+
+## 0.2.14 - 2024-06-25
+
+### Fixed
+
+- Fixed parts showing as all black with the Deferred Rendering mod
+
+
+## 0.2.13 - 2024-05-17
+
+### Fixed
+
+- Fixed flag decals sometimes not respecting image aspect ratio
+
+
+## 0.2.12 - 2022-10-31
+
+### Changed
+
+- Updated bundled Shabby to 0.3.0. Does not affect CKAN users
+- Made flag aspect ratio overrides configurable with `ASPECTRATIO` nodes in the config. User flags added to Squad/Flags should now be the correct aspect ratio
+- All decal aspect ratios can now be overriden with the `aspectRatio` field
+
+### Fixed
+
+- Reverted some changes from last version that were causing issues on launch
+
+
+## 0.2.11 - 2022-10-30
+
+### Fixed
+
+- PR by LinuxGuruGamer:
+	- Fixed nullref caused when an entry in `_targets` was null
+	- Fixed memory leak caused by the OnDestroy() methods not being called due to them being virtual
+
+
+## 0.2.10 - 2022-03-14
+
+### Fixed
+
+- Fixed decals not projecting on loading prefabs
+
+### Changed
+
+- Re-enabled projecting onto TransparentFX layer
+
+### Added
+
+- Allowed for regular expressions to be used when blacklisting shaders
+- Added all Waterfall shaders to the shader blacklist when Waterfall is present
+
+
+## 0.2.9 - 2022-03-12
+
+### Fixed
+
+- Fixed text decals breaking when used in symmetry
+- Fixed decals projecting onto the TransparentFX layer, such as Waterfall plumes
+
+
+## 0.2.8
+
+- Update bundled Shabby to support Harmony 2 for compatibility with other mods
+- Update bundled B9PartSwitch to 2.18.0
+
+
+## 0.2.7
+
+- Supported KSP versions: 1.8.x to 1.11.x
+
+### Notes:
+
+- Attaching decal parts in flight using engineer kerbals is not supported.
+
+### Fixed:
+
+- Fixed certain non-ascii strings not rendering correctly under certain circumstances.
+- Yet another attempted fix for the planet text glitch.
+
+
+## 0.2.6
+
+### Fixed:
+
+- Fixed stock flags appearing stretched by forcing their aspect ratio to be correct.
+- Another attempted fix for the planet text glitch.
+
+
+## 0.2.5
+
+### Fixed:
+
+- Fixed line spacing, character spacing, and vertical settings not applying to symmetry counterparts
+
+
+## 0.2.4
+
+### Fixed:
+
+- Fixed red text appearing on planets due to KSP bug by clearing render textures afterwards.
+- Fixed fonts not saving correctly.
+
+### Changed:
+
+- Lowered step size for decal size and depth to 1cm.
+- Changed default max size to 5m.
+- Changed default text decal size to 0.2m
+- Text decals now show as a circle if they contain only whitespace.
+
+
+## 0.2.3
+
+### Fixed:
+
+- Fixed TMP subobjects being deleted, causing fallback fonts to fail in some situations.
+- Started using URL-style encoding for text decals behind the scenes to prevent issues with certain characters.
+- Fixed text decals having zero size when they had only whitespace or an empty string.
+- Fixed decals having drag and causing issues when using FAR.
+- Fixed broken saving of text decals in certain circumstances.
+
+
+## 0.2.2
+
+### Fixed:
+
+- Fixed corrupted text rendering when a vessel loads during a scene change.
+
+
+## 0.2.1
+
+### Changed:
+
+- Pressing enter in the text entry window now types a newline.
+
+### Fixed:
+
+- Renamed font assetbundle. The old extension was causing the game to try to load it twice on Windows due to legacy compatability features.
+- Fixed text rendering on DirectX resulting in black boxes by using ARGB32 instead of RG16 for the render texture in DirectX.
