Final notes for WordPress 3.5:
1. Expect a release in 10 to 36 hours from now. (The time is currently 0930 UTC. This general window I am providing you is thus is 1900 today to 2100 tomorrow). The release checklist takes up to an hour, which includes letting you know a release is pending, so you will have some lead time while we run through it. (We’ll be in IRC, #wordpress-dev.)
2. The “% selected” string is in core. The translator’s comment: This is a would-be plural string used in the media manager. If there is not a word you can use in your language to avoid issues with the lack of plural support here, turn it into “selected: %d” then translate it. For more see #22749.
3. Two strings, “Insert from URL” and “Set Featured Image”, were added to complete the media modal.
4. Two strings, “Refresh” and “Description”, were moved from the admin to the frontend, which meant a POT file change. (We can probably make this seamless in the future.)
Thanks for your patience this cycle. It has been a very enjoyable one.
