[Sbcl-announce] SBCL 2.2.9 released

[Christophe Rhodes]

Dear all,

I have just released sbcl-2.2.9; some artifacts have already been
uploaded to SourceForge, though the manual and website pages are still
in the process of being built, and other binaries will become available
in due course. The major changes in this release are summarized below.

Looking forward, we will shortly be in the position that we will no
longer need ASDF to build the contributed modules distributed alongside
SBCL. This means that we now have some options regarding how we should
handle distribution of ASDF. I have set up a poll allowing people to
express their preference of various possible scenarios, or to suggest
their own, at https://forms.gle/4WEvwqjJcu78cqtG9 -- I will read
responses and feed them in to our decision-making; please do give your
opinions.

Best wishes,

Christophe
