notefeed 0.27.0: post a note with an earlier date

notefeed 0.27.0 is out.

• You can now post a note with a time in the past instead of now, from a date and time with its offset or just a date, back to 1970. The note then sits at that time in the feed, its read link and RSS.
• The compose box has a date-and-time field next to Tags for this. From scripts, send the X-Note-Created header. The JS client takes createdAt and notefeed post --created, the Python client takes created_at and --created, and AI assistants can pass created_at to post_note.
• If something polls a feed for notes newer than the last one it saw, it will miss notes posted with an earlier date.
• The footer and the ⓘ menu now link to notefeed's own release notes and this blog.

All the details are in the release notes and on GitHub.
