Release Notes

This release builds on the previous (2007.3) and provides a few more valuable enhancements that I’ve seen users ask about or find challenging. In addition to all the bullet items of the 2007.3 release there is the following additions:
  • More efficient incremental crawling – the accessor now chunks a container’s URLs with the date/time using the DIRLINK_WITH_TIME ID. In this way accessors won’t even be created by the gatherer if the date is not newer than the last crawl. (see http://msdn.microsoft.com/en-us/library/aa965720.aspx)
  • Container URLs now return a date last modified as well, so if the container has not changed its URLs don’t need to be emitted.
  • Support for custom property data types other than string. It now supports integers, floating point, etc. Just take a look at the PROPVARIANT_UNION structure for a complete list.
  • I’ve cleaned up much of the PROPVARIANT, PROPSPEC, etc code so that its smaller and easier to extend. I’ve also revisited the ‘using’ directives in the interface source files to make them more complete, accurate and documented.
  • I’ve switched FILETIME back to a local structure again, looks like I was mistaken about it being marked for COM visibility in the .NET framework.

At this point I think it’s pretty solid in terms of functionality and layout, let me know if you have any further suggestions.

Please access the new source using the "Source" tab. I haven't modified any of the documentation, so if you still need that please refer to release 2007.2.
As before, good luck and happy crawling!

-John
