     1  # Support Policy
     2  
     3  Version 1 of the Terraform Plugin SDK is considered **deprecated**, which means
     4  the following support policy is in place:
     5  
     6  - Critical bug fixes will be accepted and merged until July 31, 2021, at which
     7  point this version is considered End Of Life and no longer supported. New
     8  features and non-critical bug fixes will not be accepted.
     9  - We will not break the public interface exposed by the SDK in a minor or patch
    10  release unless a critical security issue demands it, and only then as a last
    11  resort.
    12  - We do not proactively test version 1 of the SDK against new releases of
    13  Terraform to ensure compatibility, but will address critical compatibility
    14  issues that are reported until July 31, 2021.
    15  - We do not backport bug fixes to prior minor releases. Only the latest minor
    16  release receives new patch versions.
