What is Harbor?

Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.

Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.

What is Node-RED?

Node-RED 5.0.9 lets users drag-order flows in the explorer and adds error badges to tabs.

Node-RED maintains two lines. 5.0.9 is a larger-than-usual maintenance release: flows can be drag-ordered in the Explorer sidebar, tabs and the explorer show error badges, HTML script and style blocks get JavaScript and CSS support, Monaco moves to 0.57, and CSV, Range, RBE, Filter and MQTT nodes get fixes. 4.1.17 backports only the merge-conflict resolution fixes.

Harbor 2.14.6 RC2 adds Go CVE fixes on top of the regression rollbacks.

◆ Current state

Harbor v2.14.6-rc2 keeps the rollbacks from RC1, so webhooks can reach private networks and legacy signer pulls are allowed by default, and adds Go dependency upgrades for High and Critical CVEs, Go 1.26.10, an actual byte limit in the CNAI parser to stop decompression attacks, and a nil-event panic fix in user audit. The 2.15 line got the same rollbacks in 2.15.4 RC1.

◆ Where it's heading

Harbor's recent releases are split between security hardening and undoing the parts of that hardening that broke real deployments. Both supported lines now carry the rollbacks, and new work is CVE fixes rather than features.

◆ Prediction

Expect 2.14.6 and 2.15.4 finals shortly; the entries don't show a 2.16 feature release yet.

5.0

Node-RED 5.0.9 lets users drag-order flows in the explorer and adds error badges to tabs.

◆ Current state

Node-RED maintains two lines. 5.0.9 is a larger-than-usual maintenance release: flows can be drag-ordered in the Explorer sidebar, tabs and the explorer show error badges, HTML script and style blocks get JavaScript and CSS support, Monaco moves to 0.57, and CSV, Range, RBE, Filter and MQTT nodes get fixes. 4.1.17 backports only the merge-conflict resolution fixes.

◆ Where it's heading

The 5.x line is now taking editor usability work from a wider set of contributors, with six first-time contributors in 5.0.9. The 4.1.x branch stays on backports only. The feed shows no 5.1 or new major feature yet.

◆ Prediction

Expect more 5.0.x releases with editor improvements; the entries don't show when a 5.1 with larger features will arrive.
