Version 0.12.0

Changes:
* OC-Wasm-related crates will be versioned in lockstep, starting from
  0.12.0. This means that equal version numbers should now be compatible
  with each other.

Maintenance:
* Bumped `minicbor` dependency to version 0.21.
* Bumped `ordered-float` dependency to version 4.
* Bumped `oc-wasm-safe` dependency to 0.12.

Version 0.7.0

Dependencies:
* Bumped `minicbor` to 0.20.
* Bumped `oc-wasm-safe` to 0.5.

Version 0.6.1

Fixes:
* Using an `&mut [u8]` as an invocation buffer should now work.

Version 0.6.0

Dependencies:
* Bumped `minicbor` to 0.19.
* Bumped `oc-wasm-safe` to 0.4.

Version 0.5.0

Fixes:
* `minicbor`’s `alloc` feature is only enabled if `oc-wasm-futures`’ own
  `alloc` feature is enabled.

Dependencies:
* Bumped `minicbor` to 0.18.
* Bumped `oc-wasm-safe` to 0.3.

Version 0.4.0

New features:
* The scratch buffer used for encoding parameters and storing return
  values can now be any type that implements the `Buffer` trait, rather
  than only `Vec<u8>`. This trait is always implemented for `&mut [u8]`,
  and it is also implemented for `Vec<u8>` when the `alloc` feature is
  enabled.

Version 0.3.0

New features:
* Component calls now return more detailed error information based on
  the `component` module’s new syscalls `last_exception_message` and
  `last_exception_is_type` from OC-Wasm version 1.12.2-0.3.0.

Dependencies:
* Bumped `minicbor` to 0.15.
* Bumped `oc-wasm-safe` to 0.2.
* Bumped `ordered-float` to 3.

Version 0.2.0

New features:
* sleep::until_signal wakes up when a signal is received.

Fixes:
* Set build target for docs.rs.

Internal:
* Cleanup and optimization.
