Hey hey,

This is the fourth bugfix release in the 1.18.x series, built from the mm-1-18 branch.

ModemManager 1.18.8

  * A new connection status dispatcher setup is provided, where users can provide custom scripts that will be called on bearer connect/disconnect events. This dispatcher will make the netifd integration in openwrt work much better, as we'll be able to report network-initiated disconnections cleanly to netifd.

    There are no default connection status dispatcher scripts installed, but it's suggested distributions make sure the following directories exist:
      - ${sysconfdir}/ModemManager/connection.d/
      - ${libdir}/ModemManager/connection.d/

  * API:
    ** Add missing Simple interface definitions in ModemManager-names.h.

  * Build:
    ** meson: fix daemon enums dependencies.
    ** meson: fix port enums includes.
    ** meson: fix 'export_packages' in GIR setup.
    ** meson: fix simtech plugin module name.
    ** systemd: don't run ModemManager in containers.

  * Core:
    ** serial: ensure the port object is valid after BUFFER_FULL handling.
    ** netlink: use unaligned netlink attribute length.
    ** netlink: only change IFF_UP flag.
    ** bearer: match unknown auth to chap in loose comparisons.
    ** charsets: return error if UTF-8 validation fails.
    ** fcc-unlock: make scripts POSIX shell compatible.
    ** modem-helpers: consider minimum ID when choosing best profile.
    ** modem-helpers: fix reading <Act> given in COPS=? responses.
    ** sms: prevent crash if date is out of range.
    ** profile-manager: fix copy-paste error on tags for quarks.

  * QMI:
    ** Ignore slot status indications until initial status is known.
    ** Return error when loading capabilities if none is found.

  * MBIM:
    ** Default initial EPS bearer's auth to chap when unknown.
    ** Update default error when network error is out of range.

  * mmcli:
    ** Fix key length when printing list of items.

  * Plugins:
    ** linktop: new port type hints.
    ** cinterion: add support for PLSx3w modems
    ** huawei: disable +CPOL based features in Huawei E226

  * Several other minor improvements and fixes.
