 ## Unreleased
 
-- Nothing yet.
+## v1.4.9 - 2026-05-07
+
+- Added Remote-mode image routing: image requests now use the proven Lingma IPC image pipeline instead of sending local/data URLs directly to the remote chat endpoint.
+- Added mixed image + tool handling: the proxy extracts image context through IPC, then returns to Remote API native tool calling so clients still receive proper `tool_calls` / `tool_use`.
+- Fixed multi-turn image follow-ups by reusing the most recent user image from request history when the latest user turn says things like "continue based on the previous image".
+- Improved Remote API tool compatibility by forwarding structured messages, tool definitions, tool choice, and native remote tool-call deltas instead of prompt-emulating tools in Remote mode.
+- Added regression tests for remote structured tools, image routing, image-context injection, and previous-turn image reuse.
+- Verified the production desktop app launch path from `/Applications/Lingma Proxy.app`, including pure image, multi-turn image, and image + forced tool-call requests.
+
+## v1.4.8 - 2026-05-06
+
+- Fixed Remote API base URL auto-detection so Lingma OSS/static asset hosts are rejected and cannot be used as API endpoints.
+- Improved Remote API model-list 404 errors with a clear hint to manually set the official or enterprise remote API domain.
+- Restored desktop input editing shortcuts by using the native Wails edit menu, fixing copy, paste, cut, undo, redo, and select-all in app input fields.
+- Added regression tests for Windows/Lingma log URL parsing, missing leading `h` repair, and OSS-host rejection.
+
+## v1.4.7 - 2026-05-06
+
+- Renamed user-facing product, desktop app, release assets, and documentation from Lingma IPC Proxy to Lingma Proxy.
+- Clarified that Remote API mode is the recommended default and that only IPC plugin mode is based on the `coolxll/lingma-ipc-proxy` protocol discovery.
+- Added `lingma-proxy.json` and `~/.config/lingma-proxy/config.json` config lookup/write paths while keeping legacy `lingma-ipc-proxy` config fallback.
+- Added a desktop top-bar force quit button that stops the proxy and exits the app on macOS and Windows.
+- Added Anthropic `/v1/messages/count_tokens` compatibility for Claude Code v2.1.129+.
+- Reduced prompt-emulated tool loops by allowing final answers after tool results and dropping tool calls with missing required arguments.
+- Prevented hosted Anthropic `web_search` from being short-circuited again after a `tool_result` follow-up.
+- Changed the default proxy request timeout to `0`, meaning no proxy-level per-request deadline. Positive timeout values still enable timeout-triggered remote fallback.
+
+## v1.4.6 - 2026-05-06
+
+- Added the VS Code Lingma plugin shared cache directory `~/.lingma/vscode/sharedClientCache` to remote credential auto-detection.
+- This fixes Windows setups where Lingma is installed through the VS Code extension and stores `cache/user` plus `cache/id` under the plugin shared client cache.
+
+## v1.4.5 - 2026-05-06
+
+- Improved Windows remote credential detection for Lingma App installations.
+- Remote API mode now checks `cache/user` before machine-id lookup so missing-login errors are more accurate.
+- Expanded machine-id discovery to recursive Lingma app logs and VS Code Lingma plugin logs instead of only `logs/lingma.log`.
+- Added support for additional machine-id log formats such as `machine_id`, `machineId`, and JSON-style fields.

+Lingma Proxy exposes Tongyi Lingma as standard **OpenAI-compatible** and **Anthropic-compatible** HTTP APIs. It can use either the recommended Remote API backend or the local IDE plugin IPC channel, and ships as both a CLI proxy service and a cross-platform desktop app for macOS and Windows.
 
 The project is designed for tools such as Claude Code, Cline, Continue, OpenCode, custom agents, and any client that can talk to OpenAI or Anthropic style APIs.
 
 The proxy now supports two backend modes:
 
-- **Remote API mode (default, experimental)**: imports the local Lingma login cache or an explicit credential file and calls Lingma remote APIs directly. This feels more like an official API, does not depend on an IDE IPC session, and is currently the recommended mode for Claude Code / Hermes style agents.
+- **Remote API mode (default, recommended)**: imports the local Lingma login cache or an explicit credential file and calls Lingma remote APIs directly. This behaves closest to a normal hosted API, avoids IDE/plugin session and environment limits, and is currently the best mode for Claude Code / Hermes style agents.
-- **IPC plugin mode**: connects to the local Lingma IDE plugin over WebSocket / Named Pipe. This keeps behavior closest to the IDE plugin and is useful as a compatibility fallback.
+- **IPC plugin mode**: connects to the local Lingma IDE plugin over WebSocket / Named Pipe. This keeps behavior closest to the IDE plugin, but it can inherit IDE session lifetime, local plugin state, and environment constraints, so it is mainly a compatibility fallback.

