Version history

GAOS evolves additively across the v0.x line. Products can adopt new mechanism families independently, while deprecated compatibility names remain available until the v1.0 boundary.

Current source: v0.16.0

The latest batch expands GAOS from a grid-focused engine into a composable tabletop mechanism suite: heterogeneous boards, hidden information, zones, card-play composition, portals, high-frequency lockstep, and multi-agent episodes.

Tabletop mechanism suite

v0.16.0 — portals and multi-agent play

Prepared July 23, 2026.

• Atomic portal planning and commit across square, hex, and graph boards and ordered, bag, or slotted zones.
• Bounded multi-hop traversal, cycles, groups, footprints, transformations, destination capacity, and deterministic contention.
• Frame skipping for decision-point agents with transcript v1.2.
• Seat-redacted MultiAgentEnvironment episodes with canonical simultaneous batches and per-seat rewards.
• Authoritative hidden-information deployment guidance, including per-match server resolvers and optimistic P2P dispute verification.

v0.15.0 — zones and card composition

Prepared July 23, 2026.

• Ordered, bag, and sparse slotted zones with atomic transfers.
• Seeded shuffle, draw, round-robin dealing, and batch dealing.
• Keyword layers, response priority, declarative targets, durations, phase hooks, and deck/squad validation.
• Priority resource claims for contested draft picks and capacity.

v0.14.0 — information partitions

Prepared July 23, 2026.

• Deterministic viewFor(state, seat) observations.
• Independent identity and order visibility for zones.
• Fog-of-war, entity shells, leak assertions, revelations, teams, spectators, and ranked multi-seat outcomes.
• Turn order, participation descriptors, pattern matching, sparse tick transcripts, rollback resimulation, and state digests.

v0.13.0 — neutral core and layouts

Prepared July 23, 2026.

• Genre-neutral reducer, action, solver, and replay names.
• Deprecated v0.12 aliases retained with equivalent behavior.
• LocationRef addressing across multiple containers.
• Square, axial-hex, and directed-graph layouts with generic pathfinding, line-of-sight, fields, and keyed movement.

Compatibility policy

• v0.13 through v0.16 are additive.
• Existing single-board and perfect-information reducers continue to work.
• The old Grid* core names remain deprecated aliases through v0.x.
• v1.0 removes those aliases and is the next intentional breaking boundary.
