v412


a bunch of fixes that prevent exceptions

v401


No longer requiring the shift key to access extensions.

v374


Improved detection of whether we can talk to Javascript without causing exceptions.
Added support for initializing the player via flashvars without javascript communication (including passing in the cloud token).
Fixed embedded player for IE.
Fixed js object formatting for logged in / anon page loads.

v367


added a hook to the SWF for downloading the current project to the local computer

v366


close tips when entering presentation mode

v360


dialog boxes are now centered both vertically and horizontally
the top bar and border is slightly darker to help it stand out

v356


Now trimming whitespace from the beginning and end of new variable names.
No longer allowing duplicate costume or backdrop names.
Fixed issues with variables and lists that have the same name.

v355


Fixed a costume renaming bug

v352


added Donegal font to paint editor

v349


use the new, larger default size only for newly created text elements
record the font size in the new SVG element (that wasn't being done before)
use the original default size if there's no size specified in the SVG element (that provides backwards compatibility)

v346


fix a bug Sarah found and the menu placement issue Tian reported
add a colon to the monitors for sprite variables (e.g. "cat: hunger level")
fix a few translation issues
remove (for now) a few of the new fonts from the menu until we make a definite decision (because we shouldn't remove a font once it has been deployed)

v345

The paint editor now supports multiple fonts. Currently, only embedded fonts are supported (as was the case before), so you can only use the "Roman"/Western European character set. There are plans to add a universal font later.
v344


Immediately save newly created projects

v342


Sprite/Backdrop/Costume library is now cached by SWF so it loads really fast after the first time.
make default duration of drum and rest blocks be 0.25
add note numbers to the note menu

v341


Fixes the gradient issue that Sarah found

v338


Moving a path that's being edited should work now

v335


Attempts to address general problem that the user does something in the project editor that triggers a save before the project has finished loading.
Bug 1082 is also fixed, but that's difficult to verify until this SWF is deployed because the project in question (10653182) is not visible on jiggler.
This SWF also includes a few paint editor tweaks from Shane.

v334


Fix a bug with blanking out costumes.

v333

Editor


bug 563: BIG ONE! total asset size limit: Scratch does not allow adding assets to a project if that would result in the project having over 50MB. To test, trying importing a bunch of long sounds to get close to the limit. Then try importing sprites, costumes, backdrops, sounds from library, disk, and backpack. It should give you a warning.
bug 551: All dialog boxes now appear centered near the top of the screen
bug 1065: Rollover for "Remix" button
bug 1063: When say/think bubbles interrupt each other, the last one determines how long the bubble stays up
bug fix: a NaN costume index prevented project loading
record SWF version in project metadata
improved internal support for extensions (nothing to see or test yet)

Paint editor


bug 836: added "Import" button
bug 1006: smallest brush now snaps to the normal-size pixel grid (not subpixels) to make it easier to work at the pixel level
fixed snapping of selection rectangle to the pixel grid when selecting; moving the selection still does not snap to the pixel grid (tried to fix that but its tricky)
Very rudimentary text wrapping for 1.4 text fields. This needs more work and will never work properly without the same font...
Made the tool cursors not show on scrollbars
Now showing a tooltip for the entira rea used for stroke/eraser widths.
Fixed event handling for tooltips on parental display objects.
New rotate cursor fmor Natalie. Fixed the "rotate bug" where the selection box was offset fmor the selection.
Fixed adding path points to a solid (unstorked) shape.
Added tooltips to the eraser/stroke width slider. (http://scratchexp.media.mit.edu/issues/1048)
Made the shutdown method safer to fix http://scrachexp.media.mit.edu/issues/335.
New resize, rotate, and move cursors.
Now allowing the use of built-in cursors for tools.
Improved radial gradients for rectangles. No longer using a focal point so that it works more like Scratch 1.4.
Fixed the export of zero=opacity stop colors in gradients.

