@SK Actually we are working on the next release which will be focused on tags. Meanwhile, we are working on Tables and a web version. After tables, we'll address cryptography in dept but we may integrate touchID locking before.
The answer is Soon-ish, will not be in the next major update and probably not the one after too. Encryption has to be tested heavily before release and probably we'll do more rounds of beta testing before the effective release.
@TomL I everything fine we will begin encryption integration after 1.5 release. There is a huge paperwork we have to produce and get approved in order to ship encryption in some countries and at the moment I'm terrified by the idea to get stuck in some bureaucracy wheel.
