htmlwidgets 1.5
-----------------------------------------------------------------------

* Fixed an incompatibility with Shiny v1.4.0: due to Shiny upgrading
  from jQuery 1.x to 3.x, the timing of some initialization routines
  has changed. This caused some widget `renderValue` calls to occur at
  an earlier point in Shiny's initialization process than with earlier
  versions of Shiny. (#345)


htmlwidgets 1.4 (unreleased)
-----------------------------------------------------------------------

* JavaScript statements can now be passed along to `onRender()` and
  `JS()` (#329).


htmlwidgets 1.3
-----------------------------------------------------------------------

* All files and directories under the `inst/htmlwidgets/` directory of
  a widget package will be copied when a widget is rendered due to an
  unintended change in #306. Only the single `WIDGET.js` file should be
  copied (where `WIDGET` is the widget name). Fixed via #312.

* Support for async Shiny. Widget render functions that use the default
  implementation of `htmlwidgets::shinyRenderWidget` can receive
  promises of widget objects (you can, of course, continue to use
  regular widget objects as well).

  See https://rstudio.github.io/promises for more about async Shiny.


htmlwidgets 1.2
-----------------------------------------------------------------------

* htmlwidgets can be created without a package, without yaml, and/or
  without JavaScript binding. (#304, #305)

* Use RStudio Page Viewer for full page widgets.

* Fix #297: Setting background in saveWidget() is broken


htmlwidgets 1.1
-----------------------------------------------------------------------

* The saveWidget's background parameter could not process hex color
  codes, due to changes introduced in htmlwidgets 1.0. (#297)


htmlwidgets 1.0
-----------------------------------------------------------------------

* Fix issues with self-contained mode when used with new versions of
  pandoc. (#289)


htmlwidgets 0.9
-----------------------------------------------------------------------

* Starting with R 3.4.0, a "Calling 'structure(NULL, *)' is deprecated"
  warning would occur when shinyRenderWidget encountered a NULL value.
  (#269)

* Fix edge case where using dynamic HTML dependencies from a widget
  binding's JS factory function would fail.


htmlwidgets 0.8
-----------------------------------------------------------------------

* Export getDependency function

* `onRender` hooks were firing too early when used in Shiny apps.

* Widget IDs: only restore random.seed when non-NULL


htmlwidgets 0.7
-----------------------------------------------------------------------

* Pass knitr options to saveWidget

* Ensure that scaffoldWidget opens files correctly within RStudio

* The resize handler also works for the JavaScript events `shown.bs.collapse`
  and `hidden.bs.collapse` now so that widgets inside the Bootstrap collapse
  class can be displayed

* Fix references to vignettes in documentation

* Add elementId parameter to widget function generated by scaffoldWidget

* More robust method of generating unique widget IDs

* Modify advanced and sizing vignettes to use new style widget declarations


htmlwidgets 0.6
-----------------------------------------------------------------------

* Introduce new scheme for defining JavaScript bindings that will make
  it easier for widgets to gain access to other widget instances on
  the page.

* Add `onRender` hook for widgets to execute custom JavaScript code
  after rendering.

* Add `appendContent` and `prependContent` functions for adding HTML
  to a widget rendered in a static context (i.e. R console or Rmd)

* Fix a bug where the string "</body></html>" in the widget data caused
  `saveWidget()` to have malformed output. (#168)

* Tweak pandoc conversion used in saveWidget to prevent hanging with
  large htmlwidget script data elements (use "markdown" rather than
  "markdown-strict" as input format)

* Increase pandoc stack size to 512M for saveWidget (often required for
  e.g. larger embedded leaflet maps). Stack size can also be controlled
  by the pandoc.stack.size option.

* Import latest version of with_pandoc_safe_environment from rmarkdown

* Fix issue that prevented calling renderValue() from within resize()


htmlwidgets 0.5
-----------------------------------------------------------------------

* Add background parameter to saveWidget function

* Fix a bug where "</script>" appearing in widget data would break
  parsing

* Fix a bug where multiple widgets on a page caused all but one to miss
  resize events

* Sync vignettes with contents of htmlwidgets website


htmlwidgets 0.4
-----------------------------------------------------------------------

* Use minified files while scaffolding widget wherever available

* Suppress viewing widgets in non-interactive R sessions by default

* Export the HTMLWidgets.staticRender function

* Add a preRenderHook for widgets

* Use jsonlite rather than RJSONIO for JSON serialization

* Call widget.resize in more situations
