## API stability

Two major versions of fsnotify exist. 

**[fsnotify.v0](https://gopkg.in/fsnotify.v0)** is API-compatible with [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify). Bugfixes *may* be backported, but I recommend upgrading to v1.

```go
import "gopkg.in/fsnotify.v0"
```

\* Refer to the package as fsnotify (without the .v0 suffix).

**[fsnotify.v1](https://gopkg.in/fsnotify.v1)** provides [a new API](https://godoc.org/gopkg.in/fsnotify.v1) based on [this design document](http://goo.gl/MrYxyA). You can import v1 with:

```go
import "gopkg.in/fsnotify.v1"
```

Further API changes are [planned](https://github.com/go-fsnotify/fsnotify/milestones), but a new major revision will be tagged, so you can depend on the v1 API.

**Master** may have unreleased changes. Use it to test the very latest code or when [contributing][], but don't expect it to remain API-compatible:

```go
import "github.com/go-fsnotify/fsnotify"
```
