What is GitLab?

GitLab leans into 'no training on your data' as the wedge against Atlassian and GitHub.

GitLab's recent feed is heavy on positioning content rather than feature drops. The most pointed entry calls out Atlassian's August 2026 default-on data collection (and GitHub's Copilot data policy change) and stakes GitLab's counter-position: no training on customer data, regardless of tier. Around it: a UX research synthesis on agentic AI collaboration patterns across 17 platforms, security-team blog posts on threat intel and detection testing, and the routine GitLab 18.11.2 / 18.10.5 patch release. Earlier in the window, Anthropic's Claude became the default model in the Duo Agent Platform and a glab CLI surface launched for AI agents.

What is NATS?

NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.

NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.

GitLab leans into 'no training on your data' as the wedge against Atlassian and GitHub.

◆ Current state

GitLab's recent feed is heavy on positioning content rather than feature drops. The most pointed entry calls out Atlassian's August 2026 default-on data collection (and GitHub's Copilot data policy change) and stakes GitLab's counter-position: no training on customer data, regardless of tier. Around it: a UX research synthesis on agentic AI collaboration patterns across 17 platforms, security-team blog posts on threat intel and detection testing, and the routine GitLab 18.11.2 / 18.10.5 patch release. Earlier in the window, Anthropic's Claude became the default model in the Duo Agent Platform and a glab CLI surface launched for AI agents.

◆ Where it's heading

Two arcs. First, GitLab is using competitor governance changes — Atlassian's training opt-out, GitHub's Copilot policy — as a wedge to position itself as the safe place for enterprises that won't tolerate their code or content training a vendor's models. Second, the Duo platform is deepening with Claude as the default agent model and glab CLI as the structured tool surface, so when customers do adopt AI inside GitLab, the integration story is concrete.

◆ Prediction

Expect more comparative content as Atlassian's August 17 cutover approaches, paired with concrete tooling — likely an admin-facing 'data residency and training opt-out' control panel that lets GitLab Self-Managed and Dedicated customers point at the same guarantee. The Duo Agent Platform will likely add more first-class MCP-style integrations alongside Claude.

NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.

◆ Current state

NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.

◆ Where it's heading

The desired-state metalayer is an architectural addition that addresses a real operational risk: JetStream's previous behavior required careful sequencing of cluster topology changes to avoid data loss or inconsistent state. The pattern across recent releases — isolated stream read locks, constant-time removal from service maps, reduced client buffer flushing — shows a systematic performance and correctness pass across JetStream at high scale. NATS is moving toward the safety properties needed for production-critical stateful messaging.

◆ Prediction

v2.15.0 GA will likely ship within weeks of RC.2. The next cycle will probably extend desired-state semantics to more JetStream operations and potentially introduce observability tooling around reconciliation state, giving operators visibility into in-progress cluster changes.
