gulp changelog

4.0.0

Task system changes

• replaced 3.x task system (orchestrator) with new task system (bach)
  • removed gulp.reset
  • removed 3 argument syntax for gulp.task
  • gulp.task should only be used when you will call the task with the CLI
  • added gulp.series and gulp.parallel methods for composing tasks. Everything must use these now.
  • added single argument syntax for gulp.task which allows a named function to be used as the name of the task and task function.
  • added gulp.tree method for retrieving the task tree. Pass { deep: true } for an archy compatible node list.
  • added gulp.registry for setting custom registries.

CLI changes

• split CLI out into a module if you want to save bandwidth/disk space. you can install the gulp CLI using either npm install gulp -g or npm install gulp-cli -g, where gulp-cli is the smaller one (no module code included)
• add --tasks-json flag to CLI to dump the whole tree out for other tools to consume
• added --verify flag to check the dependencies in package.json against the plugin blacklist.

vinyl/vinyl-fs changes

• added gulp.symlink which functions exactly like gulp.dest, but symlinks instead.
• added dirMode param to gulp.dest and gulp.symlink which allows better control over the mode of the destination folder that is created.
• globs passed to gulp.src will be evaluated in order, which means this is possible gulp.src(['*.js', '!b*.js', 'bad.js']) (exclude every JS file that starts with a b except bad.js)
• performance for gulp.src has improved massively
  • gulp.src(['**/*', '!b.js']) will no longer eat CPU since negations happen during walking now
• added since option to gulp.src which lets you only match files that have been modified since a certain date (for incremental builds)
• fixed gulp.src not following symlinks
• added overwrite option to gulp.dest which allows you to enable or disable overwriting of existing files

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
