possible to give the devices unique names that are kept + across reboots. + + * Allow skipping the automatic scan for devices in the daemon with the new + '--no-auto-scan' daemon option. Instead, the daemon may be called with the + '--initial-kernel-events=[PATH]' option including a predefined list of ports + or otherwise get the port additions reported during runtime with the + mmcli --report-kernel-event=[] command. + + * Allow building and running without 'udev'. In this setup, the previously + explained '--no-auto-scan' is enabled by default, so ports are not + automatically detected .Note that this setup is not suggested for standard + distributions: if udev is available in the system, it is the preferred method + to manage the port addition and removal. + + * SIM hot swap. The core includes the needed logic to support SIM hot swap in + the different devices, although for now it's only tested for Telit and MBIM + modems. If a SIM hot swap is detected, the modem is flagged as failed and + reprobed from scratch. + + * Connection status monitoring logic. In order to try to detect network + initiated disconnections, a generic setup is provided to plugins so that they + can implement explicit connection status checks that would be executed + periodically. + + * New support for 3GPP CSFB states and operation modes. We now support + registration states reported as "SMS only" or "CSFB not preferred", and + provide APIs to set and get the "UE mode of operation for EPS". + +This version comes with the following new features: + + * Build and system: + ** Updated the systemd service file with additional security related rules. + ** Added support for systemd journal logging. + ** Updated most of the code to use GTask instead of the deprecated + GSimpleAsyncResult based operations. + ** ChangeLog is built from git during the dist tarball generation. + + * New translations: Polish, Brazilian Portuguese, Slovak, Hungarian, Czech, + Ukrainian, Swedish and Indonesian. + + * API: + ** Defined additional GSM, UMTS and LTE frequency bands. + ** The MMModemBand enumeration values (EUTRAN, UTRAN and CDMA) have been + renamed to consolidate how they are defined. A compatibility layer has + been provided to avoid breaking the API. + ** New 'HardwareRevision' property in the Modem interface. + ** New 'EpsUeModeOperation' property and 'SetEpsUeModeOperation' method in + the Modem 3GPP interface. + + * Core: + ** Updated libqcdm to load signal strength from QCDM EVDO Pilot Sets. + ** Updated udev rules with new per-vendor rules for quicker processing. + ** Explicitly ignored ports are never probed now, but they will be reported + as owned by the device and exposed in the Ports property. + ** New 'ID_MM_TTY_BAUDRATE' udev tag to specify the baudrate to use in RS232 + TTY ports. + ** If using UCS2, still assume that the operator name may be given in ASCII. + ** Explicitly open QCDM ports anytime it's needed, instead of assuming they + are open when enabled. + ** Query supported ME event reporting options and automatically set the best + choice based on the supported ones. + ** Query supported flow control modems and automatically set the best choice + based on the supported ones. + ** Explicitly configure flow control settings on the TTY as soon as it is + connected, only applicable for RS232 devices. + ** Implemented generic unlock retries loading. + + * MBIM: + ** Explicitly reprobe the modem when the mbim-proxy is detected dead. + ** Workaround implemented to keep track of the PIN1 unlock retries as the + protocol isn't very good allowing this. + ** Load and expose HW revision. + + * QMI: + ** Explicitly reprobe the modem when the qmi-proxy is detected dead. + ** Load and expose HW revision. + ** Detect port closed and forbid client allocation operations. + ** New optional connection status monitoring support, enabled by default for + the Netgear AC341U. + + * Location interface: + ** Disabled by default for MBIM modems. + + * Messaging interface: + ** Try decoding with UTF-16BE when UCS-2 reported. + + * Plugins: + ** u-blox: new plugin, currently supporting the TOBY-L2, TOBY-L4, TOBY-R2, + LARA-R2 and LISA-R2. + ** quectel: new plugin, supporting generic AT/QMI based modems. + ** cinterion: implemented support for devices exposing a WWAN network + interface. + ** cinterion: support changing modes in LTE capable devices. + ** cinterion: added GPS support for devices controlled only with AT^SGPSC. + ** cinterion: use ^SIND unsolicited messages for access tech reporting. + ** huawei: implemented Signal interface. + ** telit: added support for RS232, QMI and MBIM modems. + ** novatel: cleaned up registration state and access tech reporting. + ** novatel-lte: implemented unlock retries loading. + ** dell: speed probing time up and reduce udev dependency. + ** mbm: added GPS support for the Dell DW5560. + +The following features which were backported to 1.6.x releases are also present +in ModemManager 1.8.0: + + * Build and System: + ** Explicitly use -DGLIB_VERSION_MIN_REQUIRED=GLIB_VERSION_2_36 and + -DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_36 so that we don't get warnings + for GLib features that are flagged as deprecated in newer versions. + ** Dropped After=syslog.target rule in systemd service file. + ** Added all ModemManager udev tags also in "bind" events. + + * Core: + ** Improved detection of 4G-only modems. + ** TTY is set as connected as soon as ATD replies. + ** Removed the default ID_MM_PLATFORM_DRIVER_PROBE whitelist. + + * Signal interface: + ** Report RSCP if available. + ** New generic implementation of the Signal interface in AT-based devices + using AT+CESQ. + + * QMI: + ** Run FCC auth sequence if "InvalidTransition" is reported when going + online. + ** Added WDS reporting event support. + + * Plugins: + ** huawei: let the E3372 run NDISDUP via TTY (when the exposed cdc-wdm is + non-functional). + ** telit: added support for the GE910. + +ModemManager 1.6.0 +------------------------------------------- +This is a new stable release of ModemManager. + + * This version requires: + ** GLib 2.36.0 + ** gettext 0.19.3 + ** libmbim >= 1.14.0 (for the optional MBIM support) + ** libqmi >= 1.16.0 (for the optional QMI support) + ** libsystemd >= 209 or libsystemd-login >= 183 (for the optional suspend + and resume support) + + * For distributions using systemd, it is suggested that the new optional + suspend/resume is explicitly requested during configure with the new + '--with-suspend-resume=systemd' argument. + +This version comes with the following new features: + + * Core: + ** Implemented support for suspend/resume detection, currently working + when systemd is in use.
