0.14.0 (Unreleased)
UPGRADE NOTES:
- configs: The
version
argument inside provider configuration blocks has been documented as deprecated since Terraform 0.12. As of 0.14 it will now also generate an explicit deprecation warning. To avoid the warning, use provider requirements declarations instead. (#26135) - The official MacOS builds of Terraform now require MacOS 10.12 Sierra or later. (#26357)
- TLS certificate verification for outbound HTTPS requests from Terraform CLI no longer treats the certificate's "common name" as a valid hostname when the certificate lacks any "subject alternative name" entries for the hostname. TLS server certificates must list their hostnames as a "DNS name" in the subject alternative names field. (#26357)
- Outbound HTTPS requests from Terraform CLI now enforce RFC 8446's client-side downgrade protection checks. This should not significantly affect normal operation, but may result in connection errors in environments where outgoing requests are forced through proxy servers and other "middleboxes", if they have behavior that resembles a downgrade attack. (#26357)
- Terraform's HTTP client code is now slightly stricter than before in HTTP header parsing, but in ways that should not affect typical server implementations: Terraform now trims only ASCII whitespace characters, and does not allow
Transfer-Encoding: identity
. (#26357) - The
terraform 0.13upgrade
subcommand and the associated upgrade mechanisms are no longer available. Complete the v0.13 upgrade process before upgrading to Terraform v0.14.
ENHANCEMENTS:
terraform plan
andterraform apply
: Added an experimental concise diff renderer. By default, Terraform plans now hide most unchanged fields, only displaying the most relevant changes and some identifying context. This experiment can be disabled by setting aTF_X_CONCISE_DIFF
environment variable to0
. (#26187)- cli: A new global command line option
-chdir=...
, placed before the selected subcommand, instructs Terraform to switch to a different working directory before executing the subcommand. This is similar to switching to a new directory withcd
before running Terraform, but it avoids changing the state of the calling shell. (#26087) - configs: Added
sensitive
argument for variable blocks, which supresses output where that variable is used (#26183) - configs: Added
alltrue
function, which returnstrue
if all elements in the given collection aretrue
. This is primarily intended to make it easier to write variable validation conditions which operate on collections. (#25656) - core:
terraform plan
no longer uses a separate refresh phase, all resources are updated on-demand during planning (#26270) - core:
ignore_changes
can now apply to map keys that are not listed in the configuration (#26421) terraform console
: Now has distinct rendering of lists, sets, and tuples, and correctly renders objects withnull
attribute values. (#26189)terraform login
: Added support for OAuth2 application scopes. (#26239)terraform fmt
: Will now do some slightly more opinionated normalization behaviors, using the documented idiomatic syntax. (#26390)terraform init
's provider installation step will now abort promptly if Terraform receives an interrupt signal. (#26405)- backend/consul: Split state into chunks when outgrowing the limit of the Consul KV store. This allows storing state larger than the Consul 512KB limit. (#25856)
- backend/consul: Add force-unlock support to the Consul backend (#25837)
- On Unix-based operating systems other than MacOS, the
SSL_CERT_DIR
environment variable can now be a colon-separated list of multiple certificate search paths. (#26357) - On MacOS, Terraform will now use the
Security.framework
API to access the system trust roots, for improved consistency with other MacOS software. (#26357)
BUG FIXES:
- backend/consul: Fix bug which prevented state locking when path has trailing
/
(#25842) - backend/pg: Always have the default workspace in the pg backend (#26420)
- backend/pg: Properly quote schema_name in the pg backend configuration (#26476)
- build: Fix crash with terraform binary on OpenBSD. (#26249
- command/clistate: return an error on a state unlock failure [#25729]
- command/format: Fix incorrect heredoc syntax in plan diff output (#25725)
- command/taint: If the configuration's
required_version
constraint is not met, thetaint
subcommand will now correctly exit early. (#26345) - command/taint, untaint: Fix issue when using
taint
(anduntaint
) with workspaces where statefile was not found. (#22467) - configs: Report an error when provider configuration attributes are incorrectly added to a
required_providers
object. (#26184) - core: Errors with data sources reading old data during refresh, failing to refresh, and not appearing to wait on resource dependencies are fixed by updates to the data source lifecycle and the merging of refresh and plan (#26270)
- core: Prevent evaluation of deposed instances, which in turn prevents errors when referencing create_before_destroy resources that have changes to their count or for_each values (#25631)
- lang/funcs: fix panic when
element()
is called with a negative offset (#26079) - lang/funcs:
lookup()
will now only treat map as unknown if it is wholly unknown (#26427) - states/remote: fix
state push -force
to work for all backends (#26190)
