-==== Incompatibilities with upcoming JDBC 4.5 Specification
-
-// TODO Revise/rename with state for Jaybird 6.0.5 once https://github.com/FirebirdSQL/jaybird/issues/907 is complete
-
-This section applies to Jaybird 6.0.4 and earlier.
-
-Java 26 (expected in March 2026) will introduce https://jcp.org/aboutJava/communityprocess/maintenance/jsr221/index5.html[JDBC 4.5^] (link to draft).
-Jaybird is not yet compatible with some of the specified changes.
-
-Specifically affected are:
-
-* Introduction of `java.sql.JDBCType.DECFLOAT` and `java.sql.Types.DECFLOAT` (value `2015`).
-+
-At this time, Jaybird still uses its own constants in `JaybirdType.DECFLOAT` and `JaybirdTypeCodes.DECFLOAT` with value `-6001`.
-This value will be changed to match the JDBC specified value, and the constants deprecated, in a future maintenance release of Jaybird.
-+
-Addressed in Jaybird 6.0.5.
-* Introduction of new methods on `java.sql.Connection` -- `enquoteIdentifier`, `enquoteLiteral`, `enquoteNCharLiteral`, and `isSimpleIdentifier`
-+
-The default implementation provided is not sufficient for Firebird, especially not when connecting to a dialect 1 database.
-For the time being, we recommend using the equivalent JDBC 4.3 methods (with the same name) on a `java.sql.Statement` instance of the connection.
-+
-Addressed in Jaybird 6.0.5.
-* The JDBC escape to selectively disable escape processing ([.nowrap]`++{\ ... \}++`) is not yet implemented.
+==== Compatibility with the JDBC 4.5 Specification
 
-We plan to address these issues in Jaybird 5 and Jaybird 6 maintenance releases _after_ the release of Java 26 (tracked by https://github.com/FirebirdSQL/jaybird/issues/907[#907]).
+Java 26 (March 2026) introduced https://jcp.org/aboutJava/communityprocess/maintenance/jsr221/index5.html[JDBC 4.5^] (link to draft).
+Since Jaybird 6.0.5 (and Jaybird 5.0.12), Jaybird is compatible with the specified changes.
