Release Notes: "clock()" is used as a fallback for sub-second timing if "gettimeofday()" is not found. An internal typedef was dropped, and a header declaration for a function that didn't exist was removed. Some build system refactoring was done.

Release Notes: The horrible new getter/setter interface introduced in 2.1.2 has been removed. There are explicit ggtl_set_float() and ggtl_get_float() functions instead now.


Release Notes: Allows sub-millisecond precision for iterative searches. Deprecates the MSEC option in favour of the new TIME option; this takes a double-precision value in seconds, allowing for sub-millisecond precision when doing iterative searches. Introduces new ggtl_getval() and ggtl_setval() functions capable of setting/getting double-precision values.


Release Notes: Documentation and build improvements are the core features of this release. Recursive make is no more, and a new tutorial has been added (ggtltut), showing how to create a simple Tic-Tac-Toe game.


Release Notes: You no longer need to make a copy of each state for games where a move can reliably be undone in place. Support for a clone_state() callback to simplify the semantics of the move() callback. More flexible caching functions and reuse of container nodes. Some documentation improvements.
Test method parametrization for methodologies like smoke testing, equivalence class testing, and analyst driven tests.
