Welcome in 2017, dear changelog reader! That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games!

#include "regex.h"
Replacement of internal RegEx with PCRE2 The pattern and replacement matching behaviour has been changed purely due to the nature of switching to a standards-compliant library. One mistake in the previous behaviour was that named groups didn't have a number. This has been corrected. As names are actually just an alias of numbered groups, RegExMatch::get_name_dict() is now get_names() and is a dict referring to the group number it represents. Duplicate names are enabled and the with the first matching instance used. Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was removed.

Replacement of internal RegEx with PCRE2 The pattern and replacement matching behaviour has been changed purely due to the nature of switching to a standards-compliant library. One mistake in the previous behaviour was that named groups didn't have a number. This has been corrected. As names are actually just an alias of numbered groups, RegExMatch::get_name_dict() is now get_names() and is a dict referring to the group number it represents. Duplicate names are enabled and the with the first matching instance used. Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was removed.

RegEx re-implemented as a module Re-wrote nrex as a module using godot-specific parts and new features: * Added string substitutions. * Named groups are now supported. * Removed use of mutable variables in RegEx. RegExMatch is returned instead.
