Details about new 3.4.12 release

[Shawn Heisey]

In this issue on Solr, it came (indirectly) to my attention that ZK 
3.4.11 is no longer available for download:

https://issues.apache.org/jira/browse/SOLR-12277
There is no info available about 3.4.12 yet on the ZK website, and since 
the download for 3.4.12 doesn't seem to include any kind of changelog, I 
can't figure out what exactly is wrong with 3.4.11 to result in it 
disappearing.

Are there changes coming soon to the ZK page to explain what's happening?

Thanks,
Shawn
