CircleCI vs Incus: at a glance
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.
What is Incus?
Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.

CircleCI
6.3INFRA · APIS
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.

5.0INFRA · APIS
Incus 7.6 fixes 18 security issues, eight critical, and adds SR-IOV NIC live migration
◆ Current state
Incus 7.6, released October 30, carries 18 security fixes, eight rated critical, many of them about restricted projects reaching the default project or the host, plus an authentication bypass through unverified client certificate chains. Its features aim at larger environments: live migration for VMs using SR-IOV NICs, multifd for VM live migration, cluster healing options, compression for block volumes, and OIDC opaque tokens. 7.5 before it added live migration between projects, cluster metrics and NVIDIA GPU cliques. The 7.0 LTS branch received a second patch, 7.0.2, with no described changes.
◆ Where it's heading
Live migration is still the through-line: 7.4 made it near-live for dependent disks, 7.5 took it across projects, and 7.6 extends it to VMs using SR-IOV NICs. The other thread is multi-tenancy under scrutiny. The size of the 7.6 security batch, with several critical items in project isolation, shows that restricted projects are now being tested as a real boundary, and the release adds a build and threat model for Anthropic's OSS Scanner.
◆ Prediction
Expect a 7.6.x patch or further security fixes, because the project-isolation findings cover a wide surface. The monthly feature cadence should continue with more live-migration throughput work, given multifd and the throughput improvements in this release.
