What is Dragonfly?

Dragonfly spends its releases on correctness in the parts of Redis compatibility nobody tests.

The visible window is almost entirely correctness and internals work on the 1.39/1.40 lines. The newest release consolidates two tiering knobs into a single tiered_max_pending_bytes and exports it to metrics. Behind it sit a memory-accounting backport, a cluster fix that journals FLUSHSLOTS from inside the flush transaction, and a HyperLogLog resync with valkey upstream that pulled in a CVE fix and exposed three Dragonfly-local bugs.

What is medicalcoder?

A comorbidity-coding package relicenses to BSD and grows past the American coding systems

medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.

Dragonfly spends its releases on correctness in the parts of Redis compatibility nobody tests.

◆ Current state

The visible window is almost entirely correctness and internals work on the 1.39/1.40 lines. The newest release consolidates two tiering knobs into a single tiered_max_pending_bytes and exports it to metrics. Behind it sit a memory-accounting backport, a cluster fix that journals FLUSHSLOTS from inside the flush transaction, and a HyperLogLog resync with valkey upstream that pulled in a CVE fix and exposed three Dragonfly-local bugs.

◆ Where it's heading

Two threads run through this window. One is upstream parity — the hyperloglog sync explicitly re-forks from valkey and keeps upstream formatting so future syncs stay cheap, which is a maintenance-cost decision as much as a correctness one. The other is the RESP IO loop v2 migration, visible in a pub/sub ordering fix gated on the v1 loop and in tests being skipped on the v1 leg of the regression matrix. Dragonfly is hardening a drop-in Redis replacement in the places where drop-in claims usually break: cluster operations, pub/sub ordering under pipelining, and memory accounting.

◆ Prediction

Expect continued RESP IO loop v2 work and more upstream syncs on forked Redis internals. The tiering flag consolidation plus its metrics export suggests tiered storage tuning is the next area to get operator-facing surface.

A comorbidity-coding package relicenses to BSD and grows past the American coding systems

◆ Current state

medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.

◆ Where it's heading

Two things are happening at once. The coding surface is broadening — ICD-10-AM, ICD-10-SE, Swedish register-based and MIMIC-IV-consistent Charlson methods — which points at users outside the US claims-data world. Separately, the package is hardening: validation on encounter ordering, deterministic result ordering, NA rather than NaN for zero counts, and corrected AHRQ and Quan mappings for fiscal years 2023 to 2026. The mapping argument is the first real fork in how the computation runs rather than what it covers.

◆ Prediction

Regex mapping is currently unavailable for charlson_beyrer2021 and the release notes flag it as a gap, so closing that is the most clearly signposted next step.
