We want to be able to perfectly roundtrip a time, and since we already switched to using only integers when formatting a time, we are able to store them in a splits file in full precision, down to the nanosecond. We want to be able to parse them again without any loss of precision. In the PRs for formatting a time we gained a bunch of speed by switching to the integers. I haven't done any benchmarks here, but improving the parsing speed isn't the point of this PR anyway.

- The `livesplit-hotkey` crate is now documented. (@CryZe) [#479](#479) - Not every key press emits a scan code on Windows. For those the virtual key code is now translated to a scan code. (@CryZe) [#480](#480) - Time parsing is now a lot more robust, handles more edge cases, and is also a lot more accurate. (@CryZe) [#483](#483) and [#578](#578) - When parsing a GDI based font name, platforms other than Windows now don't attempt to parse "normal" as part of the font name anymore as it is too ambigious. It could either refer to a font weight or stretch. (@kadiwa4) [#487](#487) - The text engine can now be customized. You can either provide your own text engine or use the one provided by `livesplit-core`. The one provided is now behind the `path-based-text-engine` and converts all glyphs to paths that can easily be drawn. (@CryZe) [#495](#495) - The path based text engine now caches the width of digits for tabular numbers, as well as the ellipsis glyph and its width, so that they can be layed out faster. (@kadiwa4) [#490](#490) and [#499](#499) - On Windows GDI is now used to resolve GDI based font names. (@CryZe) [#500](#500) - (Total) Possible Time Save now properly indicates that it's updating frequently. This results in faster rendering times. (@kadiwa4) [#501](#501) - Initial support for auto splitting has landed in `livesplit-core`. Auto splitters are provided as WebAssembly modules. Support can be activated via the `auto-splitting` feature. (@P1n3appl3) [#477](#477) - Auto splitting is also supported via the C API when activating its `auto-splitting` feature. (@DarkRTA) [#503](#503) - A watchdog for the Auto Splitting Runtime was added which unloads scripts that aren't responsive. (@CryZe) [#528](#528) - Splits and layouts can now be parsed and saved on `no_std` platforms. (@CryZe) [#532](#532) - The splits component column labels can now be queried via the C API. (@MichaelJBerk) [#526](#526) - The Software Renderer is now supported on `no_std` platforms. (@CryZe) [#536](#536) - The parsers are now faster because they don't allocate as much memory anymore. (@CryZe) [#546](#546) - The auto splitters have unstable support the `WebAssembly System Interface` via the `unstable-auto-splitting` feature. (@CryZe) [#547](#547) - The Timer component can now use the color of the delta for its background. (@Hurricane996) [#539](#539) - The splits component now takes the font into account when calculating the width of the columns. (@Hurricane996) [#550](#550) - The `Resource Allocator` now decodes the images, allowing the underlying renderer to do the encoding by itself. (@CryZe) [#562](#562) - Cargo's `--crate-type` parameter is now used to build the C API. (@CryZe) [#565](#565) - The columns of the splits component can now show the custom variables. (@CryZe) [#566](#566) - On the web, the `keydown` event may not always pass a `KeyboardEvent` despite the specification saying that this should be the case. This is now properly handled. (@CryZe) [#567](#567) - An integer overflow in the `FuzzyList` used for searching game and category names has been fixed. (@CryZe) [#569](#569) - The way the background is handled in the Detailed Timer component has been fixed. (@CryZe) [#572](#572) - The times are now formatted as strings without going through floating point numbers which increases both the correctness and the performance. (@CryZe) [#576](#576) - Instead of using `core::fmt` formatting machinery to format the times as strings, we now use a custom implementation that's much faster. (@CryZe) [#577](#577) and [#580](#580) - Holding down a hotkey on Windows now doesn't cause it to be triggered over and over again. Other platforms already behaved this way. (@CryZe) [#584](#584) - The `base64` crate is now replaced with `base64-simd` which uses SIMD to speed up the decoding of the images. (@CryZe) [#585](#585) - Splits from `SpeedRunIGT`, which is a Minecraft speedruning mod, can now be parsed. (@CryZe) [#591](#591) - It turns out using `evdev` for the hotkeys on Linux requires the user to be in the `input` group, which is not always the case. Therefore we now fall back to `X11` if `evdev` is not usable. (@CryZe) [#592](#592) - When an auto splitter wants to attach to a Process by name, the start time and process id are now used to prioritize duplicate processes. (@Eein) [#589](#589) - It is now possible to resolve the key codes to the particular name of the key based on the current keyboard layout on Linux and the web. This was already the case on Windows and macOS. (@CryZe) [#594](#594) and [#595](#595) - It is now possible to trust the user of the C API to always pass valid UTF-8 strings to the C API via the optional `assume-str-parameters-are-utf8` feature. This is also always the case when using WebAssembly on the web. This improves the performance because no validation of the strings is necessary. (@CryZe) [#597](#597) - There is now a new `max-opt` cargo profile that can be used to maximally optimize the resulting executable. The release profile is now using its default configuration again. (@CryZe) [#598](#598) - When encountering images `livesplit-core` checks their dimensions to potentially automatically shrink them if they are larger than necessary. It turns out that checking the dimensions of PNG images was a lot less efficient than it could have been. This even improves parsing speed of entire splits files by up to 30%. (@CryZe) [#600](#600) - The documentation now uses links to types mentioned. (@Eein) [#596](#596) - Auto splitters can now query size of the modules of a process. (@CryZe) [#602](#602) - The log messages emitted by auto splitters can now be consumed directly instead of always being emitted via the `log` crate. (@CryZe) [#603](#603) - The auto splitters can provide settings that can be configured. For now the auto splitters need to be reloaded when the settings change. (@CryZe) [#606](#606) - The file path used to be tracked in the `Run`, but no frontend even used this. So it has been removed. (@CryZe) [#616](#616) - The documentation states that the title component's lines store the unabbreviated line as their last element. This was not actually the case and has been fixed. (@DarkRTA) [#615](#615)
