Drush Lock: Freeze the version of a Module during 'drush up'

Every so often I will find myself needing to update lots of Drupal modules but not one in particular. Perhaps I have patched the module, or perhaps there is a new version of the theme that I know will break my site layout.

Drush can save you from this dilemma, as of version 4.x - yes, it's true!

Just use:

drush up --lock=omega

Assuming Omega is the project that needs to keep the same version number. Omega will not be updated until you reverse the lock.

drush up --unlock=omega

You can also just:

drush up omega

If you want to.
