v2.15.0

2.15.0 - 2023-05-31

Added

• dependencies.add_cooldown and dependencies.add_concurrency_limit functions which act as non-decorator equivalents of the relevant "with_" functions.
• AbstractCooldownManager.acquire method which returns an async context manager which acquires and releases a cooldown lock for you.
• AbstractConcurrencyLimiter.acquire method which returns an async context manager which acquires and releases a concurrency lock for you.
• System for using custom cooldown bucket implementations with the standard cooldown manager using InMemoryCooldownManager.set_custom_bucket.
• System for using custom concurrency limiter bucket implementations with the standard concurrency limiter manager using InMemoryConcurrencyLimiter.set_custom_bucket.
• unknown_message option for CooldownPreExecution.__init__ and with_cooldown for setting the response message specifically for the new case of when wait_until is unknown.

Changed

• InMemoryCooldownManager now uses a sliding ratelimit approach rather than fixed window. This also now waits until the command call has finished before starting the countdown for expiring that specific call.
• The datetime passed to with_cooldown's error callback can now also be None when it's unknown.

Deprecated

• AbstractCooldownManager.check_cooldown and AbstractCooldownManager.increment_cooldown in favour of the AbstractCooldownManager.try_acquire and AbstractCooldownManager.release interfaces.
