Announcing the PyCharm 4.5 Release Candidate

We are now approaching the final steps towards the PyCharm 4.5 release which by all means is going to be a milestone for our Python and Web development IDE. So today we’re happy to announce the availability of the PyCharm 4.5 Release Candidate.

Please take it for a spin and give us your feedback. The PyCharm 4.5 RC build 141.1075 is available for download from the Early Access Preview page.

PyCharm 4 Release Candidate includes mostly a consolidation of bug fixes as compared to previous EAP builds. For the detailed list of notable changes and improvements in this build, please check the Release Notes.

Nevertheless, a few new features are introduced in the PyCharm 4.5 RC. First, a couple of new refactorings appeared. With “Convert to Python Package” and “Convert to Python Module” new refactorings you can easily convert a python module to a package and vice versa:


Second, the Python Profile Integration which was introduced in the previous EAP build now works with remote interpreters the same way it does with the local ones. You can easily collect profiler statistics and browse through it with the graph representation:


And last but not least, in the project structure you can now mark a directory as Resource Root for static content such as CSS or JavaScript files, making Django templates, for example, understand the file paths as they should:

In case you missed what’s new in upcoming PyCharm 4.5 – please read the blog posts covering new features in the first, second, and third EAP builds.

You can download the build or upgrade from within the IDE (from previous PyCharm 4.5 EAP builds only) without a full re-installation using the patch-based upgrade. Just make sure you’ve selected the EAP or Beta Releases channel in the update settings.

We hope that there will be no major bugs, however, should you encounter any problems, please report them to YouTrack – we’ll still have a bit of time to fix stuff before the final release.

Stay tuned for a PyCharm 4.5 release announcement, follow us on twitter, and develop with pleasure!

    I have 141.988 EAP installed, but this RC does not show up in PyCharm when checking for updates. Usually it shows up within a few hours. Is a separate download required?

      Hi Steve, sorry for the longer delay this time, it was caused by some technical problems with notifications. Now patch update should work as always.

    I hope there will be an update for the intellij python plugin soon. The current one misses bug fixes for major bugs that were fixed in pycharm 6 weeks ago that makes working with flask/jinja projects unpleasant.
