v2.0.15

• process.on('unhandledRejection'): allow to catch promise error that have not been catched
• upgrade fclone and pidusage (faster windows CPU/Mem monitoring)
• allow to call pm2 CLI from bash script managed by pm2
• #2394 fix pm2 id command
• #2385 ts-node upgraded to latest
• #2381 autocompletion fix

2.0.12 Bradbury

• Memory usage reduced by 40%
• CPU usage in overall situations reduced by 60%
• Refined pm2 logs command with --json, --format and --raw options
• Faster process management with CONCURRENT_ACTIONs enabled
• Faster installation (v1: ~30secs, v2: ~10secs)
• Faster pm2 update with Keymetrics linking delayed at the end
• Much better Module system with raw NPM feedback
• Better Windows support
• pm2-docker command with his official Docker image + json output + auto exit
• rundev (pm2-dev) command enhanced (better log output, post-exec cmd)
• Watch and Reload instead of Watch and Restart
• New PM2 API, backward compatible with previous PM2 versions

The new PM2 API is greatly tested and well designed:

var PM2 = require('pm2');

// Or instanciate a custom PM2 instance

var pm2 = new PM2.custom({
  pm2_home :    // Default is the legacy $USER/.pm2. Now you can override this value
  cwd      :    // Move to CWD,
  daemon_mode : // Should the process stay attached to this application,
  independant : // Create new random instance available for current session
  secret_key  : // Keymetrics secret key
  public_key  : // Keymetrics public key
  machine_name: // Keymetrics instance name
});

// Start an app
pm2.start('myapp.js');

// Start an app with options
pm2.start({
  script   : 'api.js',
  instances: 4
}, function(err, processes) {
});

// Stop all apps
pm2.stop('all');

// Bus system to detect events
pm2.launchBus((err, bus) => {
  bus.on('log:out', (message) => {
    console.log(message);
  });

  bus.on('log:err', (message) => {
    console.log(message);
  });
});

// Connect to different keymetrics bucket
pm2.interact(opts, cb)

// PM2 auto closes connection if no processing is done but manually:

pm2.disconnect(cb) // Close connection with current pm2 instance
pm2.destroy(cb)    // Close and delete all pm2 related files of this session

• Better CLI/API code structure
• PM2 isolation for multi PM2 instance management

1.1.2

• [#2071 #2075] Fix pm2-dev command

Galactica

This release is about PM2's internals refactoring, homogenization in action commands (in terms of behavior and outputs). Some interesting features has been added, as YAML file support (for application declaration) and better support for other languages (Python,Perl...). The Keymetrics agent has been enhanced, dividing by two the memory usage and avoiding any possible leak in any potential scenarios. Reconnection system has been refactored too.

Keymetrics users: a lot of benefits brought to you to do this upgrade

This version has been heavily tested in testing, production environments and deeply monitored in terms of CPU and Memory usage. Tests have been hardened.

• [#133 #1568] Allow to rename a process via pm2 restart app --name "new-name"
• [#2002 #1921 #1366] Fix CLI/JSON arguments update on restart (args, node_args, name, max-memory)
• [#578] Add YAML support for application configuration file (in extent to JSON and JSON5 support)
• [Keymetrics agent refactoring] TCP wait, memory consumption divided by two, reconnection refactoring, keep alive ping system
• [Keymetrics agent refactoring] Fix random no response from pm2 link and pm2 unlink
• [#2061] Kill ESRCH of processes in cluster mode with SIGINT catcher fixed
• [#2012 #1650 #1743] CLI/JSON arguments update on reload
• [#1613] Reload all reload ALL applications (stopped, errored...)
• [#1961] Fix kill timeout info log
• [#1987] Fix FreeBSD startup script
• [#2011] Respect process.stdout/.stderr signature
• [#1602] Fix zombie process when using babel-node as interpreter
• [#1283] --skip-env option to not merge update with system env
• Homogeneize actions commands outputs
• Option --interpreter-args added (alias of node-args)
• Allow to use exactly the same option in JSON declaration and CLI (e.g. interpreter) to avoid confusion
• pm2 show, now shows more commands to manage processes
• Refactor programmatic system

Update procedure

PM2 CLI and internals have been frozen since the 0.14 version, so updating PM2 is totally seamless:

$ npm install pm2 -g
$ pm2 update
