         * Tweak linearization code to better handle files between 2 GB and
         4 GB in size. Fixes #1023.
 
-        * Fix serious bug: qpdf could discard a the character after an
-        escaped octal string. For content, this would only happen with QDF
-        or when normalizing content, but it could have happened in a
-        binary string. This bug was introduced between 10.6.3 and 11.0.0.
-        Fixes #1050.
+        * Fix data loss bug: qpdf could discard a the character after an

+        content, this would only happen with QDF or when normalizing
+        content. Outside of content, it could have happened in any binary

+11.6.3: October 15, 2023
+  - Bug fixes:
+
+    - Fix a bug in which qpdf could potentially discard a character in
+      a binary string if that character was preceded by an octal
+      escaped string with fewer than three digits. This bug was
+      introduced in the 11.0.0 release. The bug would not apply to
+      content streams with default settings.
+
+    - The linearization specification precludes linearized files that
+      require offets past the 4 GB mark. A bug in qpdf was preventing
+      it from working when offsets had to pass the 2 GB mark. This has
+      been corrected.