 Notes:
 
+- Remote API mode is the recommended default for day-to-day agent usage. It bypasses the IDE/plugin IPC runtime, so it is less affected by plugin session state, IDE working directory, or local extension environment limitations.
 - Remote mode does not write or migrate login state. It only reads the local Lingma cache or the credential file you provide.
 - If your Lingma plugin uses a dedicated domain, remote mode first uses `--remote-base-url`, `LINGMA_REMOTE_BASE_URL`, or the JSON config field. If those are empty, it scans Lingma's local logs on macOS, Windows, and Linux for endpoint hints such as `endpoint config:` and marketplace service URLs.
 - The desktop Settings page shows the resolved remote domain and detection source without exposing tokens.
 - `/v1/models` in remote mode returns remote API model keys, which may not match the IPC plugin display IDs such as `MiniMax-M2.7` or `Kimi-K2.6`.
+- Image requests in remote mode are routed through the IPC image pipeline because the direct remote chat endpoint ignores local `file://` and data URL image payloads. If a request also contains tools, Lingma Proxy first extracts image context through IPC and then sends the tool-capable turn through Remote API native tool calling.
 - Local validation passed `/health`, `/v1/models`, OpenAI streaming/non-streaming chat, and Claude Code Anthropic + Bash tool use. Claude Code full tool runs are much slower than simple OpenAI requests because the client sends a large context and performs a second tool-result turn.
 - This mode is inspired by the remote API and credential-signing research in [ZipperCode/lingma2api](https://github.com/ZipperCode/lingma2api), integrated here as a switchable backend under the existing OpenAI / Anthropic / desktop app architecture.

+### Server Deployment Without CI
+
+For Linux servers where you do not want to cross-compile locally, check in `vendor/` and let the target host build from source:
+
+```bash
+go mod vendor
+REMOTE_HOST=150.158.105.6 \
+REMOTE_USER=root \
+REMOTE_PASSWORD='your-password' \
+./scripts/deploy-remote.sh
+```
+
+The script uploads `cmd/`, `internal/`, `vendor/`, `go.mod`, and `go.sum`, prepares a Docker build context on the server, then rebuilds the runtime image there with a multi-stage Docker build. The remote host needs `docker`, `tar`, and `curl`; it does not need a host Go installation, but it does need network access to pull the base Docker images if they are not already cached.
+
+### API Authentication
+
+Set one or more API keys with `LINGMA_PROXY_API_KEYS` or the JSON config field `api_keys`:
+
+```bash
+export LINGMA_PROXY_API_KEYS="key-one,key-two"
+go run ./cmd/lingma-ipc-proxy --host 127.0.0.1 --port 8095
+```
+
+```json
+{
+  "api_keys": ["key-one", "key-two"]
+}
+```
+
+The deployment script also passes through `LINGMA_PROXY_API_KEYS`, so the same key set can be enabled on the remote server during deploy.
+
+When keys are configured, all API endpoints except `/`, `/health`, `/runtime/status`, and `/v1/runtime/status` require authentication. Clients can send either:
+
+- `Authorization: Bearer <key>`
+- `x-api-key: <key>`
+
+This works well with OpenAI-compatible clients that already expose an API key field.

-This project is based on the protocol insight and initial discovery work from [coolxll/lingma-ipc-proxy](https://github.com/coolxll/lingma-ipc-proxy). The core idea of connecting to Lingma's private local IPC protocol and exposing standard API endpoints came from that project. This fork extends the implementation with broader OpenAI/Anthropic compatibility, tool emulation, image handling, desktop app support, request/log inspection, cross-platform packaging, and release automation.
+The **IPC plugin mode** is based on the protocol insight and initial discovery work from [coolxll/lingma-ipc-proxy](https://github.com/coolxll/lingma-ipc-proxy). That project first demonstrated that Lingma's private local IPC protocol can be bridged to standard HTTP API endpoints. Lingma Proxy keeps that IPC path as a compatibility backend and extends it with broader OpenAI/Anthropic compatibility, tool emulation, image handling, desktop app support, request/log inspection, cross-platform packaging, and release automation. The default **Remote API mode** is a separate backend that calls Lingma remote APIs directly and is documented independently above.

