Fedify: an ActivityPub server framework

We're excited to announce the release of Fedify 1.4.0! This release brings significant improvements to enhance compatibility and flexibility in #ActivityPub federation.

Key Highlights

Activity transformers

Introduced a new system to adjust outgoing activities for better compatibility with various ActivityPub implementations. This includes automatic ID assignment for activities and actor dehydration to satisfy implementation quirks (looking at you, Threads!).

WebFinger customization

Added the ability to customize WebFinger responses through the new mapAlias() API, giving you more control over how your actors are discovered.

New interaction collections

Added support for shares, likes, and emojiReactions properties to the Object class, making it easier to access and traverse these interaction collections.

CLI improvements

The fedify lookup command now supports two new options:

-t/--traverse: Traverse through collection objects
-S/--suppress-errors: Continue operation even when encountering errors during traversal

Other enhancements

Added Context.getNodeInfo() method for easier NodeInfo access
Improved error handling in collection traversal and JSON-LD processing
Added support for private network access control in WebFinger lookups
User-Agent headers now automatically include your instance URL, making it easier for other servers to identify your instance

Whether you're building a new federated application or maintaining an existing one, #Fedify 1.4.0 provides the tools you need for robust ActivityPub federation.
