+
+Multiple fixes:
+
+• Concurrent.Promise: Fixed race-condition in finalise().
+
+The API for finalise() raced with on_{success,failure}(), as
+new callbacks could get registered after finalise() was called,
+but before the state was updated.
+
+Fixes #10055.
+
+• Tools.Standalone.httpserver: Fix directory traversal vulnerability
+
+Thanks to Chris Angelico <rosuav@gmail.com> for the report.