 - 远端模式不会写入或迁移你的登录态，只会读取本机 Lingma 缓存或你指定的凭据文件。
 - 如果 Lingma 插件配置过专属域名，远端模式会优先使用 `--remote-base-url`、`LINGMA_REMOTE_BASE_URL` 或配置文件；这些为空时，会扫描 macOS、Windows、Linux 上 Lingma 本地日志里的 `endpoint config:`、Marketplace service URL 等线索。
 - 桌面端设置页会展示当前解析到的远端域名和来源，但不会展示 token / key 明文。
 - 远端模式的 `/v1/models` 返回的是远端接口模型 key，不一定等同于 IPC 插件模式里看到的 `MiniMax-M2.7`、`Kimi-K2.6` 等展示名。
+- 远端模式下的图片请求会自动走 IPC 图片链路，因为直连远端聊天接口不会直接消费本地 `file://` 和 data URL 图片。若请求同时带工具，代理会先通过 IPC 提取图片上下文，再把不含图片但包含上下文的请求交给 Remote API 原生工具调用。
 - 当前本机实测：`/health`、`/v1/models`、OpenAI 流式 / 非流式、Claude Code Anthropic + Bash 工具调用均可用；Claude Code 完整工具链耗时明显高于简单 OpenAI 请求。

+REMOTE_HOST=150.158.105.6 \
+REMOTE_USER=root \
+REMOTE_PASSWORD='your-password' \
+./scripts/deploy-remote.sh
+```
+
+脚本会上传 `cmd/`、`internal/`、`vendor/`、`go.mod` 和 `go.sum`，在服务器上准备 Docker 构建上下文，然后用多阶段 Docker build 重建运行时镜像。远端主机需要预装 `docker`、`tar`、`curl`；不需要额外安装宿主机 Go，但如果相关基础镜像未缓存，仍需要能拉取 Docker 基础镜像。
+
+### API 鉴权
+
+可以通过环境变量 `LINGMA_PROXY_API_KEYS` 或 JSON 配置里的 `api_keys` 设置一个或多个 API Key：
+
+```bash
+export LINGMA_PROXY_API_KEYS="key-one,key-two"
+go run ./cmd/lingma-ipc-proxy --host 127.0.0.1 --port 8095
+```
+
+```json
+{
+  "api_keys": ["key-one", "key-two"]
+}
+```
+
+部署脚本也会透传 `LINGMA_PROXY_API_KEYS`，所以可以在远端部署时一起启用同一组 key。
+
+配置了 key 之后，除 `/`、`/health`、`/runtime/status`、`/v1/runtime/status` 之外的接口都会要求鉴权。客户端可以使用：
+
+- `Authorization: Bearer <key>`
+- `x-api-key: <key>`
+
+这也兼容大多数 OpenAI 兼容客户端自带的 API Key 配置方式。

