0.7.0

Allow Pecorino.adapter to be assigned, and add adapter: to all classes. This allows the adapter for Pecorino to be configured manually and overridden in an initializer.
Add Redis-based adapter derived from Prorate
Formalize and test the adapter API
Add a memory-based adapter for single-process applications (and as a reference)
For SQLite tables, do not use UUID primary keys - there is no need for that, and SQLite does not have a antive UUID gen functin that is enabled on all builds

0.6.0

Add Pecorino::Block for setting blocks directly. These are available both to Throttle with the same key and on their own. This can be used to set arbitrary blocks without having to configure a Throttle first.

Add CachedThrottle for caching the throttle blocks. This allows protection to the database when the throttle is in a blocked state.
Add Throttle#throttled for silencing alerts
BREAKING CHANGE Remove Throttle::State#retry_after, because there is no reasonable value for that member if the throttle is not in the "blocked" state
Allow accessing Throttle::State from the Throttled exception so that the blocked throttle state can be cached downstream (in Rails cache, for example)
Make Throttle#request! return the new state if there was no exception raised

Use Bucket#connditional_fillup inside Throttle and throttle only when the capacity would be exceeded, as opposed to throttling when capacity has already been exceeded. This allows for finer-grained throttles such as "at most once in", where filling "exactly to capacity" is a requirement. It also provides for more accurate and easier to understand throttling in general.
Make sure Bucket#able_to_accept? allows the bucket to be filled to capacity, not only to below capacity
Improve YARD documentation
Allow "conditional fillup" - only add tokens to the leaky bucket if the bucket has enough space.
Fix over_time leading to incorrect leak_rate. The divider/divisor were swapped, leading to the inverse leak rate getting computed.

Allow over_time in addition to leak_rate, which is a more intuitive parameter to tweak
Set default block_for to the time it takes the bucket to leak out completely instead of 30 seconds
