Version 1.2.1 (Dec 2017)

Updates:

• Opens the event framework so developers can add their own custom events.
• Opens WorkbenchViewController so developers can add their own UI states.
• Adds keepTrashedBlocks to the workbench, which controls if users can open
  the trash folder. By default, it is set to false (matching default Web
  behavior).
• Removes use of deprecated characters property on Strings.
• Changes the workbench to allow changing the viewport location based on
  workspace location, and sets it to first open at the top-leading corner of the
  workspace.
• Fixes FieldCheckbox to serialize XML into capitalized values, matching Web
  behavior.
• Fixes turtle demo so it stops highlighting/scrolling blocks into view
  if the user has edited the workspace.
• Updates i18n messages and compiled version of Web Blockly to latest
  November 2017 release.

Version 1.2 (Oct 2017)

Additions:

• The UI now respects the iOS 11 "safe area" so that all visible content and
  touch areas are displayed within the safe area. Currently, this only affects
  apps running on iPhone X, since its defined safe area doesn't fully conform
  to its screen dimensions.
• Adds method to WorkspaceView, to set the viewport to a reveal a specific
  location.

Updates:

• Changes LayoutFactory to be a class instead of a protocol.
• Removes DefaultLayoutFactory and refactors its functionality into
  LayoutFactory.
• Fixes "if-return" block to automatically disable itself if it isn't connected
  to a procedure definition block.
• Fixes Turtle demo so it is zoomable and so it no longer allows the turtle to
  run off-screen.
• Fixes bug in RTL where zooming caused the viewport to jump to a different
  location.
• Fixes bug in RTL where dragging the first block onto an empty canvas caused
  the block to temporarily flash at a different location.
• Fixes WorkspaceView from adding extra canvas padding to an empty workspace.

Version 1.1.3 (Oct 2017)

Updates:

• Updates the library to use Swift 4 syntax. This requires that developers
  update to use Xcode 9.
• Adds flipRtl property to FieldImage, allowing images to be flipped in RTL
  rendering
• Updates i18n messages and compiled version of Web Blockly to latest October
  release.

Fixes:

• Fixes bug where cancelled touches weren't being handled inside
  WorkbenchViewController, which caused state problems
• Fixes bug where popovers could be overdismissed

Version 1.1.2 (Sep 2017)

Updates:

• Allows disabled blocks to be dragged on the workspace
• Adds serialization for Block properties editable, deletable, movable, disabled,
  and inputsInline

Fixes:

• Fixes code generator for iOS 11 so it sends the initial codegen request on the
  main thread
• Fixes names of two codelab sounds
• Fixes bug where popover delegates were being overriden, which caused undo/redo
  buttons to stay disabled after popover dismissal
• Fixes bug where non-top-level variables didn't always show up in the variable
  drop-down picker
• Fixes FieldLayout from implicitly updating the layout tree on model changes,
  and made it update explicitly.
• Fixes ViewBuilder bug where it would recycle views prior to calling a delegate
  method that inspected view hierarchy
• Fixes WorkspaceViewController bug where the didRemoveBlockView() delegate method
  wasn't being fired
• Fixes bug where the same variable block can be created multiple times
• Fixes Obj-C compilation error where WebKit protocol can't be found

Version 1.1.1 (July 2017)

• Fixes bug where dismissing a popover could dismiss WorkbenchViewController.
• Fixes trash can folder so it always appear above the undo/redo controls.

Version 1.1 (July 2017)

This version packs our biggest UI update thus far! Many changes were made to make
Blockly iOS look and feel more modern. These changes include:

• Custom popovers for entering a number and for picking an angle
• A fresh coat of paint to the UI that uses Material Design colors
• Automatic vertical alignment of fields and inputs
• Rounded block corners
• More consistent sizing and spacing for all blocks
• Changing block dragging so that it appears above all other layers
• Better visibility when highlighting connections between blocks
• Improved style configuration. More style options have been added to
  LayoutConfig and DefaultLayoutConfig.
• Other minor UI fixes to improve usability

Version 1.0 (May 2017)

We're happy to announce that we've reached version 1.0 of Blockly iOS!

With this milestone, the project is at a point where all core components of Blockly
have been implemented on iOS. The API is relatively stable, and major performance
and memory issues from previous versions have been addressed.

Developers new to Blockly iOS should check out our
codelab.
It walks you through the process of creating an iOS app with Blockly.

Version 0.7.4 (Apr 2017)

• Updates Cocoapods podspec file to specify AEXML 4.1.0 to accomodate Swift 3.1.

Version 0.7.3 (Apr 2017)

• For both CodeGeneratorService#generateCode(forWorkspace:onCompletion:onError:) and
  CodeGeneratorService#generateCode(forWorkspaceXML:onCompletion:onError:),
  the callbacks for onCompletion and onError now include a requestUUID parameter.
• Updates Cocoapods podspec file to specify Swift 3.1.

Version 0.7.2 (Apr 2017)

• Adds workaround for whole-module-optimization compiler bug in Xcode 8.3/Swift 3.1.

Version 0.7.1 (Apr 2017)

• Fixes compile errors/warnings related to Swift 3.1 (when using Xcode 8.3+).

Version 0.7 (Apr 2017)

• Adds support for events and undo-redo functionality.

• The library is now localized to support all languages available in Blockly
  Web (except for those unsupported by iOS itself).

• Allows native "extensions" to be run on Block objects, upon instantiation.

• Mutators and extensions can now be defined inside JSON Block definitions.

• New LayoutConfig options for coloring field labels (FieldLabelTextColor and
  FieldEditableTextColor).

• Adds workspace:willAddBlock: and workspace:didRemoveBlock: to WorkspaceListener.

• IMPORTANT NOTE: WorkbenchViewController has been changed to expose a BlockFactory
  instance, via the blockFactory property. Clients should use this instance when
  creating new blocks inside the workbench, instead of using a separate instance.
  WorkbenchViewController needs to use this block factory when re-creating blocks
  or else it will not operate correctly (eg. for performing undo-redo actions).

Version 0.6 (Feb 2017)

• Adds variables and procedures
• Adds support for mutators (along with a default mutator for an if-else block)
• Changes Block and Field objects so that multiple listeners can listen for their changes
  instead of just a single delegate.

Version 0.5.1 (Nov 2016)

• Fixes bugs with the turtle demo.
• Fixes FieldInputView being uneditable in the iPhone 7/7+ simulator.
• Fixes jumping bug while zooming the WorkspaceView.
• Adds a DefaultLayoutConfig option for rendering a "start hat".
• Changes the CodeGeneratorServiceRequest flow. This is a breaking change, see
  https://developers.google.com/blockly/guides/configure/ios/code-generators for more information.

Version 0.5.0 (Oct 2016)

• Developer preview release of Blockly for iOS.
