GCC 4.2 was released a few days ago. Here’s the list of changes. Congratulations to everybody who worked on this, and especially to Mark Mitchell for once again doing the release engineering work.

Different parts of GCC evolve at different rates, and due to some quirks of timing, it turns out that the gcj parts of 4.2 are already obsolete. For Fedora we back-ported the 4.3 gcj bits to our base GCC release; I think the other distros are doing the same. Basically what happened is that all our Java 1.5 work came in after 4.2 had closed for major changes.
