Version release notes (from GitHub):
# Packages

- Packages for clingo are available in the Linux distributions [Debian][deb], [Ubuntu][ubu], and [Arch Linux (AUR)][aur].
- For Mac OS X, clingo packages are available in [homebrew][hbr] and [macports][mac].

# Changes

* change C API to use numeric instead of symbolic literals
  * affects assumptions and assigning/releasing externals (breaks backward compatibility)
  * added overloads to C++, python and lua API to support both numeric and symbolic version (preserves backward compatibility for most code)
* the python, C and C++ APIs now allow for customizing clingo by implementing a custom main function but reusing the rest of the application including the standard output
* add API function to detect conflicting programs
* add message logger to python and lua interface
* add support for primes in the beginning of identifiers and variable names
* add per solver registration of watches during propagator initialization
* add a directive to selectivel suppress undefined atom warnings
* add support for user defined statistics
* add _to_c functions for python API to be able to call C functions from python
* only create ground representations for requested program parts when grounding (NixOS#71)
* improve program observer (NixOS#19)
* support for binary, octal, and hexadecimal numbers (NixOS#65)
* the backend has to be opened/closed now
* release python's GIL while grounding (NixOS#82)
* TruthValue.{True,False} becomes TruthValue.{\_True,\_False} in python API
* improve API and it's documentation
