 ## Version History
 
+### Development Build: 1.4.11
+
+- Removes non-termination string warnings when building with GCC9.
+- Exception handling is now implemented on POSIX. There is no longer a separate handler for SIGINT - it is now treated as an exception and goes through the normal process which ends up "restarting" CFE. On pc-linux causes the process to exit normally. There is now a mechanism to capture the CTRL+C exception code and use it during normal test cycles.
+- See <https://github.com/nasa/PSP/pull/160>
+
 #### Development Build: 1.4.10
-  - Implements full-precision microsecond conversion
-  - See https://github.com/nasa/PSP/pull/155
 
-#### Development Build: 1.4.9
-  - RTEMS builds successfully without errors
-  - Build script uses a proper CMakeLists.txt instead of the aux_source directory
-  - Minor updates (see https://github.com/nasa/PSP/pull/153)
