GitHub will discontinue Subversion support, which is the basis of all the packages hosted in KLayout (https://github.blog/2023-01-20-sunsetting-subversion-support/). KLayout uses the SVN interface to download the package data.

As a quick mitigation, it is possible to host packages on SourceForge with Subversion selected as the code tool. This will mean manual effort upon releasing GitHub-hosted projects. This used to be very convenient with the subversion bridge.

To facilitate this migration I will add SourceForge to the package repositories and remove GitHub.

Important: Existing packages will be transferred to a read-only KLayout-owned SVN repository so they will continue working.

As a long-term solution, I plan to add Git support for package download. That means:

• It will again be possible to deploy KLayout packages directly from GitHub
• KLayout packages have to reside at the top level of a Git repo (specifically: grain.xml needs to be located at top level). So far, it was possible to use a sub-folder as the package home. This will no longer work. A workaround is to use a Git submodule for the package part.
• This deployment path will only work for new KLayout versions (target is 0.29)
