I do understand this and remember the timing issue well. I also do
understand why the 1.30 release was not changed at the last moment to
accomodate Update 4, as it would have delayed 1.30 well beyond the date in
which it was planned to be released.

I agree with those people.

Yes, that would be valuable from library implementors. I have also pushed in
the past for library implementors to be more responsive to documenting
changes from Boost release to release of their libraries, but this idea has
been ignored as a whole although a few library developers actually do this.

My main concern is that code which tests specifically for some BCB6
__BORLANDC__ number, such as 0x561, and assumes only this means BCB6, has
not been updated to also test for 0x562 and 0x564 when appropriate. But I
don't know if this is the case anywhere, which was the reason for my
original post.
