{{External Programs}} {{other version|3.0|2.0|title=Development of Scratch 2.0|noversion=yes|1.0|title2=Development of Scratch 1.0}} [[File:Scratch 3.0 Editor Preview 1.png|thumb|350px|The first mockup of Scratch 3.0]] The '''development of [[Scratch 3.0]]''' was a process which took many years, starting long before the official release on January 2, 2019.<ref name="release">ceebee. (18/12/2018). "On January 2nd we are launching Scratch 3.0!" [[topic:325037]]</ref> == Pre-Preview == On May 17, 2016, the [[Scratch Team]] announced a partnership with Google along with [[Scratch Blocks]], a framework for the user interface of a graphical [[Programming Language|programming language]] that would be used in "the next generation of [[Scratch]]". (Scratch Blocks is based on Google's [[wikipedia:Blockly|Blockly]] and includes a "horizontal grammar", using icons rather than text labels, very similar to that of [[ScratchJr]].)<ref>https://medium.com/mit-media-lab/scratch-google-next-generation-of-programming-blocks-for-kids-5f377ec9ff0</ref> The same day it was demonstrated at the Google I/O Youth conference,<ref>https://developers.googleblog.com/2016/5/scratch-and-google-introduce-scratch-blocks.html</ref> and both Scratch Blocks and Scratch VM, which would serve as the Scratch [[Interpretation|interpreter]], were released as free software on GitHub.{{cite post|technoboy10|17/5/16|Also, https://github.com/LLK/scratch-vm is a cool thing that people should take a look at.|[[post:1989849]]}} Design concepts were also included.<ref>https://github.com/LLK/scratch-blocks/wiki/Design</ref> Initially, many blocks were missing, but these were steadily re-added. From this point the Scratch Team reviewed and accepted contributions from the community.{{cite post|joaoh1|7/7/16|(The Sensing Blocks PR got Merged)|[[post:2084844]]}} In August of 2016, Scratch Render, which draws the [[stage]] and [[sprite]]s, was released on GitHub.{{cite post|technoboy10|8/8/16|The renderer repo is now public on GitHub.|[[post:2140074]]}} In September, the Scratch Team placed ready-to-use "playgrounds" for Scratch Blocks and Scratch VM on the internet.{{cite post|NickyNouse|25/9/16|They just added this: http://llk.github.io/scratch-vm/|[[post:2221483]]}} In October, Scratch Audio Engine was released.{{cite post|liam48D|14/10/16|https://github.com/LLK/scratch-audioengine|[[post:2248200]]}} Around this time the [[Sound Effect|sound effect]] blocks were added, including echo and reverb effects.{{cite post|chooper100|26/10/16|I'd like to point out a couple of blocks in the sound category|[[post:2264092]]}} Finally, in November, Scratch GUI, the Scratch program itself, was released on GitHub.{{cite post|NickyNouse|9/11/16|https://github.com/llk/scratch-gui|[[post:2284480]]}} In contrast to [[Scratch 2.0]], the stage was placed on the right, as in [[Scratch 1.x]]. At this point, the [[Code Area|scripting area]] was a deep blue, and the [[Block Palette|block palette]] was transparent.{{cite post|_nix|5/1/17|Apparently the block palette is transparent,|[[post:2379699]]}} On September 30, designerd posted the first public concept sketch of Scratch GUI on GitHub.<ref>https://github.com/LLK/scratch-gui/issues/1#issuecomment-250742655</ref> In January of 2017 the background of the scripting area became a light gray, matching the concept sketch.{{cite post|chooper100|27/1/17|They removed the blue Scratch GUI background:|[[post:2418563]]}} In March, [[Variables Blocks|Data]] and [[More Blocks]] were removed from the block palette.{{cite post|NitroCipher|21/3/17|The Data (variables/lists) block and the Custom block categories are completely gone from the block palette.|[[post:2514706]]}} The costumes pane and sounds pane were finally added in April,{{cite post|Ed8|17/4/17|The tab are back again!