Looks great. Looks like it was something we should have done all along.

Unfortunately our integration tests tend to fail when they're run concurrently and there's already some integration tests I already have running. However, I'll trigger the tests probably either later this afternoon or tomorrow morning. Assuming those pass, I'm happy with this change.

Releasing v4.0.0 (#1292)
b8d6319 
## 4.0.0 (2023.02.08)

### Added
 - [Resolve #1283] Introducing `sceptre_role`, `cloudformation_service_role` (#1295)
   - These are just iam_role and role_arn renamed to be a lot clearer. See "Deprecations" below.


### Changed
 - [Resolve #1299] Making the ConnectionManager a more "friendly" interface for hooks, resolvers,
   and template handlers (#1287, #1300)
   - This creates adds the public `get_session()` and
     `create_session_environment_variables()` methods to make AWS interactions
     easier and more consistent with individual stack configurations for
     iam_role, profile, and region configurations.
   - The `call()` method now properly distinguishes between default stack
     configurations for profile, region, and `sceptre_role` and setting those to
     `None` to nullify them.
 - Preventing Duplicate Deprecation Warnings from being emitted (#1297)

#### _Potentially_ Breaking Changes
 - The !cmd hook now invokes the passed command using the AWS environment
   variables that correspond with the stack's IAM configurations (i.e. iam_role,
   profile, region). This means that the hook will operate the same as every
   other part of Sceptre and regard how the stack is configured. This should make
   it easier to invoke other tools like AWS CLI with your hooks. However, if
   your project is setting environment variables with the intent to change how
   the command authenticates with AWS (such as a different token, profile, or
   region), these environment variables will be overridden. To maintain the same
   functionality, you should prefix your command with
   `export AWS_SESSION_TOKEN={{environment_variable.AWS_SESSION_TOKEN}} &&` (or
   whatever other environment variable(s) you need to explicitly set).

### Deprecations
 - [Resolve #1283] Deprecating `iam_role`, `role_arn`, and `template_path` (#1295)
   - `iam_role` and `role_arn` have been aliased to `sceptre_role` and
      `cloudformation_service_role`. Using these fields will result in a
      DeprecationWarning.
   - `template_path` has actually been slated for removal since v2.7. `template`
      should be used instead. Using `template_path` will result in a
      DeprecationWarning.
   - All three deprecated StackConfig fields will be removed in v5.0.0.

## 3.3.0 (2023.02.06)

### Added
 - [Resolve #1261] Add coloured differ (#1260)
   - Implements coloured diffs for the diff (difflib) command. Responds to --no-color.
 - [Resolves #1271] Extend stack colourer to include "IMPORT" states (#1272)
 - [Resolves #1179] cloudformation disable-rollback option (#1282)
   - Allow user to disable a cloudformation rollback on a sceptre deployment.

### Changed
 - [Resolve #1098] Deploy docker container to sceptreorg repo (#1265)
   - Deploy sceptre docker images to dockerhub sceptreorg repo instead of cloudreach repo
 - Updating Setuptools and wheel versions to avert security issues
 - [Resolve #1293] Improve the Stack Config Jinja Syntax Error Message to include the Stack Name (#1294)
 - [Resolves #1267] Improve the Stack Config Jinja Error Message to include the Stack Name (#1269)

### Fixed
 - [Resolve #1273] Events start from response time (#1275)
   - Resolves #1273 by starting event filtering from the timestamp returned in
     the AWS response headers rather than relying on the workstation clock.
 - [Resolve #1253] Failed downloads raise error (#1277)
   - Throwing an informative error when the template fails to download instead
     of passing the error message to CloudFormation.
 - [Resolves #1179] Changed disable-rollback default to None (#1288)
   - We want the default value to be None to represent "Do whatever's configured
     in the StackConfig" and True/False will override the StackConfig.

### Nonfunctional
 - Add tweet-release to CircleCI config (#1259)
 - [Resolves #1276] Adopt Black Auto-formatter (#1278)
   - Reformatting all Python files using the Black code formatter. This also
     delivers a new function for generating `__repr__` methods which was needed
     to deal with a line-too-long issue in Template. Per discussion in #1276 this
     PR also disables E203 in flake8.
 - Update sceptre-circleci docker image (#1284)
   - Update to build and test with a docker image that's based on the official
     circleci python docker image.
 - [Resolve #1264] Updating the CDK docs to point to the new sceptre-cdk-handler
   (#1285)
   - This updates our docs to no longer reference the old CDK approach (which
     didn't work with CDK assets). In its place, it references the new
     sceptre-cdk-handler package that covers that functionality.
