So, I've spent about a week trying to resolve an issue where we had one sneaky user function annotated with [Function] that worked fine before the change, but when we updated to 19.0.25.211 everything stopped working normally which is documented but I would say this is really a change that users should be made more aware of.
We constantly evaluate the release history paying special attention to "breaking changes" but this is under the category of "improved" and no real indication that it could negatively affect someone's pre-existing reporting should they use [Function] in a way that is now .. changed. Especially when that change causes reporting errors, that are perceived as "broken".
We're already having a hard time justifying the very very fragile nature of using Telerik Reporting (re: vs designer, core vs netframework, the ticket was created in 2018 ...... !!!! Did you know your competitor's vs designer works properly in netcore/netframework??) but this was just so painful. Adding something more to the release notes would have prevented so much wasted time.
