• Added panelset chunks that output code chunks source and results in separate panel tabs (#59)

• Added broadcast, a new experimental extension that allows viewers to follow the presenter's slides in their own browsers (thanks @spcanelon, #51, #58)

• Changing a panelset tab now emits a window resize event in hopes that any HTMLwidgets contained in the panel will resize to fit the panel container (thanks @mfherman #64)

New Features

• Panelset now works with the same markdown formatting as R Markdown's .tabset feature in R Markdown documents! See the panelset documentation for more information and examples (#41).

Bug Fixes

• Fixed an issue with URL updating and panelset that caused security warnings in Safari and led to temporarily broken slide navigation (thanks @jvcasillas, #50)

• Fixed several issues with style_share_again(): fixed default arguments, the buttons now correctly inherit the foreground color, and slides without an author or title are handled correctly (thanks @mattwarkentin, #48).

• Use absolute units for share bar sizes and fix a typo in share bar hover text (thanks @apreshill, #44)

New Features

• Added a new extension for sharing your slides called share again. It adds a "share bar" to the bottom of your slides when embedded in an <iframe> in another page. Another function embed_xaringan() is provided to embed slides in blogdown and R Markdown HTML sites in a responsive container.

Updates and Changes

• Various updates do use_logo() documentation. The class to hide the logo is .hide_logo and the logo CSS and JavaScript are embedded directly for xaringan >= 0.16 (thanks @chainsawriot, #22, #24, #25, #30)

• Updated cookie settings when storing editable fields (#42)

• Disabled spell check and auto complete in editable areas (#16)

Breaking Changes

• The CSS variables for panelset have been renamed and the arguments of style_panelset_tabs() haven been updated for ease of use. Unfortunately, this change is not backwards compatible; using the previous argument names will result in an informative warning without throwing an error. The panelset also does a better job of handling many tabs, which are now wrapped into multiple lines of tabs. (thanks @realauggieheschmeyer, #37, #38, #39).

• In conjunction with the item above, the style_panelset() has been renamed style_panelset_tabs(). This more clearly describes the part of the panelset that is styled, and it helps clarify the meaning of the more concise function argument names.

• Increased specificity of CSS rules for the panelset.

• Added --panel-tab-background-color with additional -active and -hover custom properties to style the background color of tabs. Similarly, two CSS variables for border color were added: --panel-tab-border-color-active and --panel-tab-border-color-hover.

• Updated Tachyons to 4.12.0 (#27)

• Added clipboard extra with use_clipboard(). Adds a "Copy Code" button to code chunks (<pre><code>...</code></pre>) and works in both xaringan slides and R Markdown documents (thanks @mattwrkentin #20, #36).
