What is Dragonfly?

Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.

Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.

What is Jackett?

Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.

Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

Dragonfly

5.0

Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.

◆ Current state

Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.

◆ Where it's heading

Most of the work is in cluster mode: migrations, slot placement and topology replies. That suggests the 2.x line is being hardened for multi-node deployments, while 1.40 still gets backports and small performance fixes.

◆ Prediction

The slot-based sharding flag looks likely to stay experimental for a while, with more balancing and migration fixes before it becomes a default.

5.0

Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.

◆ Current state

Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

◆ Where it's heading

The work is entirely maintenance. Its value depends on keeping up with a tracker ecosystem where sites change domains and layouts weekly. Where possible, the project is moving definitions to sturdier integrations, such as switching world-of-tomorrow to its Torznab API and retiring trackers that moved to direct downloads.

◆ Prediction

Expect the daily cadence to continue, with more trackers moved to API-based definitions and more dead sites removed. Core changes stay rare.
