What is Fiber?

Fiber v3 has sat in release candidate for months while v2 gets one-line patches

The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

What is Weaviate?

Weaviate 1.39 stacks Boost API GA, MMR diversity selection, 4-bit quantization preview, and an experimental Search REST API.

Weaviate 1.39 shipped four compounding retrieval improvements in one release: Boost API and MMR diversity selection moved to GA, 4-bit Rotational Quantization (RQ) was previewed as a memory-efficiency option, and an experimental Search REST API was introduced. The HFresh disk-based vector index — also now GA — gives users low-heap vector search with incremental background maintenance. A detailed post on 4-bit RQ benchmarks and SIMD performance trades off against TurboQuant, showing the engineering depth behind the feature.

Fiber v3 has sat in release candidate for months while v2 gets one-line patches

◆ Current state

The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

◆ Where it's heading

v3 is the answer to Fiber's longest-standing objection, that building on fasthttp cuts a project off from the net/http middleware ecosystem. Making both handler styles native reframes Fiber as compatible rather than separate. But rc.3 dates to late 2025 and nothing newer has landed in this feed, while v2 patches keep arriving through August — a long release candidate stretch that leaves users choosing between a stable branch in pure maintenance and a v3 that has not been declared final.

◆ Prediction

The next meaningful entry is either a v3.0.0 final or a further RC; until one lands, expect the v2 line to continue receiving single-PR backports and security patches.

6.3

Weaviate 1.39 stacks Boost API GA, MMR diversity selection, 4-bit quantization preview, and an experimental Search REST API.

◆ Current state

Weaviate 1.39 shipped four compounding retrieval improvements in one release: Boost API and MMR diversity selection moved to GA, 4-bit Rotational Quantization (RQ) was previewed as a memory-efficiency option, and an experimental Search REST API was introduced. The HFresh disk-based vector index — also now GA — gives users low-heap vector search with incremental background maintenance. A detailed post on 4-bit RQ benchmarks and SIMD performance trades off against TurboQuant, showing the engineering depth behind the feature.

◆ Where it's heading

Weaviate is building along two parallel axes: storage efficiency (scalar quantization, product quantization, 4-bit RQ, HFresh disk index) and retrieval sophistication (Boost API, MMR, Query Agent effort tiers, query profiling). The multi-part 'Building Foundry' series for creative archive search signals engagement beyond the standard enterprise knowledge base use case. The experimental Search REST API, if promoted to GA, would reduce the barrier for direct HTTP integrations without the Weaviate client library.

◆ Prediction

The experimental Search REST API will likely reach GA in the next one or two releases; the Query Agent's tiered effort modes (medium/high/ultrahigh) will probably exit preview once the REST API provides a stable access layer for external tooling.
