Fix matching bug caused by literal optimizations.
* [BUG 256](https://github.com/BurntSushi/ripgrep/issues/256):
Fix bug that caused `rg foo` and `rg foo/` to have different behavior
when `foo` was a symlink.
* [BUG 270](https://github.com/BurntSushi/ripgrep/issues/270):
Fix bug where patterns starting with a `-` couldn't be used with the
`-e/--regexp` flag. (This resolves a regression that was introduced in
ripgrep 0.3.0.)

=====
Bug fixes:

* [BUG 242](https://github.com/BurntSushi/ripgrep/issues/242):
ripgrep didn't respect `--colors foo:none` correctly. Now it does.

=====
This is a new minor version release of ripgrep that includes two breaking
changes with lots of bug fixes and some new features and performance
improvements. Notably, if you had a problem with colors or piping on Windows
before, then that should now be fixed in this release.

**BREAKING CHANGES**:

* ripgrep now requires Rust 1.11 to compile. Previously, it could build on
Rust 1.9. The cause of this was the move from
[Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
for argument parsing.
* The `-e/--regexp` flag can no longer accept a pattern starting with a `-`.
There are two work-arounds: `rg -- -foo` and `rg [-]foo` or `rg -e [-]foo`
will all search for the same `-foo` pattern. The cause of this was the move
from [Docopt to Clap](https://github.com/BurntSushi/ripgrep/pull/233)
for argument parsing.
[This may get fixed in the
future.](https://github.com/kbknapp/clap-rs/issues/742).

Performance improvements:

* [PERF 33](https://github.com/BurntSushi/ripgrep/issues/33):
ripgrep now performs similar to GNU grep on small corpora.
* [PERF 136](https://github.com/BurntSushi/ripgrep/issues/136):
ripgrep no longer slows down because of argument parsing when given a large
argument list.

Feature enhancements:

* Added or improved file type filtering for Elixir.
* [FEATURE 7](https://github.com/BurntSushi/ripgrep/issues/7):
Add a `-f/--file` flag that causes ripgrep to read patterns from a file.
* [FEATURE 51](https://github.com/BurntSushi/ripgrep/issues/51):
Add a `--colors` flag that enables one to customize the colors used in
ripgrep's output.
* [FEATURE 138](https://github.com/BurntSushi/ripgrep/issues/138):
Add a `--files-without-match` flag that shows only file paths that contain
zero matches.
* [FEATURE 230](https://github.com/BurntSushi/ripgrep/issues/230):
Add completion files to the release (Bash, Fish and PowerShell).

Bug fixes:

* [BUG 37](https://github.com/BurntSushi/ripgrep/issues/37):
Use correct ANSI escape sequences when `TERM=screen.linux`.
* [BUG 94](https://github.com/BurntSushi/ripgrep/issues/94):
ripgrep now detects stdin on Windows automatically.
* [BUG 117](https://github.com/BurntSushi/ripgrep/issues/117):
Colors should now work correctly and automatically inside mintty.
* [BUG 182](https://github.com/BurntSushi/ripgrep/issues/182):
Colors should now work within Emacs. In particular, `--color=always` will
emit colors regardless of the current environment.
* [BUG 189](https://github.com/BurntSushi/ripgrep/issues/189):
Show less content when running `rg -h`. The full help content can be
accessed with `rg --help`.
* [BUG 210](https://github.com/BurntSushi/ripgrep/issues/210):
Support non-UTF-8 file names on Unix platforms.
* [BUG 231](https://github.com/BurntSushi/ripgrep/issues/231):
Switch from block buffering to line buffering.
* [BUG 241](https://github.com/BurntSushi/ripgrep/issues/241):
Some error messages weren't suppressed when `--no-messages` was used.

=====
Bug fixes:

* [BUG 226](https://github.com/BurntSushi/ripgrep/issues/226):
File paths explicitly given on the command line weren't searched in parallel.
(This was a regression in `0.2.7`.)
* [BUG 228](https://github.com/BurntSushi/ripgrep/issues/228):
If a directory was given to `--ignore-file`, ripgrep's memory usage would
grow without bound.

=====
Bug fixes:

* Fixed a bug with the SIMD/AVX features for using bytecount in commit
`4ca15a`.

=====
Performance improvements:

* [PERF 223](https://github.com/BurntSushi/ripgrep/pull/223):
Added a parallel recursive directory iterator. This results in major
performance improvements on large repositories.
* [PERF 11](https://github.com/BurntSushi/ripgrep/pull/11):
ripgrep now uses the `bytecount` library for counting new lines. In some
cases, ripgrep runs twice as fast. Use
`RUSTFLAGS="-C target-cpu=native" cargo build --release --features 'simd-accel avx-accel'`
to get the fastest possible binary.

Feature enhancements:

* Added or improved file type filtering for Agda, Tex, Taskpaper, Markdown,
asciidoc, textile, rdoc, org, creole, wiki, pod, C, PDF, C, C++.
* [FEATURE 149](https://github.com/BurntSushi/ripgrep/issues/149):
Add a new `--no-messages` flag that suppresses error messages.
Note that `rg foo 2> /dev/null` also works.
* [FEATURE 159](https://github.com/BurntSushi/ripgrep/issues/159):
Add a new `-m/--max-count` flag that limits the total number of matches
printed for each file searched.

Bug fixes:

* [BUG 199](https://github.com/BurntSushi/ripgrep/issues/199):
Fixed a bug where `-S/--smart-case` wasn't being applied correctly to
literal optimizations.
* [BUG 203](https://github.com/BurntSushi/ripgrep/issues/203):
Mention the full name, ripgrep, in more places. It now appears in
the output of `--help` and `--version`. The repository URL is now also
in the output of `--help` and the man page.
* [BUG 215](https://github.com/BurntSushi/ripgrep/issues/215):
Include small note about how to search for a pattern that starts with a `-`.
