Hi everyone,

With version 16.7.0, we have released the first part of the accessibility implementation for inputs that we have been working on for a long time. Based on the research we conducted during the implementation, we decided that many components needed changes in their structure and simplification, and these components were rewritten. Unfortunately, after extensive testing, there may be unexpected and unforeseen bugs that have emerged. We are grateful for your reports, and we are working to address them in the upcoming release!

Hi. I'm still having problems with the dropdown filter in versions bigger than 16.6.0.

I get the error 'TypeError: option.indexOf is not a function' in file 'node_modules/primeng/fesm2022/primeng-dropdown.mjs' every time i filter. This is happening with at least versions 16.9.1 and 17.

I had to downgrade to 16.6.0 even though i'm using angular 17.

The Multiselect filter is also not working properly.
