Official answer: As Pete pointed out, The Apache 2.0 license is not
compatible with the GPL version 2. So that does not meet the current
licensing criterion, which is that the license be compatible with the
GPL version 2.
I'm still deliberating about whether to relax that criterion to allow
GPLv3-only or GPLv3+ (or compatible) code. We're already in the
situation where some plugin directory code is GPLv2-only instead of
GPLv2+, so combining that plugin code with WordPress already requires
If you're writing a plugin, and are able to, I strongly urge to to
license it as "GPLv2 or any later version" (GPLv2+) or just as "GPL,
any version," as that allows for maximum flexibility.
