A version of this feature rebased onto [Cirdan's new map features branch](http://repo.or.cz/w/openttd/fttd.git) is in the *tracerestrict-cirdan* branch, see [this thread](http://www.tt-forums.net/viewtopic.php?f=33&t=58420)
This is modified to use an extra button in the smallmap window, instead of a console command, and use the current zoom level and display mode of the smallmap window.
* Automated timetables and separation: [imported](http://www.tt-forums.net/viewtopic.php?f=33&t=46391)
* Auto timetabling: Bias timetable adjustment to favour negative adjustments; this is to avoid positive feedback between congestion delays and increased timetable length. Reduce jam detection threshold.
* Auto separation: Fix handling of non-station orders (e.g. waypoints and depots). Change to a per-vehicle setting. Add a company setting to scale vehicle lateness adjustments. No longer set vehicle lateness to 0 if separation fails, instead leave it as it was.
* Timetable GUI: Allow clearing of timetable time fields which are at 0. Allow explicitly setting timetable time fields to 0 without clearing them.
* Add company settings to enable automatic timetabling or separation for new vehicles.
* Allow changing/clearing the timetabled waiting time and max speed of all of a vehicle's orders at once.
* Add client setting to show the remainder ticks in timetable, after dividing to days or minutes.
* Add a company setting to control the number of ticks used in auto-fill timetable rounding.
* Show a company-coloured mark next to vehicles in vehicle list windows, if their owner does not match list owner (imported: by McZapkie) (added in v0.8.0)
* Cargo type orders, this allows order load/unload types to be set per cargo type [imported](https://www.tt-forums.net/viewtopic.php?p=1047749) (added in v0.15.0)
This has been modified so that cargo dest can follow orders with different load/unload types.
* Random town road reconstruction [imported](https://www.tt-forums.net/viewtopic.php?f=33&t=36438) (added in v0.15.0)
This has been modified to change the setting scale. This defaults to off.
* When building tunnels, open new viewports at the far end of the tunnel [imported](https://www.tt-forums.net/viewtopic.php?f=33&t=72639) (added in v0.15.0)
* Various changes to improve handling of savegames which use features not in trunk.
* Savegames from this patchpack are not loadable in trunk.
* Savegames from trunk up to the last savegame version which has been merged into this branch (*jgrpp*) should be loadable in this patchpack.
* Savegames from other branches which use the save/load code in the *save_ext* branch (usually suffixed: *-sx*) which are also merged into this branch (*jgrpp*), or where the added feature is marked as discardable/ignorable, should be loadable in this patchpack.
* Savegames from other patched versions are not loadable in this patchpack except for savegames from the *tracerestrict* branch ([routing restrictions patch](http://www.tt-forums.net/viewtopic.php?f=33&t=73397)),
* Increase maximum permitted vehicle name length (added in v0.17.0), vehicle group name length (added in v0.17.2), and depot/station name lengths (added in v0.20.0).
* Trains break down after colliding with a road vehicle.
#### Caveats for loading savegames from the [Spring 2013 Patch Pack](http://www.tt-forums.net/viewtopic.php?f=33&t=66892):
* This is not guaranteed to be bug free
* Savegames with huge airports are rejected
* Map sizes greater than 16k x 16k are rejected
* PAX signals/stations and traffic lights are cleared, leaving ordinary signals/stations/roads
* Rail ageing/grass on tracks, trip histories, leave order/wait for cargo, auto advertising campaigns, base cost multipliers and other features not in this patch pack are dropped/ignored.
* SpringPP v2.0.102/103 only:
* Savegames which have aircraft approaching, landing, taking off or landed at an oil rig are rejected
* The inflation cost multiplier is adjusted on load
#### A note on branches
Many features have two branches, the *feature* branches are just the raw features, without any modified savegame code.
There are not generally savegame compatible with anything else, except for loading of trunk savegame versions at or before the point where the branch diverged from trunk.
All other load attempts may result in undefined behaviour.
The *feature-sx* branches use the savegame framework in the *save_ext* branch.
