❗ Breaking Changes

• chore!: move joins to advanced.database.joins (#10359)

  If you previously set experimental: { joins: true }, update your config to:

  advanced: {
    database: {
      joins: true,
    },
  }
  

  Adapters that support native joins use them when enabled. If an adapter cannot return joined data for a query, Better Auth falls back to additional queries and combines the results. Drizzle and Prisma users should ensure their schema includes the required relations (npx auth@latest generate).

• feat(auth)!: scope accounts by issuer (#10403)

  This release is breaking. Account.accountId is renamed to Account.providerAccountId, and Account.issuer is required. Account-specific APIs select the local Account.id through accountId; token and provider-profile APIs can instead select the signed account cookie with useAccountCookie: true. Credential accounts use local:credential and the linked user's stable id as their provider identity. …

❗ Breaking Changes

• feat(captcha)!: support wildcard endpoint matching (#10004)

• feat(mcp)!: ship MCP as its own package built on the OAuth provider (#9992)

  The route helper is renamed requireMcpAuth (was withMcpAuth), and the remote client is createMcpResourceClient (was createMcpAuthClient). requireMcpAuth verifies the bearer token against the published JWKS and passes the verified JWT claims to your handler.

  To migrate, install @better-auth/mcp, add the jwt() plugin (now required for token signing), and move options that were nested under oidcConfig to flat options on mcp({ ... }). The database models change: oauthApplication becomes oauthClient, with new oauthRefreshToken and oauthClientAssertion tables. Regenerate or migrate your schema with npx auth migrate or npx auth generate.

• feat(oauth-provider)!: add OIDC back-channel logout (#9304) …

@better-auth/oauth-provider

❗ Breaking Changes

• Restricted customIdTokenClaims, extension ID-token claims, and per-issuance idTokenClaims from overriding protected OIDC/JWT protocol claims (#10140)

Migration: Remove any iss, sub, aud, exp, nonce, auth_time, acr, amr, or azp fields from customIdTokenClaims, extension ID-token claims, and per-issuance idTokenClaims. Use namespaced custom claims (e.g., "https://example.com/role") for application-specific data instead.

Features

• Added support for confidential DCR clients to complete authorization-code flows without PKCE when clientRegistrationRequirePKCE: false is set (#10146)
• Added support for the claims.userinfo authorization request parameter, allowing clients to request specific standard claims from the UserInfo endpoint (#10156)

Bug Fixes

• Fixed the UserInfo endpoint to accept bearer tokens in application/x-www-form-urlencoded POST request bodies (#10155)
• Fixed confidential clients that opted out of PKCE to successfully request offline_access when the authorization includes both openid scope and a nonce (#10153) …
