# 5.4.1

This release fixes regressions in 5.4.0.

## Installation on Termux

A change to the way Pillow detects libraries during installed prevented installation on Termux, which does not have `/sbin/ldconfig`. This is now fixed.

## PNG: Handle IDAT chunks after image end

Some PNG images have multiple IDAT chunks. In some cases, Pillow will stop reading image data before the IDAT chunks finish. A regression caused an `EOFError` exception when previously there was none. This is now fixed, and file reading continues in case there are subsequent text chunks.

## PNG: MIME type

The addition of limited APNG support to the PNG plugin also overwrote the MIME type for PNG files, causing “image/apng” to be returned as the MIME type of both APNG and PNG files. This has been fixed so the MIME type of PNG files is “image/png”.

## File closing

A regression caused an unsupported image file to report a `ValueError: seek of closed file` exception instead of an `OSError`. This has been fixed by ensuring that image plugins only close their internal `__fp` if they are not the same as `ImageFile`’s `fp`, allowing each to manage their own file pointers.
