 # Changelog for PSToml
 
+## v0.2.0 - 2023-05-23
+
++ Changed piping behaviour of `ConvertFrom-Toml` to build the final TOML string for each input rather than try and convert each string input as individual TOML entries
+  + This copies the behaviour of `ConvertFrom-Json` and makes `Get-Content $path | ConvertFrom-Toml` work as people would expect
+
 ## v0.1.0 - 2023-05-22
 
 + Initial version of the `PSToml` module
