Voting is open for a new IC release - a939fed

Hello there!

we are happy to announce that voting is now open for a new IC release .
The NNS proposal is here: IC NNS Proposal 73959.

There are lots of exciting new features and bugfixes. Here is a more complete list of changes:

* Consensus: Check membership when verifying signatures in canister http pool manager
* Consensus: ECDSA pool improvements
* Consensus: Hard limit for Bitcoin network
* Consensus: Remove unused argument
* Crypto: Add sum-of-products operations for BLS12_381 G1
* Crypto: Avoid panic in impl Ord for Scalar
* Crypto: Convert NI-DKG Proof of Possession implementation away from MIRACL
* Crypto: Convert verify_ciphertext_integrity away from MIRACL
* Crypto: Fix bitrot in the tECDSA fuzzers
* Crypto: Fix risky panics in threshold code
* Crypto: Add ECC point negation for IDKG
* Crypto: Add EccPoint negate function for IDKG, tests and a seeded PRG function in test_utils
* Crypto: Improve error messages where CspSecretKey::algorithm_id() was called
* Execution: Bitcoin: Fix bug in `get_utxos` that returns spent UTXOs.
* Execution: Extract and store effective canister id from ingress
* Execution: Move max_number_of_canisters_pot from legacy to upgraded pot
* Execution: Scheduling subnet messages for DTS
* Execution: add `reference_subnet_size` for scaling the cycles cost
* Execution: add `subnet_size` to `canister_creation_fee`
* Message Routing: Allow rerouting back in case of migration rollback
* Message Routing: Available canister IDs metric
* Message Routing: Canister deletion respects canister migrations entry
* Message Routing: Runbooks for checkpoints/files accumulating on disk
* Message Routing: Switch canister ID generation to allocation ranges
* Networking: Add a new connection duration metric
* Networking: Change testing proxy canister interface
* Networking: Check for existing peer connection before we do the TLS handshake.
* Networking: Disable btc balance test
* Networking: Hold exclusive lock for on peer_map only when we add/remove peer. For connection state transition we don't need exclusive lock.
* Networking: Make spawn_(write|read)_task associated function and delete try_transition_to_connected
* Networking: Mixed workload documentation.
* Networking: Use tokio sync primitives
* Node: Limit traffic through `ic-canister-http-adapter`
* Orchestrator: Improve the probing for a non-functional subnet
* Orchestrator: proper validate replay
* Runtime: Allow to change compute allocation during install
* Runtime: Cache failed compilations
* Runtime: Compilation cost for failed compilations
* Runtime: Unify applying of execution and system state changes
* Runtime: Use 0 instructions when compilation fails
* Runtime: Use the unzipped module size for compilation cost
* Various tech-debt management: code refactoring, docs, bug fixes, test updates

And a complete list of changes can of course be found on GitHub.
