StackStorm announces Partnership Program with the 5 founding Partners

by StackStorm Team

Earlier this year StackStorm established a partnership program with some first partners that supported StackStorm in its Open Source journey when the project joined the Linux Foundation.

The Partners Program was created to recognize companies and organizations that provide ongoing assistance to the StackStorm Open Source project. Because of the substantial support provided by these partners, we have been able to expand and improve StackStorm. We would like to officially recognize their efforts and continue to maintain a good working relationship.

Here is the alphabetical list of the founding partners:

StackStorm v3.4.1 – Security fix – CVE-2021-28667

Mar 16, 2021

by Tomaz Muraus and @blag

Today we are announcing StackStorm v3.4.1, a bug fix release which fixes a security issue which has been uncovered recently.

The issue affects anyone who is running StackStorm under Python 3 and doesn’t have a system locale / encoding which is used for StackStorm service processes (st2api, st2actionrunner, etc.) set to UTF-8. Under such conditions, if StackStorm receives a payload with unicode characters which also results in the payload being logged, StackStorm process would go into an infinite-loop trying to decode that payload. This would cause the affected service to have a high CPU utilization and also service log file to grow either until the process is killed or all the available disk space is exhausted (basically result in a DoS).

If you are running StackStorm under Python 3, you are strongly encouraged to upgrade to this release.

For more details, please see the sections below.


StackStorm v3.4.0 Released

Mar 4, 2021

by @blag and Amanda McGuinness of Ammeon Solutions

StackStorm v3.4.0 Release

It has been more than 4 months since our previous v3.3.0 release and we’re super excited about this one!

After Extreme Networks Open-Sourced the EWC Enterprise code last year, this was the most requested and waited release by our Community. In StackStorm v3.4.0 all these goodies have been finally integrated! Besides that, Python 2 Deprecation had happened and many other changes, fixes, and improvements were shipped in v3.4.0.

Let’s get into the details below.


StackStorm project updates: Autumn 2020

Hello Automation folks!
We would like to quickly update StackStorm community about the project progress, releases, plans and roadmap. Here is the overview.


Python 2 Deprecation Plan: Say goodbye to python 2

Nov 16, 2020

By Amanda McGuinness of Ammeon Solutions

Python 2 reached end-of-life on 1st January 2020.  It served us for a long time, but today Python 2 pulls the project down as more packages drop python 2 support, making maintenance hard. Having to keep the codebase py2-compatible means we can’t take advantage of modern Python 3 features.  Removing Python 2 support and relying on Python 3 only is the required thing to do and now it’s finally time!
