### 0.6.2

* Rewrote the build script's command parsing to work with Rust 1.41
  * See https://github.com/jmacdonald/amp/issues/173 for details

### 0.6.1

* Added the ability to choose a syntax definition for the current buffer
* Updated `git2` dependency
* Disabled unused `git2` features, removing transitive openssl dependency

### 0.6.0

* Added more information to quick start guide (thanks, John M-W!)
* Added snapcraft build file (thanks, Alan Pope!)
* Added proper delete key support (thanks, Jérôme Martin!)
* Added https support to GitHub URL generation command (thanks, king6cong!)
* Use a vendored version of OpenSSL (thanks, Cecile Tonglet!)
* Fixed buffer::outdent_line when using hard tabs (thanks, Gaby!)
* Fixed an issue where user syntax definitions were loaded after argument buffers (#122)
* Update to compile with Rust 2018 edition
* Added keybindings to support jumping directly into symbol and open modes from search mode
* Handle missing themes gracefully, falling back to default (#149)
* Migrate from termbox library to termion
  * Removes termbox's build process Python dependency
  * Adds 24-bit colour support
  * Built a TerminalBuffer to allow successive screen updates within a single
    render cycle without introducing screen flicker.
    * Improves support for UTF-8 grapheme clusters.
      * Since termbox uses 32-bit char values to represent cells, anything larger
        than 32 bits, even if spilled over into adjacent cells, will be overwritten
        by adjacent characters. The new TerminalBuffer type uses Cow<&str> values,
        allowing arbitrary-length cells, which will be streamed to the terminal
        and overlaid as a single visible "character", without any loss of data.
    * Created a new Presenter type to hold the contents of this buffer, as well
      as extract common bits of functionality from various mode-specific presenters.
