========================================
1. Backward Incompatible Changes
========================================

- Publisher:
  - All the `Publisher`'s are now `abstract` classes
  - `__construct` no longer accepts adapter, define `setupAdapter` instead
  - `setupAdapter` is new method that set-up's the adapter instead of constructor
  - `__wakeup` and `__sleep` are now defined on `AbstractPublisher` for serialization

========================================
2. New Features
========================================

Will now keep track of changes in UPGRADING document.

New `Serialized` idea is a worker/queue/publisher that wrap messages from other publishers, currently
this is used to reliably delay long tasts (i.e. something to be scheduled in two weeks), and is used together
with new `DynamoSQS` adapter that saves jobs to AWS DynamoDB and once jobs are ready (TTL triggers) they end up
in SQS queue (DynamoDB->DynamoDB Stream->Lambda->SQS) where they are picked up by worker.
`DynamoSQS` uses DynamoDB for saving and SQS for picking jobs.

- Publisher:
  - New `Serialized` publisher
- Workers:
  - New `Serialized` worker
  - New `Closure`    worker
- Message
  - New `Serialized` message
- Adapter
  - New `DynamoSQS` adapter

========================================
3. Deprecated Functionality
========================================

`Nsq` adapter is no longer maintaned as it's performance is too low. The benefit it has is built-in dashboard
and status of queues. You can continue using it as is.

`toggleDebug()` is removed on workers, they now use standard PSR logger, by default with NORMAL verbose level and
output to console

`debug()` is removed on workers, replaced with `logDebug()`

========================================
4. Performance Improvements
========================================

Refactored internal worker generator loop for handling of empty loops, this affects the APNS worker directly
and possibly others.
Recommended PHP version 7.2 or 7.3.
