Activate "checked" mode on a released C2 version

Is it possible to activate the same "checked" mode in a released version as the beta versions have?

One of my plugins had a duplicate expression id, one of them was "ef_deprecated" so I missed that during test with a released C2.

However it blow up when used with a beta version due to the checked mode, so I really would like to catch this kind of problems even with a released C2.

Checked mode has a performance overhead, so it's deliberately turned off for stable releases. You should just make sure you test with beta releases.

I am not always picking up a beta as it makes the capx not compatible with the released version. I can't send out demo capxs created with a beta version.

Is there a smart way to have both a beta and a released version side by side?

Arne - yes, you can install betas next to stable releases, just choose a different install directory and don't uninstall when given the option.
