Significant Changes:

• New: PNG decoder handles 16-bit alpha PNG files.

• Change: Add warning for probably incorrect rotation direction vector in CSV / B3D objects.
• Change: Improve the error logged when an incorrect argument separator is used in CSV / B3D objects
• Change: Improve color handling in X parsers.
• Change: If a critical error is encountered on OS-X, we attempt to show a system error dialog.
• Change: Make Zuki capabilities detection less strict in DenshaDeGo! Input. (MarcRiera)
• Change: Large number of internal improvements and fixes in MSTS Shapes.
• Change: Improve draw speed when events overlay is active and large numbers of events are present.

• Fix: .Net plugins might not load correctly.
• Fix: Issue when attempting to repeatedly change to a missing interior view.
• Fix: Use invariant culture when parsing vectors from a string in XML.
• Fix: Issue with RailAnnouceAll command.

Significant Changes:

• Change: Implement D3DDECL_USAGECOLOR in NewXParser.
• Change: Apply consist reversal before placing TFO.
• Change: Allow using MSTS shapes in animated files; contained animations will be set to frame zero.
• Fix: TrackFollowerFunction with no axles incorrectly flipped (Not fixed right in 1.11.2.3)
• Fix: Some animated objects containing sounds might not parse correctly.
• Fix: Some palleted PNG files with an odd width, less than a scanline length failed to load.
• Fix: VSync option not remembered. (AmberIsFrozen)
• Hacks: Update brackets in station name fix.
• Hacks: Fix some buggy objects in Ryoso.
• Hacks: Fix transparency in Kurumigasaki Railway signs.
• Compatability: Add a large number of files to the compatability database.

Significant Changes:

• Fix: Several edge-cases in the new block parser.
• Fix: Permille gradient display incorrect.
• Fix: TrackFollowerFunction with no axles set failed to work correctly.
• Fix: An object using an invalid (non-zero) state as hidden could be incorrectly shown on introduction.
• Change: Pre-load all variants of a texture, not just ClampClamp if preloading is selected.
• Change: Improve vertex de-duplication algorithm for a considerable speedup.
• Change: Update openal-soft to v1.24.3
• Change: Update OpenGL related error strings to reflect minumum GL4.3 in new renderer.

This build contains one significant new feature: Particle (smoke) trails.

These are only available for XML based trains, and smoke volume is currently only power based, but more subjects etc. are planned to be added.

The current version of this build is 1.11.2.2, which fixes an issue launching the game on systems using the OpenGL main menu solely.

Significant Changes:

• New: Add particle system to XML trains.
• New: Implement DeclData template in the NewXParser
• New: Add RailAnnounce and RailAnnounceAll commands.
• New: Add PreTrain / RunInterval to TFO XML.
• Change: Use the new block parser in a couple more places.
• Change: Force close viewer windows under Mono to stop hanging processes.
• Change: Remove the use Prism.Mvmm library, by cloning the class we use- The current version is no longer MIT licenced.
• Change: Improve the handling of visibility update locks on reload in Route Viewer.
• Change: Use lower object optimisation threshold for the BVE5 Seoul Metro route.
• Change: Combine marker drawing routines into the common renderer.
• Fix: IgnoreW should be true for root matrix transforms in AssimpXParser.
• Fix: Potential SanYingInput crash on joysticks with more buttons than axis.
• Fix: Correct some erroneous error text in the CSV / RW route parser.
• Fix: Remove a couple of spurious errors generated by the new block parser.
• Fix: Directly creating a texture with an invalid path could crash.
• Fix: Correct blending of object based backgrounds using partial transparency.

This build primarily contains small fixes, but should be noted as containing one potentially breaking change to the RouteLimit animated instruction, in the edge-case where no limit is set.

Significant Changes:

• New: Add SectionLimit animated instruction, which returns the current signal speed limit, or -1 if unlimited.
• Fix: Add guard to prevent crash if BC pressure reaches zero.
• Fix: On-screen messages for permissive section not shown.
• Fix: A state with a missing object file would not be correctly hidden. (Introduced in 1.11.1.4)
• Fix: Loading an animated object with sounds could potentially fail in some cases.
• Fix: Incorrect node passed when loading acceleration curves from XML.
• Change: Considerable internal work to abstract the motor / trailer properties.
• Change: Update version of ReactiveProperty library used by TE2.
• Change: A wide version of the handle overlay texture is used when appropriate.
• Change: Update pt-PT language file (Alexandre Carvalho)
• Potentially Breaking Change: If no speed limit is currently set, the RouteLimit animated instruction now returns -1. Previously, it returned double.MaxValue, which caused a crash when combined with other mathematical operations.
• Change: Remove an unnecessary re-init of the renderer when reloading in viewers.
• Change: Add better handling for edge-case where both Volume / Pitch and VolumeFunction / PitchFunction are used in an animated sound.
• Change: Merge some sound related changes into Route Viewer.
