This update is only needed for those that have set the "strictLinking" configuration item to false and wish to link portals in the same world. There is a known issue with linking portals in the same world (that is, the entry portal and linked exit portal are in the same world) that causes entities to be destroyed instead of transported (SPIGOT-6782).
Until this bug is resolved, there will be a workaround that is enabled by default in which the plugin will cancel the portal activation and teleport the entity directly, doing its best to simulate portal mechanics including cooldown. This new workaround appears to be reliable. However, there may yet be differences in behavior in which the simulated behavior does not exactly duplicate what would happen had the entity actually used the built-in server algorithms for portals. This is unlikely to manifest during casual use, but may become an issue when used in high-performance farms that depend on very specific portal mechanics for proper operation.
