Changelog

v0.6.0 (2026-10-29)

What a source steps its window by: Window.before/4, region/2 (visualize's box/2: a window as the region it asks of a schema), range/2, and check/2 of the axes alone as well as of a request (dco-tek/macaw/macaw#185, #5).
Packing a table and reading it back do about half the work: types inferred only where not given, values checked in one pass, column names merged once, rows built a column step at a time, and time columns converted by the date's fields, a fifth of DateTime's own conversion (dco-tek/macaw/macaw#185, #4).
Breaking: a delivery keeps the rows its source gave (dco-tek/macaw/macaw#185). %Delivery{rows, names, types, served, schema, origin}: nothing is packed or rewritten when it is made; Delivery.rows/1 and Table.rows/1 of a delivery read the rows as they are (a row list uncopied, tuple rows unchanged); Delivery.table/2 and table!/2 pack them for a reader that wants columns; named_rows/1 names tuple rows and tensors by names:; empty?/1. The table field is gone: read Delivery.table!/1. Finishing and push keep the rows' form. Table.unnamed?/1 (#3).

The macaw logo in the docs and the README (macaw#175).
Tests check "makes no atom" on the input's own names, never the node's atom count, and the atom gate forbids the count in test/ (#1).

On Hex: depends on macaw_layers ~> 0.2.2 from Hex instead of its git tag, and the README installs from Hex (macaw#155).
The README opens with the early-release notice (macaw#174).

Dependencies named by their dco-tek/macaw group paths (macaw#152).
Package metadata for Hex: the public home, the changelog link, the files shipped, and docs with ex_doc (macaw_compose#155).
