Casey, the founder of Ordinals, posted on X platform that the ord 0.19.1 version has been released, with a significant change: the new full index is now 221 GB instead of 289 GB, saving 68 GB of space. This is a complete index that includes Sats, addresses, and runes. Partial indexes should also be smaller. The cost savings are due to a simple commit that resolves an error in redb, which caused it to only reuse pages released before two transactions instead of the last one.
