invocations.

<!-- categories: Added, Removed, Changed, Deprecated, Fixed, Security -->

## [0.12.2] - 2021-04-25

### Fixed

- Cached values no longer inherit liveness from their dependents if those dependents were
  initialized in the current GC revision. This prevented some values from being GC'd at the correct
  time. See [#238](https://github.com/anp/moxie/issues/238).

## [0.12.1] - 2020-12-28

### Added

- `wasm-bindgen` cargo feature which enables correct usage of parking_lot on wasm32 targets.

## [0.12.0] - 2020-08-09

### Changed

- `CacheMiss` handles initialization of borrowed inputs for storage, this removes arguments from
  some lower-level functions.

## [0.11.0] - 2020-08-08

### Fixed

- Nested queries to `SharedLocalCache`/``SharedSendCache` have their intermediate dependencies
  retained as long as a transitive dependent is used in a revision.

## [0.10.0] - 2020-07-19

### Added

- Crate extracted from `topo::cache` module.
- `{LocalCache,SendCache}::cache` wraps `cache_with` for types that impl `Clone`.
- `{LocalCache,SendCache}::hold` wraps `cache_with` for queries that don't need returns.
- `CacheMiss` struct is used to ensure storage happens where the failed lookup happened.

### Changed

- Rename `Cache`/`SharedCache` to `SendCache`/`SharedSendCache`.
