+# Notes / Changes in various releases
+
+## Zephyr SDK 0.11.2
+- Fixed issue with setjmp/longjmp not existing on x86 32-bit build
+- Fixed python support on GDB:
+  NOTE: Since python support is enabled in GDB the host system needs
+  python3.6 installed.  Otherwise you might get an error like:
+
+  ```
+  arm-zephyr-eabi-gdb: error while loading shared libraries: libpython3.6m.so.1.0: cannot open shared object file: No such file or directory
+  ```
+
+  On newer fedora systems this can show up and be fixed by:
+
+  `sudo dnf install python36`
