       functions previously accounted between 3 and 7% of CPU usage on
       some busy relays. Resolves ticket 9841.
     - Avoid wasting CPU when extending a circuit over a channel that is
-      nearly out of circuit IDs. Previously, we would in the worst case
-      do a linear scan over all possible circuit IDs before deciding
-      that we had exhausted our possibilities. Now, we try at most 64

   o Major features (seccomp2 sandbox, Linux only):
     - The seccomp2 sandbox can now run a test network for multiple hours
       without crashing. The sandbox is still experimental, and more bugs
       will probably turn up. To try it, enable "Sandbox 1" on a Linux

     - When the sandbox blocks a system call, it now tries to log a stack
       trace before exiting. Resolves ticket 11465.
   o Major bugfixes (TLS cipher selection):
     - The relay ciphersuite list is now generated automatically based on
       uniform criteria, and includes all OpenSSL ciphersuites with
-      acceptable strength and forward secrecy. Previously, we had
-      omitted some perfectly fine ciphersuites. Resolves bugs #11513,
