JHOVE 1.11

GENERAL

1. I've added lots of logging code. Calls at the FINE level and lower
   don't show up no matter what I do, so I've put them at the INFO level.
   The level is set in JhoveBase.java.
2. All .bat and _bat.tmpl files now have CR-LF line endings. That is, they
   do in the gzip and zip archives you download. I'm not sure how
   SourceForge will treat files that you download individually,
   but hopefully it will have the sense to keep CR-LF when downloading
   to a Windows system.
3. All .bat files now assume JHOVE_HOME is the directory from which they're
   run. They no longer try to set JAVA_HOME (which was still stuck in
   Java 1.4 and probably wasn't working for many people), instead assuming
   that the JAVA command is available on the command line.
4. All javac commands in build.xml files now specify source=1.5 for
   compatibility with more recent compilers.
5. gdumpwin.bat is deleted. It's redundant with gdump.bat and has bugs
   of its own.

PDF MODULE

1. Fix to PDF module, submitted by willp-bl, may reduce tendency
   to run out of heap space on some files.

JHOVE 1.10

GENERAL

1. The amount of logging code has been increased, mostly at the
   DEBUG level.
2. Further work on generics in Java code.
3. JhoveView now checks for Java 1.5. Was previously allowing 1.4 even
   though it wouldn't work.

HTML MODULE

1. XHTML files are processed by the HTML module, which invokes the XML
   modules. In this case, the XML module doesn't have the parameters
   specified in the JHOVE configuration file and so won't use local
   copies of schemas. Starting with this version, the parameters of
   the HTML module are passed to the XML module when invoking it.
   However, this doesn't work properly (in either module) for a DTD
   that invokes additional DTDs by relative URLs. Such DTDs should
   be edited to use only absolute URLs.

PDF MODULE

1. Failure to get a page object number wasn't being handled cleanly,
   resulting in a report of an invalid document without an error message
   to explain it (SourceForge bug 49). This has been fixed.
2. The PDF module unnecessarily uses huge amounts of memory to build
   complex structure trees, when it doesn't need to keep the whole
   tree in memory to validate it. In the new version, it uses memory
   more economically. This should result in the successful processing
   of some PDF files that ran out of memory or took hours to process before.
3. If an annotation isn't a dictionary object, report that explicitly.
   This happens with some otherwise good files; I can't find any warrant
   for it in the PDF spec.
4. Some efficiency improvements to PDF parser. Increased buffer size from 4K
   to 64K. Made Parser.collapseObjectVector more efficient. Parser now
   returns pseudo-objects for array and dictionary end instead of throwing
   an exception.
5. Minor cleanup of error reporting.
6. If an object uses a compression scheme which JHOVE can't deal with, JHOVE
   will try to give a specific error message.

JHOVE 1.9

GENERAL

1. Jhove.java and JhoveView.java now get their version information from
   JhoveBase.java. Before it was redundantly kept in three places, and
   sometimes they didn't all get updated for a new release. Like in 1.8.
2. ConfigWriter was in the package edu.harvard.hul.ois.jhove.viewer, which
   caused a NoClassDefFoundError if non-GUI configurations didn't include
   JhoveViewer.jar in the classpath. It's been moved to
   edu.harvard.hul.ois.jhove.
3. Added script packagejhove.sh and made md5.pl part of the CVS repository
   to make packaging for delivery easier.
4. jhove.bat now simply uses the Java command rather than requiring
   the user to set up the Java path.
5. JhoveView.jar and jhove (the top level shell script) are now forced
   by ant to be executable so there are no mistakes.
6. Warning message given on invalid buffer size string, and minimum
   buffer size is 1024.
7. Configuration file code for adding handlers and giving init strings
   to modules was an awful mess that never could have worked.
   Major repairs done.

AIFF MODULE

1. If an AIFF file was found to be little-endian, the module instance
   would stay in little-endian mode for all subsequent files. This
   has been fixed.

TIFF MODULE

1. TIFF files that had strip or tile offsets but no corresponding byte
   counts were throwing an exception all the way to the top level. Now
   they're correctly being reported as invalid.

XML MODULE

1. Cleaned up reporting of schemas, Added some small classes to replace
   the use of string arrays for information structures. Made URI comparison
   for local schema parameter case-independent. Resolved conflict between
   "s" and "schema" parameters.

WAVE MODULE

1. Some uncaught exceptions caused the module to throw all the way
   back to JhoveBase and not report any result for certain defective
   files. These now report the file as not well-formed.

JHOVE 1.8

GENERAL

1. Jhove.java and JhoveView.java now get their version information from
   JhoveBase.java. Before it was redundantly kept in three places, and
   sometimes they didn't all get updated for a new release. Like in 1.8.
2. ConfigWriter was in the package edu.harvard.hul.ois.jhove.viewer, which

   by ant to be executable so there are no mistakes.

JHOVE 1.7

GENERAL

1. JHOVE 1.7, as well as future releases unless noted otherwise, is
   released independently of Harvard under the GNU General Public License.
2. JHOVE now will tell you where it was looking for the config file if it
   can't open it. This should help debug configuration problems.

XML HANDLER

1. Changes to XmlHandler.java and NisoImageMetadata.java to correct invalid MIX
   2.0 XML output in the value of grayResponseUnit. It was previously writing
   integers (as in 1.0) rather than the expected enumerated strings.

PDF MODULE

1. A situation that caused an infinite loop and eventual memory exhaustion
   processing in some PDF files with malformed literals has been fixed.
