Changes since 0.18.2:

v0.19.0

Performance

 * Reduce startup time in loop-through mode (e.g. when redirecting output) by
   90%. See #1747 (@Enselic)
 * Load themes lazily to make bat start 25% faster when disregarding syntax load
   time. See #1969 (@Enselic)
 * Python syntax highlighting no longer suffers from abysmal performance in
   specific scenarios. See #1688 (@keith-hall)
 * Fix for poor performance when ANSI escape sequences are piped to bat, see
   #1596 (@eth-p)
 * Fix for incorrect handling of ANSI escape sequences when using --wrap=never,
   see #1596 (@eth-p)
 * Load custom assets as fast as integrated assets, see #1753 (@Enselic)

Features

 * Support for x:-delta (minus) syntax in line ranges (e.g. 20:-10). See #1901
   (@bojan88)
 * Support for --ignored-suffix argument. See #1892 (@bojan88)
 * $BAT_CONFIG_DIR is now a recognized environment variable. It has precedence
   over $XDG_CONFIG_HOME, see #1727 (@billrisher)
 * Support for x:+delta syntax in line ranges (e.g. 20:+10). See #1810
   (@bojan88)
 * Add new --acknowledgements option that gives credit to theme and syntax
   definition authors. See #1971 (@Enselic)
 * Include git hash in bat -V and bat --version output if present. See #1921
   (@Enselic)

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
