Sometimes, I use any of the following mentioned names to name the install/upgrade scripts in custom modules:
install-0.1.0.0.php
upgrade-0.1.0.0-0.1.1.0.php
upgrade-0.1.1.0-0.1.2.0.php
----------------------------
install-0.1.0.php
upgrade-0.1.0.0-0.1.1.php
upgrade-0.1.1-0.1.2.php
Is there a standard way to follow for this naming conventions for install/upgrade scripts?
