Unclear It is not clear whether more paths, such as process files, are now refused or only the message wording changed.
What
The Read tool is the tool Claude uses to read files. It refuses some special files, such as devices. Its refusal now says that the path names a device or process file that the tool does not read. Before, it said the device file would block or produce endless output.
Why
If you see Claude unable to read one of these paths, the message is worded differently and now also names process files.
