# Defold 1.12.3 NOTE: From this release on, we’ve moved away from having the editor deployed under `editor-alpha` channel, and instead use the `stable` channel. You don’t need to do anything special, other than update the editor as usual, and it will update itself to the stable channel. ## ⚠ Important note about changes to resource.get\_atlas() and resource.set\_atlas() If you manipulate or query an atlas at runtime using `resource.get_atlas()`, `resource.set_atlas()` or `resource.create_atlas()` it is important that you pay extra attention to the change made to the atlas animation data. Previous versions of Defold returned a `frame_start` and `frame_end` per animation in the `animations` list. The `frame_start` and `frame_end` values were very unreliable and only worked correctly in the case when the order of images in the `geometries` list exactly matched the sequence of animation frames from `frame_start` to `frame_end`. In cases when animations aren’t sequentially ordered the `frame_start` and `frame_end` simply can’t be used to represent the animation frames. The use of `frame_start` and `frame_end` was an oversight in the initial design of the API. **In this version of Defold we’ve decided to deprecated the `frame_start` and `frame_end` fields in favour of a list of animation `frames`** containing indices to the geometries of the animation. If you have code which works with single frame animations it is still easy to get the get “image” used by the animation by getting the first value from the `frames` list: ```lua -- defold 1.12.2 and older: local geometry_index = anim.frame_start -- defold 1.12.3 local geometry_index = anim.frames[1] ``` More information in the pull request: > > > This change adds \`frames\` as a valid key in the \`animations\` table received from… \`resource.get\_atlas()\` or sent to \`resource.set\_atlas()\` / \`resource.create\_atlas()\`.

It will convert internal paths from the form `/very/long/path/to/my/resource.type` into `/0123/4567/890a/bcde.type`, so the savings will vary between projects. Note: Currently, this option is experimental. To use this feature, pass `--experimental-path-minification` to `bob.jar` when bundling. **FIX** : ([#11930](https://github.com/defold/defold/pull/11958)) **‘Fix strange sprite behavior when change atlas in runtime’** by ekharkunov Fix sprite strange behavior when sprite atlas was changed in runtime. **FIX** : ([#11328](https://github.com/defold/defold/pull/12042)) **‘Reduce number of dispatches needed for GUI text nodes’** by Jhonnyg Text nodes in the GUI component requires less dispatch calls now. **FIX** : ([#9722](https://github.com/defold/defold/pull/11965)) **‘Incorrect attribute values for instancing’** by Jhonnyg Using materials with custom vertex formats for models together with overriding materials in a render script can now render correctly. **FIX** : ([#11953](https://github.com/defold/defold/pull/11983)) **‘Fix `gui.set_screen_position()` when Adjust Reference is Disabled’** by AGulev Fixed an issue where `gui.set_screen_position()` did not work correctly for root nodes when `Adjust Reference` was set to Disabled in a GUI component. **FIX** : ([#12009](https://github.com/defold/defold/pull/12009)) **‘Make sure `shader.exclude_gles_sm100` is taken into account in `AndroidManifest.xml`’** by AGulev The `shader.exclude_gles_sm100` checkbox in `game.project` disables generation of OpenGL ES 2.0 compatible shaders, which makes this API unsupported. This setting should also be reflected in `AndroidManifest.xml`, so Google Play knows that such devices are not supported. ⚠ If you are using a custom AndroidManifest.xml file, make sure to update it. Replace ```xml ``` with ```xml {{#shader.exclude_gles_sm100}} {{/shader.exclude_gles_sm100}} {{^shader.exclude_gles_sm100}} {{/shader.exclude_gles_sm100}} ``` **FIX** : ([#12034](https://github.com/defold/defold/pull/12034)) **‘Added dmGraphics::VulkanGetImage and dmGraphics::VulkanGetImageView to dmsdk’** by JCash This allows the developer to get a native `VkImage` and `VkImageView` from a `dmGraphics::HTexture`.

This has now been changed so that we cache the sampler settings and only apply these when the sampler state has changed. In this sample scene the number OpenGL calls is almost half and the fps diff is ~370 vs 340.

This means that you cannot render the primitive correctly when applying the world transform to the local position in a shader for example: ```glsl // 1. the position attribute is in local space (i.e pixel local coordinate space) gl_Position = view_proj * mtx_world * vec4(position.xyz, 1.0); // 2. the position attribute is in world space gl_Position = view_proj * vec4(position.xyz, 1.0); ``` These two statements should produce identical results, but doesn’t since the size is applied to the world transform for both sprites and particles. This has now been fixed, which means that we can use custom vertex formats to properly do billboarding properly. **FIX** : ([#11919](https://github.com/defold/defold/pull/11919)) **‘Fix for positions in local coordinate space for particles’** by Jhonnyg The transform was previously applied to the local space positions, which caused the particle system to produce rotated vertices in to the vertex buffer. **FIX** : ([#12052](https://github.com/defold/defold/pull/12073)) **‘Cache the viewport rectangle to avoid potential performance issues on the HTML5 platform’** by AGulev Cache the viewport rectangle to avoid unnecessary OpenGL calls.

We now only call this method for symlinks to stateless resources, where the existence of the file is important to determine at read-time. This change resulted in a 24% project load time improvement in the large project we were testing in, but it will vary depending on the project. **FIX** : ([#11923](https://github.com/defold/defold/pull/12065)) **‘Editor fix: Allow shaders to compile with page count \> 8’** by JosephFerano Allow the compilation of shaders when a paged material exceeds the maximum allowed pages currently set to 8 when “Exclude GLES 2.0” is not checked in game.project \> Shader setting. **FIX** : ([#11976](https://github.com/defold/defold/pull/12018)) **‘Fix broken handling of shader compiler warnings in the editor’** by matgis Fix unhelpful error during editor builds when the GLSL shader compiler emits warnings. **FIX** : ([#11985](https://github.com/defold/defold/pull/12024)) **‘Eliminate unnecessary code editor redraws’** by matgis - Fixed an issue where the code editor would redraw unnecessarily when moving the mouse cursor across the view. - Fixed an issue where the blinking cursor could cause the code editor height to oscillate by half a pixel when placed on the first row of a file. ## Other **FIX** : ([extender#385](https://github.com/defold/defold/pull/11950)) **‘Up Android min sdk version to 21 (Android 5.0)’** by ekharkunov ⚠ The minimum supported Android API version has been increased from 19 (Android 4.4) to 21 (Android 5.0).
