This week in FreeCAD development:

• We merged the **@realthunder **PR that adds a transparency to the sidebars. There is still some work to do with the themes to smooth things out, but the basic feature is present now.

• @paddle reports: “I’m making good progress on assembly solving. I connected to OndselSolver correctly and managed to solve for the first time some fixed joints. Some quirks remaining and more work to be done, but we’re getting there.”

• @yorik switched our primary branch’s name from master to main, in keeping with the current standard for new primary branches.

• I (@chennes) got the new Base64-handling code merged, and am now writing tests for the toponaming-related functions being added to the PropertyTopoShape class.
