## Rust Version Compatbility
This crate is tested with the latest stable version of Rust. We do not
currrently test against other, older versions of the Rust compiler.
-## Upgrading from versions prior to 4.0
-
-If you are upgrading from version 3.0 or previous of this crate, you
-likely need to change your code to use [`ConvertedType`] rather than
-[`LogicalType`] to preserve existing behaviour in your code.
-
-Version 2.4.0 of the Parquet format introduced a `LogicalType` to replace the
existing `ConvertedType`.
-This crate used `parquet::basic::LogicalType` to map to the `ConvertedType`,
but this has been renamed to `parquet::basic::ConvertedType` from version 4.0
of this crate.
-
-The `ConvertedType` is deprecated in the format, but is still written
-to preserve backward compatibility.
-It is preferred that `LogicalType` is used, as it supports nanosecond
-precision timestamps without using the deprecated `Int96` Parquet type.
