1. SCERT is improving text book printing infrastructure by shifting from Adobe 's softwares to FOSS based XeTeX and free licensed fonts.

2. They will shift from ASCII to Unicode . This will also help in universal access for differentially abled via technologies like Text to Speech even in Malayalam Language .

3. The books will be licensed under  CC-BY-SA . 

Official Order is still pending. But I am posting this since it is already in media reports.

Read a report in TOI http://timesofindia.indiatimes.com/home/education/news/Now-free-software-to-set-school-textbooks-in-Kerala/articleshow/25781341.cms

The Change will be applicable to all newly publishing books from now Starting from Malayalam Text books in 5, 7, and 11th standards

Myself, Hrishikesh K.B and a team from Swathanthra Malayalam Computing (http://smc.org) are working closely with SCERT from last few months to help  them in initiating this change process.  

Thanks to Dr. P.K Thilak, Research Officer  SCERT , Director SCERT, and  Biju Prabhakar IAS (Director of Public Instruction, Govt of Kerala )  for initiating this Change.
