[lime] lime-app in the next release

Hi!
I have a few questions about testing the release candidate.
If I have understood correctly, the version of lime-app going into the release will be a newer one than the current release 0.2.25 from March 2022. So would it make sense to test libremesh with the version of lime-app that goes into the release? In the last meeting the question was raised where the development of lime-app is currently happening. Are there any news about this? The github repo of lime-app stops at May 2023 and has switched to preactjs since the last release. Should I use its develop branch for testing?
Another question: Should I use the the 2023.1 or the master branch of lime-packages for testing?
