Public beta release is coming soon. Progress has been made a little bit over the last few weeks but priorities are lying elsewhere.
Package has been merged. Some further patches are on the mailing list and will be merged soon. After that the package will be re-uploaded to testing again.
Unlikely to be released with Core Update 103.
An update has been posted on the list. Manual user interaction is required to perform the update. Hence it is unknown when to merge this.
Bootstrap is making good progress, but has low priority. Nobody has asked for this in a long time.
