As you may know, Canonical is working at the Ubuntu Touch OTA-6 Update, which has recently reached feature freeze.
Recently, Łukasz Zemczak has announced that before the feature freeze, Unity 8 has been updated, new Messaging app, Network Manager and PulseAudio versions have been implemented.
If you don’t know, a system that has reached feature freeze usually does not receive any new features, the developers focusing on squashing bugs and implementing security optimizations.
Until Ubuntu Touch OTA-6 Update gets released, Canonical has to fix the emulator builds.
As a reminder, Ubuntu Touch is a stable operating system, but it is not mature enough, compared to Android and iOS. For now, there are three Ubuntu Phones: Bq Aquaris E5 HD, Bq Aquaris E4.5, Meizu MX4, but the system is also officially supported on the LG Nexus 4 device.
