There are a number of changes to Mentat's storage schema and capabilities that are an 'event horizon' for syncing: older clients would be unable to sync across it.

We will be addressing this via built-in schema versioning, but it's prudent to track work that would trigger this.

More datatypes (#201): big integers (#280), JSON (#31), non-ns keywords (#285), URIs (#431)
Directory-based and alternate file format (#97, #129, #541)
Alternate datom flag format (#29)
More schema alteration support and simpler transacts for schema changes (#105, #379, #121)
Excision (#21)
:db/noHistory (#102)
Hash-based indexing (#69)
Tabular representations (#33)
