Version 0.5 released

This is mostly technical release - now windows version is build against Qt 4.8,
minizip is updated up to 1.1 and zlib updates issues fixed.

The encryption support using QCA is added. Now questions can be encrypted
using mentat-crypt utility and all GUI tools can work with encrypted files. Due to
law restrictions, feature is off by default and will not be present in builds. You will
have to build mentat by yourself with encryption enabled and provide QCA and
SSL libraries.

The intent for encryption is to hide data stored locally from examined persons,
to prevent cheating.

Qt 4.7.x is broken for Mentat

It looks like mentat is hit by Qt-bug 18050 (, thus Checkbook(and probably other apps) segfaults on course preparation. I've just tested Qt 4.8 and it works OK.

Mentat v.0.4a is released

Checkbook UI is redesigned to provide better user experience.
Long operations now show progress bars. Now new courses can
be easily installed using checkbook from zip archives. Simple
sport quiz course (in russian) is available to download from the
'Files' section. And a lot of small fixes here and there, as usually.
This release also brings some initial versions of ExamClient and ExamServer - not yet functional, but providing a good base for further
development. Also some protocol documentation is included.

mentat v.0.3a is released

This release brings almost all checkbook features implemented in quick'n'dirty style. Now it is possible to actually use checkbook to learn some course and estimate your knowledge. Expression engine is polished and works well. New types of questions were added: multiple choice and regular expression. Windows version now uses antialiased fonts.

A lot of ittle annoying bugs were fixed and much more were added =). Memory leaks are known to present in checkbook and related code, database operations are blocking GUI and WebViews are rendered multiple times, so expect some slowness; this will be fixed in next releases.

mentat v.0.2a is released

Back to active development after a summer break!

Major changes are:
1) Data locations are now standard system directories (user/system-wide)
2) Windows installer does all dirty work
3) Windows binaries are now made using cross-compiler rather than
building on windows
4) Clenaup in makefiles regarding build/installation tools
5) New programs in suite: ConfigInfo and Setup to view what and where installed.

Known bugs:
- Qt Webkit is working very strange on windows - almost freezes app on start, when ready javascript/css seem broken.
- Checkbook is not working properly on windows - segfaults on opening

Problems will be addressed in 0.2b and 0.2c releases.
