This release primarily removes old or unnecessary dependencies. Future releases will continue to replace dependencies that have more modern equivalents.

Fix

• SnappyStream initialization race condition. (#353)
• IPv6 address support (#352)
• Support JavaScript String objects as messages (#341)
• Removed debug.destroy

Deprecated

Versions older than node 12.13.0.

Changes

• Debug is now a dev dependency
• SnappyStream upgraded to 2.0 using new rust bindings for snappy
• Replaced BigNumber.js with built-in BigInt
• Replaced request.js with node-fetch
• Removed async.js dependency.

• Upgrade snappystream to support NodeJS 12
• Upgrade other dependencies

New

• Added "ready" and "not_ready" events for Reader.

Improved

• Lazy deserialization of messages
• Cached Backoff Timer calculations

Fix

• Support NodeJS 10
• Fix Snappy issues with NSQD 1.0 and 1.1
• Fix close behavior for Readers
• Fix short timeout for connection IDENTIFY requests. (Thanks @emaincourt)

Memory leak due to lookupd polling. A debug.js instance wasn't cleaned up when a new NSQDConnection instance was instantiated for discovered nsqd servers. The more frequent the polling, the worse the problem.

• Fix maxAttempts behavior
• Fix default requeueDelay

Both of these changes are subtle and might impact existing behavior. maxAttempts will allow an additional attempt before automatically finishing and discarding a message when set. requeueDelay by default will be the intended 90 seconds instead of 90 milliseconds.

• Refactored Reader connect.
• Cleanup intervals that prevented a clean exit of the NodeJS process.
• Fix to ensure all connections were closed when close was called.

• Breaking change: Node versions 6 and greater supported from now on.
• Support for deferred message publishing! (thanks @spruce)
• Added idleTimeout for Reader and Writer (thanks @abbshr)
• Snappy support is now optional. (thanks @bcoe)
• Snappy support is now fixed and working with 1.0.0-compat!
• Fixed backoff behavior if mulitiple messages fail at the same time. Should recover much faster.
• Use TCP NO_DELAY for nsqd connections.
• Chores:
  • Replaced underscore with lodash
  • Move src to lib
  • Dropped Babel support
  • Use Standard JS style
  • Less flakey tests

• De-dupe on broadcast address
• Support the 1.0 compatible format for lookupd. This will break old versions of support for nsqd.

• Fixes npm install warnings
• Fixes security issues in dependencies
