8.1.5 release note

От

As usual, following item in the 8.1.5 release note is pretty vague:
    * Efficiency improvements in hash tables and bitmap index scans(Tom)

Especially I'm wondering what was actually improved in bitmap index
scans. I see several commit messages regarding bitmap index scans, but
I cannot figure out which one is related to the item.

Any idea?

Sorry for the delay. I don't know the answer.  The commit messages are
the only way.
