Unfortunately the previous release (1.8.1) was crashing due to a
segmentation fault (didn't have time to investigate), but this release
works fine so far.
Had to switch from GCC 8 to GCC 9 due to the following internal compiler
error:
/nix/store/qsc6w1cnjp4pr7d90bhc0sid01i8k0a0-range-v3-0.5.0/include/range/v3/utility/compressed_pair.hpp:50:92: internal compiler error: in tsubst_pack_expansion, at cp/pt.c:12200
meta::if_<meta::strict_and<std::is_constructible<Ts, Args>...>, int> = 0>

This is a refactoring of "tdesktop", i.e. the resulting derivation isn't
affected by this commit (only the tdesktopPackages.* attributes are
removed).
I decided to remove the attributes "tdesktopPackages.*" as I don't
maintain the preview version anymore. There are regular stable releases
and we depend on the patches from Arch Linux which only track the stable
version as well, i.e. I would have to maintain our own patches, which
would either require an additional repository or "bloat" Nixpkgs (apart
from the fact that it would be unnecessarily time-consuming).
GCC 8.x is required to avoid the following error:
cc1plus: error: -Werror=class-memaccess: no option -Wclass-memaccess
If we build without "-Wno-error=class-memaccess" the build should fail
and the upstream requirements were raised from GCC 7 to GCC 8 anyway:

The two additional patches are required to avoid build errors like this:
/build/source/Telegram/ThirdParty/qtlottie/src/bodymovin/bmbase.cpp:123:12:
error: invalid use of incomplete type 'class QDebug'

TODO: We're still using the old API ID (like the Arch package) which
should be used for testing only.
I've tried to contact the Telegram team multiple times via different
channels but didn't get a response so far. See [0],[1] for more details.

Without the patch the build will fail with the following error:
