 ## [Unreleased]
 
+## [0.1.0] — 2026-06-12
+
+First beta release.
+
+### Fixed
+- `extra_vars` no longer leak across instances. Ansible's `load_extra_vars()`
+  memoizes its dict and `VariableManager` held it by reference, so
+  `update_extra_vars` / the `hostvars=` constructor path mutated process-global
+  state visible to every other instance. Each instance now copies its own
+  `extra_vars`.
+- `build_task` used `== True` for the legacy `module_ignore_errors` kwarg,
+  which wrongly accepted truthy non-bools like `1` (since `1 == True`). It now
+  uses `is True` so only the literal bool opts in.
+
 ### Changed
 - `__version__` is now derived from installed package metadata via
   `importlib.metadata` instead of a hardcoded string, so it stays in sync

+### Added
+- Variable-access API documentation and tests: `get_host_var` /
+  `get_visible_var`, `host_vars` / `visible_vars`, `extra_vars` /
+  `update_extra_vars`, covering host/group/extra precedence and template
+  rendering.
+- Edge-case test suite: cardinality/inventory errors, multi-task and
+  multi-host failure aggregation, unreachable hosts, `NoTasksError`, the
+  legacy `module_ignore_errors` kwarg, string-args guidance, and
+  `gather_facts`.
+- Tier-2 integration tests over a real SSH transport (`ssh` marker) against a
+  throwaway containerized sshd in `tests/ssh/`; auto-skips when no target is
+  configured. New `test-ssh` CI job runs them.

 A thin Python wrapper over Ansible's executor. Lets you run Ansible modules from Python with structured results, batch execution, and a host-object-first API — without going through `pytest-ansible` or `ansible-runner`.
 
-> **Status: alpha (0.1.0a0).** Built from a working internal implementation; API is stable in shape but may shift in details before 1.0.