v328


fix for lost project problem
first pass at gradients in the vector editor (from Shane)
added support for radial gradient focal points (from Shane)
in bitmap editor, pen and eraser sizes can now be much larger (uses Scratch 1.4 sizes)
in bitmap editor, eraser size shown as hollow circle
in bitmap editor, minimum brush size larger to avoid lines two thin to show on the stage
record pixels/inch of double-resolution bitmaps in exported PNG's
fetch assets from cdn to save server load
increase auto-save interval to 120 seconds (at Sayamindu's request)
bug 960: don't add multiple items on double click unless shift key
*ressed
bug ???: empty costume bug
make greenflag/stop available via JS (for Shane)
add "hasCloudData" flag to project info (for Glen)
Vector gradients have been implemented.

v324

This fix will make the SWF more robust in the face of server and network problems and high-load situations. For example, a few weeks ago, it would have prevented the (temporarily) lost projects when a deploy glitch broke project loading for a short period.
v321


cloud data changes from Sayamindu
bug fix: deleting a sprite causes global variable montiors to hide
bug fix: importing animated GIF gets stuck on "uploading" and costumes never appear
bug fix: variable menu showing generic block command ("duplicate", etc.)

v318

Found and fixed a bug in the project fetch "cache buster".
v317

This fixes the paint editor bug Mark found:

Paint Editor (Bitmap)
Probably an old bug - Load a background from the media library - then draw on it with the paint brush (just one stroke) - then try to undo the brush stroke.  The result is that the background image shrinks by maybe a factor of two.

v316


menu for note block
use cache buster for project fetching (attempted fix for the lost project changes issue)
can now import animated GIF as sprites, costumes, or backdrops
top bar grow/shrink tools now work on the entire contents of bitmap editor
tweaks for embedded editor (green-flag overlay, put website link in blue box)
fix bug importing Scratch 2.0 sprites with heading of zero
set project title on website when importing a project from disk and remixing
make default instrument "piano" (not electric piano)
remove several JS entry points that are no longer used
cloud data changes from Saymindu
paint editor fixes from Shane

v312

The bitmap editor paint bucket now supports gradient fills:

buttons for solid fill or 3 types of gradient
buttons reflect currently selected colors as preview of gradient
(the rectangle and ellipse buttons now also show the current color)
cool trick #1: when filling with the paint bucked, clicking multiple times in the same place fills a wider and wider range of colors (i.e. increases the color match tolerance). This was Shane's idea, I just improved the implementation. Wish we'd had this in 1.4.
cool trick #2: you can fill with a gradient between transparent and a color
gradient fill buttons currently hidden in SVG editor; Shane will add gradient support to the SVG editor when the website demands let up a bit.

Other:

added support for embedding the editor on code.org (or other websites). test url: http://web.media.mit.edu/~jmaloney/iframeEditorTest.html
fixed a problem with downloading Scratch 1.4 projects uploaded since launch (as opposed to projects migrated from the old website). To test, upload and share a project from Scratch 1.4, then use the "Download code" button under "Share to" to download it. It should download as a file (NOT display junk in your browser), but this won't work until we deploy.
added a microphone volume slider to the sound editor. This was needed by the Chromebooks because they don't have an OS control panel for changing the microphone level.

v314

v301


fix SVG rendering of an obscure form of "m" commands (PirateScratcCat now renders correctly - Arrr!)
added guide lines to paint editor to show costume center (Mitchel's request)
bug: long sprite names overlapping in backpack
bug 865: selected costume should be updated after reordering via drag-drop
bug 881: don't show "duplicate" in backpack item menu
revert to using our own server (not Fastly) to fetch project assets

v300


bug: backdrop category list is wrong (it's using the 'sounds' categories)
set sprite thumbnail when dragging sprite from library
fixed bug in reporting URL for old format projects
fetch assets from CDN/Fastly cache
make sure old costumes (and imported bitmap costumes) open in bitmap mode
bug 478: drag from backpack into paint editor
bug 760: shift + pencil on vector buggy --recommend removing Shift functionality for pencil
bug 835: dragging from Backpack in bitmap mode overwrites instead of adding
bug 851: svg costumes dragged into bitmap mode from backpack give error
bug #871: backdrop library is showing Sound library categories not backdrop categories

v299

Fixes the ability to insert images into the paint editor by dragging from the backpack, costumes list, and sprite library. In fact, it's now better than it's ever been. The key new features:

