D.gnu - GDC release cycle

I was wondering what the schedule for the GDC release is, since 
GDC is quite a bit behind on the dlang frontend version.
Is it a release whenever a couple new major D features appear? A 
new release when there's a bugfix? Or does GDC follow GCC's 
release cycle? Even then, when does new checked-in code make it 
into the actual release?

IIRC, GDC follows GCC's release cycle.

That's what confuses me, according to the GDC project website 
that is linked to at the dlang download page the underlying GCC 
version of GDC is 3 major versions behind GCC.
Should I be worried if I want to use GDC?

As far as I understand it / remember, the DMD frontend version 
that was merged into GCC 9 was based on the last version of the 
DMD that was still written in C++ before it got bootstrapped to D 
(2.068 or something) because GCC 9 needs to be able to be 
compiled with GCC 8 (which doesn't have D).

Now GCC 9 has D, a more modern version of DMD's frontend can be 
merged into GCC 10.
However, there is some trouble because a recent bug-fix (the 
non-global template issue, 5710) made it harder to update the D 
frontend for GDC because it changed the glue code significantly, 
which has to be adapted / reverted for GCC's backend.

See: https://github.com/dlang/dmd/pull/9702#issuecomment-516737748

I haven't heard anything since, so I don't know what's going to 
happen.
Iain Buclaw is the one qualified to talk about this.

I personally just use LDC currently, which closely follows DMD 
releases.
It would be really cool if GCC contains a modern D compiler 
though.

At this rate, the best things to focus on will be getting more ports
and platforms added and feature complete - OSX, MinGW, BSDs on SPARC,
PPC, HPPA, etc...

There are a couple bootstrap problems that have come to light both
from compiling with current dmd master, or when testing for the first
time the jump from first to second stage bootstrap.

I have taken pretty much 4 months off with intermittent brief returns
since Dconf to rebase and test dmd master (those who were present at
Dconf will know why) and my free time will likely only reduce further
from here on out for the next decade or so.

Sad to hear that, but thank you for your work on putting D in GCC.
Is there a donation incentive for it already? If not, you may 
want to talk to Mike Parker about that.

I briefly received intermittent reimbursements for infrastructure
costs for various CI components I have running, that stopped since
Andrei stepped down and his preferred form of payment platform decided
to close up shop.
