 ## grblHAL changelog
 
-<a name="20250229">20250229
+<a name="20250305">20250305
+
+Core:
+
+* Fixed ioports enumeration issue affecting remapped ports used by the ESP-AT plugin and stream passthru mode.
+
+* Changed stream passtrhu mode to not enter coprocessor MCU bootloader mode when turned on.
+
+Drivers:
+
+* Networking capable: updated for networking library changes. Some updated for incorrect sequencing of network events causing static IP mode to fail.
+
+Plugins:
+
+* Networking: next step in making library capable of supporting multiple interfaces.
+
+* WebUI: updated for networking library changes.
+
+* Misc, ESP-AT: updated to allow it to be used with controllers with ethernet enabled.
