Announcing the PyCharm 4.5.3 RC2

Dmitry Filippov

Having announced the PyCharm 4.5.3 Release Candidate build two weeks ago, today we’ve published the PyCharm 4.5.3 RC2 build 141.1899, which is already available for download and evaluation from the EAP page.

The full list of fixes and improvements for this build can be found in the release notes. The list is really huge so here are the most notable improvements:

  • a couple of important fixes for Python code insight
  • a fix for spurious matplotlib messages in the console
  • a number of fixes for the brand-new Python profiler (including support for Python 2.4 and 2.5)
  • a stunning list of fixes for the integrated Deployment tool.

Download the PyСharm 4.5.3 RC2 build for your platform from the project EAP page and please report any bugs and feature request to our Issue Tracker. It also will be available shortly as a patch update from within the IDE (from 4.5.x builds only) for those who selected the Beta Releases channel in the update settings.

Stay tuned for a PyCharm 4.5.3 release announcement, follow us on twitter, and develop with pleasure!

    PyCharm 4.0.4: Open 1 Django project = 490MB (RAM)
    PyCharm 4.5.2: Open 1 Django project = 750 MB (RAM) (the same project)

    What’s happening, guys? All in one … and … all the things getting too heavy! The memory usage is going to explode.

    Tested: Win 7 SP1 – 64 bits
