The current 0.9.1 release is considered to be stable and is in production use at a few sites, including sites serving hundreds of thousands of requests per day. However there is a chance that API changes will be made leading up to the 1.0 release. We will attempt to keep these changes to a minimum and communicate them clearly in the release notes.
Using JiBX/WS for enterprise-level web services may require the addition of support for WS-Security and some form of attachments, as well as other types of extensions in the future. These extensions can all be done within the JiBX/WS framework, but the amount of work involved will probably require support through some form of commercial license. If you have a need for enterprise-level support or enhancements to JiBX/WS please contact Sosnoski Software Associates directly.
