[libextractor] libextractor 1.7 released

[Christian Grothoff]

Dear all,

I'm happy to announce the release of GNU libextractor 1.7.


About GNU libextractor
======================

GNU Libextractor is a simple library used to extract meta data from
files. The goal is to provide developers of file-sharing networks,
browsers or WWW-indexing bots with a universal library to obtain simple
keywords and meta data to match against queries and to show to users
instead of only relying on filenames. GNU libextractor contains the
shell command "extract" that, similar to the well-known file command,
can extract meta data from a file an print the results to stdout.

Currently, GNU libextractor supports the following file formats: HTML,
MAN, PS, DVI, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw),
FLAC, MP3 (ID3v1 and ID3v2), OGG, WAV, S3M (Scream Tracker 3), XM
(eXtended Module), IT (Impulse Tracker), NSF(E) (NES music), SID (C64
music), EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), LZH, LHA, RAR,
ZIP, CAB, 7-ZIP, AR, MTREE, PAX, CPIO, ISO9660, SHAR, RAW, XAR FLV,
REAL, RIFF (AVI), MPEG, QT and ASF. Also, various additional MIME types
are detected.

GNU libextractor uses helper-libraries (plugins) to perform the actual
extraction.  As a result, GNU libextractor can be extended simply by
installing additional plugins.  Writing robust parsers can be difficult.
GNU libextractor protects the main applications from haning or crashing
plugins by executing all plugins out-of-process.

GNU libextractor is written in C.  However, a binding for Java exists.


Noteworthy improvements in 1.7
==============================

* Tolerate failure to find AppArmor resource failures by continuing
  instead of aborting (on systems where AppArmor support was compiled
  in).
* Fix FTBFS issue with FFmpeg 4.0
* Fix infinite output issue in mpeg plugin for certain inputs
* Fix stack smashing issue in zip processing logic
* Fix misc. NULL pointer exceptions and integer overflow in DVI plugin
* Fix minor memory leak
* Updated Spanish translation

Upgrading is highly recommended.
