Starting with v3.0.0, support for alexaSkill event without appId provided will be removed.
Starting with v3.0.0, extensions to nonexistent resources in resources.extensions will throw an error instead of passing silently.
Starting with v3.0.0, framework will unconditionally run service local installation of serverless if its found.
Starting with v2.0.0, globally installed CLI will by default run (fallback to) service local installation of serverless if it's found.
Adapt to this behavior now by adding enableLocalInstallationFallback: true to service configuration. Alternatively you may opt-out by setting it to false (note that'll be ineffective starting from v3.0.0, where support for this setting will be dropped, and CLI will unconditionally favor locally installed serverless installations when found)
provider.httpApi.timeout and functions[].events[].httpApi.timeout settings will no longer be recognized with v2.0.0.
Endpoints are configured to automatically follow timeout setting as configured on functions (with extra margin needed to process HTTP request on AWS side)
Support for slss command will be removed with v2.0.0. Use sls or serverless instead.
maximumEventAge and maximumRetryAttempts should be defined directly at function level. Support for those settings on destinations level, will be removed with v2.0.0
Default HTTP API Payload version will be switched to 2.0 with next major release (For more details see payload format documentation)
Configure httpApi.payload explicitly to ensure seamless migration.
Support for Node.js v6 and v8 will be dropped with v2.0.0 release
Ensure to rely on at least Node.js v10 (It's recommended to use LTS version, as listed at https://nodejs.org/en/)
Please use onUnauthenticatedRequest instead. allowUnauthenticated will be removed with v2.0.0
Please use bin/serverless.js instead. bin/serverless will be removed with v2.0.0
Plase use provider.kmsKeyArn and functions[].kmsKeyArn. service.awsKmsKeyArn and functions[].awsKmsKeyArn will be removed with v3.0.0
