v0.1.3

Breaking

Adopting the upstream Broker and Trading documents, which are now OpenAPI 3.1.2 rather than 3.0.0,
changed two parts of the generated API surface.

• Broker EventsApi.subscribeToFundingStatusSSE now returns List<StatusFundingEvent>, and
  BrokerEventsSseClient.subscribeToFundingStatus emits StatusFundingEvent. The
  SubscribeToFundingStatusSSE200ResponseInner wrapper is removed; it only ever held a
  single-member union and now collapses to the member itself.
• Broker and Trading OrderLeg.getLegs() returns Object rather than List<Object>, and
  addLegsItem is gone. Upstream now declares the property as null-only, matching its existing
  documentation that legs are never nested beyond one level.

Fixed

• Preprocessing now normalizes the OpenAPI 3.1 constructs that the Java generator renders into
  uncompilable or under-typed code, so adopting a 3.1 document no longer silently degrades the
  generated clients:
  • A standalone type: 'null' schema became a ModelNull class the generator never emitted,
    breaking compilation. Null-only subschemas of anyOf / oneOf are left alone, since those
    are the idiomatic 3.1 spelling of "nullable" and already generate correctly.
  • A schema with items and no type is no longer read as an array, which had turned Broker
    FundingWalletsApi.listFundingDetails into a bare Object.
  • A oneOf of string enums is collapsed back into one enum, keeping Broker JournalStatusFrom
    and TransferStatusFrom as enums instead of AbstractOpenApiSchema wrappers.
  • Path-item parameters are inlined into each operation ahead of the operation's own parameters,
    which had otherwise duplicated Broker createTransferForAccount's account_id into a second
    accountId2 argument and reordered getOrderByClientOrderIdForAccount's arguments.

Changed

• GitHub Releases now use the curated CHANGELOG.md section for the tag (with a
  non-empty [Unreleased] fallback), then append GitHub’s compare link for the
  tag range. The release workflow fails before Maven Central if neither section
  has content, and the post-release bump PR promotes [Unreleased] to a dated
  version section when needed.
