New Features and Changes
New Features
- Added new default automatic whitelist mode that automatically whitelists mods that have registered network channels as they are most likely to have server-side features that breaks when not whitelisted.
- Added alert suppression for benign signs and anvils to prevent key resolution alerts triggered by sign or anvil screen search inputs from server plugin.
- OpSec no longer conflicts with ExploitPreventer. When both mods are installed, overlapping features are automatically disabled and deferred to EP. Read More
Changes
- Channel spoofing is now enabled by default.
- Replaced local URL blocking with ExploitPreventer's HTTP redirect protection implemention. OpSec had a detection vector due to its lack of 305 redirect handing.
