CheerpJ 1.2 released - ProGuard integration, system clipboard support

[Stefano De Rossi (LT)]

Dear all,

we have released CheerpJ 1.2, the latest major update to our Java to JavaScript compiler. CheerpJ 1.2 can be downloaded from our website - release announcement on our blog.

Release 1.2 introduces two features which have been highly requested by our commercial users: an integration with ProGuard to allow major reductions in startup time and download size, and full integration with the system clipboard, allowing to copy and paste between the browser and the system. This release introduces further optimisations to memory use, size of generated code and networking.

To try CheerpJ 1.2, download the new version of the compiler, and follow our tutorials to get started. If you have been using a previous version of CheerpJ, *make sure to rebuild your project*, and change your CheerpJ runtime header to

Best regards,
Leaning Technologies
