TS 2.5 SP2 has been released. Bugs fixed:
1) Custom data of some types (such as memo or string) not shown in subtasks view.
2) Unable to create Float custom field without default value.
3) More simple error mesages (without stack trace).
4) sman starts jetty with javaw (instead of java) - no additional console window
How to upgrade:
Just download package and install it. No database upgrade required. You can copy all *.properties from old (2.5 and 2.5SP1) distribution.