|[[post:2565103]]}} and Data was re-added about a week later,{{cite post|Ed8|24/4/17|The data category has been added,|[[post:2577383]]}} but without [[wikipedia:Logo (programming language)|Logo]]-style indirection.{{cite post|stickfiregames|8/5/17|I've just been reminded of it - what happened to these?|[[post:2603447]]}} On August 23, [[() Contains ()? (Operators block)|<sb><[] contains []?></sb>]] was added.<ref>https://github.com/LLK/scratch-blocks/pull/1045</ref> On the 28{{th}}, the list of [[Block Categories|block categories]] was moved to the side of the palette,{{cite post|Ceo_|28/8/17|They changed something|[[post:2801586]]}}<ref>https://github.com/LLK/scratch-blocks/pull/1052</ref> similar to the [[Experimental Viewer|experimental viewer]]. On September 27 the block palette was changed to allow one to scroll through all the categories.<ref>https://github.com/LLK/scratch-blocks/pull/1059</ref> [[File:Scratch 3.0 プロトタイプ 20171009.png|thumb|Scratch GUI on 9/10/2017]] Pen became an [[Scratch Extension|extension]] in October{{cite post|Charles12310|20/10/17|Pen is now a Scratch extension:|[[post:2862587]]}} and the [[Music Extension|music blocks]] became an extension in November.<ref>https://github.com/LLK/scratch-gui/pull/870</ref> More Blocks was added to the block palette in December{{cite post|Sheep_maker|9/12/17|Custom blocks are now in /develop|[[post:2918993]]}} and renamed to "My Blocks" little over a week later.{{cite post|Charles12310|22/12/17|The block section that has custom blocks has been named “My Blocks”.|[[post:2932043]]}} A "give feedback" button,{{cite post|Sheep_maker|27/12/17|New “give feedback” button|[[post:2937667]]}} [[Set Drag Mode () (block)|<sb>set drag mode [ v]</sb>]],{{cite post|Ed8|29/12/17|New block!|[[post:2939737]]}} and [[Go to () Layer (block)|<sb>go to [ v] :: looks</sb>]] and [[Go () () Layers (block)|<sb>go [ v] () layers</sb>]]{{cite post|_nix|29/12/17|the layer blocks now let you select “forwards” (or “front”) instead of “backwards”/“back”:|[[post:2939753]]}} were added shortly after Christmas. == Preview == The preview of Scratch 3.0 let users take a better look at what the version would bring. Early in January, a welcome screen was added to Scratch GUI,{{cite post|Sheep_maker|3/1/18|New “welcome to the Scratch 3.0 preview” image:|[[post:2946352]]}} and the preview FAQ appeared about a week later.{{cite post|Meowlit12|11/1/18|Preview FAQ now works|[[post:2955399]]}} The preview was released at preview.scratch.mit.edu on January 18, 2018. {{cite post|thisandagain|18/1/18|We just updated the link for testing out the Scratch 3.0 Preview to https://preview.scratch.mit.edu|[[post:2963124]]}} (A snapshot of this preview from March of 2018 can still be viewed [https://llk.github.io/scratch-gui/vision/ here].) The following changes were made, among others, during the preview:<ref>https://github.com/LLK/scratch-gui/wiki/Release-Notes</ref> ;January * New sprites, backdrops, sounds, and costumes added to libraries ;February * New asset menu system including [[Surprise Button|surprise]] sprite, backdrop, costume, and sound buttons and blank sprite and backdrop button ;March * New menu bar ;April * The [[Video Motion Extension|video motion extension]] was added. * The appearance of the editor was improved.{{cite post|_nix|9/4/18|The entire editor is looking quite a lot bluer now!|[[post:3059404]]}} * Locally save and load SB3 files from your computer * Minor changes to block names and colors * Updates to the sprite/sound/costume tile design * New library design and improved search * Uploading sounds and costumes from file (svg, jpg, png, mp3, wav) * Initial version of the "How-To" library with step-by-step tutorials and videos ;May * Add font picker tool with several new fonts * [[Item Number of () in () (block)|<sb>(item # of [] in [ v])</sb>]] was added.