 - This file lists changes for RPU only (since RP 2.3.3).
 - In addition to the below list, RPU releases contain all applicable fixes from the corresponding [UPU releases](https://github.com/BGforgeNet/Fallout2_Unofficial_Patch/blob/master/docs/changelog.md).
 - Sometimes UPU or RPU may be updated independently, which is why you might see gaps in version numbers.
-- Versions `2.4.*` contain [updated maps](https://forums.bgforge.net/viewtopic.php?t=371) produced by Pixote, and relevant script changes. Otherwise, they follow the same patch level convention.
