[Ftp-release] ANNOUNCE: telepathy-qt4 0.2.1

[Simon McVittie]

The "all you want, only better" release. This is a bugfix release for 0.2.0,
mainly to fix compilation against Qt 4.6.

telepathy-qt4 is a Qt 4 C++ binding for the Telepathy real-time communication
framework, which can be used to implement user interfaces, loggers and
other Telepathy components.

Fixes:

* fd.o #25058: reduce the scope of our workaround for Qt 4.5 bug
  <http://qt.gitorious.org/qt/qt/merge_requests/1657>, fixing compilation
  against Qt versions >= 4.6 beta, where this bug has been fixed (smcv)

* Avoid the installed AccountManager (if any) being service-activated during
  distcheck under some circumstances (smcv)

* Compile with symbols hidden by default, explicitly export a few
  symbols that were mistakenly not exported, and improve the code generation
  tools to be more correct about their exports (smcv)

* Improve the code-generation tools to cope with UTF-8 in the spec (wjt, smcv)

* Enable Automake 1.11 silent building (./configure --enable-silent-rules
  to enable this) (wjt)

Code generation release notes:

* qt4-types-gen.py and qt4-client-gen.py previously forced the generated
  classes to be exported, in a way that's not actually correct for code outside
  telepathy-qt4 (the TELEPATHY_QT4_EXPORT macro).
  
  They now use a macro set by --visibility, defaulting to nothing; if you're
  building a shared library with -fvisibility=hidden, or supporting Windows,
  you may need to use --visibility=YOUR_LIB_EXPORT when running these scripts.

  See TelepathyQt4/global.h or QtDBus/qdbusmacros.h for an example of setting
  up such a macro (unfortunately, the only correct way to do this seems to be
  for each shared library to define its own).

Regards,
    Simon
