This isn't new. NCERT books have been online for several years.
Also, the article mentions that NCERT books were available for month and a half. Which is false. NCERT books have been available for free for years, they just also made them available on a few e-book formats a month or so ago, in addition to already available PDF. Cheap headline grab.
All CBSE books that they can publish that are not NCERT is an almost empty set.
