+**WARNING** If you choose not to upgrade to 1.0 beta 3 yet, be aware that a new version of Dedicated Pistol Slot mod will cause issues with pistol slots in existing campaigns. See [this Reddit post](https://www.reddit.com/r/LWotC/comments/gcmn9k/warning_prepare_for_changes_to_dedicated_pistol/) for details and a solution.

+**Mod dependency changes** Dedicated Pistol Slot and Revival Protocol Fixes are now integrated into LWOTC and incompatible with it. You will need to unsubcribe from them or disable them.

 **IMPORTANT** If you're upgrading from beta 2 or a development build and want to continue an existing campaign, make sure you load a strategy save after the upgrade, i.e. one that was created while you were on the Avenger. Also, use the new `RespecSelectedSoldier` console command on your faction soldiers to get the new ability trees.
