Expand description

The database format minor version, incremented each time the on-disk database format has a significant data format change.

Significant changes include:

  • adding new column families,
  • changing the format of a column family in a compatible way, or
  • breaking changes with compatibility code in all supported Zebra versions.

Version history:

  • 28.0.0: the NU6.3 Ironwood shielded pool. Adds the ironwood_* column families (initially empty) and widens the chain value pool ValueBalance serialization from 40 to 48 bytes for the ironwood pool (read code accepts 32/40/48-byte records). Also widens the history-tree zcash_history::Entry records from 253 to 326 bytes, because NU6.3 adds Ironwood fields to zcash_history::NodeData (read code accepts the legacy 253-byte width and zero-pads it up to the current width). New CFs are created and the wider records are read in place when the database is opened, so this is a major bump that is restorable from the previous major database format version (no resync, no data migration).
