What is Nautobot?

Nautobot 3.3 alpha 2 adds test helpers and a cable location filter after 3.2.9's token-leak fix.

Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks; on November 9 v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys. The 3.3 feature line opened the same day with REST API rate limiting and JSON and YAML exports. v3.3.0a2 on November 13 mostly adds Playwright helpers for App test suites, along with a location filter on the cable connection form and a fix for a login page that reloaded every 15 seconds.

What is Pacemaker?

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

Nautobot 3.3 alpha 2 adds test helpers and a cable location filter after 3.2.9's token-leak fix.

◆ Current state

Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks; on November 9 v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys. The 3.3 feature line opened the same day with REST API rate limiting and JSON and YAML exports. v3.3.0a2 on November 13 mostly adds Playwright helpers for App test suites, along with a location filter on the cable connection form and a fix for a login page that reloaded every 15 seconds.

◆ Where it's heading

3.3 is moving through alphas quickly, four days apart, while the security audit continues on the stable lines. The Playwright helpers suggest Nautobot wants App developers to test against its UI with shared tooling rather than custom scripts.

◆ Prediction

More 3.3 alphas or a beta should follow within weeks, alongside the next pair of 3.2.x and 2.4.x security releases on the two-week rhythm.

6.3

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

◆ Current state

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

◆ Where it's heading

The cluster's internal transport is being rebuilt on the assumption that the network between nodes is not trusted. Authentication and encryption arrived first, and the fixes that followed, overflow guards and a maximum remote message size, are the hardening pass on the same code paths. Release discipline is heavy and visible: each version ships a release candidate with an identical commit set days earlier, and every 3.0 release documents the regressions it introduced and where they were fixed.

◆ Prediction

Remote CIB operations now support both X509 certificates and PSK, and the recent fixes all sit in message framing and size limits; further work is most likely to continue in that message-handling code rather than adding another authentication mechanism.
