v1.9.8-beta1 - v4.0.1 support, improved regex, and improved error code test

1.9.8-beta1 - 21/04/2026

Changed

• OpenAPI schema pattern fields are now compiled and evaluated using regexp2 (PCRE) at both spec load time and runtime request/response validation. RE2-compatible patterns are unaffected (RE2 is a strict subset of PCRE).

Added

• Added support for Open Banking UK v4.0.1 OpenAPI schema files

Fixed

• Fixed OB-400-DOP-101503 (v4.0) and OB-301-DOP-1015003 (v3.1) sending Content-Type: text/plain instead of application/json when posting the negative standing order consent payload, causing ASPSPs to respond with HTTP 415 instead of the expected HTTP 400.
• Fixed incorrect test case ID references in v1.9.6 release notes from OB-400-DOP-1015003 to OB-400-DOP-101503
