Version 0.13.1

Minor Breaking Changes

Wait, what? Breaking changes in a patch release?
Yes, but it's really small and GitHub code search didn't show a single use of it out in the wild.

• RecyclerConfiguration is no longer part of RecyclerCollectionComponentSpec but a top-level class. f2b00a8
• Don't override child layout params by @vinc3m1 (#328)

Version 0.13.0

Breaking changes:

• TextSpec bounds are clipped by default.

What's new:

• Introducing Error Boundaries similar to React which helps to handle errors in lifecycle methods gracefully.
• Added EventHandler support in TestSpecs.
• Added StateValueAssert to be able to assert StateValues without unwrapping them.
• Added support for specifying custom ViewTypes when using ViewRenderInfo.
• Added rotation prop to Components (mainly used for animating rotation with Transition API).

Improvements/Fixes:

• Fixed StartSnapHelper when child views are smaller than half the size of the RecyclerView.

Version 0.12.0

Breaking changes:

• StateUpdatesTestHelper has now its own testing.state package.
• RowReverse and ColumnReverse got removed. Row and Column offer a reverse() property setter to achieve the same.
• Stetho support, as already announced in v0.11.0, was removed.
• Last but not least, onCreateLayout() now returns a Component and not a ComponentLayout!!
  buildWithLayout() is also gone.

What's new:

• Litho now supports StateListAnimator.
• Trigger APIs is now supported in Sections.
• New LithoTooltip APIs to show a PopoverWindow.

Improvements/Fixes:

• EditTextSpec accept now a TextView.OnEditorActionListener.
• The corner effect for the border got fixes and we also improved the border radii APIs.
• TextDrawable Span click detection got fixed for multi-line Spans.
• HorisontalScrollSpec now supports RTL.

Version v0.11.0

TestSpecs

TestSpecs offer a new way to test your components. Check out the post in our Facebook group or jump straight into the docs.

So long, Stetho, and thanks for all the fish

v0.11.0 is the last release of Litho that comes with Stetho support. We are removing the integration with the next release (v0.12.0). We are really sorry for the inconvenience that we know this will cause some people but we think that it will be good for the future as it allows us to move faster and provide a better debugging experience down the line. We have nothing to announce in that regard just yet.

Version 0.10.0

What? Another release already? Yes, and there have been some interesting changes.

Breaking changes

Layout was renamed to Wrapper: 38837d7

The new API is more Component-y and takes your delegate as a prop rather as part of the constructor call. Instead of writing Layout.create(c, component), you now write Wrapper.create(c).delegate(component). @IanChilds wrote a handy codemod script to help you with the transition. You can use it like this: git grep "import com.facebook.litho.Layout;" -l | xargs -L1 python WrapperForLayout.py.

• Performance improvements through pooling adjustments (cdb10be, c33039f, a6821e1, 8dd2abb, 364bf84).
