Balancing

• Reduced time needed for an unit of Automation 2 research from 15 to 5 seconds to compensate for previous change of science packs requirements.

Minor features

• Added --window-size launch option. For example --window-size=1680x1050 more
• Damaging a tree with impact or physical damage generates some leaves.
• Warning icon for logistic chests that are not in a reach of roboport.
• Train stop names are rendered at 45 degrees to better show names.

Bugfixes

• Fixed that ghosts would stay over entities after deconstruction was canceled. more
• Fixed that the controls menu wouldn't use a fixed common width between controls sections.
• Inserter researches now require equal ratios of science pack types.
• Fixed that transferring blueprints from the library could make the headless server crash. more
• Fixed that blueprints could be duplicated when moving to a new version. more
• Fixed progress bar not showing in the entity info panel if the text was too long. more
• Fixed (at least one of the cases) of crashes related to not being able to connect to auth server while joining game. more
• Fixed, possible crash related to changed bounding box of entity by a mod. When the mod is removed (added) the corner of the entity can occupy chunk that doesn't exist yet which would cause a loading error. more
• Fixed that mining sounds and the leaves effect weren't present when mining tree from a car. more
• Fixed possible crash when removing modded rails during save migration. more

Modding

• Mod hotkeys are arranged per-mod.
• Disallowed defining different rail categories for this moment as having more than one will never work properly until we spent some non-trivial time with that, which is not a priority now.

Scripting

• Fixed that item-with-inventory filters wouldn't be preserved when cloned through the Lua API. more
