v2.0.0

Features

• Polling no longer uses fs.watchFile but polls the directory directly
• add ignored option
• add followSymlinks option
• allow all Iterables instead of only Array passes as arguments
• Changed API to take an options object
  • Old API is also accepted without warning (it may be deprecated in the next major)
• emit remove event when files or directories are not found during initial scan
  • It's assumed that they are removed between reading and watching start
• add watching of missing items
• Support /RegExp/ for ignored option
• limit maximum number of os watchers on OSX to 2000 and on windows to 10000
  • limit can be changed with WATCHPACK_WATCHER_LIMIT environment variable
  • once limit is reached watchers are merged into recursive watchers
• merge multiple os watchers from watchers with different options into one os watcher
• add logging of recursive watchers when WATCHPACK_RECURSIVE_WATCHER_LOGGING env var is set

Bugfixes

• Normalize readdir result to NFC
• Skip watching the root of the filesystem as file even when requested
• use options identify instead of stringified options to merge watchers
• removals and changes in the aggregated event no longer both contain a file
• aggregateTimeout: 0 now works correctly
• don't fire change events when files are only read
• fix handling of renames that only change the casing of files on a case-insensitive filesystem

Performance

• avoid calling process.nextTick when unneeded on watcher creation
• cache time entry map in Watcher
• close watchers faster
• avoid an unneeded filter call

Dependencies

• remove neo-async dependency to be smaller

Contributing

• added prettier
• node 14 in CI
• test watcher limit of 1 on CI

Changes

• increase minimum node.js version to 10
• initial scan do not fire change events when no start time is provided
• improve polling schedule to not try to poll faster than the scanning
