Hi All,
Here is my current draft of the LLVM 2.1 release announcement.
Unlike previous announcements, I'm not planning to largely duplicate
the release notes in the announcement.
In addition to this, I've checked in the first draft of the release
notes into llvm/docs/ReleaseNotes.html (http://llvm.org/docs/
ReleaseNotes.html).
I'd really appreciate it if anyone who contributed to LLVM 2.1 could
review the release notes and clean up the description of their (or
others') contributions. The ordering in the release notes isn't
final, and feel free to add items that I've overlooked!

Project Notes:
--------------
The LLVM 2.1 has many improvements, including three new front-ends,
huge reduction in -O3 compile times, a new (beta) MIPS backend, and
many optimizer/code generator changes that allow LLVM to produce
better code. In addition to new features, LLVM 2.1 includes a large
number of bug fixes found by compiling a huge number of applications,
OS kernels, and very large open source projects.
Organizationally, the LLVM 2.1 cycle is memorable for several
reasons. In this release we switched from CVS to SVN, moved llvm-gcc
to the main LLVM server (it used to be in a private repository which
was mirrored publicly once a day), and grew the community very
rapidly: we added many new commiters. Another interesting metric is
the the main LLVM repository (not counting llvm-gcc or other separate
projects) crossed 500K LOC: http://llvm.org/nightlytest/locgraph.php?
xsize=900&ysize=600 .
One of the highlights of this release cycle was the ability for many
of us to get together to meet face to face at the 2007 LLVM Developer
Meeting: http://llvm.org/devmtg/2007-05/ . If you're interested,
many great talks about LLVM are available on that page, including a
great section where everyone introduces themselves to the world :).
In the end, the most exciting thing about the LLVM project is seeing
all the ways that people apply the technology and having happy
users. If you're currently using LLVM for nifty things or are
writing papers, please let us know. There are a bunch of nice new
publications available (see http://llvm.org/pubs/ ), but I am certain
that we're missing some. If you're using LLVM please let us know -
*particularly* if there is something you don't like about it. :)
Instead of a including a listing of the major features in this
announcement as I normally do, I'll point you to the LLVM 2.1 release
notes [ http://llvm.org/docs/ReleaseNotes.html#whatsnew ] which
includes the high-level items.
This release wouldn't be possible without many people in the LLVM
community: building new features, reporting bugs, testing the pre-
release
bits, and contributing in many other ways. Tanya (our release manager)
deserves a lot of credit for this being the smoothest and best
release so
far, as well keeping our releases coming out on time!
If you have any questions or comments, please contact the LLVMdev
mailing list (llvmdev at cs.uiuc.edu)!
