## Overview
2+
3+
Thanks again to [Open Source Security, inc](https://opensrcsec.com/) and
4+
[Embecosm](https://www.embecosm.com/) for their ongoing support for this
5+
project.

### Project update
8+
9+
37 pull-requests were merged this month, which makes October one of the
10+
most productive months of this year for `gccrs`. Most of the changes
11+
concerned our name resolution rewrite, and more specifically its
12+
integration to the rest of the compiler pipeline. This paves the way for
13+
the removal of our old name resolution algorithm, which will happen as
14+
soon as all testcases pass using the new algorithm. Some long standing
15+
type system bugs were also fixed, which brings us closer and closer
16+
towards typechecking `core` and being able to compile it. We are now
17+
approaching the end of the Stage 1 period for GCC 15.1, which means we
18+
will soon no longer be able to push changes to common GCC
19+
infrastructure. As such, we are spending some time making sure all of
20+
these changes are properly sent upstream and are being reviewed. Changes
21+
made specifically to the Rust frontend will be upstreamable until the
22+
release of GCC 15.1, in spring of 2025. We are also working towards a
23+
rework of our fork-updating process, in order to make it easier to
24+
develop `gccrs` on the most recent version of GCC. This process is
25+
currently manual, and hard to automate - which is not fair to the
26+
contributor in charge of this task. Spending this time will make it
27+
easier for us to upstream our changes, which will speed up that process.
28+
29+
The technical blogpost from last month was well-received, with positive
30+
comments and conversations on Reddit. It has been linked in the
31+
blog.rust-lang.org blogpost, which has been reviewed and approved, and
32+
should release shortly.
33+
34+
### Community call
35+
36+
We will have our next monthly community call on the 12th of November at
37+
10am UTC. You can subscribe to our calendar to see when the next one
38+
will be held. The call is open to everyone, even if you would just like
39+
to sit-in and listen. You can also subscribe to our
40+
[mailing-list](https://gcc.gnu.org/mailman/listinfo/gcc-rust) or join
41+
our [Zulip chat](https://gcc-rust.zulipchat.com) to be notified of
42+
upcoming events.

## Call for contribution
53+
54+
There are no calls for contribution this month, as we do not have a lot
55+
of good first issues available. Still, feel free to take a look at them
56+
[here](https://github.com/Rust-GCC/gccrs/issues?q=is%3Aopen+is%3Aissue+label%3Agood-first-pr)
57+
and get in touch with us for some mentoring or help!
