I have two branches like dev and master in VSTS to manage my code. After completed phase 1 development, I have published my web application code from master branch through my Dev Ops configuration.
But every day we do pull request from dev to master, so every day master having latest code.
I have doubt like
After completed phase 1, my development team will started to work on phase 2 development on dev branch. But at some point time customers will raise the bugs/errors on phase 1 release of web application at that time how to quick fix those issues of phase 1 web application without interrupting the phase 2 development already started. Can you please tell what is the best approach to quick fix the errors/bugs in phase 1 and how to release only phase 1 code after fixed the errors/bugs.
