Early Access Program

PyCharm 2019.1 EAP 4

Our fourth Early Access Program (EAP) version for PyCharm 2019.1 is now available on our website.

New in This Version

Parallel and concurrent testing with pytest


PyCharm makes it easy to run tests quickly using multiprocessing (parallelism) and multithreading (concurrency). All you need to do in order to run your pytest tests in parallel is to install the pytest-xdist plugin as a normal python package using the PyCharm’s package manager, specify pytest as the project testing framework, create a pytest run/debug configuration where you can specify the number of CPUs to run the tests on, and you’re good to go.

Read more about setting up and running pytest tests in parallel in our help

Further Improvements

  • Many JavaScript improvements: PyCharm Professional Edition bundles all JavaScript features from WebStorm. You can read more about the new JavaScript features on the WebStorm blog.
  • Many platform improvements: PyCharm bundles new features and bug fixes coming from the IntelliJ platform
  • And more, read the release notes for details.


Download this EAP from our website. Alternatively, you can use the JetBrains Toolbox App to stay up to date throughout the entire EAP.

With PyCharm 2019.1 we’re moving to a new runtime environment: this EAP build already bundles the brand new JetBrains Runtime Environment (a customized version of JRE 11). Unfortunately, since this build uses the brand-new platform, the patch-update from previous versions is not available this time. Please use the full installation method instead.

If you’re on Ubuntu 16.04 or later, you can use snap to get PyCharm EAP, and stay up to date. You can find the installation instructions on our website.

PyCharm 2019.1 is in development during the EAP phase, therefore not all new features are already available. More features will be added in the coming weeks. As PyCharm 2019.1 is pre-release software, it is not as stable as the release versions. Furthermore, we may decide to change and/or drop certain features as the EAP progresses.

All EAP versions will ship with a built-in EAP license, which means that these versions are free to use for 30 days after the day that they are built. As EAPs are released weekly, you’ll be able to use PyCharm Professional Edition EAP for free for the duration of the EAP program, as long as you upgrade at least once every 30 days.

    MaxJavaStackTraceDepth=-1 outside the allowed range [0 … 1073741823].

    Occured after udpating from the last EAP to this one. I had a project open working without any issues prior to the update. After the update, I restart pycharm and the above pops up.

    Any idea?

    The link in: “And more, read the release notes for details.” doesn’t work

      Thank you for catching this! I’ve fixed the link in the post

    The link for `read the release notes for details` which is `` generates a `Page not found` error.

        It’s still broken, but the one that Scott Palmer posted is correct. I cleared my cache, and the link is still which is wrong.

          Turns out I edited it, but then didn’t save it. Do you happen to know a nice bakery for some good humble pie? I should go eat some.

            February 20, 2019

            Nah, not necessary… we all make mistakes… go out and get some other, yummy, kind of pie!

    The link to release notes is broken.
    is correct I believe.

      You’re absolutely right! Thanks for letting us know!
