This page contains the list of deprecations and important or breaking changes for Vault 1.4.6 compared to 1.4.5. Please read it carefully.

»AWS IAM Authentication Fixed

The security updates added in Vault 1.5.1, 1.4.4, 1.3.8, and 1.2.5 included additional header checking during AWS IAM authentication that caused issues for some users. A workaround was subsequently provided by setting allowed_sts_header_values.

The underlying issue has been corrected in 1.5.3, 1.4.6, 1.3.10 and 1.2.7, and setting allowed_sts_header_values is no longer needed. If that parameter has been set, it will not conflict with the fixed versions. It may be unset when convenient, or simply left as is.
