I can confirm that after 4 hours, new version is shown on plugin page.
Same issue here:
– https://plugins.svn.ww.wp.xz.cn/tatrapay-payment-gateway/tags/1.0.5/README.txt
– Stable tag == 1.0.5
– and tags/1.0.5/ exists
But error is:
“The Stable Tag field is invalid, the specified SVN tag /tags/1.0.5/ does not exist. /trunk/ will be used instead.”
