# Release notes

## 2.1.1

* A small maintenance release that removes dist files from source control ([#676](https://github.com/regl-project/regl/pull/676)), upgrades headless-gl for dev ([#675](https://github.com/regl-project/regl/pull/675)), and adds missing TypeScript declarations ([#674](https://github.com/regl-project/regl/pull/674)). It should contain no changes to runtime execution.

## 1.6.1

* Browsers select their own, perhaps inconsistent, default for the `premultipledAlpha` context creation attribute. Regl enforces consistency by filling in unspecified values but since 1.4.0 has enforced `false` if unspecified, which seems to be nonstandard and in the minority. For improved backward compatibility, this PR sets `premultipledAlpha: true` when not explicitly specified. ([#566](https://github.com/regl-project/regl/pull/566), [#567](https://github.com/regl-project/regl/pull/567))

* Remove an additional ES6 keyword ([#564](https://github.com/regl-project/regl/pull/564))

## 1.5.1

* Remove accidental inclusion of ES6 keywords ([#562](https://github.com/regl-project/regl/pull/562))

## 1.5.0

* Resize canvas using ResizeObserver, if available. ([#556](https://github.com/regl-project/regl/pull/556))

* Fix several bugs related to `regl.frame` cancellation

## 0.9.0

## 0.8.0

* Optimize texture and cubemap constructors
* Add in place update method for textures via `texture.subimage`

* Pool stream buffers
* Rewrite resource section of API, bring individual resources to the top
* Optimized buffer and elements creation, no more memory allocation
* More test cases for textures

## 0.6.0

* Allow for dynamic properties in viewport, scissor box and attributes

* Switch order of arguments to dynamic functions, from (props, context) to (context, props)

  * functions without a props argument become batch static

* Implement non-batch constant context, framebuffer and viewport

* Batched scope rendering

* Switch order of props and context variables for dynamic function args

* function invocation now takes batch id as separate parameter

* Support directly constructing elements and attributes from arrays

* Allow individual attribute properties to be dynamic (eg buffers, offsets, etc.)

* Code generation rewrite

  * State flag polling is now inlined
  * draw and batch inlined for static shaders
  * constants are inlined
  * fewer arguments passed to generated code
  * Stop using separate arrays for stacks to manage state, instead state is saved onto the call stack

* Error reporting

  * All error messages should link to command/resource declaration
  * Improve validation of vertex attributes
  * Improve validation of dynamic properties

* Code quality and contributing

  * Combined lib/state.js and lib/compile.js into lib/core.js
  * Delete most of lib/attribute.js
  * Update development documentation

* Expose limits for shader precision

## 0.5.0

* Context variables

* Use `this` argument effectively

  * Should pass this to dynamic attributes and scope

* Make scopes and dynamic attributes take same argument

* Combine batchId with stats argument

* Pass `this` to draw commands so that they can be stored as members

## 0.4.0

* Circle CI finally passes!
* Use numeric ids instead of strings for shader sources
* Shader error messages are better
* Browserify transform to remove all runtime checks
* Shader linking is deferred until draw call, enables partial shaders in scope
* Report errors for missing attributes, uniforms and vertex count

* Fix attribute binding bug

## 0.1.0
