We want to start work on releasing Laconia v2.

Scope

The main breaking change to address is the upgrade to AWS SDK v3 for all of the laconia packages (excluding laconia-core):

• Upgrade to aws-sdk v3 #508

As part of this, we also want to take the opportunity to do the following:

• Remove aws-sdk from core #539
  Remove S3, SNS and the other built-in AWS dependencies from laconia-core.
• DynamoDB reader is using dynamoDbParams against documentClient #147
  As part of the v3 upgrade, we should make this change, to properly reflect the name of this parameter, especially since we're switching the underlying library.
• Remove callback support #538
  Remove the non-recommended legacy syntax for callback handler functions. This adds a lot of complexity to the core that we could remove by making LACONIA_NO_CALLBACK='true' the default behaviour.

These are all breaking changes, and therefore it would be good to get them done in a single 2.0.0 release.

Nice to haves:

• feat: allow extensions of LaconiaContext and Error types #814
• Register instance dependency #392
• Support 'batch' event in laconia-batch #2
• Pre-commit Prettier hook #545

Approach

There's a new v2 branch, which I will set as the default branch this week, with the plan to merge this back into master once we have a stable release.

Release checklist

• Mark v2 as main branch until features are built
• Update CHANGELOG
• Add documentation about upgrading from v1 to v2
• Use semantic-release to automate release process
• Mark master as the main branch after 2.0.0 release
