There are no official release notes of TwinCAT products or change logs. This repository is a community effort which tries to track changes in Beckhoff's TwinCAT software.
There is another unoffcial changelog from Bosch.
If you noticed that a bug was fixed in a certain version or a certain feature was added, please:
- use the edit pencil present on each page at https://cookncode.com/TwinCatChangelog/,
- or add it via a pull request.
- and a link to the source if it is available. If there is no source, mention where you got the information from in the pull request.
In case you have a larger change in mind, please first open an issue such that it can be discussed first. For example, if you want to add a new page, or restructure how the project is organized.
