I added a point to https://wiki.lazarus.freepascal.org/User_Changes_3.2.0#RTTI_changes I forgot to add a short personal rant :) The ambiguity of the /stored/ and /(no)default/ modifiers is a huge source of confusion and errors. Such a bad design :/ (Obviously FPC is not liable for it.) Having only the "stored" modifier would be so much simpler. (And you would be able to store all integer values in a property - currently you always have to choose one value that is not stored.)

Am 28.02.2021 um 23:11 schrieb Mattias Gaertner via fpc-pascal: Hi, In FPC 3.2.0 the default "Default" value of a single/double property has changed from $8000 (fpc 3.0.4) to 0. This breaks TWriter. The $8000 means the property has no default value. Now FPC 3.2.0 no longer writes a property if the value is 0.0, no matter what the stored function says. For example: property S: Single read FSingle write FSingle stored IsSStored; FPC 3.0.4 TWriter does write S if S=0.0 and IsSStored returns true. FPC 3.2.0 does not. It was indeed the fix for Mantis #31985 ( https://bugs.freepascal.org/view.php?id=31985 ) that changed this and the behavior of the RTTI is Delphi-compatible now. If you want the default value to be $8000 again you need to append "nodefault" to the property.
