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
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.
More flexible document/context loader
Document loader and context loader are now configurable through factory functions, giving you more control over how your application handles JSON-LD documents.
CLI improvements
The fedify lookup command now supports two new options:
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
