Really? Subversion 1.4 has been in active development since September
28, when we branched for 1.3. If we branch for Subversion 1.4 in late
February, that means we had 5 months for development.

After branching 1.3, it took 3 months to release the final version of
Subversion. If we branch for 1.4 in February, and Subversion 1.4
follows the same schedule as 1.3, it'll be ready in late May or early
June. That gives us 5 months between releases.

At this rate, new features merged to trunk wait a maximum of 8 months:
- 5 months for feature development
- 3 months for release stabilization
- Total: 8 months

Example: The "wc-replacements" branch was merged to trunk on October
13. If we release Subversion 1.4 in late May, wc-replacements will
have been soaking in trunk for almost 8 months.

Here's another look at the new features, courtesy of Garrett Rooney:

svndiff1 isn't merged to trunk yet, but Daniel Berlin said on December
10 that it's "ready to merge". Should we do the merge now? If it's
ready, let's make sure we merge it before release.
