I recently updated to Zotero 7.0.10 (64 bit) running under Linux Mint.

Prior to installing version 7, when I created a PDF attachment, the attachment would likely have a weird or unwanted name. By right clicking, and selecting "Rename file from parent metadata", the file name (in the storage location) would be altered, and so do would the displayed name of the attachment. An example is visible in the attached screen shot for the item "The scoring of individual performance". The PDF name is seen to have been changed to "Thurstone - 1926 - The scoring of individual performance.pdf"

After installing Zotero 7, the behavior appears to have changed, as shown in the screen shot with the item "A necessary and sufficient condition for quantization error". When I right clicked the PDF, and selected "Rename file from parent metadata", the file name in the storage location was indeed changed ... but the display within Zotero continues simply to show "PDF".

Is the new behavior the intended behavior or a bug?
