* `company-backends`: `prefix` command can return `t` in the cdr.
* `company-clang-begin-after-member-access`: New option.

* Two `company-elisp` tweaks.

## 2013-04-01 (0.6.6)

* `company-elisp` doesn't offer completions when typing the name and the
  arguments of a new function or macro definition, allowing to fall back to
  other back-ends like `company-dabbrev-code`.

## 2013-03-30 (0.6.5)

* Fixed keybindings when running in a terminal.
* `company-elisp-show-locals-first`: new customizable variable.
* `company-elisp` shows more accurate and comprehensive candidates list.

## 2013-03-26 (0.6.4)

* `company-eclim` shows valid completions after an opening paren.
* Expanded template does not get removed until the point leaves it.  After your
  input the last argument in a method call expanded by `company-eclim`, you can
  press `<tab>` once more, to jump after the closing paren.  No other bundled
  back-ends are affected.

## 2013-03-25 (0.6.3)

* New tooltip face colors used on themes with light background.
* Pseudo-tooltip stays up-to-date when text is inserted after the point.

## 2013-03-23 (0.6.1)

* Documented `init` and `post-completion` back-end commands.
* `company-eclim` and `company-clang` only expand the template on explicit user
  action (such as `company-complete-{selection,number,mouse}`).
* `company-template` has some breaking changes.  When point is at one of the
  fields, it's displayed at the beginning, not right after it; `<tab>` jumps to
  the next field, `forward-word` and `subword-forward` remappings are removed;
  when you jump to the next field, if the current one hasn't been edited, the
  overlay gets removed but the text remains.
* `company-eclim` shows method overloads and expands templates for calls.
* `company-clang-objc-templatify` does not insert spaces after colons anymore.
* `company-clang` is now only initialized in supported buffers.
  So, no error messages if you don't have Clang until you open a C file.
* `company-clang` recognizes Clang included in recent Xcode.
* New commands `company-select-previous-or-abort` and
  `company-select-next-or-abort`, bound to `<up>` and `<down>`.

## 2013-03-19 (0.6)

* Across-the-board bugfixing.
* `company-pysmell` is not used by default anymore.
* Loading of `nxml`, `semantic`, `pymacs` and `ropemacs` is now deferred.
* Candidates from grouped back-ends are merged more conservatively: only
  back-ends that return the same prefix at point are used.
* `company-clang` now shows meta information, too.
* Some performance improvements.
* Fixed two old tooltip annoyances.
* Instead of `overrriding-terminal-local-map`, we're now using
  `emulation-mode-map-alists` (experimental).  This largely means that when the
  completion keymap is active, other minor modes' keymaps are still used, so,
  for example, it's not as easy to accidentally circumvent `paredit-mode`
  when it's enabled.
* `company-elisp` has seen some improvements.
* Added `company-capf`: completion adapter using
  `completion-at-point-functions`.  (Stefan Monnier)
