terraform/CHANGELOG.md at 627a2121b856fe36239f85050a620dcf378a6091

0.15.0 (Unreleased)

UPGRADE NOTES:

config: The list and map functions, both of which were deprecated since Terraform v0.12, are now removed. You can replace uses of these functions with tolist([...]) and tomap({...}) respectively. [GH-26818]
cli: Interrupting execution will now cause terraform to exit with a non-0 status. [GH-26738]
backend/atlas: the atlas backend, which was deprecated since v0.12, has been removed. [GH-26651]
backend/gcs: The path config argument, which was deprecated since v0.11, has been removed. Use the prefix argument instead. [GH-26841]

ENHANCEMENTS:

config: Terraform will now emit a warning if you declare a backend block in a non-root module. Terraform has always ignored such declarations, but previously did so silently. This is a warning rather than an error only because it is sometimes convenient to temporarily use a root module as if it were a child module in order to test or debug its behavior separately from its main backend. [GH-26954]
cli: Improved support for Windows console UI on Windows 10, including bold colors and underline for HCL diagnostics. [GH-26588]
cli: The family of error messages with the summary "Invalid for_each argument" will now include some additional context about which external values contributed to the result. [GH-26747]
cli: Typing an invalid top-level command, like terraform destory instead of destroy, will now print out a specific error message about the command being invalid, rather than just printing out the usual help directory. [GH-26967]
cli: Plugin crashes will now be reported with more detail, pointing out the plugin name and the method call along with the stack trace [GH-26694]
provisioner/remote-exec: Can now run in a mode that expects the remote system to be running Windows and excuting commands using the Windows command interpreter, rather than a Unix-style shell. Specify the target_platform as "windows" in the connection block. [GH-26865]

BUG FIXES:

cli: Exit with an error if unable to gather input from the UI. For example, this may happen when running in a non-interactive environment but without -input=false. Previously Terraform would interpret these errors as empty strings, which could be confusing. [GH-26509]
cli: TF_LOG levels other than trace will now work correctly [GH-26632]
cli: Core and Provider logs can now be enabled separately for debugging, using TF_LOG_CORE and TF_LOG_PROVIDER [GH-26685]
