What is Certbot?

Certbot 5.10 closes a webroot race that could change the wrong file's permissions.

Certbot 5.10.0 fixes a race in the webroot plugin: if a less privileged user could modify the webroot while Certbot ran, Certbot could change the ownership and mode of an unintended file. It also rejects ARI renewal windows whose end is not after their start. 5.9.0 in October fixed renewal hooks being told failed SANs had renewed.

What is Chromatic?

Chromatic opens a beta that lets coding agents read and fix visual test failures.

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

5.0

Certbot 5.10 closes a webroot race that could change the wrong file's permissions.

◆ Current state

Certbot 5.10.0 fixes a race in the webroot plugin: if a less privileged user could modify the webroot while Certbot ran, Certbot could change the ownership and mode of an unintended file. It also rejects ARI renewal windows whose end is not after their start. 5.9.0 in October fixed renewal hooks being told failed SANs had renewed.

◆ Where it's heading

Certbot is in maintenance mode, with monthly releases focused on correctness and safety around renewals. The last feature step was IP address certificates in 5.3 and 5.4; since then the work has been consolidation and fixes.

◆ Prediction

More small releases around renewals, ARI handling and plugin safety are likely; the entries show no new feature direction.

Chromatic

7.5

Chromatic opens a beta that lets coding agents read and fix visual test failures.

◆ Current state

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

◆ Where it's heading

Chromatic is turning from a review screen for humans into a feedback loop that coding agents can act on. Each new entry point (Vitest, React Native, now agents) widens who and what sends work through its visual tests.

◆ Prediction

The beta post is brief, so how agents connect is unclear; expect a follow-up naming the supported agents and moving this toward general availability.