+
+
+## 0.2.0
+
+### New Parts:
+
+- CDL-3 Surface Base Decal: A set of conformal decals based on the symbols from the movie Moon (2009) designed by Gavin Rothery
+- CDL-T Custom Text Decal: A customizable text decal with a variety of fonts 
+
+### Changed:
+
+- New ModuleConformalText module for customizable text
+- Text, font, and style can all be customized, as well as text fill and outline colors and widths
+- Same projection and opacity options as other conformal decals
+- New StandardText decal shader supporting the text module
+- Unified all decal shaders into a single "StandardDecal" shader with variants supporting any combination of bump, specular and emissive maps, plus SDF alphas.
+- Old shaders are remapped to Standard shader plus keywords automatically.
+- New SDF-based antialiasing for when decals extend to their borders, e.g. on opaque flags.
+- New "KEYWORD" material modifier, allowing for shader features to be enabled and disabled.
+- Material modifiers can now be removed in variants by setting `remove = true` inside them.
+
+### Fixed:
+
+- Fixed WIDTH and HEIGHT scale modes being flipped
+- Removed some debug log statements
+- Dependencies:
+- Updated ModuleManager to version 4.1.4
+
+
+## 0.1.4
+
+Supported KSP versions: 1.8.x to 1.10.x
+
+### Fixed:
+
+- Fixed decals rendering onto disabled B9PS part variants
+    - Decals will still not update whan their parent part's B9PS variant is changed, both in flight and in the editor. This is known and awaiting a change to B9PS to be fixed.
+- Fixed decal bounds rendering as dark cubes when shadowed by EVE clouds.
+- Fixed decals being shadowed by EVE clouds, causing the part underneath to appear overly dark.
+
+
+## 0.1.3
+
+### Fixe:
+
+- Fixed decals being able to be scaled down to 0
+
+### Changed:
+
+- Made decal bounds no longer collide in flight, this is done by repurposing layer 31 (which is configurable in the ConformalDecals.cfg file)
+- Decals will now be unselectable in flight by default. This can be disabled with the `selectableInFlight` value in ConformalDecals.cfg, or in the module config itself.
+- Decal parts will now destroy themselves automatically when the parent part is destroyed
+- Small refactor of node parsing code
+    - Colors can now be specified in hex (#RGB, #RGBA, #RRGGBB, or #RRGGBBAA) or using the colors specified in the XKCDColors class
+
+
+## 0.1.2
+
+### Fixed:
+
+- Disabled writing to the zbuffer in the decal bounds shader. Should fix any issues with Scatterer or EVE.
+
+
+## 0.1.1
+
+### Fixed:
+
+- Fixed flag decal not adjusting to new texture sizes immediately.
+- Fixed decal bounds being visible on launch.
+- Fixed decal bounds being visible in the part icon.
+
+
+## 0.1.0
+
+Initial release!
+
+### New Parts:
+
+- CDL-F Flag Decal: Conformal flag decal, which uses either the mission flag or a flag of your choosing.
+- CDL-1 Generic Decal: A set of conformal generic decals for planes and rockets
+- CDL-2 Semiotic Standard Decal: A set of conformal decals based on the Semiotic Standard for All Commercial Trans-Stellar Utility Lifter and Transport Spacecraft designed by Ron Cobb for the movie Alien

-v0.2.7
-------
-- Supported KSP versions: 1.8.x to 1.11.x
-- Notes:
- - Attaching decal parts in flight using engineer kerbals is not supported.
-- Fixes:
- - Fixed certain non-ascii strings not rendering correctly under certain circumstances.
- - Yet another attempted fix for the planet text glitch.
-
-v0.2.6
-------
-- Fixes:
- - Fixed stock flags appearing stretched by forcing their aspect ratio to be correct.
- - Another attempted fix for the planet text glitch.
-
-v0.2.5
-------
-- Fixes:
- - Fixed line spacing, character spacing, and vertical settings not applying to symmetry counterparts
-
-v0.2.4
-------
-- Fixes:
- - Fixed red text appearing on planets due to KSP bug by clearing render textures afterwards.
- - Fixed fonts not saving correctly.
-- Changes:
- - Lowered step size for decal size and depth to 1cm.
- - Changed default max size to 5m.
- - Changed default text decal size to 0.2m
- - Text decals now show as a circle if they contain only whitespace.
