Update 4 changelog (patch notes)Backwards compatibility
Saves from Updates 2 and 3 are fully compatible with Update 4. However, due to various changes, existing factories may need to be updated.All mods have to be recompiled and use the new mod manifest file.
 Notable breaking changes
Some pre-existing docking areas might not be working if built near shallow waters. 
New feature: Bridges
Introduced 2 types of bridges: truss and cable-stayed.Bridges have a modular lane system that currently supports either roads or train tracks.Bridges are constructed similarly to train tracks by placing a start point and dragging a bridge.Bridges can be built in 8 cardinal directions, but can be connected to the terrain only in 4 directions.Bridges are fully compatible with all tools, such as copy/paste and blueprints. 
New feature: Amphibious vehicles
Added amphibious trucks and excavators that can traverse and work on water.Unless assigned, amphibious trucks only take jobs that normal trucks fail to do.Amphibious excavators can mine underwater to a depth of -5. 
New feature: Pathfinding for ships
Ships now use pathfinding.Docks can be built anywhere and will work as long as they have access to the map edge.Added ships navigation overlay similar to vehicles.Ships capacity was increased to compensate for longer travel times.World mines capacity was increased as well.

* Fixed a rare case of trains getting stuck at a station with configured train limit.

v0.7.6New content and balancing* Added recipe to digest eggs in anaerobic digester.* Increased orbital cargo limits.* Optimized train driving to reduce slowdowns and waiting by taking other trains’ speed and inertia into account and allowing double-reservations, assuming that trains cannot stop instantly.* Old odd-sized level crossings were marked obsolete and cannot be placed via copy-paste or blueprints.* Improved program startup speed by loading data while the initial loading animation is shown.UI improvements and QoL* Train cars can now be flipped horizontally in the trains designer.* The last selected item in the build menu is now persisted between saves.* Train and line errors now shop-up in the lines manager.* Added quick remove for sorter.* Vehicle mass-replace tool now allows to filter vehicles assigned to tree harvesters.* Unity key can be now used to trigger quick-remove and to toggle boost on a currently selected machine.* Improved construction jobs aggregation when trucks carry materials from deconstruction directly to construction.* Added ability to reassign a deleted station in a schedule.* Added list of trains currently heading to a station to the station inspectors.* Added a list of lines that have this station in their schedule to the station inspector.* All terrain tools now have the flat designation as default.* Copying of connectors via C key is now allowed and supported.Fixes* Level crossings now preserve no-stopping zone state through copy-paste and blueprints.* Trucks should no longer exit in the middle of a level crossing, potentially getting struck in between train tracks.* Fixed memory leak caused by housing previews. This also reduces the memory footprint of house models for settlements with more than 8 houses.* Fixed that camera heights was not properly updated when panning to locations, such as when clicking on notifications.* Fixed arc furnace disappearing from silicon toolbar.* Fixed notifications tabs collapsing to too small height when they are all showing.* Fixed max unity display.* Fixed research complete notification showing +1 tier for incremental research.* Fixed train and generator fuel stats that were incorrectly swapping on each load.* Fixed that train was unable to pass though a loop at the end of bi-directional track if it was marked as critical section.* Fixed rendering of symbol-based languages where the very top was sometimes cut-off.
