4.2.1 (2023.06.14)

• [Resolve #1344] Addressing issue with Generate hook and its deprecation (#1346) Here is what this includes:
  • The dump_template action ALSO triggers before_generate and after_generate
  • The generate action ALSO triggers before_dump_template and after_dump_template
  • The StackDiffer invokes dump_template rather than generate, preventing our own code from triggering deprecation warnings.
  • The documentation for hook points is updated to include all current hooks, including notes about the aliasing.
  • Deprecation of generate is removed after discussion in Slack. This deprecation would be too disruptive to many users, and we agreed instead to support a permanent alias of generate => dump_template.

• [Resolve #1263] Stack output caching
• [Resolve #1252] Supporting resolvers in Hook and Resolver arguments, with new !substitute, !join, !split, and !select resolvers!

Nonfunctional

• add a pre-commit linter to validate circleci configs

4.0.2 (2023.02.20)

Fixed

• [Resolve #1307] Fixing Connection Manager bug (#1308)

4.0.1 (2023.02.12)

Changed

• Supporting !rcmd resolver up to v2

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)

Changed

• [Resolve #1098] Deploy docker container to sceptreorg repo (#1265)

• [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.
