+     both the textencodebase64 and textdecodebase64 functions to HCL2 templates.
+     Please note these functions return base64 encoded byte slices because of how

+* core: don't load plugins with metadata in name
+     To avoid confusion with multiple plugins that report the same effective version,
+     plugins installed need to have no metadata in their name.
+     When installed through packer commands, the metadata is scrubbed from the name of the
+     installed plugin binary, but manually it may still be possible, so we enforce
+     that scrubbing at load-time as well.
