This version collects all enhancements from Andrey Skvortsov, Sergey Surkov, Paul Beltyukov, and Alexander Shaykhrazeev over 2016 :
Other enhancements from 2014 and 2015 include :
A lot of IDE and runtime bugs have been fixed since 1.1RC5. See beremiz hg log for details.
MatIEC compiler also got many fixes. See matiec hg log for details.
Beremiz now has a Youtube channel !
New lxml based internal data model representation. Many queries initially performed in pure Python have been replaced by Xpath and XSLT stylesheets, tremendously accelerating operations, specially with large programs. XSLT stylesheets writing was made easy thanks to YSLT, an incredibly powerful Y Language for XSLT.
This was latest Release Candidate. Final 1.1 hasn't been published.
More fixes and optimizations.
Fixes, cleanup and code refactoring.
Half a year after RC1, RC2 comes with many bug fixes, but also new features.
Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards.
It relies on open standards to be independent of the targeted device, and let you turn any processor into a PLC. Beremiz includes tools to create HMI, and to connect your PLC programs to existing supervisions, databases, or fieldbuses.
With Beremiz, you conform to standards, avoid vendor lock, and contribute to the better future of Automation.
Despite of open standards such as IEC 61131, PLCOpen and CanOpen, control engineers cannot deploy results of their engineering effort in an heterogeneous environment. It is usually required to rewrite your PLC program for each particular PLC brand.
The reason for this is that proprietary solutions providers do not fully conform to standards, thus preventing interoperability, harmful to their business model.
Furthermore, standards specification are necessarily non exhaustive and leave some "manufacturer specific" freedom to the implementer. Solution providers make great benefits out of those manufacturer specific details, at the expense of the freedom of the end user.
The Beremiz Project fills the gap between those independent standards specifications, by providing an integrated reference implementation of them.

Some tips for people who never used IRC before:
Ask question and keep running your IRC client until you get answer. If you don't want to keep running your IRC for at least 24 hours, just ask your question on community mailing list.
Official Beremiz bugtracker is https://bitbucket.org/skvorl/beremiz/issues.
If you've found (reproducable) bug, and want it to be fixed. First search bugtracker, maybe someone already reported this issue. If the issue is already described, you may add your examples or comments to it.
If the problem isn't described yet, then please check whether it exists in the latest version of Beremiz from development repository. If it still exists, then create new bug report for it.
Perfect bug report contains:
Bugs in matiec should be reported here.
The easiest way for newcomers to help Beremiz project without python knowledge is to improve support of your native language in Beremiz IDE.
Beremiz developers use Transifex, web-platform for translations. https://www.transifex.com/beremiz/beremiz-ide. It is easy to use and is used by many other open source projects: dpkg, Mercurial, Bitbucket, Fedora, XFCE, PulseAudio, Django and many others. If your language is missing, request it on Transifex. It'll be added ASAP.
Current status of translation.
Beremiz community wiki is here. You are welcome to add/update information there.
Another way to help the project is to improve current state of documentation. For example, you can improve description of functional blocks stored in plcopen/Standard_Functional_Blocks.xml and Additional_Function_Blocks.xml.

The best way to submit your code to Beremiz is to make pull request on bitbucket to this repo.
Before making a pull request please check your code. It should be comform to PEP-8. Commits have to be reasonably small and solve one particular problem each. Commit messages should contain description of the problem that is solved by this change.
For matiec please send patches to email@example.com. This is Beremiz discussion mailing list. For posting it's required to be subscribed to the list.
To make it easier to find your patches, please add '[PATCH][MATIEC]' to e-mail subject.
