=== Nasal load priority (version 2020.1) === | |||
Since version 2020.1 files that are listed in /Nasal/loadpriority.xml will be loaded first (in the order they appear in this XML). | |||
The remaining files will be loaded in alphabetical order. | |||
After some dependency checks, loadpriority.xml was filled with the relevant filenames. | |||
Most of the listeners (nasal-dir-initialized) have been removed accordingly. | |||