+
+This document will attempt to explain how this code works. 
+
+## Windows COM 
+
+Windows makes heavy use of it's [COM api](https://en.wikipedia.org/wiki/Component_Object_Model), 
+(Component Object Model) which is a binary interface - allowing programs that agree on a memory 
+layout in order to communicate. 
+
+COM apis are typically Object Oriented, and based on interfaces. This should be familiar to Go
+programmers, since Go includes interfaces as a core part of its language design and type system.  
+
+The difference being that in COM we don't get any runtime help, nice syntax or type safety. We
+get raw [VTables](https://en.wikipedia.org/wiki/Virtual_method_table) and deal with raw memory. 
+
+You can think of COM as like working with a Go api that uses `any` (empty interface) _everywhere_
+and typeswitching is required to access methods `file, ok := obj.(File)`.  
+
+Some languages like C++ have extensions that support COM and provide convenient wrappers for
+generating and using COM apis. Go does not. C also, does not. 
+
+However there is a package `go-ole` that allows us to _call_ COM apis with some level of 
+convenience - which we will use where possible. What go-ole does not expose is a way to 
+implement a COM object in Go. 
+
+## Interacting with COM objects in pure Go
+
+In order to interact with COM objects we need to:
+
+1. locate headers containing the VTable definitions
+2. define vtables in Go that are compatable with those definitions
+3. invoke the appropriate COM objects using our vtables and the syscall package  
+
+### 1. locate headers 
+
+Download Windows SDK via the [Visual Studio installer](https://visualstudio.microsoft.com/downloads). 
+You will need to check "Desktop development with C++".
+
+Once complete you can navigate to the SDK include directory.
+
+In our case we needed `Windows.ui.notifications.h`, which contains the definitions of
+the types we want to call, and `NotificationActivationCallback.h` which contains the definition of
+`INotificationActivationCallback` which is the interface we need to _implement_.
+
+### 2. define vtables in Go
+
+The VTables are defined in C (mired in macros). We need to define compatible vtables in Go syntax
+so we can call the ones defined in the header. 
+
+COM objects are structured in a such a way that we want a parent struct who's first field is a pointer
+to the vtable struct. A full example is provided later, for now it we need something like this:
+
+```go
+type Object struct {
+  lpvtbl *ObjectVtbl
+}
+type ObjectVtbl struct {
+  MethodOne uintptr
+  MethdoTwo uintptr
+  //...
+}
+```
+
+### 3. invoke methods in Go 
+
+Using package `syscall` we can invoke these methods (provided the uintptr are valid) using
+`syscal.SyscallN`. Paramters and return values are defined in the C headers. 
+
+```go
+func (v *Object) One() error {
+  hr, _, _ := syscall.SyscallN(uintptr(v))
+  if hr != ole.S_OK {
+    return ole.NewError(hr)
+  }
+  return nil
+}
+```
+
+With that we can inoke methods on a COM object. This is how `go-ole` works. 
+
+## Implementing a COM object in pure Go (no cgo!)
+
+To do this we will need to allocate raw memory for the VTables (so that Go garbage collector
+doesn't interfere) and write our function pointers to the VTables. 
+
+Since these are not safe Go capabilities we will need the help of package `syscall` (on Windows). 
+
+Package `syscall` provides two very important functions:
+
+1. `NewProc` - which loads a function from a DLL 
+2. `NewCallback` - which allocates a C-callable function pointer from a Go function
+
+For the first part, we can load the Windows kernel api via `kernel32.dll` system dll, and
+pull out `GlobalAlloc` and `GlobalFree` using `syscall.NewProc`. 
+
+For the second part, we can use `syscall.NewCallback` to build a C-callable function pointer 
+from a Go function and instantiate the VtTables with it. Caveat emptor: memory allocated by
+`NewCallback` is never released, and only 1024 callbacks are guaranteed to be allowed. This
+is why we only allocate the callbacks once on init.
+
+Thus we can implement a COM object (invokable from C) like this:
+
+```go
+
+// Initialize our kernel functions. 
+var (
+  kernel32   = windows.NewLazySystemDLL("kernel32.dll")
+  procMalloc = kernel32.NewProc("GlobalAlloc")
+  procFree   = kernel32.NewProc("GlobalFree")
+)
+
+// malloc allocates raw memory using the Windows kernel.
+// In case of out of memory, the returned pointer will be nil.
+// The memory is zeroed out to make sure we don't get garbage that looks like
+// valid Go data types.
+func malloc(size uintptr) unsafe.Pointer {
+	hr, _, _ := procMalloc.Call(uintptr(GMEM_FIXED|GMEM_ZEROINIT), uintptr(size))
+	if hr == 0 {
+		return nil
+	}
+	return unsafe.Pointer(hr)
+}
+
+// free deallocates raw memory allocated by malloc.
+func free(object unsafe.Pointer) {
+	procFree.Call(uintptr(object))
+}
+
+// Object defines our object. 
+// This is how COM objects are laid out in memory, where the first field is a pointer
+// to a vtable, and the vtable's fields are pointers to functions. 
+type Object struct {
+  lpvtbl *ObjectVtbl // lpvtbl is a COM conventional name for this field. 
+}
+
+// ObjectVtbl defines the Vtable of our object. 
+type ObjectVtbl struct {
+  MethodOne   uintptr
+  MethodTwo   uintptr
+  MethodThree uintptr
+}
+
+// These methods are allocated once as package globals because Go will never reclaim the
+// memory allocated for such callbacks. 
+// 
+// All arguments must be uintptr sized, and the return must be a uintptr as well. 
+// 
+// By convention, the first parameter is a pointer to the parent object. 
+var (
+  methodOne = syscall.NewCallback(func(this *Object) uintptr {
+    fmt.Printf("methodOne invoked\n")
+    return uintptr(0)
+  })
+  
+  methodTwo = syscall.NewCallback(func(this *Object) uintptr {
+    fmt.Printf("methodTwo invoked\n")
+    return uintptr(0)
+  })
+  
+  methodThree = syscall.NewCallback(func(this *Object) uintptr {
+    fmt.Printf("methodThree invoked\n")
+    return uintptr(0)
+  })
+)
+
+
+func NewObject() *Object {
+  // Allocate the parent object and the vtable. 
+  obj := (*Object)(malloc(unsafe.Sizeof(Object{})))
+  vtbl := (*ObjectVtbl)(malloc(unsafe.Sizeof(ObjectVtbl{})))
+
+  // Initialize the vtable with our static callback implementations. 
+  vtbl.MethodOne = methodOne
+  vtbl.MethodTwo = methodTwo
+  vtbl.MethodThree = methodThree
+  
+  // The returned object must be freed by GlobalFree. 
+  object.lpvtbl = vtbl
+  return obj
+}
+```
+
+## WinRT and Toast Notifications
+
+For this package the vtables we need are located in various headers `Windows.ui.notifications.h` and
+`NotificationActivationCallback.h` and `combase.h`.
+
+With all of the vtables replicated in Go as explained above we now need to interact with the Windows
+Runtime. 
+
+First we need to initialize the Windows Runtime with `RoInitialize`. 
+
+```go
+ole.RoInitialize(0)
+```
+
+Traditional COM uses GUIDs to identify objects and interfaces. WinRT uses strings (mapped to GUIDS 
+at runtime).
+
+To instantiate a WinRT COM object we invoke `RoGetActivationFactory` with the class string along with
+the interface GUID we expect to use. 
+
+
+```go
+CLSID_ToastNotification := "Windows.UI.Notifications.ToastNotification"
+IID_IToastNotificationFactory := ole.NewGUID("{50AC103F-D235-4598-BBEF-98FE4D1A3AD4}")
+
+factoryObject, err := ole.RoGetActivationFactory(CLSID_ToastNotification, IID_ToastNotificationFactory)
+if err != nil {
+	return nil, fmt.Errorf("getting activation factory: %w", err)
+}
+```
+
+From there we can unsafe cast to our callback definition (ole doesn't provide direct access to the methods).
+
+```go
+factory := (*IToastNotificationFactory)(unsafe.Pointer(factoryObject))
+notification, err := factory.CreateToastNotification(xml)
+```
+
+Repeat this process per object we need to instantiate. 
+
+To generate a toast notification from XML with a callback we need to instantiate several COM objects:
+
+1. `INotificationActivationCallback` our implementation to be invoked by the runtime 
+1. `ClassFactory` which can instantiate our `INotificationActivationCallback` implementation
+1. `XmlDocument` to contain the xml content of the notification
+1. `XmlDocumentIO` to provide an IO interface to the xml document (so we can write the xml to it)
+1. `Notification` specifying the content of the notification
+1. `Notifier` for showing notifications
+
+Finally we register our class factory using `CoRegisterClassObject` so the runtime can call us back
+and then we invoke `Notifier.Show` passing in the `Notification` object to display the notification. 
+
+In addition to calling and implementing COM objects we need to manipulate registry state to tell the 
+Windows Runtime metadata about our application. 
+
+1. register a CLSID (GUID) for our INotificationActivationCallback; this is how the runtime knows
+what object to ask for
+2. optionally provide an icon and an activation executable to be invoked when our application is not running
+
+
+With all of that correctly configured we can generate toast notifications on Windows in pure Go!

