## When releasing a new version the ACTIVEMQ_LIBRARY_VERSION needs to be updated.
## The following rules apply to the numbers in the version as defined by libtool.
##
##   1. Start with version information of ‘0:0:0’ for each libtool library.
##   2. Update the version information only immediately before a public release of your
##      software. More frequent updates are unnecessary, and only guarantee that the current
##      interface number gets larger faster.
##   3. If the library source code has changed at all since the last update, then increment
##      revision (‘c:r:a’ becomes ‘c:r+1:a’).
##   4. If any interfaces have been added, removed, or changed since the last update, increment
##      current, and set revision to 0.
##   5. If any interfaces have been added since the last public release, then increment age.
##   6. If any interfaces have been removed or changed since the last public release, then set
##      age to 0.
##
## More plainly the follow rules should be used when changing this number.
##
##   1. Programs using the previous version may use the new version as drop-in replacement, and
##      programs using the new version can also work with the previous one. In other words, no
##      recompiling nor relinking is needed. In this case, bump revision only, don't touch current
##      nor age.
##   2. Programs using the previous version may use the new version as drop-in replacement, but
##      programs using the new version may use APIs not present in the previous one. In other words,
##      a program linking against the new version may fail with “unresolved symbols” if linking
##      against the old version at runtime: set revision to 0, bump current and age.
##   3. Programs may need to be changed, recompiled, relinked in order to use the new version. Bump
##      current, set revision and age to 0.
