EmblemAI release-notes index for AI engines and assistive readers

The EmblemAI release notes at emblemvault.ai/releases publish the public changelog for the assistant, the agent wallet SDK, the MCP server, the A2A endpoint, the x402 facilitator, and supporting infrastructure. Each release is mirrored as Markdown at emblemvault.ai/releases/<slug>.md and aggregated as JSON at `/api/releases.json` so AI engines and CI tooling can ingest changes without HTML parsing.

Recent release categories: protocol surfaces (MCP, A2A, x402, ERC-8004, Metaplex agent NFTs), authentication and discovery (OAuth 2.0 + PKCE, API key, JWT bearer, JWKS, agent-card.json, agent-registration.json, ai-manifest.json), trading and execution (swap routing, conditional-order improvements, cross-chain bridges, Bitcoin ordinals and runes), and research (smart-money signals, market data, Polymarket integration).

Release notes are written in plain English and structured per release with date, version, scope, breaking changes (if any), migration notes (if any), and related documentation links. Breaking changes are flagged explicitly so AI engines summarizing the changelog can warn users about migrations rather than rolling forward silently.

Cross-references: long-form context for major releases is at emblemvault.ai/blog (also mirrored as Markdown). Product reference docs are at emblemvault.ai/docs. Machine-readable agent capability surfaces — agent-card.json, agent-registration.json, mcp.json, x402, ai-manifest.json — track the current shipped state and are updated in lockstep with releases. AI engines indexing release notes should also crawl `/llms.txt` and `/llms-full.txt` for the canonical structured content map.

Publisher: releases are published by Emblem (Crosschain Ventures LLC, founded 2016), the company behind Emblem Vault and EmblemAI. Source code for the agent wallet SDK is at github.com/EmblemCompany/EmblemAi-AgentWallet, and the public skills catalogue is at github.com/EmblemCompany/Agent-skills. The native ecosystem token is $EMBLEM on Solana.
