• New Features:
  • lists as dictionaries: alphanumeric indices for lists, access fields (JSON) and columns (CSV) by name
  • include custom block data dependencies in libraries, eliminates the need for initialization routines creating and populating variables required by custom block definitions
  • visually highlight variable scope when mouse-hovering over a variable declaration in visible stepping mode
  • visually highlight the variable declaration of variable accessor blocks when mouse-hovering over them in visible stepping mode
  • visually highlight senders / receivers when mouse-hovering over messaging blocks in visible stepping mode
  • show intermediate results when debugging a script, i.e. when clicking on a script in visible stepping mode. Thanks, Vic!
  • new "When (sprite) is edited" event hat block, supports light user interaction logging
  • new PIPE primitive in the control category
  • "touching" predicate now also accepts a 2-item list representing x/y-coordinates to check for collision with an arbitrary point
  • hyper-rays: support lists of relative angles in the left "ray length TO sprite" input slot for instant fields of vision
  • added "delete" option to context menu of global and sprite-local variable declarations in the blocks palette
  • added "translations" selector to metaprogramming blocks
  • new "disable dragging data" preference setting for (kids') MicroWorld creators
  • pixels library: Added command blocks to rename and export costumes
  • new "ide_blocks" extension primitive
  • new extension primitives: "txt_to_utf8(txt)" and "txt_from_utf8(utf8List)", thanks, John!
  • new extension primitive "txt_transform(name, txt)" for encoding, decoding, escaping, unescaping and hashing text
  • new extension primitive "cst_export(cst, name)" for exporting/downloading a costume
  • new extension primitive: "syn_scripts([xml])" for getting & setting (and deleting!) the scripts of a sprite
  • codification: calling "code of" on a sprite returns a text version of its scripting area (concatenated codified scripts delimited by empty lines)
  • extensions can auto-load and auto-exec allowed or allow-listed external JS scripts that modify the IDE, e.g. to add buttons by storing the external url in global (optionally hidden) variables whose name starts with "module"
  • extensions can add custom buttons to the palette, thanks, Bernat!
  • added retina support for inlined morphic worlds, enabling high-res embedding of Snap! components into other websites
  • added configuration options for embedding Snap! into other websites
  • new API methods for synchronizing scripts across sprites and Snap! instances
  • new API methods for signalling scripts through highlighting blocks that correspond to marked portions of mapped text code
• Notable Changes:
  • enabled same-named global and sprite-local variables
  • no more error messages when the number of actual arguments doesn't match the number of implicit parameters
  • removed empty parens from extension prims "ide_all_blocks", "ide_language" and "ide_translations"
  • hyperized bitwise operators, and gave them more mnemonic block names, thanks, Bernat and Brian!
  • optional inputs "broadcast" and "switch to scene" blocks don't auto-fill when called with an input list
  • made formal parameters available in variable-menu dropdowns of all blocks inside of block editors
  • hyperized "code of" reporter (codification primitive)
  • round watcher readouts to 6 decimal digits (like Scratch), instead of 9
  • updated "for each" help screen, thanks, Brian!
  • TuneScope extension update, thanks, Harsh, Jo and Glen!
  • SciSnap2 extension update, thanks, Eckart!
  • MQTT library update, thanks, Simon!
  • removed PIPE from all libraries (b/c it is now a built-in primitive in the control blocks palette)
  • updated "Codification" example project
  • hide "stage selected - no motion primitives" text when hiding the category names in single palette mode
  • order "my scripts" list by their top-down position in the scripting area (not by the time of their placement)
  • don't show "result pic" option in block context menu with "click-to-run" disabled
  • enable JavaScript extensions when running Snap! locally without a webserver (location.protocoll "file:")
  • enable "JavaScript function" primitive to be hidden / shown independently from enabling JavaScript extensions
  • shrunk some new built-in costumes, to make them load faster
• Notable Fixes:
  • fixed refactoring (renaming) variables (I hope, haha!)
  • fixed retaining transience when renaming a global or sprite-local variable
  • fixed displaying message senders
  • improved text wrapping - wrap words that are too wide for a line by letters
  • improved touch-hold gesture on mobile Android devices, thanks, @ego-lay-atman-bay!
  • don't show block relabel options that are marked as hidden
  • fixed aggressive cache issue, thanks, Michael!
  • fixed exporting pics of morphs in dev mode, thanks, @xBZZZZ!
  • fixed API->broadcast() to also accept a data payload, thanks, Zak!
  • SciScnap2 library: fixed SQL queries containing the percent characters
  • fixed exporting information about blocks in custom categories when creating a summary document (#3097)
  • fixed occasional "reporter did not report" error when changing a custom command block to become a reporter
  • fixed a naming issue when importing duplicate data files
  • fixed occasional errors when using "broadcast" and "this script" in the same script
  • fixed deselecting / selecting blocks in the "Unused Blocks" dialog
  • fixed "obj_name" extension prim to also accept numbers as names
  • fixed "Make Variables" extension for numerical names
  • fixed palette category ghosting update when hiding / unhiding blocks using extension primitives
  • fixed accidentally drawing unwanted dots when changing a pen color dimension thanks, Joan!
  • fixed zebra coloring for polyadic read-only input slots
  • fixed a label rendering glitch when flashing blocks
  • prevented variables from being renamed to blanks
  • caught an occasional maximimum call-stack size range error when embedding blocks into a scripts pic
  • improved frame scheduling, prevent excessive frame drops, thanks, SArpnt!
