What is PINstimation?
A market-microstructure toolkit that keeps adding estimators as the papers land.
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.
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.

◆ Current state
PINstimation estimates probability-of-informed-trading models — PIN, multilayer PIN, adjusted PIN and VPIN — from trade and quote data, and handles the trade classification and aggregation that feeds them. The current 0.2.0 adds ivpin(), a maximum-likelihood variant of VPIN from Ke and Lin (2017). The package's early history is compressed into a single hour of backfilled tags in October 2022, so version order there does not track release order.
◆ Where it's heading
Each release tracks the literature: a Bayesian PIN estimator from Griffin et al., an improved VPIN from Ke and Lin, initial-parameter generation realigned to Ersan and Ghachem. The other steady thread is data handling — matrix inputs so the estimators compose with rolling windows, user-specified aggregation frequencies, and now quote leads as well as lags. The three-year gap between 0.1.2 and 0.2.0 makes this a slow, publication-paced package rather than an actively developed one.
◆ Prediction
On this pattern the next release adds whatever estimator the authors publish next, since two of the three feature releases here implement a specific paper. Nothing in the entries points to a change in the package's structure.

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.
