I tried installing version 2.5.2. A word to the wise: don't.
I have reverted my system to 2.5.1, and everything seems fine except for one teensy problem: the module airtime-liquidsoap appears not to exist. Here's what I'm seeing:
root@server1:/usr/bin# airtime-check-system
PHP Warning: Module 'geoip' already loaded in Unknown on line 0
I ran 'apt-get remove airtime', then 'apt-get purge airtime', and for good measure I went to /usr/bin and made sure airtime-liquidsoap was gone.
I then reran 'apt-get install airtime', and it ran the install, and when it got to the end and ran the system check, the 'airtime-liquidsoap' task had failed to start.
Starting it manually, I got this:
oot@server1:/usr/bin# service airtime-liquidsoap start
* Starting Liquidsoap Playout Engine without Monit process watchdog. To make sure Monit is watching
* Liquidsoap, use 'start-with-monit' instead of 'start'.