<ref>https://github.com/LLK/scratch-blocks/pull/1425</ref> ;June * The [[Translate Extension|Google Translate extension]] was added. * Add a new menu item for "Choose a Sprite/Costume/Sound/Backdrop" to make the action menus more clear * Add new "baseball"- and "spooky"-themed sprites and backdrops * Updates to the How-To library ;July * New bitmap costumes and backdrops in the libraries * Interface updates for the "How-Tos", now called "Tutorials", including style changes to the menu bar and cards * Interface updates to the stage selector, making it more clear (blue) when it is the active target * Extension block updates: new color (aqua) and new icons * [[LEGO MINDSTORMS EV3 Extension|EV3 extension]] and [[Micro:bit Extension|micro:bit extension]] added * Updates to the tutorials library {{----}} == Beta == {{inaccurate|date=April 2022}} {{redirect|Scratch 3.0 Beta|the forum|Scratch 3.0 Beta (forum)}} The beta of Scratch 3.0 was released on August 1, 2018 at beta.scratch.mit.edu, alongside the Scratch 3.0 Beta forum.<ref>[[topic:308020]]</ref> Scratchers were encouraged to take a look at the beta and give their feedback to the Scratch Team in the forum. The beta marked the release of several extensions, and other prominent features in the editor. === Forum === {{main|Scratch 3.0 Beta (forum)}} [[File:3.0 Forum.PNG|thumb|The Scratch 3.0 Beta forum.]] The Scratch 3.0 Beta forum was created so that Scratchers using the beta of Scratch 3.0 could give their suggestions and ideas, as well as reporting any bugs they might find. The forum experienced a surge in activity when it was created. It was located at <nowiki>https://scratch.mit.edu/discuss/57/</nowiki> but has since been removed. Although it was created for the reasons stated above, many topics were simply complaints from Scratchers who did not like the beta and wanted to continue using Scratch 2.0.{{cite post|Darkslam|12/8/2018|i prefer the old version|[[topic:311702]] {{dead link}}}}{{cite post|ProGramure|12/8/2018|Dont change 2.0 please :( I dont want 3.0 2.0 is easier to use[title]|[[topic:311704]] {{dead link}}}} {{----}} === Bugs === During the beta phase, many bugs were fixed. Scratchers who tried the beta discovered bugs and reported them on a [[Post#Topics|topic]] made by the [[Scratch Team]]. ==== Examples of Bugs ==== * Miniatures of the Costumes Page not being scaled to the sprite size. * Video being enabled by default in in the video sensing extension ==== Fixes ==== * Fix for the bug where switching away from the code tab to the costumes or sounds tab could cause a crash * Fix for unreachable costumes/sounds at the bottom of a long list * Fix for sprite tiles disappearing after changing zoom level/resizing the window * Fix for the bug where one was able to undo back to other sprites' code on the workspace after switching sprites * Fix for the bug where sharing blocks multiple times could cause a crash * Fix for the bug where sprites imported from [[Scratch 2.0]] would not be in the correct layer order or sprite-selector order. == Final Release == [[File:Maintenance Mode.PNG|thumb|The "Final Release Maintenance Mode" screen.]] The final release was on January 2, 2019. The [[Scratch Website]] was put into [[Maintenance Mode]] starting at 7:00 AM EST.<ref name="release" /> When one tried to access the Scratch Website during maintenance mode, this screen would show, saying that "the new Scratch is almost here! Check back later today" with a link to the Scratch Team's Twitter Account saying "follow us for updates." In the early afternoon EST, the website was put back and Scratch 3.0 was officially released.{{----}} == Gallery == {{:Scratch 3.0 Gallery}} == References == <references /> {{Scratch Versions}} [[Category:Scratch Versions|3.0]] [[Category:Scratch 3.0]]
