-## Release notes
-
-### Version 0.5.2
-
-New features:
-
-- Allow EC signatures in DER format from signers and verify signature format during validation.
-- Fix bug in signing audio and video files in ISO Base Media File Format (BMFF).
-- Add the ability to verify PDF files (but not to sign them).
-- Increase speed of `sign_file` by 2x or more, when using file paths (uses native Rust file I/O).
-- Fixes for RIFF and GIF formats.
-
-### Version 0.5.0
-
-New features in this release:
-
-- Rewrites the API to be stream-based using a Builder / Reader model.
-- The functions now support throwing `c2pa.Error` values, caught with `try`/`except`.
-- Instead of `c2pa.read_file` you now call `c2pa_api.Reader.from_file` and `reader.json`.
-- Read thumbnails and other resources use `reader.resource_to_stream` or `reader.resource.to_file`.
-- Instead of `c2pa.sign_file` use `c2pa_api.Builder.from_json` and `builder.sign` or `builder.sign_file`.
-- Add thumbnails or other resources with `builder.add_resource` or `builder.add_resource_file`.
-- Add Ingredients with `builder.add_ingredient` or `builder.add_ingredient_file`.
-- You can archive a `Builder` using `builder.to_archive` and reconstruct it with `builder.from_archive`.
-- Signers can be constructed with `c2pa_api.create_signer`.
-- The signer now requires a signing function to keep private keys private.
-- Example signing functions are provided in c2pa_api.py
-
-### Version 0.4.0
-
-This release:
-
-- Changes the name of the import from `c2pa-python` to `c2pa`.
-- Supports pre-built platform wheels for macOS, Windows and [manylinux](https://github.com/pypa/manylinux).
-
-### Version 0.3.0
-
-This release includes some breaking changes to align with future APIs:
-
-- `C2paSignerInfo` moves the `alg` to the first parameter from the 3rd.
-- `c2pa.verify_from_file_json` is now `c2pa.read_file`.
-- `c2pa.ingredient_from_file_json` is now `c2pa.read_ingredient_file`.
-- `c2pa.add_manifest_to_file_json` is now `c2pa.sign_file`.
-- There are many more specific errors types now, and Error messages always start with the name of the error i.e (str(err.value).startswith("ManifestNotFound")).
-- The ingredient thumbnail identifier may be jumbf uri reference if a valid thumb already exists in the active manifest.
-- Extracted file paths for read_file now use a folder structure and different naming conventions.
