历史

Main article: Scratch 2.0的开发阶段

Scresch 2.0由andresmh2010年1月在Scratch论坛上宣布[4] Scratch团队进行2.0开发的一部分首次发布的实验是2010年8月的实验查看器.[5] 后来,在2011年,为项目发布了测试版Flash 播放器,登录用户可以选择使用。 2012年,它被alpha编辑器的版本所取代; 这个版本是10月份所有用户的默认版本。

2011年5月,第一个已知版本的项目编辑器预内测版在Scratch 日 @ MIT发布给了有限的Scratcher。又过了一小会儿,Scratch团队开始在他们的博客上公布更新,即Scratch 2.0 进度报告 alpha(alpha.scratch.mit.edu)阶段有新的网站和重新设计的项目编辑器,并在一年后,2012年的Scratch日上首次向公众展示。在2012年的剩余时间里,人们被引进来测试这个版本:社群管理员和选定的教育工作者; Collab Counselors,前策展人Scratch创作坊策展人,[[Zho:TBG] |TBG]]版主,以及一组500名志愿者。 由于故障,一些用户也能够渗透并使用该程序。[6] 2012年12月,公开测试版宣布于2013年1月28日开始。从那时起,它一直在beta.scratch.mit.edu上发布,直到全部发布完成为止。 它取代了以前的网站。

The beta version of the offline Scratch 2.0 editor was released on August 26 and can be downloaded here. It has very few differences from the online editor, most notably, though, the lack of the 背包. The offline editor receives updates without having to reinstall the entire program.

主要功能

Scratch has been completely rewritten in Adobe Flash for version 2.0 but still runs projects from older versions of Scratch. It is still completely free and without ads. Due to the new features and different programming language, Scratch 2.0 projects are saved in the .sb2 format instead of the previous .sb format. However, projects uploaded from Scratch 1.4 can still be downloaded from the 专案页面 in the .sb format. Scratch 2.0 features many new additions to both the program and website.

Caution (2).png Caution: Once a project is saved in the Scratch 2.0 editor, its format will be adjusted to .sb2 and cannot be reverted without the use of an external program. This means it cannot open in Scratch 1.4.
