HTCondorWiki: Releasing Class Ads

Punchlist for creating a new ClassAds release

Ensure src/classad/CHANGELOG has all relevant changes. Add a section for the new version if necessary.
Update the version number and release date in the follow files:
- src/classad/CHANGELOG
- src/classad/Imakefile: DIST_VERSION
- src/classad/README: first line
- src/classad/new_classad.cpp: ClassAdLibraryVersion() Update both functions with this name!
Update the shared library version number in src/classad/Makefile.am.m4. Look for these two lines:
```
libclassad_la_LDFLAGS = -version-info 1:0:0
libclassad_ns_la_LDFLAGS = -version-info 1:0:0
```
If the ABI has changed, you should increment the first number and set the second and third ones to zero. If the ABI hasn't changed, then increment the second or third number. See http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html#AEN135 for examples of things that will change the ABI.

Ensure the release builds successfully

cd classads-1.0.8
./configure
make
make check
cd ..

Tag the release:

git tag classads_1_0_8
git push origin classads_1_0_8

Copy the release tarball into /p/condor/public/ftp/classad/c++/.
Copy src/classad/CHANGELOG to /p/condor/public/html/classad/c++changelogs/changes-<version>.txt.
Update /p/condor/public/html/classad/classad.html to mention the new release.
