What is NATS?

NATS 2.15 ships a desired-state reconciliation engine that rewrites how JetStream handles cluster maintenance and failure recovery

NATS is shipping two active release lines simultaneously: 2.14.x for stability (at v2.14.7-RC.1) and 2.15 entering release candidate with a fundamental rework of stream and consumer state management. The 2.14 series has logged dozens of targeted filestore correctness fixes, Raft edge-case patches, and lock contention improvements — steady hardening work without user-visible behavior changes.

What is Scalingo?

Scalingo removes swap for new apps while keeping runtime dependencies current

Scalingo's recent changelog is dominated by buildpack dependency updates — Node.js 24.x and 26.x, Go 1.26/1.27, PHP 8.4/8.5, and Python ecosystem tools (uv, Poetry, Pipenv). The most operationally significant change is a platform policy effective 1 September 2026: newly created applications no longer use swap memory, and existing apps will have their swap capped at 25% of container memory after next restart.

NATS 2.15 ships a desired-state reconciliation engine that rewrites how JetStream handles cluster maintenance and failure recovery

◆ Current state

NATS is shipping two active release lines simultaneously: 2.14.x for stability (at v2.14.7-RC.1) and 2.15 entering release candidate with a fundamental rework of stream and consumer state management. The 2.14 series has logged dozens of targeted filestore correctness fixes, Raft edge-case patches, and lock contention improvements — steady hardening work without user-visible behavior changes.

◆ Where it's heading

The 2.15 desired-state metalayer is the most structurally significant JetStream change since the original release: streams and consumers are now reconciled against declared desired state rather than managed imperatively. This enables cancel-in-flight moves, safe node evacuation, and disaster-recovery rescue for clusters that have lost quorum — operations that were previously impossible or required manual intervention. The sustained 2.14 backport cadence shows the team is catching bugs at production-scale cluster edge cases while the 2.15 architecture matures in RC.

◆ Prediction

2.15 stable will land within weeks once RC.1 feedback is incorporated. The desired-state engine will unlock maintenance operations (zero-downtime scale, node evacuation, quorum recovery) that currently require downtime, and expect the 2.15.x patch series to begin shortly after as operators stress-test evacuate and rescue endpoints at scale.

Scalingo removes swap for new apps while keeping runtime dependencies current

◆ Current state

Scalingo's recent changelog is dominated by buildpack dependency updates — Node.js 24.x and 26.x, Go 1.26/1.27, PHP 8.4/8.5, and Python ecosystem tools (uv, Poetry, Pipenv). The most operationally significant change is a platform policy effective 1 September 2026: newly created applications no longer use swap memory, and existing apps will have their swap capped at 25% of container memory after next restart.

◆ Where it's heading

Scalingo is moving toward harder memory limits that require applications to be correctly sized rather than relying on swap as a buffer. The no-swap policy, combined with consistent runtime version currency, suggests the platform is prioritizing reliability and predictable performance over forgiveness. Existing apps face a real deadline at end-of-2026 when the swap cap takes effect after any restart.

◆ Prediction

Expect continued weekly runtime version bumps and likely documentation or tooling additions to help users adapt their applications to the no-swap policy before the end-of-2026 deadline.