+# go-toast
+
+This package implements Windows toast notifications using the Windows Runtime COM API. 
+
+The XML schema used to describe such notifications is here: 
+
+https://learn.microsoft.com/en-us/windows/apps/design/shell/tiles-and-notifications/adaptive-interactive-toasts
+
+Package `wintoast` offers a lower-level api.
+Package `toast` offers a higher-level wrapper. 
+
+`wintoast` uses build tags to guard Windows only code. It will still compile on 
+non-Windows platforms, however the functions are stubbed out and will do nothing 
+when invoked. 
+
+## Usage
+
+### Basic
+
+```go
+noti := toast.Notification{
+    AppID: "My cool app",
+    Title: "Title",
+    Body: "Body",
+}
+
+err := noti.Push()
+```
+
+### Actions / Inputs with Callback
+
+Additionally, we can respond to notification activation with a callback. 
+
+```go
+// Set the callback that receives the data from the notification.
+// Any data from actions or inputs will be accessible here. 
+toast.SetActivationCallback(func(args string, data []UserData) {
+    fmt.Printf("args: %q, data: %v\n", args, data)
+})
+
+n := toast.Notification{
+    AppID: "My cool app",
+    Title: "Title",
+    Body: "Body", 
+}
+
+n.Inputs = append(n.Inputs, toast.Input{
+	ID:          "reply-to:john-doe",
+	Title:       "Reply",
+	Placeholder: "Reply to John Doe",
+})
+
+n.Inputs = append(n.Inputs, toast.Input{
+	ID:          "select-action",
+	Title:       "Selection Action",
+	Placeholder: "Pick an action to perform",
+	Selections: []toast.InputSelection{
+		{
+			ID:      "1",
+			Content: "do thing one",
+		},
+		{
+			ID:      "2",
+			Content: "do thing two",
+		},
+		{
+			ID:      "3",
+			Content: "do thing three",
+		},
+	},
+})
+
+n.Actions = append(n.Actions, toast.Action{
+	Type:      toast.Foreground,
+	Content:   "Send",
+	Arguments: "send",
+})
+
+n.Actions = append(n.Actions, toast.Action{
+	Type:      toast.Foreground,
+	Content:   "Close",
+	Arguments: "close",
+})
+
+err := n.Push()
+```

