# Changes in version 0.3.0.0
* Some performance improvements, including avoiding quadratic
slowdown with left-associated binds.
* Documentation cleanup; Haxl.Core is the single entry point for the
core and engine docs.
* (>>) is now defined to be (*>), and therefore no longer forces
sequencing. This can have surprising consequences if you are
using Haxl with side-effecting data sources, so watch out!
* New function withEnv, for running a sub-computation in a local Env
* Add a higher-level memoization API, see 'memo'
* Show is no longer required for keys in cachedComputation
* Exceptions now have `Eq` instances
