Bug Fixes
- Fix a failure to start sandboxes that were created with older versions of the CLI.
- Fix a file descriptor leak on Linux. Each credential lookup left a session
D-Bus socket open, so long-running processes (such as the daemon) could
gradually accumulate open file descriptors and eventually hit the session
bus's connection limit, failing with "The maximum number of active
connections has been reached." Connections are now closed after each
operation. macOS and Windows were not affected.
