 ### Media Variant Retention
 
+Similar to the new proxy feature, pict-rs 0.5 now sets a time limit on media variants, and discards
+them if they are not accessed within that time limit. Since variants can be regenerated on request,
+there's no harm in removing them to save on storage space.
+
+For configuration information, see the example
+[pict-rs.toml](https://git.asonix.dog/asonix/pict-rs/src/branch/main/pict-rs.toml).
+
 
 ### Configurable Temporary Directory
 
+pict-rs now supports using a non-default temporary directory. Previous versions of pict-rs have
+resorted to the operating system's defined temporary directory, and that is still the default
+behavior, but this can now be overridden from pict-rs' configuration.
+
+For configuration information, see the example
+[pict-rs.toml](https://git.asonix.dog/asonix/pict-rs/src/branch/main/pict-rs.toml).

 ### Serve From Object Storage
 
+pict-rs 0.5 now supports serving images directly from object storage. This is achieved by telling
+pict-rs the public URL at which your object storage is available in the object storage
+configuration. When this is set up, any existing image requested from pict-rs will be served with a
+redirect to the object storage URL. Since pict-rs is not intended to be exposed directly to the
+internet, any proxy between the internet and pict-rs must be configured not to follow redirects, or
+else that proxy will end up fetching the image from object-storage itself. In some cases, this might
+be reasonable (e.g. if Web Access is cheaper than S3API access for fetching files).
+
+For configuration information, see the example
+[pict-rs.toml](https://git.asonix.dog/asonix/pict-rs/src/branch/main/pict-rs.toml).
