All GeSHi releases since 18.104.22.168 onward are compatible API-wise, so
just drop in the newest one from the newer GeSHi releases or the SVN
trunk/release branch (stable version which is labelled 1.0.X).

In regards to GeSHi: No. No new features since 22.214.171.124 IIRC in regards
to the API. So You're missing nothing.

There is software with more bugs and security flaws in it on the server
than GeSHi and the guy at Wikimedia reviewing the code said he couldn't
find flaws at all ;-)
The CVEs I was referring to were:
- One issue with local/remote file inclusion which was in a function
that was never called with user-controllable data (and has been fixed by
me knowing no application uses this function in any way it can become
- One infinite loop that got in there by accident (which was while the
parser was restructured between 126.96.36.199 and 188.8.131.52).
- An XSS from the early days which was with one of the really early
version. Since then the parser has been rewritten at least two times
The infinite loop CVE was my fault when I missed one testcase in one
release, all the others came from the opriginal author, thus they are
history now, since there's not much of the original code left.
Furthermore the point that even many major sites use it in setups with
high security standards (and not only Joe Average's webserver waiting to
be hacked) indicates there is at least some security in there.
And by the way: Being able to give an exact number of CVEs without
having to look up that number clearly speaks for its security. BTW: The
last CVE got created 4 months AFTER 2 releases with the bugfix for the
respective bugs was out. Debian took another 2 months to do the bugfix.
For more details on the Debian issue you might want to read in my blog
Regarding MediaWiki Updating: 1.15 is kinda "recent"; the last Mediawiki
I updated was 1.4 ... The SyntaxHighlighting_GeSHi extension should work
there even without updating it. Just make sure to grab the more recent
files for GeSHi from the GeSHi release as mentioned above.
