 ## Message type by name
 If you prefer to assert by message name instead of type code, use hasMsgTypeName(..). The lookup uses the session/application data dictionaries for the message’s version.

 ## FIXT.1.1 and ApplVerID
 For FIXT.1.1 sessions (BeginString FIXT.1.1), the effective application BeginString is derived from ApplVerID using QuickFIX/J’s MessageUtils.toBeginString mapping. This library handles that internally, so field type and message name lookups behave as if you were on FIX.5.0, FIX.5.0SP1, or FIX.5.0SP2.

 You can register custom data dictionaries when asserting messages, for example if you have user-defined fields or variants.

 DataDictionary dd = new DataDictionary("path/to/FIX40.xml");

 - The registration applies process-wide during the test run; prefer to register in a setup method and restore state between tests if needed.

 ## Compatibility
-- Java: 8, 11, 17
+- Java: 11, 17, 21
 - QuickFIX/J: tested with 2.3.2; should work with other 2.x
 - AssertJ: 3.x (the project’s pom uses a version range; pin a modern 3.x if you manage via BOM)
 
 If you work with older dictionaries or custom ones, ensure they are compatible with your QuickFIX/J version.
 
 
 ## Build and test locally
