Finally all sources have been migrated from SVN to git. I decided to start with a fresh git repository without all the history from SVN. At the moment there are 3 relevant git branches: develop, qwt-6.2 and qwt-multiaxes: see https://sourceforge.net/p/qwt/git/ci/develop/tree/

The SVN repository remains being available if anyone needs code < Qwt 6.2: see https://sourceforge.net/p/qwt/code/HEAD/tree/

Bug fixes

Qwt 6.1.2 is a minor bug fix release, with very few fixes. Its main motivatation is Qt 5.4 compatibility, where QT_STATIC_CONST has been removed.

A first release candidate of Qwt 6.1 is available.

Qwt 6.1 comes with many new features. It supports Qt >= 4.4 ( including Qt 5.0 )

After a maintenance release for Qwt 5.2, this is the update for the Qwt 6.0 branch.

Qwt 6.0.2 is a pure maintenance release collecting all bug fixes that happened since Qwt 6.0.1. It is binary compatible with all other Qwt 6.0 releases.

Qwt 6.0 is not intended to be compatible with Qt 5 - this is what Qwt 6.1 will offer, what is expected to happen soon after Qt 5.0 is available ( about the end of this year ).

Qwt 6.0.0 is major release with substantial API changes because of dropping Qt 3 support.

Its key features are a floating point based render engine for QwtPlot and template classes for implementing new types of plot items.

Qwt 5.2.1 is a maintenance release with a couple bug fixes. It should be binary compatible with Qwt 5.2.0 on most platforms, but I'm not 100% sure about Windows because some pointless declarations for exporting templates have been removed from the headers.

Qwt 5.2.0 is a maintenance release with several bug fixes and a couple of source code incompatible changes.

Maintenance release for Qt 4.5 compatibility. Binary compatible with Qwt 5.1.x.

Qwt 5.1.1 is maintenance release fixing a couple of compiler issues and serious problem with calculating scales, that had been introduced with Qwt 5.1.0.

Qwt 5.1.0 is maintenance release with a couple of incompatible changes and new features. Many of the changes are made for the QwtPolar package.

Qwt 5.0.2 has been released.

Qwt 5.0.2 is a maintenance release with minor changes/fixes.

Key features
------------
1. Redesign of plot items. Makes it much easier to develop individual items.

3. Redesign of the QwtText classes. The MathML renderer of the Qt4 solutions package is embedded. work for all expressions/situations.
4. New classes for navigating: QwtPanner, QwtMaginfier
