April 2025 — erigontech/erigon: Strengthened stability and upgrade readiness by removing the deprecated MDBX Coalesce option from MDBX configuration to align with MDBX v0.12/v0.13 practices. This prevents misconfiguration and breakage during upgrades, improving deployment reliability for users relying on the MDBX-backed storage layer. Change implemented in commit e664c3e599086a8471f54d3a26f40adf3f3acd31 with message 'fix: mdbx.Coalesce is deprecated: always turned on since v0.12, deprecated since v0.13 (#14640)'.
