AdGuard Home vs cert-manager: at a glance
What is AdGuard Home?
AdGuard Home's stable line takes a Go security update and turns off Multipath TCP.
AdGuard Home v0.107.80 is a security release on the stable line: it moves to the Go version with the 1.27.3 fixes, disables Multipath TCP support to avoid CVE-2026-98432, and drops macOS 13 Ventura as a consequence of Go 1.27. The beta channel moved to the new UI and v1.0.0 numbering at the end of September, with v1.0.0-b.1 as the first build.
What is cert-manager?
cert-manager's 1.21 line is about failure handling: backoff caps, renewal policies and clearer auth errors
cert-manager is running the 1.21 pre-release train through alpha.0, alpha.1 and now beta.0. The changes cluster around what happens when certificate issuance goes wrong: a configurable cap on CertificateRequest retry backoff, a new AuthFailed issuer condition that separates bad Venafi credentials from transient infrastructure failures, and certificate renewal policies.

AdGuard Home
2.5INFRA · APIS
AdGuard Home's stable line takes a Go security update and turns off Multipath TCP.
◆ Current state
AdGuard Home v0.107.80 is a security release on the stable line: it moves to the Go version with the 1.27.3 fixes, disables Multipath TCP support to avoid CVE-2026-98432, and drops macOS 13 Ventura as a consequence of Go 1.27. The beta channel moved to the new UI and v1.0.0 numbering at the end of September, with v1.0.0-b.1 as the first build.
◆ Where it's heading
Two tracks run in parallel: a stable 0.107 line that ships mostly security and dependency updates, and a beta line that has become v1.0.0 and carries the new UI. Platform support is now set by Go's own requirements, as the macOS 13 removal shows on both lines.
◆ Prediction
The next visible moves are likely further v1.0.0 betas and continued 0.107 security releases; the entries do not show when 1.0 reaches stable.

0.0INFRA · APIS
cert-manager's 1.21 line is about failure handling: backoff caps, renewal policies and clearer auth errors
◆ Current state
cert-manager is running the 1.21 pre-release train through alpha.0, alpha.1 and now beta.0. The changes cluster around what happens when certificate issuance goes wrong: a configurable cap on CertificateRequest retry backoff, a new AuthFailed issuer condition that separates bad Venafi credentials from transient infrastructure failures, and certificate renewal policies.
◆ Where it's heading
This is a reliability and observability cycle rather than a feature cycle. The recurring theme is making cert-manager's failure states legible — distinguishing permanent from transient errors, bounding retry storms, and letting Helm's common labels propagate into the ACME solver resources it creates on the fly. CAInjectorMerging reaching GA and deprecated API removal point to a line that is consolidating.
◆ Prediction
Expect a 1.21.0 release candidate next, with the renewal policy work being the piece most likely to change shape before it stabilises.
