[RFC] Release process

The idea is to have
1. Frequent releases: we should ship features as soon as they are done.

We can start with a bi-weekly release schedule - every 2 weeks we release new features that we are have been working on. We can tweak this as and when it is required (maybe a larger window if we are working on large features). There will always be cases where we will have to make releases outside this cycle - critical bug fixes, security fixes etc.

2. Stability: the aim is to reduce the number of cases where we need to do an immediate patch release to fix an issue.

We will have a beta channel where a release goes first, fix any issues reported by the users and then promote it as a stable release.

We can follow Rust's release process:
