v0.3.0 - Sort on List Channel Videos

Added

Sort on the List Channel Videos operation: Latest, Popular (most viewed first), or Oldest. Defaults to unset.

Existing calls are untouched: omitting sort returns the uploads feed exactly as before. sort=latest is a different view (YouTube's Videos tab, Shorts excluded), not a re-ordering of it.

	Feed: Videos, Sort unset	Feed: Videos, any Sort
Source	uploads playlist	channel Videos tab
Page size	~100	~30
playlist_info	populated	null
Shorts	mixed in	excluded (use Feed: Shorts)
Members-only videos	excluded	included, flagged members_only: true

Sort reads ~3.3x more pages (~30/page vs ~100), so it costs ~3.3x credits. Use it when you need ordering; most integrations don't.

Every item now carries members_only. Items from Feed: Streams carry publishedTimeText and lengthText; Feed: Shorts returns null for both.
