# pict-rs 0.4.3
## Overview
pict-rs 0.4.3 contains a single new feature and a few dependency upgrades. The primary motivation
for publishing this release is to produce new docker images containing the libwebp CVE fix released
within the last few days.
### Features
- [External Validation](#external-validation)
## Upgrade Notes
There's no significant changes from 0.4.2, so upgrading should be as simple as pulling a new version
of pict-rs.
## Descriptions
### External Validation
There is a new config option in the `[media]` section called `external_validation`. This setting
exists to allow custom validation of uploaded images in pict-rs, allowing 3rd party applications to
be developed for further filtering permitted uploads. When this value is set, pict-rs will upload
each uploaded file after initial ingest processing to the provided URL. The `Content-Type` header is
set to the file's media type, and the request's body is simply the uploaded file. The expected
response is a simple 2XX for files that pass validation, and any other status code for files that do
not (although I personally recommend a 4XX response).
This new value is optional. There is no default value and no first-party application is provided for
providing this extra validation.
