+Pony version 0.35.0 is now available. If you are running Pony on an ARM based CPU, we recommend updating as soon as possible.
+<!--more-->
+
+Check it out!
+
+We've fixed a bug in the Pony runtime that would impact on ARM based CPUs and have undetermined, but definitely not good results. If you use Pony on ARM, update now.
+
+Otherwise, there's not a ton that's new in Pony 0.35.0. We've fixed a bug in the CommandParser package and introduced a breaking change to the ProcessMonitor package. Details are below...
+
+## Correctly report process exit status
+
+Processes spawned with `ProcessMonitor` that have been terminated by signals have been reported as exited with exit-code 0. Now `ProcessNotify.dispose` receives a `ProcessExitStatus`, which is either an instance of  `Exited` containing the exit-code, if the process terminated _normally_, or an instance of `Signaled` containing the signal number which terminated the process e.g. `9` if it has been terminated by `KILL`.
+
+Before (ponyc <= 0.34.1):
+```pony
+class MyNewProcessNotify
+    ...
+  fun ref dispose(process_monitor: ProcessMonitor ref, child_exit_code: I32) =>
+    if child_exit_code != 0 then
+      out_stream.print("non-successful run, terminated normally with " + child_exit_code.string())
+    else
+      out_stream.print(
+        """
+        factually either all good, terminated normally with 0,
+        or killed by signal, we simply dont know.
+        """)
+    end
+```
+
+After (0.35.0 and onwards):
+
+```pony
+class MyNewProcessNotify
+    ...
+  fun ref dispose(process_monitor: ProcessMonitor ref, child_exit_status: ProcessExitStatus) =>
+    match child_exit_status
+    | let e: Exited if e.exit_code() != 0 => out_stream.print("terminated normally with " + e.exit_code().string())
+    | let s: Signaled => out_stream.print("killed by signal  " + s.signal().string())
+    else
+      out_stream.print("exited with 0, all good")
+    end
+```
+
+## Fix CommandParser incorrectly handling multiple end-of-option delimiters
+
+Fixed an issue where CommandParser was incorrectly handling cases when arguments contain multiple end-of-option delimiters. For example, `corral exec -- lldb ponyc -- $(ponyc) -V=0 -o ./build/`.
+
+## [0.35.0] - 2020-05-11
+
+### Fixed
+
+- Fix CommandParser incorrectly handling multiple end-of-option delimiters ([PR #3541](https://github.com/ponylang/ponyc/pull/3541))
+- Correctly report process termination status in ProcessNotify.dispose() ([PR #3419](https://github.com/ponylang/ponyc/pull/3419))
+- Ensure non-blocking process wait and correctly report process exit status ([PR #3419](https://github.com/ponylang/ponyc/pull/3419))
+- Fix atomics usage related to actor muting for ARM ([PR #3552](https://github.com/ponylang/ponyc/pull/3552))
+
+### Added
+
+- Add Ubuntu18.04 builds ([PR #3545](https://github.com/ponylang/ponyc/pull/3545))
+
+### Changed
+
+- Ensure that waiting on a child process when using ProcessMonitor is non-blocking ([PR #3419](https://github.com/ponylang/ponyc/pull/3419))
