Interday learning cards are now counted in the learning count again,
and are no longer subject to the daily review limit.
The thinking behind the original change was that interday learning cards
are scheduled more like reviews, and counting them in the review count
would allow the learning count to focus on intraday learning - the red
number reflecting the fact that they are the most fragile memories. And
counting them together made it practical to apply the review limit
to both at once.
Since the release, there have been a number of users expecting to see
interday learning cards included in the learning count (the latest being
https://forums.ankiweb.net/t/feedback-and-a-feature-adjustment-request-for-2-1-45/12308),
and a good argument can be made for that too - they are, after all, listed
in the learning steps, and do tend to be harder than reviews. Short of
introducing another count to keep track of interday and intraday learning
separately, moving back to the old behaviour seems like the best move.
This also means it is not really practical to apply the review limit to
interday learning cards anymore, as the limit would be split between two
different numbers, and how much each number is capped would depend on
the order cards are introduced. The scheduler could figure this out, but
the deck list code does not know card order, and would need significant
changes to be able to produce numbers that matched the scheduler. And
even if we ignore implementation complexities, I think it would be more
difficult for users to reason about - the influence of the review limit
on new cards is confusing enough as it is.
The v3 scheduler will delay the final card from being shown twice in
a row, but the overdue case was being treated the same as the no-learning
case, leading to the message being hidden.
Previously we would just use 250% ease for any new card that had no
pre-configured ease, but this will result in decks that have
non-standard ease values to have "set due date" cards in them that don't
match. In order to make this somewhat more efficient, we cache
deckid->ease lookups during this operation.

Unfortunately a popular note taking tool has been misusing cloze
markers in its deck exports. We may want to add this back in the
future, but we'll probably want to start by warning users, to give
people time to adjust.
