Reviewed all PRs merged on 2026-06-24 and 2026-06-25. Added one new entry in the Bugs Fixed section for PR #8776 — the macOS Homebrew trust fix.

The other merged PRs were either:

• Merged to a feature branch (huimiu/foundry-azure-yaml), not main (feat: complete Foundry azure.yaml unification (sibling targets, endpoint reuse) #8783, feat: generalize $ref resolver + shared $ref-aware azure.yaml edit helper #8777, feat(agents): secure-by-default private networking via azure.yaml #8708, feat(agents): split Foundry init into per-resource azure.yaml services #8675)
• Extension-specific with its own CHANGELOG (azure.ai.skills fixes in fix(azure.ai.skills): address follow-up items from skill commands PR #8791)
• CI/testing infrastructure only (Add PR gate tests for azd ai agent extension #8754 PR gate tests)

Verified the new entry added since my last review:

• #8776 (Homebrew trust fix): PR is merged, description accurately reflects the change, format is consistent with other entries.

All 12 changelog entries now reference valid, merged PRs. Version files (version.txt and version.go) remain in sync at 1.26.0. Next unreleased section (1.27.0-beta.1) is properly templated.

Resolved — merged main into the branch and resolved the CHANGELOG.md conflict in commit 9b58000. The conflict arose because origin/main had added #8776 to the 1.27.0-beta.1 (Unreleased) section; the resolution keeps #8776 under 1.26.0 and leaves the next unreleased placeholder empty.

Incremental review (1 new commit since my last look): merge commit resolving the CHANGELOG conflicts I flagged earlier.

Verified:

• version.txt, version.go, and CHANGELOG heading all read 1.26.0
• All 12 referenced PRs (#8424, #8599, #8649, #8656, #8666, #8679, #8681, #8697, #8704, #8725, #8776, #8785) are merged
• Next unreleased section (1.27.0-beta.1) is properly templated
• CI is green, no conflicts remaining