+//
+// Then, if you want in-process callback to be invoked upon user interaction,
+// invoke SetActivationCallback.
+//
+// Finally, generate your notification by instantiation a toast.Notification
+// and pushing it with Push method.

+//
+// The toast notification data. The following fields are strongly recommended;
+//   - AppID
+//   - Title
+//
+// If no toastAudio is provided, then the toast notification will be silent.
+//
+// The AppID is shown beneath the toast message (in certain cases), and above the notification within the Action
+// Center - and is used to group your notifications together. It is recommended that you provide a "pretty"
+// name for your app, and not something like "com.example.MyApp". It can be ellided if the value has already
+// been set via SetAppData.
+//
+// If no Title is provided, but a Body is, the body will display as the toast notification's title -
+// which is a slightly different font style (heavier).
+//
+// The Icon should be an absolute path to the icon (as the toast is invoked from a temporary path on the user's
+// system, not the working directory).
+//
+// If you would like the toast to call an external process/open a webpage, then you can set ActivationArguments
+// to the uri you would like to trigger when the toast is clicked. For example: "https://google.com" would open
+// the Google homepage when the user clicks the toast notification.
+// By default, clicking the toast just hides/dismisses it.

+# go-winio [![Build Status](https://github.com/microsoft/go-winio/actions/workflows/ci.yml/badge.svg)](https://github.com/microsoft/go-winio/actions/workflows/ci.yml)
+
+This repository contains utilities for efficiently performing Win32 IO operations in
+Go. Currently, this is focused on accessing named pipes and other file handles, and
+for using named pipes as a net transport.
+
+This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
+to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
+newer operating systems. This is similar to the implementation of network sockets in Go's net
+package.
+
+Please see the LICENSE file for licensing information.
+
+## Contributing
+
+This project welcomes contributions and suggestions.
+Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
+you have the right to, and actually do, grant us the rights to use your contribution.
+For details, visit [Microsoft CLA](https://cla.microsoft.com).
+
+When you submit a pull request, a CLA-bot will automatically determine whether you need to
+provide a CLA and decorate the PR appropriately (e.g., label, comment).
+Simply follow the instructions provided by the bot.
+You will only need to do this once across all repos using our CLA.
+
+Additionally, the pull request pipeline requires the following steps to be performed before
+mergining.
+
+### Code Sign-Off
+
+We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
+to certify they either authored the work themselves or otherwise have permission to use it in this project.
+
+A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
+
+Please see [the developer certificate](https://developercertificate.org) for more info,
+as well as to make sure that you can attest to the rules listed.
+Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run ./...
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+
+This can be done for the entire repo:
+
+```shell
+> go generate ./...
+```

