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 SigNoz?
SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.
SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.

Dragonfly
5.0INFRA · APIS
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.
SigNoz
5.0INFRA · APIS
SigNoz sets November 11 to drop v1 alert rules and ships Telegram alerts and GCP logs.
◆ Current state
SigNoz ships a weekly changelog led by API deprecation notices. The October 22 edition sets November 11 for removing the v1 alert rule schema and endpoints, with stored rules rewritten to v2alpha1 on upgrade, and confirms the v1 alert-history endpoints are gone. It also moves saved views into the Explorer sidebar, rebuilds Notification Channels on the v2 API with richer Slack formatting, and adds Telegram alerts and GCP log collection.
◆ Where it's heading
SigNoz is retiring its v1 alerting API in stages, history first and rules next, while widening where alerts go (Jira, incident.io, now Telegram) and what it ingests. The August plugin for AI coding agents remains its main directional bet; recent weeks are platform cleanup around it.
◆ Prediction
Expect weekly reminders until November 11, then a release that removes v1 rules. Further alert channels and cloud-integration log sources are the likely feature follow-ups.
