v0.5.0 (13-09-2018)

This release marks the end of the alpha stage of Flexx. Until now, we took the liberty to redesign various parts of Flexx and break the API several times. From now on, we care a lot more about backwards compatibility.

Some highlights of changes from the last release:

  • A major refactoring of the event system.
  • We spun out the PyScript transpiler into the PScript project, as well as the webruntime and dialite project. This means that Flexx itself is focussed on the GUI aspect alone.
  • Added touch support.
  • Dropped the depency on Phosphor.js.
  • A new combined namespace: from flexx import flx.
  • A proper guide in the docs.
  • More examples.

v0.4.2 (13-10-2017)

This release was not published to Pypi. It served mainly as a tag right before the big refactoring. There were a lot of improvements, but we felt that the state of Flexx was still very much in flux (no pun intended).

v0.4.1 (10-07-2016)

A few [fixes](

v0.4 (07-07-2016)

A lot of work and major changes compared to the previous release. Most notably:

  • Completely new event system flexx.event replaces flexx.react.
  • System for configure Flexx through config files, env variables and command line arguments.
  • Better logging.
  • More widgets, more examples.
  • Better notebook support.
  • Fixed nasty bug where new profile data was stored on each launch of the XUL runtime.
  • Better support for testing and running Flexx in a separate thread.

v0.3.1 (19-02-2016)

A few small fixes, and improvements to distribution. The universal wheel on Pypi for v0.3 did not work on Python 2.7. Flexx now includes a recipe to build a noarch conda package.

Also see the overview of 0.3.1 pull request.

v0.3 (15-02-2016)

The most important changes with respect to the previous release are:

  • Flexx now works on Legacy Python (i.e. Python 2.7). The source code is automatically translated during installation.
  • Improvements to nested FlexLayout on Chrome
  • A command-line tool to stop and get info on running Flexx servers.
  • More tests
  • A new Canvas widget.
  • PyScript uses bound functions for methods and functions without selt/this as first arg.

v0.2 (13-10-2015)

We changed a lot, broke API’s, improved things, and probbaly broke other things. Here’s a summary of the most important bits:

  • Set up Travis CI, and added more unit tests.
  • Layout of ui widgets is based on Phosphorjs.
  • Style compliance (and tested on Travis).
  • Refactored PyScript, and made it much more feature complete.
  • PyScript makes use of common ast, and now works on 3.2-3.5, and pypy.
  • We now have a way to include assets (js, css, images).
  • The assets make it possible to e.g. embed a Bokeh plot, or a jQuery widget.
