ODataFeed has no 10,000-row page limit, reducing HTTP round-trips for large tables from 50+ requests to 1-5. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Accept a filters parameter as either a raw OData string or a dict mapping dimension keys to value lists. periods param still works and is combined with filters using AND. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Accept column names as human-readable titles or CBS keys. Maps titles back to keys for the $select OData parameter. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
When typed=False, fetch UntypedDataSet to preserve CBS statistical symbols (. = not applicable, x = suppressed, - = nil) instead of replacing them with null. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add documentation for filters, columns, typed parameters. Add half-yearly period format. Remove references to deleted dutch_name and display_name fields. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Phase 2 enhancements to cbspy, adding power-user features to
get_data()and improving performance for large tables.New features
filtersparameter) — Filter any dimension using a dict of key→value lists (e.g.filters={"RegioS": ["GM0363", "GM0599"]}) or a raw OData$filterstring. Combines with the existingperiodsparameter via AND logic.columnsparameter) — Restrict returned columns using human-readable names (e.g."Total population") or CBS keys (e.g."TotalPopulation_1"). Maps titles back to OData$selectkeys automatically, reducing bandwidth for wide tables.typed=False) — Fetch fromUntypedDataSetinstead ofTypedDataSetto preserve CBS statistical symbols (.= not applicable,x= suppressed,-= nil) that are normally replaced with null.2023HJ01→"2023 H1"and2023HJ02→"2023 H2".Performance
