# Release notes

## 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))

## 1.5.0

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

## 1.4.0

* Add vertex array objects via regl.vao

## 1.3.0

## 1.2.1

* Fixed bug with depth and stencil attachments being cleared
* `regl.elements` now correctly infers count from length and vice-versa

## 1.2.0

## 1.0.0

* Support `stencil.op`
* Rename stencil op `pass` to `zpass`

* Add `regl.now()`, allows sampling timer at high resolution outside of `regl.frame` in order to better synchronize DOM events

## 0.11.0

* Can now use framebuffers as textures in uniforms.  By default color attachment 0 is used.
* Support for dynamic properties with nested objects like attributes
* Alias `float16` for `half float` and `float32` for `float`
* Many bug fixes and stability improvements
* Website mostly works (preview at [regl.party](http://regl.party))

## 0.10.0

* Add a mechanism for managing webgl extensions

  * Should be able to report errors when extensions are missing
  * Allow users to disable extensions for testing/mocking

* Doc clean up

* Add more test cases for `regl.read()` and improve validation

* Implement a standard method for handling context creation errors

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

## 0.9.0

## 0.8.0

* Optimize texture and cubemap constructors

* 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

## 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
