Release Notes

terraform-ibm-modules/terraform-ibm-landing-zone (terraform-ibm-modules/landing-zone/ibm)

### [`v4.4.3`](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/releases/tag/v4.4.3) [Compare Source](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/compare/v4.4.2...v4.4.3) ##### Bug Fixes - updated the optional `mfa` attribute in the `iam_account_settings` variable to a string type. It was incorrectly expecting a number. (#​[https://github.com/terraform-ibm-modules/terraform-ibm-landing-zone/issues/488](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/issues/488)es/488)) ([5f9792f](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/commit/5f9792f57274966f4807eb378d7ba814d13328a8)) ### [`v4.4.2`](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/releases/tag/v4.4.2) [Compare Source](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/compare/v4.4.1...v4.4.2) ##### Bug Fixes - updated the default Teleport image to `ibm-ubuntu-22-04-2-minimal-amd64-1` as old default image (`ibm-ubuntu-22-04-1-minimal-amd64-4`) is now deprecated. NOTE: If upgrading from an older version to this version, terraform will not attempt to update the image currently being used so that you don't inadvertently create an outage or lose data (#​[https://github.com/terraform-ibm-modules/terraform-ibm-landing-zone/issues/493](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/issues/493)es/493)) ([ff6417c](https://togithub.com/terraform-ibm-modules/terraform-ibm-landing-zone/commit/ff6417c68db3c25c2b3f621d5a1071192d0a836e))
