 ## Previous Releases of MOARdV's Avionics Systems
 
+### MAS v1.3.5
+For KSP 1.12.3, 10 September 2022.
+
+**ATTENTION PLAYERS:** MAS includes a Module Manager patch that replaces all of the stock RPM props with MAS-enabled props.  If, for some reason, you do not want your RPM IVAs upgraded, you will need to rename GameData/MOARdV/Patches/JsiToMasUpgrade.cfg to JsiToMasUpgrade.nocfg.
+
+**NOTE:** A partial ASET Avionics and ASET Props upgrade patch is included, but disabled.  To try it, please rename GameData/MOARdV/Patches/AsetToMasUpgrade.nocfg to GameData/MOARdV/Patches/AsetToMasUpgrade.cfg.  Currently, you will need RasterPropMonitor installed to enable any props that are not already updated.  There are no guarantees that partially-updated IVAs will work perfectly.
+
+Outstanding known issues are logged at the [GitHub Issues](https://github.com/MOARdV/AvionicsSystems/issues) page.
+
+#### New Features
+* MAS provides additional logging when Verbose Logging is enabled in the MAS App menu to list the MAS_PAGE and MAS_SUB_PAGE nodes found in the game database.
+* MAS_PAGE loading should be faster for IVAs using multiple MFDs.  This improvement will manifest as quicker transitions to the Flight scene.
