Serverless: Deprecation warning: CLI options definitions were upgraded with "type"

I’m using
Node v10.17.0
NPM 6.11.3

My serverless framework info is the following:

Framework Core: 2.43.0
Plugin: 5.1.3
SDK: 4.2.2
Components: 3.10.0

My serverless.yml file has the following:

     # NOTE: update this with your service name
service: notes-api

# Create an optimized package for our functions
package:
  individually: true

plugins:
  - serverless-bundle # Package our functions with Webpack
  - serverless-offline
  - serverless-dotenv-plugin # Load .env as environment variables

provider:
  name: aws
  runtime: nodejs10.x
  stage: dev
  region: ap-southeast-1
  # To load environment variables externally
  # rename env.example to .env and uncomment
  # the following line. Also, make sure to not
  # commit your .env.
  #
  #environment:
  #  SAMPLE_ENV_VAR: ${env:SAMPLE_ENV_VAR}

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: hello
          method: get

My package json looks like this:

{
  "name": "notes-api",
  "version": "2.2.0",
  "description": "A Node.js starter for Serverless Framework with ES6 and TypeScript support",
  "main": "handler.js",
  "scripts": {
    "test": "serverless-bundle test"
  },
  "author": "",
  "license": "MIT",
  "repository": {
    "type": "git",
    "url": "https://github.com/AnomalyInnovations/serverless-nodejs-starter.git"
  },
  "devDependencies": {
    "aws-sdk": "^2.912.0",
    "serverless-bundle": "4.3.1",
    "serverless-dotenv-plugin": "^2.1.1",
    "serverless-offline": "^5.3.3"
  },
  "dependencies": {
    "uuid": "^8.3.2"
  }
}

This is based on the tutorial at serverless-stack.com

Whenever i run any command: i get the following error:

eprecation warning: CLI options definitions were upgraded with “type” property (which could be one of “string”, “boolean”, “multiple”). Below listed plugins do not predefine type for introduced options:
- ServerlessPlugin for “out”

Please report this issue in plugin issue tracker.
Starting with next major release, this will be communicated with a thrown error.

Serverless: Deprecation warning: Resolution of lambda version hashes was improved with better algorithm, which will be used in next major release.
Switch to it now by setting “provider.lambdaHashingVersion” to “20201221”

I really wish error messages were more human. Does anyone know what this means?
