+# 0.14.0 (Unreleased)
+
+NEW FEATURES:
+ - Add `ProtocolVersion` to `ReattachConfig` struct, enabling provider protocol v6 support in reattach mode, provided that Terraform and the provider plugin are both using go-plugin v1.4.1 or later. This change is backwards-compatible, as zero values for this field are interpreted as protocol v5. [GH-182]
