Digia has announced the release of the beta version of Qt 5.2:

Of interest to Stellarium:
- the new QTimeZone class:
http://doc-snapshot.qt-project.org/qt5-stable/qtimezone.html
(please **don't** do anything stupid with it without me)

- the QKeySequenceEdit class:
http://doc-snapshot.qt-project.org/qt5-stable/qkeysequenceedit.html

- Android is now an officially supported platform

From here: http://qt-project.org/wiki/New-Features-in-Qt-5.2
- "Added support for embedded clear button commonly used for item view filtering and side actions to QLineEdit" :)
- "Added placeholderText property to QTextEdit"
- and a number of other stuff that may be useful.

Of course, this is still a beta, so...

Unfortunately, Digia continues the practice of making only an OpenGL build for MinGW. (The MSVC builds also get a version that supports ANGLE, i.e. they can use DirectX instead of OpenGL on Windows, which would solve my problems...) I think I've managed to get an ANGLE-enabled build from a third party ( http://sourceforge.net/projects/mingwbuilds/ ), but I haven't tested it yet.
