+    - Moved the location of gcc attribute.
+
+      The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
+      was located after the function name. Builds with GCC 7 did not
+      indicate any problem, but GCC 8 issued errors. Moved the
+      attribute before the function name, as required.

+
+    - Reworked java test suite into individual JUnit tests.
+
+      Testing the whole suite of java unit tests in a single JUnit run
+      made it difficult to determine actual failures when tests would fail.
+      Running each file set of tests individually, allows individual failures
+      to be diagnosed easier. A side benefit is that tests for optional components
+      of the library can be disabled if not configured.

+    - The --enable-debug/production configure flags are listed as 'deprecated'
+      when they should really be listed as 'removed'.
+
+      In the autotools overhaul several years ago, we removed these flags and
+      implemented a new --enable-build-mode= flag. This was done because we
+      changed the semantics of the modes and didn't want users to silently
+      be exposed to them. The newer system is also more flexible and us to
+      add other modes (like 'clean').
+
+      The --enable-debug/production flags are now listed as removed.
