0.24.3 is now available in the regular locations (uploaded to  
rubyforge, and available http://reductivelabs.com/downloads/puppet).

Here's the changelog:

     Modified the ldap node terminus to also use the facts version
     as the version for a node, which should similarly encourage the
     use of the yaml cache.  (Related to #1130)

     Caching node information in yaml (I figured caching in memory will
     cause ever-larger memory growth), and changing the external node
     terminus to use the version of the facts as their version.  This
     will usually result in the cached node information being used,
     instead of always hitting the external node app during file
     serving. Note that if the facts aren't changed by the client,
     then this will result in the cached node being used, but at this
     point, the client always updates its facts.  (#1130)

     Fixing #1132 -- host names can now have dashes anywhere.
     (Patch by freiheit.)

     Fixing #1118 -- downloading plugins and facts now ignores noop.
     Note that this changes the behaviour a bit -- the resource's
     noop setting always beats the global setting (previously,
     whichever was true would win).

     The change in checksums from 'timestamp' to 'mtime' no longer
     result in updates on every run (#1116).

     Aliases again work in relationships (#1094).

     The CA serial file will no longer ever be owned by
     root (#1041).

     Fixing the rest of #1113: External node commands can specify
     an environment and Puppet will now use it.

     Partially fixing #1113: LDAP nodes now support environments,
     and the schema has been updated accordingly.

     Always duplicating resource defaults in the parser, so that
     stacked metaparameter values do not result in all resources
     that receive a given default also getting those stacked
     values.