You can now insert images into the paint editor by dragging in another costume from the costume list or a sprite from the sprite library, as well as costumes or sprites from the backpack. When you drag in a sprite, it inserts the current costume of that sprite.
You can now insert images in bitmap mode, which didn't work at all before. The inserted image is selected and can be moved, rotated or scaled, before it is "baked in" to the bitmap layer. (Or you can delete the selection if you decide you don't want it.)

v298


remove code to save generic thumbnail for newly-created project (the server now supplies a good default thumbnail)
don't request the non-existent en.po file for English
the SWF now reports the URL for Scratch 1.x projects to support downloading them
bug 456: deleting a costume or backdrop from the backpack in the editor will also delete it from the project
bug 864: don't scroll palette to top when deleting a block or renaming a variable or list

v297


don't show save dialog unless assets have changed (i.e. not for script changes)
bug 700: need to optimize scrolling for user experience in editor (see also 643)
bug 606: leaving sound editor tab should stop sound playback in sound editor
bug 813: text color not changing (vector and bitmap)
bug 832: close Tips window when opening Media Library dialog
bug 843: need to save costume state before Converting
bug 844: flip button is not triggering a save costume

v295

Reverted an attempt to fix an bug involving sliders on watchers in a rare case which broke the common case. The cure was worse than the disease...
v294

Adds tooltips for all the new buttons:

New backdrop (under stage)
New sprite (under stage)
New backdrop (Backdrops tab)
New costume (Costumes tab)
New sound (Sounds tab)

v293


bug 184: invisible pixels blocking a Slider
new bug (reported by Boltbait via Fran; also found by Mark): some old projects with comments fail to load

v292


revert autosave interval to 1 minute
bug 532: don't redirect to project page when "share" button pressed in editor (test)
bug 545: Sprite "Can Drag in Player" checkbox incorrectly showing as checked
bug 629: "set size" block displaying multiple decimal points
bug 701: sort variables/lists alphabetically in palette
bug 798: prevent projects from not having thumbnails and showing the old censored cat talking image
bug 685: Scratch 1.x projects with a lot of sound data seem slow to download

v291


remember video transparency in project
drop comment on block to connect
import comment connections from old Scratch projects
bug: vector backdrops are offset if a vector element sticks over the edge
bug: list blocks change to variable color on project save/open
bug: "stop other scripts" block becomes final on project save/open or copy
bug:show local var/list should do nothing for a clone
shift-click Edit menu allows enabling SensorBoard/WeDo blocks
bug: set "dirty bit" when sound is edited
bug: MP3 progress indicator sometimes goes past end
bug 273: clear the play button overlay after receiving input like keypresses (test on Fireworks)
add Sprite x-y readouts under sprite watermark in scripting area
bug: costume disappears if costumes switched when text tool open
bug: costume center change lost if costumes switched when center tool open

v288

The important change is to reduce the autosave interval to a mere 10 seconds. This will help us stress-test the server's autosave mechanism. Before launch, the autosave interval will be increased to it's previous 120 seconds.
I also changed how thumbnails are fetched in the sprite/costume/backdrop library dialogs. They are now fetched more incrementally, allowing you to interact with the editor during fetching. This should help a lot when running on slow networks.
v287


bitmap paint bucket tooltip: Fill with color
vector paint bucket tooltip: Fill a shape
move stamp tool into tool palettes
move video blocks to sensing
don't have stop turn off the video
remove WeDo/SensorBoard extensions from menu
login -> sign in
broadcast dialog title: "New Message"
bug: trigger hat blocks not working in editor
remove "a" in new block dialog ("Add a number input")
remove rollover for palette switcher
eyedropper tooltip: "Pick up color"
vector paint bucket tooltip: "color a shape"
remove "hollow/filled" tooltips
bitmap stamp tooltip" "select and duplicate"
remove command key shortcuts from sound menu
make hat blocks have a min size (fix green flag hat in Arabic)
add tooltips for top bar tools (delete, duplicate, grow, shrink, block help)
include colons in strings to be translated such as "New sprite:"
add "show" checkbox to sprite info
translate labels for backpack items: Sprite, Costume, Backdrop, Sound, Script
video on -> "show video"
translate dialog for var max/min settings dialog
remember state of "show video" and, in player, turn on video automatically if set

v286

This push is entirely about translation. In particular, it attempts to ensure that:

every UI string is exported to the set of strings we put on Pootle for translators to translate
every UI string goes through the translation mechanism

