This implements initial support for no_std. Modules such as parsing, saving and rendering are disabled and timing has to be manually provided by registering a global handler. The rendering module is on its way to no_std support as well, but not all Pull Requests to the necessary dependencies are done yet.

See #223 for more information.

- Runs now support custom variables that are key value pairs that either the
  user can specify in the run editor or are provided by a script like an auto
  splitter. [#201](#201)
- There is now an option in the run editor to generate a comparison based on a
  user specified goal time. This uses the same algorithm as the `Balanced PB`
  comparison but with the time specified instead of the personal best.
  [#209](#209)
- Images internally are now stored as is without being reencoded as Base64 which
  was done before in order to make it easier for the web LiveSplit One to
  display them. [#227](#227)
- The Splits.io API is now available under the optional `networking` feature.
  [#236](#236)
- All key value based components share the same component state type now.
  [#257](#257)
- The crate now properly supports `wasm-bindgen` and `WASI`.
  [#263](#263)
- There is now a dedicated component for displaying the comparison's segment
  time. [#264](#264)
- Compiling the crate without `std` is now supported. Most features are not
  supported at this time though.
  [#270](#270)
- [`Splitterino`](https://github.com/prefixaut/splitterino) splits can now be
  parsed. [#276](#276)
- The `Timer` component can now show a segment timer instead.
  [#288](#288)
- Gamepads are now supported on the web.
  [#310](#310)
- The underlying "skill curve" that the `Balanced PB` samples is now exposed in
  the API. [#330](#330)
- The layout states can now be updated, which means almost all of the
  allocations can be reused from the previous frame. This is a lot faster.
  [#334](#334)
- In order to calculate a layout state, the timer now provides a snapshot
  mechanism that ensures that the layout state gets calculated at a fixed point
  in time. [#339](#339)
- Text shaping is now done via `rustybuzz` which is a port of `harfbuzz`.
  [#378](#378)
- Custom fonts are now supported.
  [#385](#385)
- The renderer is not based on meshes anymore that are suitable for rendering
  with a 3D graphics API. Instead the renderer is now based on paths, which are
  suitable for rendering with a 2D graphics API such as Direct2D, Skia, HTML
  Canvas, and many more. The software renderer is now based on `tiny-skia` which
  is so fast that it actually outperforms any other rendering and is the
  recommended way to render.
  [#408](#408)
- Remove support for parsing `worstrun` splits. `worstrun` doesn't support
  splits anymore, so `livesplit-core` doesn't need to keep its parsing support.
  [#411](#411)
- Remove support for parsing `Llanfair 2` splits. `Llanfair 2` was never
  publicly available and is now deleted entirely.
  [#420](#420)
- Hotkeys are now supported on macOS.
  [#422](#422)
- The renderer is now based on two layers. A bottom layer that rarely needs to
  be rerendered and the top layer that needs to be rerendered on every frame.
  Additionally the renderer is now a scene manager which manages a scene that an
  actual rendering backend can then render out.
  [#430](#430)
- The hotkeys are now based on the [UI Events KeyboardEvent code
  Values](https://www.w3.org/TR/uievents-code/) web standard.
  [#440](#440)
- Timing is now based on `CLOCK_BOOTTIME` on Linux and `CLOCK_MONOTONIC` on
  macOS and iOS. This ensures that all platforms keep tracking time while the
  operating system is in a suspended state.
  [#445](#445)
- Segment time columns are now formatted as segment times.
  [#448](#448)
- Hotkeys can now be resolved to the US keyboard layout.
  [#452](#452)
- They hotkeys are now based on `keydown` instead of `keypress` in the web.
  `keydown` handles all keys whereas `keypress` only handles visual keys and is
  also deprecated. [#455](#455)
- Hotkeys can now be resolved to the user's keyboard layout on both Windows and
  macOS. [#459](#459) and
  [#460](#460)
- The `time` crate is now used instead of `chrono` for keeping track of time.
  [#462](#462)
- The scene manager now caches a lot more information. This improves the
  performance a lot as it does not need to reshape the text on every frame
  anymore, which is a very expensive operation.
  [#466](#466) and
  [#467](#467)
- The hotkeys on Linux are now based on `evdev`, which means Wayland is now
  supported. Additionally the hotkeys are not consuming the key press anymore.
  [#474](#474)
- When holding down a key, the hotkey doesn't repeat anymore on Linux, macOS and
  WebAssembly. The problem still occurs on Windows at this time.
  [#475](#475) and
  [#476](#476)
