Alopex DB v0.8 Series¶

v0.8.10 — Types, nested values, and full-text search¶

• Added exact DECIMAL/NUMERIC with up to 38 digits, stored as a signed 128-bit coefficient and a scale, and carried through Arrow/Parquet Decimal128, Python decimal.Decimal, and decimal CLI output.
• Added native DATE, TIME, and INTERVAL values with month/day/microsecond components kept separate, plus MAKE_*, AGE, DATE_ADD, DATE_SUB, and timestamp GENERATE_SERIES. The existing TIMESTAMP representation is unchanged.
• Added a native JSON type (JSONB is a dialect alias) with ->, ->>, #>, #>>, JSONB_SET/JSONB_INSERT, the JSONB_BUILD_* constructors, and JSONB_AGG/JSONB_OBJECT_AGG. The earlier SQLite-compatible JSON-on-TEXT functions remain compatible.
• Added nested ARRAY/LIST, MAP, and STRUCT values with subscripts, slices, UNNEST … WITH ORDINALITY, the ARRAY_* scalar catalog, and ARRAY_AGG.
• Added deterministic local full-text search: TO_TSVECTOR, TO_TSQUERY, PLAINTO_TSQUERY, WEBSEARCH_TO_TSQUERY, TS_RANK, TS_HEADLINE, and FTS_SEARCH, with transactional USING FTS indexes that do not change result semantics.
• The v0.8 type capability gate records every v0.8.10 family as complete. The distributed execution catalog keeps non-portable JSON, temporal, nested, and full-text functions local-only.
• Updated the Nim parser wire contract to 0.19.0.

v0.8.9 — Portable SQL and KV functions¶

• Added portable UTC timestamp, math, string, regex, statistics, regression, value, bitwise, and boolean aggregate functions.
• Added bounded byte-glob and byte-regex KV key search across embedded, async, HTTP, and CLI surfaces.
• Updated the Nim parser wire contract to 0.15.0.

v0.8.8 — Portable relational grammar and durability fixes¶

• Added portable relational grammar including LATERAL, grouping sets, aggregate filters, DISTINCT ON, standard pagination, and TRY_CAST.
• Added the Python server client and verified mode parity from published packages.
• Added single-file convergence and rejected concurrent opens of one data directory.

v0.8.7 — CTE and window correctness¶

• Added recursive CTEs, CTE column-name lists, LAG/LEAD, explicit window frames, and grouped-window composition.
• Mapped bounded execution exhaustion to stable public error code ALOPEX-E003.

v0.8.6 — Single-node SQL correctness¶

• Added projection-alias resolution in ORDER BY and HAVING, with explicit scope errors where aliases are not visible.
• Added REAL, searched/simple CASE, and UNION/INTERSECT/EXCEPT.
• Added non-recursive CTEs and basic aggregate/ranking window functions.
• Rebuilt every native Nim parser asset from the v0.8.6 tag while retaining parser contract 0.4.0.

v0.8.5 — Public surface and release hardening¶

• Restored release parity for Python vector, HNSW, SQL-stream, and scan APIs.
• Hardened parser asset assembly, wheel linkage, security gates, and post-publication verification.

v0.8.4 — Parser contract 0.4.0¶

• Added CREATE CONTINUOUS AGGREGATE to the parser contract.
• Shipped target-qualified parser assets and checksum manifests for supported Linux, macOS, and Windows targets.

v0.8.3 — SQL correctness and name resolution¶

• Numeric JOIN keys now match by value across integer and floating-point types.
• USING and NATURAL JOIN keys remain correctly merged across chained joins.
• Duplicate aliases, quoted/unquoted identifier rules, derived-table scope, and parser diagnostic spans are handled consistently.
• Wide-schema and deeply nested name resolution were optimized.

v0.8.2 — SQL correctness¶

• Fixed TIMESTAMP input, numeric promotion, integer SUM, CAST, IN, BETWEEN, subquery scope, and RIGHT/FULL JOIN merged keys.
• Added INSERT ... SELECT, qualified wildcards, and statement-stable NOW().
• SUM(INTEGER) now returns BIGINT; this is a documented result-type change.

v0.8.1 — Parser contracts¶

• Added PromQL and SQL-TS contracts to Nim parser ABI 0.2.0.
• Hardened Windows release coverage for Python, streaming, and server surfaces.

v0.8.0 — Cluster-aware streaming¶

• Added cluster metadata, lifecycle, routing diagnostics, and authenticated distributed-read contracts.
• Added multi-statement and streaming SQL over HTTP, gRPC, and CLI.
• Added bounded CSV/Parquet DataFrame streaming and sync/async Python APIs.
• Single-node remains the default; remote execution and distributed transactions are not part of the v0.8 supported scope.

Skulk v0.4.0¶

• QueryEngine executes PromQL instant/range queries, SQL-TS, and pre-built logical plans without requiring an HTTP server; results stream as Arrow RecordBatch values.
• PromQL covers selectors, ranges, offsets, arithmetic, core range functions, classic histogram quantiles, and grouped aggregates. SQL-TS covers projection, filtering, ordering, aggregates, TIME_BUCKET, RATE, DELTA, DERIVATIVE, FIRST, and LAST.
• StorageReader combines pending and durable latest-write-wins data with time, tag, and field pruning. v0.3 WAL, manifest, and Parquet data remains readable.
• The default build enables PromQL and SQL-TS through the Nim parser. A --no-default-features pure-Rust embedded profile remains available.
• HTTP query endpoints are still planned for v0.6; the text frontends implement documented subsets and reject unsupported semantics explicitly.

Chirps v0.6.3¶

• Restores conformance with the memory and mTLS specifications.
• Builds on v0.6.2's per-connection memory bounds in the production QUIC path.

• Retains the v0.6.1 OpenRaft-compatible storage/node APIs, hardened SWIM, resumable file transfer, and observability surface.

• MessageProfile::Durable still awaits the planned Iggy backend.
