And where do I (reliably) look for this kind of information? I find myself googling for 'wordpress changelog' on every other update...
Background: usually I use a "skeletal" WP installation (seperate wp
/app
and wp-content
folders), so I could try out the new major version and check for theme incompatibilites by "hotswapping" the wp
folder. And I'm worried that "swapping back" might not work due to ana migrated DB. Yes I know, I should always back it up before an update anyway. Question still stands :)
