This updates the blockchain/stake module dependencies, the copyright year in the files modified since the previous release, and serves as a base for blockchain/stake/v4.0.0. The updated direct dependencies in this commit are as follows: - github.com/decred/dcrd/database/v3@v3.0.0 - github.com/decred/dcrd/dcrutil/v4@v4.0.0 The full list of updated direct dependencies since the previous blockchain/stake/v3.0.0 release are as follows: - github.com/decred/dcrd/chaincfg/chainhash@v1.0.3 - github.com/decred/dcrd/chaincfg/v3@v3.1.0 - github.com/decred/dcrd/database/v3@v3.0.0 - github.com/decred/dcrd/dcrec/secp256k1/v4 v4.0.1 - github.com/decred/dcrd/dcrutil/v4@v4.0.0 - github.com/decred/dcrd/txscript/v4@v4.0.0 - github.com/decred/dcrd/wire@v1.5.0 - github.com/decred/slog@v1.2.0 The following direct dependencies are no longer required as compared to the previous release: - github.com/decred/dcrd/dcrec Finally, all modules in the repository that depend on the module are tidied to ensure they are updated to use the latest versions hoisted forward as a result.
