## `bat` as a library

- Deprecate `HighlightingAssets::syntaxes()` and `HighlightingAssets::syntax_for_file_name()`. Use `HighlightingAssets::get_syntaxes()` and `HighlightingAssets::get_syntax_for_path()` instead. They return a `Result` which is needed for upcoming lazy-loading work to improve startup performance. They also return which `SyntaxSet` the returned `SyntaxReference` belongs to. See #1747, #1755, #1776, #1862 (@Enselic)
- Remove `HighlightingAssets::from_files` and `HighlightingAssets::save_to_cache`. Instead of calling the former and then the latter you now make a single call to `bat::assets::build`. See #1802, #1971 (@Enselic)
- Replace  the `error::Error(error::ErrorKind, _)` struct and enum with an `error::Error` enum. `Error(ErrorKind::UnknownSyntax, _)` becomes `Error::UnknownSyntax`, etc. Also remove the `error::ResultExt` trait. These changes stem from replacing `error-chain` with `thiserror`. See #1820 (@Enselic)
- Add new `MappingTarget` enum variant `MapExtensionToUnknown`. Refer to its documentation for more information. Also mark `MappingTarget` as `#[non_exhaustive]` since more enum variants might be added in the future. See #1703 (@cbolgiano), #2012 (@Enselic)


# v0.18.3

## Bugfixes

- Bump `git2` dependency to fix build with Rust 1.54, see #1761


# v0.18.2

## Features

- Ignore known backup/template filename suffixes when selecting the syntax, see #1687 (@scop)

## Bugfixes

- Fix for a security vulnerability on Windows. Prior to this release, `bat` would execute programs called `less`/`less.exe` from the current working directory (instead of the one from `PATH`) with priority. An attacker might be able to use this by placing a malicious program in a shared directory where the user would execute `bat`. `bat` users on Windows are advised to upgrade to this version. See #1724 and #1472 (@Ry0taK).

## Other
