What is cbcTools?
Two years quiet, then a release that makes its greedy design methods practical
cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.
What is SigNoz?
Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema
SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.

Two years quiet, then a release that makes its greedy design methods practical
◆ Current state
cbcTools generates and evaluates designs for choice-based conjoint experiments, gathering several strategies behind one method argument in cbc_design(): random, orthogonal via DoE.base, D-optimal, Bayesian D-efficient and greedy. That structure was set during 2023 across 0.4.0 and 0.5.0, which introduced the method argument, added strategies and documented in a table which options each one supports. The only release since, in August 2025, removes efficiency limitations from the greedy methods.
◆ Where it's heading
The package was explicitly built for extension — the 0.4.0 notes say the function is now better set up to add methods in future — and the pattern since has been adding or repairing one method at a time behind a stable interface. After a two-year gap the recent work is performance rather than coverage, which suggests the greedy methods were slow enough to be impractical at realistic design sizes. Restrictions have been added deliberately too, such as blocking the label argument for orthogonal designs because it would destroy orthogonality.
◆ Prediction
On the extension pattern the maintainer set up, the next release most likely adds another design method or continues tuning existing ones for speed; the entries do not indicate which.

Search without knowing the field — SigNoz keeps lowering the cost of not knowing your schema
◆ Current state
SigNoz is an OpenTelemetry-native observability platform, and its recent quarter runs on two threads: compatibility as a migration argument, and agent-readiness. The dashboard rebuild on the CNCF Perses specification was the clearest statement of the second. The newest release adds a search() function to the Logs Explorer that matches a literal, case-insensitive term across body, attribute and resource keys and values without the user knowing which field holds it, optionally narrowed to named field contexts.
◆ Where it's heading
Both threads keep advancing. PromQL conformance and an open dashboard schema lower the cost of moving to SigNoz from whatever is already installed; full-text search lowers the cost of not yet knowing your own telemetry schema, which is the same argument aimed at a new user's first hour rather than at a migration. Integration onboarding keeps expanding at a weekly clip, and the v1 alert history endpoints are running against an announced deadline.
◆ Prediction
Expect the schema-first treatment to reach alerts and saved views next, and the v1 alert history endpoints to disappear within a release or two; since search()'s own notes steer users toward field filters once the schema is known, field-context narrowing is the likely place it gets faster.
