• Behavior change: removes the default ./.* ignore pattern, as it was often surprising and usually not needed with .gitignore handling.
• Add --no-default-ignore to explicitly disable all default ignores (@akerl)
• Restructured slightly to support being used as a library within other utilities (@passcod). Right now, this is mostly for cargo watch.

• POSIX: Add --signal option to specify signal to send to child process (@chr4)
• Add --no-shell option to exec() child process directly, instead of going through sh/cmd.exe (@chr4)
• Requires Rust 1.15 for building/Cargo installation

• Add -w/--watch option back to manually specify directories to watch. This is useful for cutting down on file descriptors used when watching deeply nested directory structures on Linux.
• Load .gitignore files from all watched directories, and then search upwards in the directory hierarchy for any additional ones that need to be loaded. When watching multiple directories with a common parent, .gitignore files will only be loaded once.
• Test all .gitignore files found for each notification from the outside in.

• Unix: reap children upon receipt of SIGCHLD
• Add -k option for sending SIGKILL to child processes

• Unix: Add -k option to send SIGKILL to child processes
• Unix: propagate SIGTSTP/SIGCONT signals (used when you hit control-z in your shell for job control)

• Drop --watch option, as it has confusing semantics around where to find .gitignore files. If you need it, file an issue.
• POSIX-based OSes: wait for all child processes to exit before running command
• Remove all features requiring nightly Rust builds
• Build size optimizations

• Fix infinite loop when no .gitignore file found
• Optimize filter matching
• Upgrade to notify 3

Automatically deployed release

• When waiting for all file system changes, de-dupe paths. This significantly reduces CPU for Linux users, as inotify sends a lot of notifications

• Windows: launch child processes in a new job object, letting us kill all subprocesses

• Add --run-initially flag
• Search for .gitignore files in parent dirs
• Set $WATCHEXEC_UPDATED_PATH to the first updated path
• Add --force-poll option
• macOS/Linux/BSD: launch child processes in their own process group

Initial release

• Load and use .gitignore file, if one is located in the current working directory

• Add -r option to restart commands when new changes arrive

• By default, watch the current directory and all subdirectories. Can be overridden with --watch
• New option: -e to monitor file extensions (e.g. -e js,html,css)
• Fix dotted dirs not being ignored by default
• Rename -d option to -v (verbose)

• Support -f for filter patterns, and -i for ignore patterns
• All arguments after directory to watch are interpreted as command to run
