* IO::Uncompress::Deflate
Beefed up the magic signature check. Means less false positives
when auto-detecting the compression type.
* IO::Uncompress::UnZip
Tighten up the zip64 extra field processing to cope with the case
wheere only some of the local header fields are superceeded.
* IO::Uncompress::AnyInflate
Remove raw-deflate (RFC 1951) from the default list of compressors
to check.
It can still be included if the new RawInflate parameter is
supplied.
This change was made because the only way to tell if content is
raw-deflate is to attempt to uncompress it - a few false positives
have popped up recently, which suggests that auto-detecting raw
deflate is far from perfect.
The equivalent change has been made to IO::Uncompress::AnyUncompress.
