Automatic notification of new releases of free 32-bit version?

Is there a mechanism by which we can be notified of new releases of the free 32-bit version of kdb+?  So far I just sporadically re-download and run it and see if the version has been incremented.  But it would be handy if there was a better way.

Also, is there a set of release notes somewhere?  I’m curious about what changes from version to version (bugfixes, refinements, feature additions, feature deletions).

no, currently these are one of the perks of licensing the 64bit version.
