Features:
* polymorphic sprite-local custom blocks
* inheritance of sprite-local custom blocks
* localization support when typing expressions
* support for user-forced line-breaks in custom block labels
* ternary Boolean slot setting: support to limit Boolean input slots to
“true/false” outside of rings and in palette
* support for default values in custom block Boolean slots
* experimental: duplicate block definition (hidden in shift-click
context menu)
* support for codification of String, Number and Boolean value types
* costume icons indicate svg costumes
* sprites’s rotation centers can be adjusted onstage
Fixes:
* changed keyboard shortcut indicator for “find blocks” to “^”
* prevent Snap from “hanging” when encountering certain errors in
visible stepping
* only mark implicit parameters if no formal ones exist
and from causing an error because they can’t be.
Also, changed wording of variable renaming menu items
and added a shadow to the variable block symbol in the dialog box (so
it looks the same as the one that’s already in use elsewhere)
* improve keyboard navigation (use right-/left-arrows to enter/leave)
* delay popping up submenus when mousing over submenu items
* right-align submenu indicator (same as a shortcut)
* keep submenus open if the mouse leaves them
* support creating custom drop-downs from nested dictionaries
* auto-wrapping for C-shaped slots (around top-level command stacks)
* settings option for auto-wrapping around inner nested stacks
* unlimited “undrop / redrop”, incl. keyboard shortcuts ctrl-z
ctrl-shift-z
* “undrop” also brings back blocks and scripts deleted via context menus
* … or via backspace / delete in keyboard entry mode
* Note: “undrop” is meant to be a temporary solution until
VanderbiltEdu’s synching / undo mechanism is ready for prime time
* Visible Stepping with flashing blocks + slider for stepping speed
* user-controlled visible stepping with “step forward” button
* speed-up: removed unnecessary yields when running custom blocks
* you can now force a single yield with “wait 0” block
* tweaked keyboard entry: if inserted block has inputs go to first one
* only autoscroll panes where it makes sense (not the palette etc.)
* populate messages drop-down with all msgs, including ones from custom
block definition