I found and fixed many omissions including:

sound editor - edit menu
top bar - File and Edit menus
tab names
sprite info
camera
media lib
make var, list, block
right click menus
dialog box buttons
paint editor tooltips

v285

fixes the "toxic sprite from backpack" problem found by Lucario621 and reported by Mark
v284


bug: talk bubble can be messed up if sprite is dropped off the stage (the sprite returned to it's original location, the bubble didn't)
bug: talk bubble offset when dragging a sprite
paint editor: keep the shape tool (rectangle, ellipse) selected while placing the shape

v283


bug: scripts saved in right-to-left language were being saved with argument in incorrect order (glad I found that one!)
bug: the scripts of loaded or remixed projects were not getting translated
reload project page if language was changed inside the editor (so project page is shown in the new language)

v282

Big changes:

reworked all block menus (and block parameters with menus) to better handle translation
reworked handling of right-to-left languages to correctly handle basic math ops (+, -, *, /, %) (Only Arabic evaluates math operations right-to-left; Hebrew and Farsi evaluate left-to-right.)

Other changes:

bug fix: boolean parameter reporters were turning into normal reporters after project save/open
bug fix: theme and image type selectors were not showing for costume library
normalize block menus (put generic commands at top, not bottom)
mechanism for translation of block arguments controlled the associated menu

v281


A new "video on" checkbox appears below the new backdrop buttons the first time you drag out a video sensor block or select "video motion" from a trigger hat block. Video will be turned on (if a camera is available) when this checkbox first appears. After that, video is no longer turned on automatically by the video sensor block or video motion trigger hat. Video can be turned on or off using either the checkbox or command blocks. This gives users more control over when the video is turned on (e.g. the video motion trigger block no longer keeps turning the video back on after the user turns it off).
Added a new "turn video on" block to Sensing category (to make it easier for people to discover how to turn on the video when using the video sensor block).
Talk bubbles now placed closer to sprite. (Note: this uses a heuristic similar to that used in Scratch 1.4 that assumes that anything that sticks up from from the top of the sprite is the character's head. That doesn't work for all characters and it doesn't work if the character is upside down, etc. But it's better than having the talk bubble too far away.)
The name of the initial sprite (the Scratch cat) is now "Sprite1"
Bug fix: The cursor sometimes disappears when using the media library.

Paint editor:

Can now draw multiple rectangles or ellipses in bitmap mode without re-selecting tool (thanks, Shane!)
The Stamp tool in bitmap mode now works as users expect -- click the tool, then select the area to copy. No change to the behavior in vector mode.
Use cross-hair cursor for select/stamp tools.

Media library:

Evenly space columns to fit available space
Only show sprite's costume count when it is selected.

v279


adds "All" to the media library category filter (and makes that the default selection)
records project ID in saved project, allowing us to track remixes via download/upload (but still need to do something on upload)
records flash version, OS, and browser in saved project
increase autosave frequency 4x (now autosaves every 30 seconds) to simulate a higher server load
cloud data changes from Sayamindu (see his email for details)

v278

This version has a brand new media library UI for importing sprites, costumes, backdrops, and sounds. Brand new code, that is; it should look very similar to the old one.
The new media library UI is provided by the SWF, rather than a call to Gaia's JavaScript code. This allows it to work in the stand-alone version of Scratch 2.0 (including the "interim" stand-alone version). It also makes it easier for me to make changes and improvements. For example, I've optimized the thumbnail loading code to try to address some of the problems we've seen on slow networks, and I have another optimization in the works. In addition, this new code should fix issues with some SVG thumbnails being mis-aligned or cut off.
It also fixes a bug when importing multiple costumes/backdrops from the local computer.
I tried to follow Gaia's UI design as closely as possible, but there are some spacing and small font differences. Also, I did not implement the roll-over that shows the number of scripts/costumes/sounds in a sprite. Script/costume counts are now shown underneath the sprite name, allowing you to see at a glance which sprites have scripts or multiple costumes. However, if people prefer the roll-over approach, it's quite easy to implement.
v277

