## [Unreleased]

Nothing yet.

## [1.6.0] - 2022-10-13

This version of fsnotify needs Go 1.16 (this was already the case since 1.5.1,
but not documented). It also increases the minimum Linux version to 2.6.32.

### Additions

- all: add `Event.Has()` and `Op.Has()` ([#477])

  This makes checking events a lot easier; for example:

	    if event.Op&Write == Write && !(event.Op&Remove == Remove) {
	    }

	Becomes:

	    if event.Has(Write) && !event.Has(Remove) {
	    }

- all: add cmd/fsnotify ([#463])

  A command-line utility for testing and some examples.

### Changes and fixes

- inotify: don't ignore events for files that don't exist ([#260], [#470])

  Previously the inotify watcher would call `os.Lstat()` to check if a file
  still exists before emitting events.

  This was inconsistent with other platforms and resulted in inconsistent event
  reporting (e.g. when a file is quickly removed and re-created), and generally
  a source of confusion. It was added in 2013 to fix a memory leak that no
  longer exists.

- all: return `ErrNonExistentWatch` when `Remove()` is called on a path that's
  not watched ([#460])

- inotify: replace epoll() with non-blocking inotify ([#434])

  Non-blocking inotify was not generally available at the time this library was
  written in 2014, but now it is. As a result, the minimum Linux version is
  bumped from 2.6.27 to 2.6.32. This hugely simplifies the code and is faster.

- kqueue: don't check for events every 100ms ([#480])

  The watcher would wake up every 100ms, even when there was nothing to do. Now
  it waits until there is something to do.

- macos: retry opening files on EINTR ([#475])

- kqueue: skip unreadable files ([#479])

  kqueue requires a file descriptor for every file in a directory; this would
  fail if a file was unreadable by the current user. Now these files are simply
  skipped.

- windows: fix renaming a watched directory if the parent is also watched ([#370])

- windows: increase buffer size from 4K to 64K ([#485])

- windows: close file handle on Remove() ([#288])

- kqueue: put pathname in the error if watching a file fails ([#471])

- inotify, windows: calling Close() more than once could race ([#465])

- kqueue: improve Close() performance ([#233])

- all: various documentation additions and clarifications.
