+# Changelog
+
+All notable changes to vSphere-MCP-Pro will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [0.2.0] - 2025-12-23
+
+### Added
+
+- **`VsphereApiError` exception class** - Custom exception with rich error context including:
+  - HTTP status code
+  - vCenter error type extraction (supports both `/api` and `/rest` response formats)
+  - Human-readable error messages from vCenter
+  - Convenience properties: `is_not_found`, `is_unauthorized`, `is_forbidden`, `is_conflict`
+
+- **`VsphereClientPool` class** - Thread-safe connection pooling:
+  - Maintains one authenticated session per vCenter host
+  - Automatic session reuse to prevent vCenter session exhaustion
+  - `atexit` hook for graceful cleanup on process termination
+  - `get()`, `remove()`, `close_all()` methods
+  - `size` and `hosts` properties for observability
+
+- **`VsphereClient.logout()` method** - Properly terminates vCenter sessions via DELETE to session endpoint
+
+- **`VsphereClient.close()` method** - Calls `logout()` then closes the underlying `requests.Session`
+
+- **`VsphereClient.host` property** - Clean accessor for the configured hostname
+
+- **`VsphereClient.is_authenticated` property** - Check if session token is present
+
+- **Response validation** - All API methods now validate responses via `_check_response()`:
+  - Raises `VsphereApiError` on non-2xx responses
+  - Supports `allow_statuses` for operations like DELETE that return 204
+  - Descriptive error messages include operation context
+
+- **Helper methods in `VsphereClient`**:
+  - `_safe_json()` - Safely parse JSON responses without raising
+  - `_check_response()` - Validate HTTP response and raise on error
+  - `_extract_value()` - Handle `/api` vs `/rest` response format differences
+
+### Changed
+
+- **Fixed decorator pattern in `server.py`** - Converted `inject` from broken function to proper decorator factory:
+  ```python
+  # Before (broken - caused TypeError)
+  @inject
+  def list_vms(...): ...
+  
+  # After (working)
+  @inject("list_vms")
+  def list_vms(...): ...
+  ```
+
+- **Destructive operations now properly flagged** - Added `destructive=True` to:
+  - `delete_vm`
+  - `delete_vm_snapshot`
+  - `modify_vm_resources`
+
+- **Session management refactored** - Replaced per-request client creation with `VsphereClientPool`:
+  - Single pool instance created in `build_server()`
+  - Pool injected into all tools via `_pool` parameter
+  - Significantly reduces vCenter session consumption
+
+- **Improved error messages** - API errors now include full context:
+  ```
+  VsphereApiError: Failed to get VM 'vm-999': HTTP 404 on /api/vcenter/vm/vm-999 [NOT_FOUND]: The VM was not found.
+  ```
+
+### Fixed
+
+- **Dockerfile path error** - Changed `COPY src /app/src` to `COPY vsphere_mcp_pro /app/vsphere_mcp_pro`
+
+- **Session leak** - Previous implementation created new session per API call without logout; now properly pooled and cleaned up
+
+- **Silent API failures** - Methods previously returned error JSON as if successful; now raise `VsphereApiError`
+
+### Deprecated
+
+- None
+
+### Removed
+
+- `client_for()` helper function in `server.py` - Replaced by `VsphereClientPool.get()`
+
+### Security
+
+- Sessions are now properly terminated on shutdown via `atexit` hook
+- Reduced attack surface by limiting active vCenter sessions
+
+## [0.1.0] - Initial Release
+
+### Added
+
+- Initial MCP server implementation for VMware vCenter 8.0+
+- VM lifecycle management (power on/off/reset, delete)
+- Snapshot operations (list, create, delete)
+- Inventory discovery (VMs, hosts, datastores, networks, datacenters)
+- Resource modification (CPU, memory)
+- Token-based RBAC authorization
+- Token bucket rate limiting
+- JSONL audit logging
+- SSL verification with optional CA bundle
+- Allowed-host enforcement
+- Support for both `/api` and `/rest` vCenter endpoints
