Revision history for ecstasy

0.3.0.0 -- unreleased

Replace 'State s' with 'ReaderT (IORef s) IO', resulting in significantly less allocations.
Perform static analysis of 'QueryT's to avoid evaluating them on irrelevant entities.

0.2.1.0 -- 2018-05-15

Added the 'surgery' function to introduce temporary effects.
Significant performance improvements due to constructing monadic generic functions via 'Codensity'.

0.2.0.1 -- 2018-05-10

Also export 'StorageType'.

0.2.0.0 -- 2018-05-10

Renamed 'get*' to 'query*'.
Renamed 'newEntity' to 'createEntity'.
Renamed 'defEntity' to 'newEntity'.
Renamed 'defEntity'' to 'unchanged'.
Renamed 'defWorld' to 'defStorage'.
Significant performance improvements.
Added a 'Virtual' component type, allowing for easy integration with systems that own their own data. Getting and setting on 'Virtual' components dispatch as actions in the underlying monad stack.
Added proper type wrappers around 'SystemT' and 'QueryT' so they don't eat up valuable mtl instances.
Removed the 'Ent' parameter from the 'efor' callback, since this can now be gotten in any 'QueryT' context via 'queryEnt'.
Parameterized 'emap' and 'efor' by an 'EntityTarget', which allows for calling these functions over specific groups of entities.
Added 'eover': a combination of 'emap' and 'efor'.

0.1.1.0 -- 2018-02-18

Added 'deleteEntity' (function) and 'delEntity' (QueryT setter).

0.1.0.1 -- 2018-02-14

Added 'yieldSystemT' for resuming a 'SystemT' computation later.
Bumped the upper bound on 'base' to 5 (thanks to nek0).

0.1.0.0 -- 2017-12-27

First version. Released on an unsuspecting world.
