🔇 Additional comments (2)

params/version.go (1)

27-27: LGTM! Patch version increment is appropriate.

The patch version bump from 11 to 12 is consistent with the dependency update in go.mod.

go.mod (1)

56-56: Verify V0.9.0 codec changes are compatible with blob decoding and DA batch processing.

v0.9.0 introduces Codec V9 (galileo) with updated compressed-data compatibility logic and new RLE/ZSTD block handling. The codec now uses V9 compatibility checks by default, and downstream code that decodes/validates Scroll DA blobs or estimates L1 commit sizes should be tested/updated accordingly.

The codebase uses da-codec for blob decoding in commitV7.go, DA chunk decoding in commitV0.go and commitV1.go, and related operations in rollup_fee.go, da.go, and reader.go. Verify that these decoder functions (codec.DecodeBlob(), codec.DecodeDAChunksRawTx(), codec.DecodeTxsFromBlob()) remain compatible with V9's new compression compatibility rules and blob construction behavior, and run integration tests to ensure DA batch processing works correctly with the updated codec.
