What is Tailscale?

Tailscale makes a device's public IP a posture check, after three client security patches.

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

5.0

Tailscale makes a device's public IP a posture check, after three client security patches.

◆ Current state

Tailscale is moving tailnet administration into policy and automation: MagicRoute, declarative node sharing, OAuth device provisioning and posture alerts all landed in October. The 1.104 client line underneath turned into a run of security patches, v1.104.2, v1.104.4 and v1.104.5, in under two weeks. November opened with the public IP address posture attribute going GA and the India relay servers moving from Bengaluru to Mumbai.

◆ Where it's heading

Device posture keeps gaining inputs: alerts and badges in October, now where a device connects from. Access rules are drifting from who you are toward what the device is and where it sits, all expressed in policy.

◆ Prediction

More posture attributes and posture-driven actions in the admin console look likely, given monitoring, alerts and now public IP shipped within a month.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.
