The "newer handler" basically seems to be in place since 2001[1] (i.e. long before PHP 5.0.0), so the documentation doesn't have to mention it in the changelog.

Current documentation is valid for old PHPs which are no longer supported. ------------------------------------------------------------------------ [2013-08-05 09:21:24] marc at ermshaus dot org Description: ------------ This is more or less a duplicate of this bug report: - https://bugs.php.net/bug.php?id=52229 I am opening a new one because I think my comment there went by unnoticed. http://www.php.net/manual/en/ini.core.php#ini.post-max-size states: “If memory limit is enabled by your configure script, memory_limit also affects file uploading. Generally speaking, memory_limit should be larger than post_max_size.” To me, the phrasing is misleading as it implies that file uploads (<input type="file">, multipart/form-data, $_FILES array) have to fit into memory_limit. That is probably not the case. It is my understanding that the second sentence from the quote only holds true for large application/x-www-form-urlencoded POST requests (without file uploads) while the first sentence is more or less incorrect/superfluous. For example, uploading two 4M files with settings memory_limit 2M, post_max_size 10M, upload_max_filesize 5M should work. 4M < upload_max_filesize and 4M+4M < post_max_size. memory_limit should not affect this at all.
