There are many improvements on this version!
The major one is that the PyDev.Debugger got some attention and should now be 60%-100% faster overall -- in all supported Python versions (and that's on top of the improvements done previously).
This improvement was a nice example of trading memory vs speed (the major change done was that the debugger now has 2 new caches, one for saving whether a frame should be skipped or not and another to save whether a given line in a traced frame should be skipped or not, which enables the debugger to make much less checks on those occasions).
Also, other fixes were done in the debugger. Namely:
- the variables are now properly displayed when the interactive console is connected to a debug session;
- it's possible to select the Qt version for which QThreads should be patched for the debugger to work with (in preferences > PyDev > Debug > Qt Threads);
- fixed an issue where a native Qt signal is not callable message was raised when connecting a signal to QThread.started.
- fixed issue displaying variable (Ctrl+Shift+D) when debugging.
Note: from this version onward, the debugger will now only support Python 2.6+ (I believe there should be very few Python 2.5 users -- Python 2.6 itself stopped being supported in 2013, so, I expect this change to affect almost no one -- if someone really needs to use an older version of Python, it's always possible to get an older version of the IDE/debugger too). Also, from now on, supported versions are actually properly tested on the ci (2.6, 2.7 and 3.5 in https://travis-ci.org/fabioz/PyDev.Debugger and 2.7, 3.5 in https://ci.appveyor.com/project/fabioz/pydev-debugger).
The code-completion (Ctrl+Space) and find definition (F3) also had improvements and can now deal with the Python super (so, it's possible to get completions and go to the definition of a method declared in a superclass when using the super construct) and pytest fixtures (so, if you have a pytest fixture, you should now be able to have completions/go to its definition even if you don't add a docstring to the parameter saying its expected type).
Also, this release improved the support in third-party packages, so, coverage, pycodestyle (previously pep8.py) and autopep8 now use the latest version available. Also, PyLint was improved to use the same thread pool used in code-analysis and an issue in the Django shell was fixed when django >= 1.10.
And to finish, the preferences for running unit-tests can now be saved to the project or user settings (i.e.: preferences > PyDev > PyUnit > Save to ...) and an issue was fixed when coloring the matrix multiplication operator (which was wrongly recognized as a decorator).
Thank you very much to all the PyDev supporters and Patrons (http://www.patreon.com/fabioz), who help to keep PyDev moving forward and to JetBrains, which sponsored many of the improvements done in the PyDev.Debugger.
