*	Fix click-digging torches (#5652)	you	2017-04-28
| | | |	Torches are dug instantly again. When the digging time is 0, a delay of 0.15 seconds is added between digging nodes. If the left mouse button is released, the delay is set to 0, thus click-digging.
*	Tools: Fix tool digging speed limit	Hybrid Dog	2017-04-19
|
*	Update server min protocol version to v24 (#5411)	Loïc Blot	2017-03-19
| | | | | | | | | |	* Update server min protocol version to v24 It's based on @sfan5 stats. See https://kitsunemimi.pw/tmp/serverlist_stats_2017-03-17.txt v24 was bumped 25/08/14 and 0.4.11 was released 25/12/14 * Drop protocol v23 and lesser code
*	Make some maps unordered to improve performance	Loic Blot	2016-10-05
| | | | | |	* This permit to improve performance on C++11 builds * use some existing typedefs in tools maps * minor code style changes
*	Change i++ to ++i	David Jones	2015-08-25
|
*	Fix inversion of full_punch_interval	Novatux	2014-07-02
|
*	Omnicleanup: header cleanup, add ModApiUtil shared between game and mainmenu	Kahrl	2013-08-14
