Added

• Implement Debug for ProgressCounter and ProgressCounterTracker. (#1973)
• Added a custom render pass Example. (#1904)
• Add an entry for examples/tiles to the examples readme. (#1978)
• Added UI states/menu example. #1986
• Allow user to specify custom completion function in amethyst_test::WaitForLoad. (#1984)
• Log warning when amethyst_test::WaitForLoad has not completed in 10 seconds. (#1984)
• Derive Copy and PartialEq for amethyst::renderer::resources::Tint. (#2033)
• Derive Hash for amethyst::input::{Button, ControllerButton, ScrollDirection}. (#2041)
• Added Trans::Replace, Trans::NewStack, and Trans::Sequence to the State Machine Transitions. (#2067,#2071)
• Add rendy/gfx-backend log verbosity through configuration. (#1652) (#2048)
• Add Draggable component that can be used with UiTransform to make widgets draggable. (#2080)

Changed

• Use a premultiplied view_proj matrix in vertex shaders. (#1964)
• amethyst_network completely rewritten to provide a new baseline with which to build. ([#1917])
• Cleaned up tiles example. Added rotation and translation tests, fixed raycast debug box. Added default zoom to PROJECT perspective projection since no one knew to zoom out. (#1974)
• TileMaps to_tile and to_world now take an Option<&Transform> that allows them to work if the entire map in translated. (#1987,#1991)
• AmethystApplication::with_fn constraint relaxed from Fn to FnOnce. (#1983)
• ScreenDimensions now consistently reports window size in physical pixels. ([#1988])
• Config::load now returns an error or failure rather than silently falling back to the default config. Same is true for the from_config_file methods on RenderToWindow, WindowBundle, and WindowSystem (#1989)
• Adds get methods to the underlying net::transport resources (#2005)
• Changed SpriteSheetFormat::import_simple to allow importing grid based SpriteSheets (#2023) Migration Note: Rons need to wrap their content in either Grid() or List()
• TileMap to_tile doesn't panic in debug mode. It instead return Result<Point,TileOutOfBounds>. (#2020,#2070)
• Added new Error options for NetworkSimulationEvent.
• Changed amethyst config directory from $HOME/.amethyst to $HOME/.config/amethyst (#2079)
• Changed world_to_screen camera transformation to match inverse of the one in screen_ray (#2057)
• amethyst_input::Axis::Mouse now only has a single radius value. One of the two values was guaranteed to be unused. (#2099)

Deprecated

• Config::load_no_fallback, use Config::load instead (#1989)

Fixed

• Tilemap rotation was incorrect and not transposed. Fixed and uses component rotation. (#1974)
• Config types no longer require a Default impl (#1989)
• Fixed Incorrect path for sprite_camera_follow example (#2004)
• Run System::setup for pausable systems' delegate. (#2029)
• Fixed an incorrect dimensions being used in Tile Encoders, causing bad lookups in assymetric maps in any Z-level besides 0 (#2017)
• Fix encoders dimensional cases and optimize storage space (#2059)
• Fixed off by one issue in to_tile function (#2103)
• Fix dragging UI widgets that have ScaleMode::Percent (#2111)
