 ==========
 
 
+Version 1.6.0
+--------------
+
+Released 2024/6/4
+
+* Updated Python version to 3.12.
+* Revised the calculation of "today" to use the client's timezone instead of
+  the server's timezone.
+* Updated the Bootstrap, FontAwesome, and Tempus-Dominus versions in the test
+  site.
+
+
+Version 1.5.11
+--------------
+
+Released 2023/12/26
+
+Bug fix.
+
+* Refined to enable the selection of the 3351-001 Accumulated Profit or Loss
+  account.
+
+
+Version 1.5.10
+--------------
+
+Released 2023/11/28
+
+Bug fix.
+
+* Fixed the form validator to enable the selection of Accumulated Profit or
+  Loss accounts other than 3351-001.
+
+
+Version 1.5.9
+-------------
+
+Released 2023/11/28
+
+Bug fix.
+
+* Refined to enable the selection of Accumulated Profit or Loss accounts other
+  than 3351-001, facilitating the consolidation of existing balances.
+
+
+Version 1.5.8
+-------------
+
+Released 2023/10/24
+
+Bug fix.
+
+* Fixed an icon in the detail of the cash receipt journal entry.
+
+Released at Jaipur, India on vacation.
+
+
+Version 1.5.7
+-------------
+
+Released 2023/7/29
+
+Revised account title capitalization to capitalize account titles
+upon initialization of base accounts, rather than when displaying
+the accounts.  This prevents the system from incorrectly
+capitalizing titles of user-added accounts.
+
+For existing installation, run the ``accounting-titleize`` console
+command to capitalize the existing account titles that were already
+initialized.
+
+Other fixes:
+
+* Added missing documentation to the global variables, class
+  properties, and object properties.
+* Various minor fixes.
+
+
+Version 1.5.6
+-------------
+
+Released 2023/5/23
+
+Bug fixes.
+
+* Fixed the return URI of the creation forms to decode the next URI.
+* Fixed the unmatched offset list to use the encoded next URI.
+
+
+Version 1.5.5
+-------------
+
+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.
+
