3.4.8 -- 23 Mar 2016

BUGFIX:

* Safeguard against null fields in selections. See #530.

3.4.7 -- 19 Mar 2016

BUGFIX:

* Added custom CSS which allows plotly to work nicely in ioslides.

3.4.6 -- 17 Mar 2016

NEW FEATURES:

The 'plotly_relayout' event is now accessible via the event_data() function.

Fixed #514.

3.4.5 -- 17 Mar 2016

BUGFIX:

Fixed #514.

3.4.4 -- 17 Mar 2016

BUGFIX:

Show discrete positional values in tooltip (see #515); better GeomTile conversion; pass plot object into layers2traces.

3.4.3 -- 14 Mar 2016

BUGFIX:

Custom facet labeller functions will now translate correctly. See #507.

3.4.2 -- 14 Mar 2016

BUGFIX:

Automatic resizing will now occur only when layout.autosize is true (the default). See #403.

3.4.1 -- 13 Mar 2016

BUGFIX:

Legend titles are now supported.

3.4.0 -- 12 Mar 2016

NEW FEATURES:

* geom_map() and geom_hex() are now supported.

CHANGES:

* The default value of the fileopt argument was changed from "new" to "overwrite".

BUGFIX:

* Made a number of bugfixes/improvements to hoverinfo & conversion of geom_tile()/geom_point().

3.3.1 -- 10 Mar 2016

CHANGES:

* Changed the mapping argument name to tooltip (which seems like a better name).

BUGFIX:

* Redundant legend entries are no longer shown.

3.2.1 -- 10 Mar 2016

BUGFIX:

* Proper formatting for date tooltips.

3.2.0 -- 10 Mar 2016

CHANGES:

* Legend titles no longer appear in legend entries.
* Tooltips now reflect aesthetic mappings. This makes it easier to decode 
data values from a given visual marking.

NEW FEATURES:

* geom_violin() is now supported.
* ggplotly() gains a mapping argument to control the set of aesthetics to appears in the tooltip as well as their order.

3.1.0 -- 8 Mar 2016

CHANGES:

* The "hidden" sharing option in plotly_POST() was renamed to "secret".
* The default value in the scale argument in plotly_IMAGE() is now 1.

3.0.0 -- 8 Mar 2016

NEW FEATURES:

* ggplotly() is now about 20x faster (it avoids calling ggplot_build() 20+ times). In some cases, it might be even faster since a lot of other redundant computation is avoided.

CHANGES:

* Instead of (trying to) translate both major and minor grid lines, we now translate only major grid lines. This generally produces a result closer to the actual ggplot2 result since ggplot2 doesn't draw ticks on minor grid lines.

BUG FIXES:

* ggplotly() now supports most of scale_*()/theme()/guides(). As a result, this fixes a lot of issues (#482, #481, #479, #476, #473, #460, #456, #454, #453, #447, #443, #434, #422, #421, #399, #379, #378, #357, #318, #316, #242, #232, #211, #203, #185, #184, #161). In order to support all of scale_x_*() an scale_y_*(), we always use linear axis types, and supply ticktext/tickvals to plotly.js. This has some unfortunate consequences on hoverformatting, which may be addressed in future releases of plotly.js -- https://github.com/plotly/plotly.js/issues/320

2.5.0 -- 1 Mar 2016

NEW FEATURES

* New event_data() function provides easy access to plotly events in shiny.
For an example, see https://github.com/ropensci/plotly/tree/master/inst/examples/plotlyEvents

* plot_ly() and ggplotly() gain a source argument to differentiate between 
plotly events in shiny apps with multiple plots. ggplotly() also gains width 
and height arguments.

CHANGES

The arguments filename, fileopt, world_readable in ggplotly() were removed as
they should be provided to plotly_POST() instead.

1.0.0 -- 31 July 2015

A major reworking of package internals which includes a few backwards incompatible changes.

Major changes include:

(2) New print methods which make it easier to create, modify, and embed Plotly graphs.
(3) Added a `subplot()` function for putting several graphs on a single page.
(4) Added the `renderPlotly()` and `plotlyOutput()` functions for embedding plotly graphs in shiny applications.
(5) Added `offline()` function for creating standalone HTML pages via Plotly Offline (see http://purchasing.plot.ly/)
