mongoDB v2.4.2 released

After the security issue related bumps of the previous releases which happened last weeks it was about time 10gen released a 2.4.x fixing the following issues:

• Fix for upgrading sharded clusters
• TTL assertion on replica set secondaries
• Several V8 memory leak and performance fixes
• High volume connection crash

I guess everything listed above would have affected our cluster at work so I'm glad we've been patient on following-up this release :) See the changelog for details.
