### Instrumenting Jobs with Heartbeats

Source: https://docs.sentry.io/platforms/ruby/crons

```ruby
# Create a config from a crontab schedule (every 10 minutes)
monitor_config = Sentry::Cron::MonitorConfig.from_crontab(
  '5 * * * *',
  checkin_margin: 5, # Optional check-in margin in minutes
  max_runtime: 15, # Optional max runtime in minutes
  timezone: 'Europe/Vienna', # Optional timezone
)

# Create a config from an interval schedule (every 10 minutes)
monitor_config = Sentry::Cron::MonitorConfig.from_interval(
  10,
  :minute,
  checkin_margin: 5, # Optional check-in margin in minutes
  max_runtime: 15, # Optional max runtime in minutes
  timezone: 'Europe/Vienna', # Optional timezone
)
```

--------------------------------

### Added Configuration Options

Source: https://docs.sentry.io/platforms/ruby/guides/delayed_job/migration

New configuration options available for transport customization and background worker management.

```ruby
# this behaves similar to the old config.scheme option
config.transport.transport_class = MyTransportClass

# sentry-ruby sends events asynchronously with its own background workers
# the default number of workers equals to your machine's processor count
# you can adjust the number with
config.background_worker_threads = 10

# to send events synchronously like sentry-raven does, set it to 0
config.background_worker_threads = 0
```
