+Version 1.2.3
+-------------
+
+- Disabled uploading mods to the master server by default as this is mostly
+  just a waste of bandwidth with the mod portal being integrated into the
+  game now.
+- Fixed researchSync breaking with heavily modded games due to the tech tree
+  exceeding the default 100kb limit on JSON payloads.
+- Fixed the command inventoryImport sends referencing player instead of
+  character, and trying to count the non-existant quick bar slots.
+- Fixed inventoryImport never receiving the script output after the default
+  mode for reading script output changed to tail mode.
+- Fixed desync caused by the mods and loaded mods arrays in Hotpatch getting
+  out of sync when plugins update their scenario mod code.  To fix existing
+  games you will need copy lib/scenarios/Hotpatch/hotpatch/mod-tools.lua
+  over the existing mod-tools.lua in the save's hotpatch folder.
+- Updated the Windows install instructions.
