What is bpbounds?

bpbounds found the same swapped-cell bug twice and clamped its bounds back into range

bpbounds computes nonparametric Balke-Pearl bounds on the average causal effect from instrumental variable data, in the bivariate and trivariate cases. After years of pure packaging maintenance, the two 2026 releases are analytical corrections. Bounds on intervention probabilities are now clamped to [0, 1] so derived causal risk ratio bounds cannot fall outside their feasible range, and a cell-ordering error in the trivariate three-category instrument path has been repaired.

What is Tinybird?

Every weekly release now pushes Forward further ahead of Classic before the September sunset.

Tinybird ships a descriptive weekly changelog, and the current window is dominated by ingestion. Remote files can now be imported through the v1 API to append or replace Data Source rows, v1 ingestion became the default for local files a week after arriving as experimental, and JSON integer handling was corrected. Reliability work runs alongside it: quarantined data persists across compatible deployments, and deployment backfills and validation got fixes.

bpbounds found the same swapped-cell bug twice and clamped its bounds back into range

◆ Current state

bpbounds computes nonparametric Balke-Pearl bounds on the average causal effect from instrumental variable data, in the bivariate and trivariate cases. After years of pure packaging maintenance, the two 2026 releases are analytical corrections. Bounds on intervention probabilities are now clamped to [0, 1] so derived causal risk ratio bounds cannot fall outside their feasible range, and a cell-ordering error in the trivariate three-category instrument path has been repaired.

◆ Where it's heading

The direction is toward agreement with the reference Stata implementation and away from silently wrong output. The clamping change is described as matching the same fix in the Stata package, which suggests the two implementations are being reconciled rather than developed independently. The cell-ordering defect is the more instructive one: it was fixed in the calculation function in 0.1.7 and then again in the constraint matrix in 0.1.8, meaning the same x=0,y=1 / x=1,y=0 swap had been written in two places.

◆ Prediction

Since the recent fixes came from an external contributor's report and both touched the trivariate three-category path, the untested corners of that path are where further corrections would surface — but the release notes give no roadmap beyond parity with the Stata package.

Every weekly release now pushes Forward further ahead of Classic before the September sunset.

◆ Current state

Tinybird ships a descriptive weekly changelog, and the current window is dominated by ingestion. Remote files can now be imported through the v1 API to append or replace Data Source rows, v1 ingestion became the default for local files a week after arriving as experimental, and JSON integer handling was corrected. Reliability work runs alongside it: quarantined data persists across compatible deployments, and deployment backfills and validation got fixes.

◆ Where it's heading

The Classic-to-Forward migration is the organizing fact, and the September 15 sunset for Free and Developer plans set the clock. Nearly every capability in this window lands on Forward or on the v1 surface, while Classic receives limits adjustments rather than features. Ingestion is where the investment is concentrated, moving from experimental to default in weeks.

◆ Prediction

Expect the v1 ingestion surface to keep absorbing sources — remote URLs now, likely more managed connectors next — and the remaining gaps in deployment and backfill reliability to close ahead of the sunset. The paid tiers still have no announced Classic end date.
