I don't know the dates. I could ask, but even then, I'm not sure I can disclose future release dates.
I don't watch for these releases, so when you see one, let us know. Hopefully others will someday learn how to run the utility that creates the checksums so they can update the checksum database. Otherwise you have to wait for me to see the email and do the update. You are welcome to get the sources and run the utility yourself and provide a patch or updated database file so other committers can respond more quickly. If you are interested, ask on the dev@ list.
