That is great news.

The current 'staging' branch is just about ready for merge[*], so a Mesa
update will have to wait until the next round.

However, I think libGL is fairly ABI-stable, so you may be able to
"graft" this version in the mean time, like in commit
fdd883509301845ddb4dc90e70e58b469afb5441.
