[wwwdocs] Update changes.html with libstdc++ changes

[Jonathan Wakely]

[-- Attachment #1: Type: text/plain, Size: 453 bytes --]

This adds recent libstdc++ updates to gcc-5/changes.html

I'm also noting one old change in the GCC 4.5 page, and
removing/changing some links to the C++0x status table. The list of
features supported on trunk is fairly irrelevant to someone looking at
the 4.4 release notes, so I've linked to the docs for the relevant
release, or just removed the link for 4.4 and 4.5 because we don't
have libstdc++ docs online for those releases.

Committed to CVS.

Nice!  Just a most minor change to end a list with a full stop 
instead of a semi-colon.  Applied.

This was a good change, thank you.

The only drawback of this, and some similar cases, is that we now
risk referring to older versions on a release branch.  I do not
have a good idea how to best handle this, so for now I updated
references to online documentation to the latest versions (4.8.4 
and 4.9.2, respectively).

Yes, I realised that problem when making the change and linking to the
versions that were current at the time. One option would be to add a
gcc-4.8 symlink that points to the latest gcc-4.8.x version, but that
adds more work for the release managers and only has a small benefit.

Alternatively, since we only tend to have four or five releases from a
branch, we could just update them manually when we remember to. That's
only necessary until the branch closes, at which point the latest
release won't change. It's not a huge problem if the links don't go
to the latest docs immediately IMHO.

Agreed, and agreed.  Let's just keep an eye on it and (try to)
update when a new release of an existing branch comes out.
