Release Note

Change log:
Hard fork specific changes:

Decrease sprint length from 64 to 16
Increase baseFeeChangeDenominator from 8 to 16

New-cli:

Pruning has been introduced in the new-cli (using the command bor snapshot prune-state). The internal mechanism of pruning will work in the same way as it used to with the previous versions. The command snapshot prune-state will be available as a subcommand of the bor binary and will accept relevant flags (e.g. datadir). More details can be found here.
Adds support for a new flag for tweaking the number of tries in memory (—cache.triesinmemory, default: 128) (https://github.com/maticnetwork/bor/pull/552).
Updates and improvements in the description and documentation of the flags in new-cli along with their default values in the help command.

Improvements and feature additions:

GRPC integration for bor and heimdall (https://github.com/maticnetwork/bor/pull/468).
Improve bor’s interaction with heimdall by using context based cancellation methods in heimdall client and bor consensus (https://github.com/maticnetwork/bor/pull/445/).
More improvements on checkpoint based validations while importing new blocks to control reorgs (https://github.com/maticnetwork/bor/pull/425).
Improvement and fixes in eth_getTransactionReceiptsByBlock rpc call which used to return wrong results when state-sync transactions are present and unit tests for the same (https://github.com/maticnetwork/bor/pull/477).
Replace mutex wherever possible with atomic pointers (introduced in go 1.19) (https://github.com/maticnetwork/bor/pull/446/).
Add new metrics in heimdall client to measure requests (like valid/invalid requests, duration of each request, etc) (https://github.com/maticnetwork/bor/pull/459).
Add traces (available through open-telemetry tracing) in whole mining process to measure time taken by each component in building a new block to make improvements in future (https://github.com/maticnetwork/bor/pull/429).
Enable tracing support for state-sync transactions in debug requests (https://github.com/maticnetwork/bor/pull/547).
Minor bug fixes and improvements across other modules.

Testing and benchmarking

Restore geth tests (https://github.com/maticnetwork/bor/pull/436).
Benchmark mining operations to make it more optimal to use (https://github.com/maticnetwork/bor/pull/439).
More unit tests for testing the consistency of validator set operations (e.g. handling priority and power of validators in set) in bor consensus (https://github.com/maticnetwork/bor/pull/452).
e2e tests for bor receipt calculations (https://github.com/maticnetwork/bor/pull/431/).
Unit tests for bor specific filters (https://github.com/maticnetwork/bor/pull/456).
Unit tests for scenarios when validator comes back online after a crash and tries to reorg (https://github.com/maticnetwork/bor/pull/507).
Property based tests on transaction pool have been added to make improvements in future (https://github.com/maticnetwork/bor/pull/466).
