Today's update (d75be48) brings with it the following changes:
Security issues
- Operating system of all servers upgraded to Ubuntu 18.04. This was part of a larger process to migrate away from the soon-to-be unsupported Ubuntu 14.04 version.
Bugfixes
- Fixed a race condition in the wav2mp3 request handler that could sometimes cause the playback of voice recordings to not play back on the initial attempt.
