*	atlatc: fix operation panel not in ndb, add warning when node is not found ↵	orwell96	2019-11-06
| | | |	on queue run
*	Add lines scheduler for reliable railway-time scheduling(which is also safer ↵	orwell96	2019-08-26
| | | |	than the atlatc scheduler) and document new atlatc functions
*	Shunting mode now couples trains on collision.	Gabriel Pérez-Cerezo	2019-08-11
| | | |	Trains now get coupled when one of them is in coupling mode.
*	Document luaatc decoupling	Gabriel Pérez-Cerezo	2019-08-11
|
*	Add decoupling to luaatc	Gabriel Pérez-Cerezo	2019-08-11
|
*	RWTs can be specified in any form, unify converters, repeating time handling	orwell96	2019-06-19
|
*	Railway Time: atlatc interface, improve util functions	orwell96	2019-06-19
|
*	Fix occurences of old lzb_invalidate	orwell96	2019-04-23
|
*	Lift restrictions for date() function in atlatc	orwell96	2019-02-22
|
*	Force LZB Halt setting	orwell96	2019-02-05
|
*	Add getter/setter for routingcode in LuaATC	orwell96	2019-01-15
|
*	Add set_aspect function	orwell96	2018-11-20
| | | | |	This allows incorporating signals implementing the signal API in LuaAutomation projects Note that it circumvents TCB assignments (a signal assigned to a TCB can be set to green even if no route is set
*	Add Note regarding pcnaming and interlocking signals	orwell96	2018-11-20
|
*	Make "Line" property accessible from OBC and gettable via LATC, change ↵	orwell96	2018-11-20
| | | |	subway wagon texture handling
*	Allow pcnaming for any signals	orwell96	2018-11-05
|
*	Fix node database ATC rail bug	orwell96	2018-10-17
| | | | | | |	After successfully registering newly-placed ATC rails in the nodedb, the rail's after_place_node() callback (local apn_func()) immediately cleared it again by passing a "node" object that was actually a player object and thus had no "name" or "param2" to ndb.update(), which it handled how it should not in this situation. Since those ndb.update calls were unnecessary anyways, I removed them completely.
*	Address H#60, H#17, M#18 and M#7	orwell96	2018-10-17
| | | | | | |	duplicate "message" to "msg" make operation panel "cracky" remove inexistent dtime_s parameter add bones:bones to the list of not_blocking_trains nodes
*	Fix H#66 (Hemiptera 66) crash on missing double_conn match	orwell96	2018-10-17
|
*	Add signal safety control override, restructure control system	orwell96	2018-10-10
|
*	Add LuaAutomation interface functions for interlocking routesetting and ↵	orwell96	2018-08-24
| | | | | |	aspect requesting. This allows to incorporate interlocking to automated systems
*	(Note added, merge in next commit)	orwell96	2018-08-24
|
*	Move passive API to the advtrains core	orwell96	2018-08-16
| | | |	to remove dependency of interlocking on luaautomation
*	Correct some documentation	orwell96	2018-06-14
|
*	Mainly make collisions and coupling work	orwell96	2018-06-14
| | | |	Missing: ATC stuff, yaw problems
*	Add digiline interface and is_passive function to LuaATC	orwell96	2018-04-25
|
*	Rewrite rail connection system...	orwell96	2017-12-18
| | | | | | | | |	...to support an arbitrary number of connections for rails, which leads to these new features: - switches now get recognized by the trackworker correctly - ability to add real rail crosses During this, I also rewrote the rail registering system and the conway function (important part of path prediction) Note, developers: the track preset format changed, you might need to rewrite them according to the presets in tracks.lua if you wrote your own (possibly breaks advcarts)
*	Add missing documentation for set_line	orwell96	2017-10-25
|
*	Implement multi-occupation in detector.on_node table to finally fix collisions	orwell96	2017-10-25
|
*	Set wagon line number	Gabriel Pérez-Cerezo	2017-10-23
|
*	Remove zip release files, move mod to root, exclude assets from Makefile (#92)	rubenwardy	2017-09-20
