-After converting the top section from `X.Y.Z-beta.N (Unreleased)` to `X.Y.Z (YYYY-MM-DD)`, add a new `(Unreleased)` placeholder at the top using the **next minor version**, not the next patch:
-
-- If releasing a **patch** (`X.Y.Z` where `Z > 0`), the new placeholder is `X.(Y+1).0-beta.1 (Unreleased)`.
-- If releasing a **minor** (`X.Y.0`), the new placeholder is `X.(Y+1).0-beta.1 (Unreleased)`.
-
-Example: after releasing `1.24.1`, add `## 1.25.0-beta.1 (Unreleased)` at the top — not `## 1.24.2-beta.1`.
-
-This matches the behavior of `eng/scripts/Update-CliVersion.ps1`, which increments the minor version (not the patch) when creating the post-release development placeholder.
+Replace the top `X.Y.Z-beta.N (Unreleased)` section with `X.Y.Z (YYYY-MM-DD)`. Do not add a new
+`(Unreleased)` placeholder above the release entry: release-readiness checks require the first changelog
+entry to match `cli/version.txt`.

 # Release History
 
-## 1.35.0-beta.1 (Unreleased)
+## 1.34.2 (2026-09-23)
 
 ### Features Added
 
-### Breaking Changes
+- [[#9866]](https://github.com/Azure/azure-dev/pull/9866) Add dependency-aware `azd extension uninstall` that records why each extension was installed, blocks removing extensions other extensions depend on unless `--force` is used, and offers to remove dependencies that are no longer needed unless `--no-dependencies` is set.
+- [[#10049]](https://github.com/Azure/azure-dev/pull/10049) Add `Account.GetCurrentPrincipal` to the preview extension gRPC contract so extensions can read the current identity's object ID and principal type without decoding access tokens.
 
 ### Bugs Fixed
 
+- [[#10033]](https://github.com/Azure/azure-dev/pull/10033) Fix project-level `predeploy` and `postdeploy` hook output not being shown during `azd up`. Thanks @jongio for the contribution!
+- [[#10049]](https://github.com/Azure/azure-dev/pull/10049) Fix login details for system-assigned managed identities being reported as not logged in.
+
 ### Other Changes
 
+- [[#9866]](https://github.com/Azure/azure-dev/pull/9866) Update `azd extension show` to display compatibility, ownership, dependencies, and installed dependents. JSON output now uses camelCase keys and omits empty fields.
+- [[#10052]](https://github.com/Azure/azure-dev/pull/10052) Update the agentic `azd init` flow to report AI credits instead of premium requests.
+- [[#10061]](https://github.com/Azure/azure-dev/pull/10061) Update the `execution.environment` telemetry field to report `agency` when `azd` runs inside an Agency session.
+- [[#10095]](https://github.com/Azure/azure-dev/pull/10095) Update the published Homebrew casks to use Homebrew's declarative `postflight_steps`.
+- [[#10132]](https://github.com/Azure/azure-dev/pull/10132) Update the bundled GitHub CLI to v2.101.0.
