If you want to be always up to date about what's cooking for the next #phosh release (besides what's already merged to the main branch) check out phosh-next: https://source.puri.sm/Librem5/phosh-next - it gets all the merge-requests that are waiting for more review, some minor cleanups, etc. The current list of MRs is in the commit message and `debian/changelog`.
Please don't ship that in distributions but additional review, feedback and testing is certainly very welcome.
@chrichri no pbuilder involved for l5-fetc-hnext.
That's just a bunch of things `librem5-dev-tools` pulls in to ease development. We can move them to recommends.
The script really just downloads things and installs them via `dpkg -i`. Note that for #phosh you also need phoc-next libwlroots10 from octarine.
This has been live since July but I think I never "formally" announced it.
