What is CoolProp?

CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.

CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.

What is Meilisearch?

A week of walking back v1.52.0 while the sharding work ships on a parallel tag

Meilisearch spent the last week stabilising rather than shipping. v1.52.0 introduced SSE routes for tasks and batches plus a formatting speedup, and all three of the patch releases that followed reverted pieces of it — the SSE routes in v1.52.2 and the search speedup in v1.52.3. Meanwhile v1.53.0 landed on the same day as those patches, carrying sharding support for foreign filters and new index-size stats.

CoolProp 8.0 bought sub-microsecond property lookups — and shipped a desktop app alongside it.

◆ Current state

CoolProp released 8.0.0 in June 2026 after a long 7.x period, and paired it the same day with the first signed release of a Desktop GUI that had spent two months in unsigned alphas. The library release is dense: an SVD-compressed tabular backend giving sub-microsecond per-probe evaluation in the batched path, mass-basis vapor quality across HEOS and REFPROP, Chebyshev superancillaries for the SRK and Peng-Robinson cubics, a large fluid and mixture library expansion including the 2026 ASHRAE Standard 34 blends, and thread-safety work.

◆ Where it's heading

The project is moving on two fronts that reinforce each other: making evaluation fast enough to sit inside simulation inner loops, and putting a real application in front of engineers who previously had to write Python to use it. The new tabular backend being off by default in PropsSI says the maintainers are treating accuracy conservatively while the fast path proves out. The GUI's progression from unsigned alpha to notarized and SignPath-signed release in two months is the clearest sign it is meant as a product, not a demo.

◆ Prediction

Expect the SVDSBTL backend's default-off flag to be revisited once conformance data accumulates, and the GUI to continue on its own version line now that the signing and auto-update pipeline is live.

M6.3

A week of walking back v1.52.0 while the sharding work ships on a parallel tag

◆ Current state

Meilisearch spent the last week stabilising rather than shipping. v1.52.0 introduced SSE routes for tasks and batches plus a formatting speedup, and all three of the patch releases that followed reverted pieces of it — the SSE routes in v1.52.2 and the search speedup in v1.52.3. Meanwhile v1.53.0 landed on the same day as those patches, carrying sharding support for foreign filters and new index-size stats.

◆ Where it's heading

The distributed-search work is the throughline: foreign filters can now resolve documents across the network under sharding, and their retrieval ceiling moved from 100 to 1000 documents. That extends the federated-fetch-across-shards direction Meilisearch set out earlier rather than opening a new one. The push-based task streaming is the unsettled part — it shipped as experimental, came out two releases later, and has not returned.

◆ Prediction

Expect the SSE task and batch streams to reappear once the underlying issue is resolved, since the routes were explicitly framed as experimental rather than withdrawn. The sharding surface looks likely to keep widening on the same incremental cadence.
