Prepare Release 1.20.0

[cmslewis]

🎆 Highlights: Table batch cell rendering and other performance improvements

📖 Latest docs: blueprintjs.com/docs

@blueprintjs/core 1.20.0

• NEW Added four UI icons (Added new UI icons #1221)
  • Bank account, IP address, cell tower, ID number
    

@blueprintjs/datetime 1.17.0

• NEW TimePicker disabled prop ([DateTime] Add disabled prop to TimePicker #1219) (🎩 @AlexMarvelo)

@blueprintjs/table 1.17.0

• 🌟 NEW Table cells are now batch-rendered within each frame when scrolling ([Table] Batch Child Rendering #1201)
  • This yields much smoother scrolling, with the tradeoff of showing momentary flashes of white as rendering catches up.
  • This batching behavior is not yet user toggle-able or configurable, but will be in the future.
    
• NEW ColumnHeaderCell/RowHeaderCell index prop, which is passed to callbacks if provided ([Table] Introduce Cell/HeaderCell index props and pass them to callbacks #1210)
  • No more having to instantiate new anonymous callback functions when rendering either of these components; the index can be passed directly to a persistent callback function instance.
• NEW ColumnHeaderCell/RowHeaderCell renderMenu prop
  • renderMenu is an example of a callback that henceforth can be instantiated only once, because it receives the row/column index as a parameter.
  • menu is now deprecated in favor of renderMenu ([Table] Introduce HeaderCell#renderMenu prop, deprecate HeaderCell#menu prop #1218)
• NEW getShallowUnequalKeyValues and getDeepUnequalKeyValues utility functions ([Table] Add new utils: getShallowUnequalKeyValues and getDeepUnequalKeyValues #1222)
  • These functions streamline debugging of shouldComponentUpdate methods; they will thus be more useful for Blueprint contributors than for Blueprint consumers.
• Fixed Table componentWillReceiveProps now responds to more prop changes and updates the component accordingly ([Table] Add more checks to componentWillReceiveProps #1165)
• Fixed ColumnHeader/RowHeader shouldComponentUpdate issues ([Table] Fix shouldComponentUpdate issues in *Header's #1215) ([Table] Bugfix: Have column headers and row headers respond to FULL_TABLE selections too #1217)

@cmslewis build failed cuz site-docs has some invalid versions in package.json. gotta audit those and make sure they all line up with latest in each other package.json

[giladgray]

• list the new icons
• prefer to put ComponentName as first word in note: "NEW TimePicker disabled prop"
• add "(:tophat: @ AlexMarvelo)" to datetime note for external contrib
• we should add a GIF for the batching so folks know what to expect
• i don't put parens around issue numbers, but i kinda like it 🤷‍♂️

[adidahiya]

• datetime 1.17, not 0.17

[cmslewis]

@giladgray the parens around issue/PR numbers come from my copy-pasting the commit descriptions directly into the PR description. I could take them or leave them.

[waterscaleb]

I am using the blueprints/Table in a GoldenLayout container and having issues trying to render new cells on container events. Is there plans to have a hook for batch rendering?

[tgreenwatts]

Hi @waterscaleb - I moved your question into a separate ticket here #1317. This PR is closed and not relevant

We've got a lot of vacations right now, so we'll probably respond next week. Thanks!
