v0.4.0

0.4.0 (2026-11-10)

Upgrade notes

• config: sqlquack.toml now holds only your project's choices: [project] (sources, session and Python runtime), [allow] (name = true or false for each known difference) and [replace] (folder and verified). The evidence behind each translation is built in. Rewrite an old policy-style sqlquack.toml as [allow] lines; sqlquack explain --differences lists the names. --policy is now --config, and --builtin-policy is now --no-config. In Python, use ConvertOptions(config=…, no_config=…). --utc-session, --confirm-declared-offsets and --loud-divergences-only are removed.
• defaults: every known difference is allowed by default except hash, sequences, source_variant_json, variant_chain_type and project_udf. To refuse the value differences as --loud-divergences-only did, list them as false in [allow]; explain --differences marks which they are.
• strict: --strict refuses every known difference whatever [allow] says. It now treats a UTC session time zone and declared offsets as facts, so statements that rely only on them convert under --strict without the removed opt-in flags.
• sessions: with no configuration, session parameters that match a recorded session profile (for example WEEK_START) now convert. Parameters that match none are refused, with a line naming the parameter.
