Changelog missing after plugin update

Hi. We’ve updated our plugin a few days ago and included some changelog entries as usual. However, the changes are not displayed on the plugin changelog page:
https://ww.wp.xz.cn/plugins/ecwid-shopping-cart/changelog/

The latest changelog entries are of 3.4.4 version, while the current stable version is 3.4.5.

Here are the links to the changelog section of the readme file from trunk and latest version:
https://plugins.trac.ww.wp.xz.cn/browser/ecwid-shopping-cart/trunk/readme.txt#L109
https://plugins.trac.ww.wp.xz.cn/browser/ecwid-shopping-cart/tags/3.4.5/readme.txt#L109

Is it something that we are missing here, any ideas how to fix that?

Thank you.
