Hi sage-devel and sage-release,
here is as official an announcement as we will likely get. Note a
huge amount of work on the sagenb, of course, and also the rather
perplexing issue of what to do with contributions to the sagenb
package, since they aren't merged in any particular alpha. At the
very least be sure to mark a milestone on each and every closed
ticket! Have fun.

Overall weighted coverage score: 79.3%
Total number of functions: 22617
In 4.2, we increased coverage by 0.2%, while adding 145 functions:
Overall weighted coverage score: 79.5%
Total number of functions: 22762
* Known issues
