 ==========
 
 
+Version 1.5.11

+Version 1.5.9
+-------------
+
+Released 2023/11/28
+
+Bug fix.

+  than 3351-001, facilitating the consolidation of existing balances.
+
+
+Version 1.5.8
+-------------
+
+Released 2023/10/24
+
+Bug fix.

+command to capitalize the existing account titles that were already
+initialized.

+  properties, and object properties.
+* Various minor fixes.

+Released 2023/5/23
+
+Security fixes.
+
+* Revised the next URI utilities to encode and decode the next URI
+  preventing tampering with the next URI.
+* Added the integrity value of the CDN stylesheet links.
+* Various fixes.
+
+
+Version 1.5.4
+-------------
+
+Released 2023/5/18
+
+Security fixes.
+
+* Added safeguard to the next URI utilities, to prevent Cross-Site
+  Scripting (XSS) attacks.
+* Applied the safe next URI utilities to the test site.
+* Added the ``SameSite`` and ``Secure`` flags to the session cookie
+  of the test site.
+
+
+Version 1.5.3
+-------------
+
+Released 2023/4/30
+
+* Fixed the error of the net balance in the unmatched offset list.
+* Revised the original line item editor not to override the existing
+  amount when the existing amount is less or equal to the net
+  balance.
+
+
