---------------------------

Version 2.0  [2017-01-25]
-------------------------

  - **Incompatible change**: `--context/-C` is now line based as opposed to
    character based and works just like grep
  - Two new options from grep: `-A/--after-context` and `-B/--before-context`
  - Lines with multiple matches are now printed only once
  - Optional caching of pdf-text for faster operation (by Christian Dietrich)
    This adds a **new dependency**: libgcrypt
  - Bash-completion improvements (by Rainer Müller)
  - Bugfix: Fixed string search (`-F`) now works as advertised with multiple
    patterns
  - Bugfix: Empty pages can now be matched with `^$`
  - Bugfix: The pattern `^` now matches *only* at the beginning of pages
  - Bugfix: Text outside of PDF's CropBox but inside the MediaBox is not
    ignored anymore.
  - Various fixes for BSD support
