#LRS changelog

This history contains released Simplest Data LRS versions. Product release numbers are separate from xAPI protocol versions.

#1.0.3 — Codd

Published as an immutable linux/amd64 artifact. Version 1.0.3 is the current recommended Developer LRS release; 1.0.1 and 1.0.2 remain supported as historical releases. CLI and distribution updates reuse the existing artifact. The public workflow remains Local / self-managed; AWS qualification is a separate gate.

See the 1.0.3 release facts and immutable digest.

#1.0.2

Managed-runtime qualification and hardening improve managed PostgreSQL bootstrap compatibility. Role bootstrap converges and verifies restricted roles without requiring native PostgreSQL SUPERUSER behavior for roles already in the expected state; corrections still require appropriate administrator authority and fail closed when the required posture cannot be established. Migration/runtime role separation and RLS protections remain preserved.

Published as an immutable linux/amd64 artifact. At publication, version 1.0.2 became the current recommended Developer LRS release; 1.0.1 remained supported as a historical release. The public workflow remains Local / self-managed.

See the 1.0.2 release facts and immutable digest.

#1.0.1

Initial supported release of the canonical Simplest Data LRS application artifact for the Developer LRS distribution.

#Included in LRS 1.0.1

• Packaged the canonical LRS application runtime with Bash, PostgreSQL client tooling, canonical role bootstrap, reviewed ownership reconciliation, Alembic migrations, and runtime-grant reconciliation.
• Established the LRS-owned canonical schema lifecycle, including the statement ledger and transactional outbox implemented by the release migrations.
• Provided canonical runtime startup with /healthz liveness and /readyz readiness endpoints.
• Shipped implementation-backed xAPI behavior advertising protocol versions 1.0.3 and 2.0.0.
• Published the validated application artifact immutably for linux/amd64.

#Supported distribution and runtime tooling

The Local / self-managed Developer LRS distribution supports LRS 1.0.1 with tooling outside the application image:

• governed exact-version acquisition of the approved immutable digest;
• the simplestlrs local lifecycle CLI;
• external Docker Compose orchestration;
• a separately pinned PostgreSQL 16 runtime dependency and persistent database storage.

These capabilities acquire and operate LRS 1.0.1; they are not embedded in the application image.

See the 1.0.1 release facts, acquisition guide, and quickstart.
