It seems as it was forgotten to add a git tag (I already reported that)
and the relevant changelogs, however the website and my self-hosted
instance notified about the new release.
It makes sense though to update now since this release fixes the
integration of `drawio` into the wiki.
For the sake of completeness, all changes made since `v3.8.0`
can be viewed in https://github.com/documize/community/compare/v3.8.0...30d12ba756101a3d360e874cc8fad2a53ec558ed
TLDR: default.nix was pointing to an unmaintained code base whereas stable.nix is up-to-date and maintained.
History
1. At first their was one Python version of vdirsyncer that had been working fine for years. Then, maintenance decreased and the package was marked as broken in nixpkgs.
2. The original author (@untitaker on github.com) of vdirsyncer decided to re-implement (part of) vdirsyncer in Rust. Nixpkgs made `vdirsyncer` point to the Rust version and renamed the Python historical version to `vdirsyncerStable`.
3. Eventually, @untitaker gave up on the Rust version.
4. Someone else (@WhyNotHugo on github.com) decided to take over maintenance of the Python version.
5. Mario Rodas (@marsam on github) and Damien Cassou updated the `vdirsyncerStable` to point to the work of @WhyNotHugo and mark the package as working again.
We currently build CONFIG_IPV6=m.
This seems to be not really well-supported in mainline kernels - see
https://lore.kernel.org/netdev/20201115224509.2020651-1-flokli@flokli.de/T/#u
Compiling it as a module doesn't give too much benefit - even for people
who did explicitly set `enableIPv6` to false, the `ipv6` module was
still loaded, as soon as another module was loaded that requires it
(bridge,br_netfilter,wireguard,ip6table_mangle,sctp,…).
By compiling it in, we only loose the possibility to not add it to
`boot.kernelModules` anymore (as it's part of the kernel directly). The
space savings are negligible.
People wanting to disable IPv6 still get the appropriate sysctls and
options set (while having the kernel code loaded), nothing is really
changing here.
