Changelog

Notable updates to the Playprint SDK and platform.

July 2026

@playprint/core 0.2.1 and @playprint/sdk 0.1.1 published to npm
Website now tracks @playprint/core from the npm registry (^0.2.0) instead of a vendored tarball
Fixed environment name mismatch: API keys created as live/test in the dashboard now correctly match SDK environments (dev, staging, prod)

Added rate limiting to the generate-bot endpoint (5 req/hr)
Admin login endpoint now returns 400 on malformed JSON instead of 500
Featured legends query bounded with LIMIT 200 to prevent unbounded table scans
Escaped SQL LIKE wildcards (%, _) in search inputs across legends, leads, and accounts
Added search input length caps to prevent oversized queries
COPPA cleanup cron migrated to daily schedule (0 3 * * * UTC) for Vercel Hobby plan compatibility

Published blog post: Drivatar-Style Ghost AI for Indie Games
Fixed API reference: corrected opponent_type values, decision.batch payload examples, profile response shape, and ingest response format
Added /legends/ and /gamepersonalitiesquiz to robots.txt and sitemap exclusions
Legends admin page updated from placeholder text to accurate status descriptions
CI workflow added: typecheck → test → build on pushes and PRs to master

New per-game pricing model with five tiers: Build (free), Launch ($49/mo), Grow ($149/mo), Comply ($499/mo), Enterprise (custom)
Added COMPLY tier with COPPA compliance tools, parental consent flows, data minimization, and audit documentation
BUILD tier is free forever during development with no MAU limits

Ghost AI expanded from 5 to 8 bias weights — now includes reach (from expansive trait), expressiveness, and provocation (from CommsProfile). Ghosts can now drive in-game emotes, chat, and messaging behaviour.
createGhost() now accepts an optional CommsProfile second argument for communication-aware ghosts
Ghost modifier composition pipeline (composeModifiers, conditionalModifier) for dynamic AI behaviour tuning
State-action resolution with hierarchical fallback keys (resolveStateAction, buildFallbackKeys)
Communication style classification — profiles players as Silent, Trash Talker, Expressive, or Respectful (deriveCommunicationBiases, classifyCommunicationStyle)
Decision classification with category maps and keyword inference fallback (classifyDecision)
Game module registry for per-game SDK configuration (registerGameModule, getGameModule, getAllGameModules)
Ghost profile generation from game modules (buildGhostProfileFromModule)
Match tracker creation from game modules with risk map support (createTracker)
Typed extensions — PlayprintData<T> generic for type-safe game-specific extension fields
Version comparison utility (compareVersions)
6-dimensional trait profile (Aggressive, Bold, Deceptive, Chaotic, Urgent, Expansive)
5-layer generative archetype system
Exponential Moving Average profile computation
Zero runtime dependencies

Redesigned pricing page with per-game model and cost estimator
Added compliance positioning section for children's game studios
Added ROI Calculator for studios to estimate retention impact
Updated Cross-Game Identity documentation to reflect infrastructure-complete status
Added Core Concepts documentation page
Added Compliance documentation with data flow diagrams
Published Privacy Policy and Terms of Service
Added waitlist registration for early access