-
-v0.2.3
-------
-- Fixes:
- - Fixed TMP subobjects being deleted, causing fallback fonts to fail in some situations.
- - Started using URL-style encoding for text decals behind the scenes to prevent issues with certain characters.
- - Fixed text decals having zero size when they had only whitespace or an empty string.
- - Fixed decals having drag and causing issues when using FAR.
- - Fixed broken saving of text decals in certain circumstances.
- 
-v0.2.2
-------
-- Fixes:
- - Fixed corrupted text rendering when a vessel loads during a scene change.
-
-v0.2.1
-------
-- Changes:
- - Pressing enter in the text entry window now types a newline.
-- Fixes:
- - Renamed font assetbundle. The old extension was causing the game to try to load it twice on Windows due to legacy compatability features.
- - Fixed text rendering on DirectX resulting in black boxes by using ARGB32 instead of RG16 for the render texture in DirectX.
-
-v0.2.0
-------
-- New Parts:
- - CDL-3 Surface Base Decal: A set of conformal decals based on the symbols from the movie Moon (2009) designed by Gavin Rothery
- - CDL-T Custom Text Decal: A customizable text decal with a variety of fonts
-- Changes:
- - New ModuleConformalText module for customizable text
-  - Text, font, and style can all be customized, as well as text fill and outline colors and widths
-  - Same projection and opacity options as other conformal decals
-  - New StandardText decal shader supporting the text module
- - Unified all decal shaders into a single "StandardDecal" shader with variants supporting any combination of bump, specular and emissive maps, plus SDF alphas.
-  - Old shaders are remapped to Standard shader plus keywords automatically.
-  - New SDF-based antialiasing for when decals extend to their borders, e.g. on opaque flags.
- - New "KEYWORD" material modifier, allowing for shader features to be enabled and disabled.
- - Material modifiers can now be removed in variants by setting `remove = true` inside them.
-- Fixes:
- - Fixed WIDTH and HEIGHT scale modes being flipped
- - Removed some debug log statements
-- Dependencies:
- - Updated ModuleManager to version 4.1.4
-
-v0.1.4
-------
-- Supported KSP versions: 1.8.x to 1.10.x
-- Fixes:
- - Fixed decals rendering onto disabled B9PS part variants
-   - Decals will still not update whan their parent part's B9PS variant is changed, both in flight and in the editor. This is known and awaiting a change to B9PS to be fixed.
- - Fixed decal bounds rendering as dark cubes when shadowed by EVE clouds.
- - Fixed decals being shadowed by EVE clouds, causing the part underneath to appear overly dark.
-
-v0.1.3
-------
-Fixes:
-- Fixed decals being able to be scaled down to 0
-
-Changes:
-- Made decal bounds no longer collide in flight, this is done by repurposing layer 31 (which is configurable in the ConformalDecals.cfg file)
-- Decals will now be unselectable in flight by default. This can be disabled with the `selectableInFlight` value in ConformalDecals.cfg, or in the module config itself.
-- Decal parts will now destroy themselves automatically when the parent part is destroyed
-- Small refactor of node parsing code
-  - Colors can now be specified in hex (#RGB, #RGBA, #RRGGBB, or #RRGGBBAA) or using the colors specified in the XKCDColors class
-
-v0.1.2
-------
-Fixes:
-- Disabled writing to the zbuffer in the decal bounds shader. Should fix any issues with Scatterer or EVE.
-
-v0.1.1
-------
-Fixes:
-- Fixed flag decal not adjusting to new texture sizes immediately.
-- Fixed decal bounds being visible on launch.
-- Fixed decal bounds being visible in the part icon.
-
-v0.1.0
-------
-Initial release!
-
-New parts:
-- CDL-F Flag Decal: Conformal flag decal, which uses either the mission flag or a flag of your choosing.
-- CDL-1 Generic Decal: A set of conformal generic decals for planes and rockets
-- CDL-2 Semiotic Standard Decal: A set of conformal decals based on the Semiotic Standard for All Commercial Trans-Stellar Utility Lifter and Transport Spacecraft designed by Ron Cobb for the movie Alien
