IMPROVEMENTS:

The filemd5, filesha1, etc functions from Terraform v0.12 are backported primarily to allow writing
modules that can work in both Terraform 0.11 and 0.12, since the sha1(file("...")) pattern in 0.12
works only for files containing valid UTF-8 text; sha1file("...") must be used instead. Both
forms are equivalent in Terraform 0.11.
backend/remote: Retry calls when the remote backend responds with a server error (#20589)
backend/remote: Check for external updates while waiting for user input (#20622)

BUG FIXES:

backend/remote: Fix "token too long" errors when streaming remote operation logs (#20241)
backend/remote: Use the can-queue-apply permission to detect if apply is allowed (#20462)
backend/remote: Exit with 1 when a remote run is canceled (#20482)
core: Use slashes in the module manifest to prevent Windows/Linux compatibility issues (#20246)

This is a pre-release version of Terraform v0.12.0.

For important information on the status of this release, please see the release announcement.

BACKWARDS INCOMPATIBILITIES / NOTES:

backend/s3: workspace_key_prefix can no longer be defined with leading or trailing slashes. Users should verify the state paths in s3 if they need to change this in case there are extra slashes in the keys (#20432)
config: path.module and path.root now return paths with forward slashes on all operating systems, including Windows. This avoids the need to write constructed paths differently for Windows vs. other operating systems, but any existing constructed paths containing backslashes for Windows must now be rewritten to use forward slashes, like "${path.module}/foo/bar". (#19708)
config: path.module and path.root are now relative to the current working directory, rather than absolute as before. This avoids including a host-specific absolute path prefix on constructed paths, but may show as a diff after upgrade in situations where a constructed path is included in a resource attribute value. (#19708)
tools/terraform-bundle: use the terraform-bundle of the same tag as the targeted terraform binary version. This avoids adding complexity to resolve protocol versions across different terraform versions. (#20030)

IMPROVEMENTS:

communicator/ssh: Add SSH certificate authentication (#18896)
communicator/ssh: Enable ssh keepalive messages for long running commands (#20437)
config: New set-theory functions sethaselement, setunion, setintersection, and setproduct for working with set values.
config: New type conversion functions tostring, tonumber, tobool, tolist, toset, and tomap. Explicit conversions are rarely required but occasionally useful; use these functions only when necessary.
plugins: Plugin RPC connection is now authenticated (#19629)
backend/azurerm: Support for authenticating using the Azure CLI (#19465)
backend/remote: Return detailed version (in)compatibility information (#19659)
backend/remote: Log early to indicate remote execution started (#19941)
backend/remote: Make sure the correct error is shown when having version incompatibilities (#20086)
backend/remote: Fix "token too long" errors when streaming remote operation logs (#20242)
backend/remote: Use the state.v2 service when using remote state only (#20379)
backend/remote: Use the can-queue-apply permission to detect if apply is allowed (#20460)

config: Detect and reject self-referencing local values (#19706)
config: Accept and ignore UTF-8 byte-order mark for configuration files (#19715)
config: More helpful error message for a situation that may arise on upgrade from Terraform 0.11 or earlier (#19727)
