We are very glad to announce the E-Maj 5.0.0 version.

Among improvements, this major version:

  • Allows non-superuser roles to install and use E-Maj in a database, the usable features depending on the priviledges they own.
  • Eases writing idempotent administration scripts and managing E-Maj parameters.
  • Brings the PostgreSQL 19 version compatibility.

The Emaj_web client has been enhanced too, in particular to take benefit of these new features.

E-Maj is a PostgreSQL extension which enables fine-grained write logging and time travel on subsets of the database.

E-Maj 5.0.0 is compatible with Postgres 14 to 19 versions. Emaj_web 5.0.0 is compatible with emaj extension 3.0 to 5.0 versions.

The full documentation is available on line. The core extension is available at pgxn.org for installation or github.org for development.

The Emaj_web client is also available at github.org.

Have fun with E-Maj !
