-    <notes>* The `maxminddb` extension is now buildable on Windows. Pull request
-  by Jan Ehrhardt. GitHub #115.</notes>
+    <notes>* When using the pure PHP reader, unsigned integers up to PHP_MAX_INT
+  will now be integers in PHP rather than strings. Previously integers
+  greater than 2^24 on 32-bit platforms and 2^56 on 64-bit platforms
+  would be strings due to the use of `gmp` or `bcmath` to decode them.
+  Reported by Alejandro Celaya. GitHub #119.</notes>