Fix the eyedropper bug.
v276


costume center tool has "ligher" [sic] icon and is aligned at top-left of canvas (so it that it's NOT directly above the vector tools)
icons for new costumes (vs. the drop-down menu)

...and some expert features:

in bitmap mode, shift-delete deletes everything EXCEPT the selection, like 1.4 (no equivalent in vector mode)
shift while drawing lines constrains lines to vertical or horizontal
shift while rendering (i.e. clicking away from the selected object) in bitmap mode does anti-aliasing (The result looks smoother but if you fill it using the paint bucket you get a "halo" of anti-aliased pixels of the old color around the edges, so you have to be sure you'll never want to use the paint bucket. Still, this mode makes text look much nicer.)

v275


top button row and bottom area now adapt to size changes
paint editor now fits on a 1024-wide screen (without shrinking the stage)
gradient on brightness slider
costume center button now in top row (next to flip buttons)
displays two color swatches (that swap when clicked)
background checker-board pattern now has smaller squares, like in Scratch 1.4 (requested by a user)
bug: large imported costumes were not being centered correctly ("oreo cookie" bug)

v274

Small reorganization of the mode label and set center tool button
v273

I just fixed two minor glitches with bitmap mode of the paint editor:

when editing a backdrop, picking up a selection would include a rectangle of white (background) pixels, making it harder to move and paste selections (the white pixels might cover up something you wanted to keep)
Text is no longer anti-aliased when it gets rendering into the bitmap. This allows you to fill individual letters with colors without leaving a "halo" of the old color (see samples below). However, small text now looks much more pixelated. We may want this to be a shift-option on the text tool (e.g. "Shift: Smoother text").

v272


Shane fixed two tricky bugs with the bitmap text tool. (Thanks, Shane!)
Shane also fixed an issue with the paint editor scrollbars.
I fixed one trivial bug with the bitmap flip buttons.

v271

I fixed the bug that was causing all of these:

I am seeing a problem with the bitmap fill.  I use the bitmap oval tool to make a new oval, then I select the bitmap fill and pick another color.  I then click on the oval to fill the oval - but the background fills instead of the oval.
When I draw with the bitmap pencil, it remains selected after drawing, so I can draw another line.  This does not happen when I draw an oval or a rectangle - the tool keeps defaulting back to the pencil.
Undo in the bitmap editor is acting oddly.  When I draw multiple lines with the pencil, it works properly:  each undo action removes one line drawn.  This does not happen as well when I have drawn ovals or rectangles:  one undo action can remove multiple ovals or rectangles - or an oval and a line.  Actually, I am now finding that if I start with a new costume and draw several ovals, the Undo option doesn't become available until I draw something other than an oval - it's like they are not being added to the Undo stack.

v270

v247


many changes to the paint editor
bug fix: make "keep on stage" function use integer positions (reported by Amos, tested by Mark)

v241

Features


support for a limited number of numeric cloud variables (max of 10 cloud variables per project, no cloud lists)

many "under the hood" changes working towards our two-image editor design, but the bitmap editor isn't available yet

Bug fixes

v239


Fix two editor problems

v238


rewordings of status and error messages from Natalie
new dialog box on save failure with options for re-try to local save
importing MP3 files now shows progress
all large sounds are now compressed (short sounds that you record yourself are not compressed, to avoid losing quality if you edit them)
imported assets are uploaded *before- they appear in the project
more progress dialogs so the user knows what's going on (Unfortunately, Flash does not make upload progress information available, so the upload dialogs are not as useful for seeing the actual progress as I'd like.)
SWF calls a JS function to report the number of sprites and scripts when the project has loaded (for Champika)

v237b

fixes for path editing (2-point paths, removing the 2nd to last point, and proper curves around closed path end points)
v237


Fixed issue with new "color touching" block code (It wasn't handling rotation and scaling of bitmap costumes correctly; I had only tested with SVGs.)
Fixed the 'delete key' bug when editing the costume name.
Added path cleaning for small paths but not thin paths.
Added new ways to connect paths (dragging end points and drawing between the ends of two paths).

scroll long menus when close to top or button (don't need to go above or below)
limit the speed of menu scrolling to 15 fps

v235
