+# Change Log
+
+All notable changes to this project will be documented in this file. (Thus, it
+won't list single bugfixes or improved documentation.)
+
+## [Unreleased]
+
+## [1.1] - 2016-01-18
+
+50 commits.
+
+### Added
+- `CHANGELOG.md` according to [keepachangelog.com](http://keepachangelog.com)
+- Support for [sift](https://sift-tool.org)
+- `<esc>` can be used to cancel the prompt now (in addition to `<c-c>`)
+- `-grepprg` flag (allows more control about the exact command used)
+- For ag versions older than 0.25, `--column --nogroup --noheading` is used
+  automatically instead of `--vimgrep`
+- FAQ (see `:h grepper-faq`)
+- Mappings in quickfix window: `o`, `O`, `S`, `v`, `V`, `T` (see `:h
+  grepper-mappings`)
+- using `-dispatch` implies `-quickfix`
+- The quickfix window uses the full width at the bottom of the screen. Location
+  lists are opened just below their accompanying windows instead.
+
+### Changed
+- Option "open" enabled by default
+- Option "switch" enabled by default
+- Option "jump" disabled by default
+- The "!" for :Grepper was removed. Use `:Grepper -jump` instead.
+- improved vim-dispatch support
+- `g:grepper.tools` had to contain executables before. It takes arbitrary names
+  now.
+- Never forget query when switching tools (previously we remembered the query
+  only when the operator was used)
+
