Syntax of date conditions changed

I have some hundred locations where I use date conditions in order to show reservation links for seminars from the day of publication until the event and hide them from the first day of the event.
When I was using the last CC version in Joomla3 with CC version 4.5.2, I was using European data format in the condition like and it worked fine:
{show} date = "to 15.12.2022" <my_Text_here> {/show}. Meaning: An end date, no start date, German DD.MM.YYY style, fine.

Now, after migration to J4 and with CC version 4.5.2 I am forced to use the DD-MM-YYYY format ot the standard YYYY-MM-DD format. Also I am forced to set a start date before the "to". A "0" works as a start date.
- Is that new syntax meant to be like this? Or am I doing anything wrong? I will have to retype a few hundred date formats in more than 80 articles now.

Cheers,

Hi Peter,

thanks for the fast reply!

Actually I tried with the editor button to find the correct (new) syntax.
I know what the correct syntax is but I am surprised to see that the synatx is different from the previous versions and I wonder why.
Will it stay like this (then I will change all my syntax now) or will a fix or something come soon. Or is it is a matter of a setup somewhere.

Ralf

Ok, thanks for clarifying this.
