+## [Unreleased]
+
+### Removed
+
+- **GLPI 9.x is no longer listed as supported.** The README and docs claimed
+  "9.1 and later" (one page said "tested on 9.x"), but no 9.x release was ever
+  tested and the official `glpi/glpi` images start at 10.0. Supported: GLPI
+  10.0, 11.x and 12.x; the High-Level API clients need 11.0.6+.
+
+### Added
+
+- **Integration tests against real GLPI in CI** (`tests/integration`,
+  `.github/workflows/integration.yaml`): both clients, sync and async, against
+  the latest patch of `glpi/glpi:10.0`, `11.0` and `12.0` on every pull request
+  and weekly. Each bug fixed in 1.5.0 has a test that fails on the old
+  behaviour. Skipped locally unless `GLPI_IT_URL` is set.
+- **DCO sign-off required on contributions** (`DCO`, `dco` CI check).
+- **Lint and type checks in CI:** `ruff check` (rules in `ruff.toml`) and
+  `mypy --strict`, pinned versions; the code base is clean on both.

 Beta, actively maintained. Releases follow [semantic versioning](https://semver.org/) and every change is listed in the [CHANGELOG](https://github.com/giovanny07/python-glpi-utils/blob/main/CHANGELOG.md). The legacy clients are the most stable part. The OAuth2 clients follow GLPI's High-Level API, which is still evolving, and their behaviour changed in 1.4 and 1.5.
 
-Tested in CI on Python 3.9 to 3.13 with mocked HTTP. Tested by hand against real servers for 1.5.0 (2026-10-13): GLPI 10.0.28 (legacy API), 11.0.9 and 12.0.0 (legacy API, High-Level API 2.3 and 3.0). Older GLPI 9.x and 10.x releases are expected to work with the legacy clients but are not tested.
+Unit tests run in CI on Python 3.9 to 3.13. Integration tests run both clients, sync and async, against official `glpi/glpi` containers: the latest patch of GLPI 10.0 (legacy API), 11.0 and 12.0 (legacy API and every High-Level API version the server offers), on every pull request and weekly. GLPI 9.x is not supported.