+# Version 1.x.x
+
+* **Add more test cases and reference new test COM server project.** (Placeholder for future additions)
+
+# Version 1.2.0-alphaX
+
+**Minimum supported version is now Go 1.4. Go 1.1 support is deprecated, but should still build.**
+
+ * Added CI configuration for Travis-CI and AppVeyor.
+ * Added test InterfaceID and ClassID for the COM Test Server project.
+ * Added more inline documentation (#83).
+ * Added IEnumVARIANT implementation (#88).
+ * Added IEnumVARIANT test cases (#99, #100, #101).
+ * Added support for retrieving `time.Time` from VARIANT (#92).
+ * Added test case for IUnknown (#64).
+ * Added test case for IDispatch (#64).
+ * Added test cases for scalar variants (#64, #76).
+
+# Version 1.1.1
+
+ * Fixes for Linux build.
+ * Fixes for Windows build.
+
+# Version 1.1.0
+
+The change to provide building on all platforms is a new feature. The increase in minor version reflects that and allows those who wish to stay on 1.0.x to continue to do so. Support for 1.0.x will be limited to bug fixes.
+
+ * Move GUID out of variables.go into its own file to make new documentation available.
+ * Move OleError out of ole.go into its own file to make new documentation available.
+ * Add documentation to utility functions.
+ * Add documentation to variant receiver functions.
+ * Add documentation to ole structures.
+ * Make variant available to other systems outside of Windows.
+ * Make OLE structures available to other systems outside of Windows.
+
+## New Features
+
+ * Library should now be built on all platforms supported by Go. Library will NOOP on any platform that is not Windows.
+ * More functions are now documented and available on godoc.org.
+
+# Version 1.0.1
+
+ 1. Fix package references from repository location change.
+
+# Version 1.0.0
+
+This version is stable enough for use. The COM API is still incomplete, but provides enough functionality for accessing COM servers using IDispatch interface.
+
+There is no changelog for this version. Check commits for history.

+# Go OLE
+
+[![Build status](https://ci.appveyor.com/api/projects/status/qr0u2sf7q43us9fj?svg=true)](https://ci.appveyor.com/project/jacobsantos/go-ole-jgs28)
+[![Build Status](https://travis-ci.org/go-ole/go-ole.svg?branch=master)](https://travis-ci.org/go-ole/go-ole)
+[![GoDoc](https://godoc.org/github.com/go-ole/go-ole?status.svg)](https://godoc.org/github.com/go-ole/go-ole)
+
+Go bindings for Windows COM using shared libraries instead of cgo.
+
+By Yasuhiro Matsumoto.
+
+## Install
+
+To experiment with go-ole, you can just compile and run the example program:
+
+```
+go get github.com/go-ole/go-ole
+cd /path/to/go-ole/
+go test
+
+cd /path/to/go-ole/example/excel
+go run excel.go
+```
+
+## Continuous Integration
+
+Continuous integration configuration has been added for both Travis-CI and AppVeyor. You will have to add these to your own account for your fork in order for it to run.
+
+**Travis-CI**
+
+Travis-CI was added to check builds on Linux to ensure that `go get` works when cross building. Currently, Travis-CI is not used to test cross-building, but this may be changed in the future. It is also not currently possible to test the library on Linux, since COM API is specific to Windows and it is not currently possible to run a COM server on Linux or even connect to a remote COM server.
+
+**AppVeyor**
+
+AppVeyor is used to build on Windows using the (in-development) test COM server. It is currently only used to test the build and ensure that the code works on Windows. It will be used to register a COM server and then run the test cases based on the test COM server.
+
+The tests currently do run and do pass and this should be maintained with commits.
+
+## Versioning
+
+Go OLE uses [semantic versioning](http://semver.org) for version numbers, which is similar to the version contract of the Go language. Which means that the major version will always maintain backwards compatibility with minor versions. Minor versions will only add new additions and changes. Fixes will always be in patch. 
+
+This contract should allow you to upgrade to new minor and patch versions without breakage or modifications to your existing code. Leave a ticket, if there is breakage, so that it could be fixed.
