Important changes in this release include, in no particular order: a brand new installer; much improved GLI compatibility with Java 1.5.0; the ability to import documents exported from DSpace, and vice versa; a smarter HTMLPlug that blocks the images in the HTML files it processes, and no others; new GLI metadata sets: Qualified Dublin Core, NZGLS, AGLS, and RFC 1807; Lucene building support (for real this time!); an improved and much more bandwidth-efficient GLI applet; support for subfields in the Greenstone Editor for Metadata Sets (GEMS); and many many other improvements and bug fixes."
