* Update [bips.md](bips.md) to account for changes since the last release (don't forget to bump the version number on the first line).
* Update version in `configure.ac` (don't forget to set `CLIENT_VERSION_RC` to `0`).
* Write release notes (see "Write the release notes" below).
* Update `src/chainparams.cpp` nMinimumChainWork with information from the getblockchaininfo rpc.
* Update `src/chainparams.cpp` defaultAssumeValid with information from the getblockhash rpc.
- The selected value must not be orphaned so it may be useful to set the value two blocks back from the tip.
- Testnet should be set some tens of thousands back from the tip due to reorgs there.
- This update should be reviewed with a reindex-chainstate with assumevalid=0 to catch any defect
that causes rejection of blocks in the past history.
### Before every major release
* Update hardcoded [seeds](/contrib/seeds/README.md), see [this pull request](https://github.com/bitcoin/bitcoin/pull/7415) for an example.
* Update [`src/chainparams.cpp`](/src/chainparams.cpp) m_assumed_blockchain_size and m_assumed_chain_state_size with the current size plus some overhead (see [this](#how-to-calculate-m_assumed_blockchain_size-and-m_assumed_chain_state_size) for information on how to calculate them).
* Update `src/chainparams.cpp` chainTxData with statistics about the transaction count and rate. Use the output of the RPC `getchaintxstats`, see
[this pull request](https://github.com/bitcoin/bitcoin/pull/17002) for an example. Reviewers can verify the results by running `getchaintxstats <window_block_count> <window_last_block_hash>` with the `window_block_count` and `window_last_block_hash` from your output.
* On both the master branch and the new release branch:
- update `CLIENT_VERSION_MINOR` in [`configure.ac`](../configure.ac)
- update `CLIENT_VERSION_MINOR`, `PACKAGE_VERSION`, and `PACKAGE_STRING` in [`build_msvc/bitcoin_config.h`](/build_msvc/bitcoin_config.h)
