Immutable database with cryptographic verification and tamper evidence

immudb.io ↗

immudb 1.11.0 added PostgreSQL compatibility — tamper-evident storage now accessible to ORM-based stacks.

◆Current state
immudb is in a 1.11.x maintenance cycle after the substantial 1.11.0 release, which added PostgreSQL ORM compatibility (pg_catalog, information_schema), structured audit logging with tamper-proof JSON events, and a new --audit-verif flag. The 1.11.2 maintenance release fixes a transaction survival issue when a statement fails before execution — a correctness fix for edge cases in transaction handling. The v2.0.0-RC1 from early 2025 introduced a different architecture (new indexing layer, simplified API), but 1.11.x appears to be the active production track.
◆Where it's heading
The PostgreSQL compatibility push is the clearest directional signal: immudb is trying to become accessible to developers using standard ORMs without learning immudb's native API. Combined with the structured audit logging, the pitch is a tamper-evident backend that behaves like PostgreSQL for existing toolchains. The v2.0.0 architecture rework remains an open question — whether it reaches GA or gets merged back into the 1.x line is unclear from the releases shown.
◆Prediction
A stable v2.0.0 release or clear abandonment of the v2 branch in favor of continued 1.x enhancements is the next decision point. The PostgreSQL compatibility work will likely expand to cover more pg_catalog views needed by common ORMs.

    immudb 1.11.2 — Transaction Fix

    1.11.2 fixes a transaction survival issue: a statement that fails before execution (e.g. a parse error) no longer aborts the surrounding transaction. A narrow but important correctness fix for applications that expect standard transaction semantics.

    immudb version 1.11.1

    1.11.1 adds sysadmin permission support to the immuadmin CLI (enabling additional sysadmin accounts without the default immudb account) and a new --audit-verif flag for auditors — practical operational improvements for deployments with multiple administrators.

    Immudb version 1.11.0

    ⚡ SPARK

    immudb 1.11.0 ships PostgreSQL ORM compatibility via pg_catalog and information_schema support, plus structured tamper-proof audit logging via --audit-log. These two additions expand immudb's accessible audience (developers using standard ORMs) and its compliance value proposition (immutable audit trails) simultaneously.

    immudb v2.0.0 — Architecture Overhaul RC

    ⚡ SPARK

    v2.0.0-RC1 proposes a major architectural overhaul: new indexing layer, simplified API, and performance improvements — a rebuild rather than an extension of the 1.x line. As an RC from 2025 that hasn't reached GA, it represents either a long-gestating major version or a parallel exploration that hasn't been committed to production.
