Versie 4.0 van Usenet Explorer is uitgekomen. Met dit programma kunnen bestanden van Usenet worden gedownload. Usenet Explorer kenmerkt zich onder meer door een laag processor- en geheugengebruik, en zeer uitgebreide mogelijkheden, wat het voor beginnende gebruikers misschien minder geschikt maakt. Nog maar kort geleden is versie 3.6 verschenen, maar aan 4.0 werd al veel langer parallel gewerkt. In versie 4.0 is onder meer het geheugengebruik verder verminderd, laadt het nieuwsgroepen sneller in en kunnen meer message-id's worden opgeslagen. Deze veranderingen hebben overigens wel tot gevolg dat de database uit versie 3.6 of ouder niet meer compatibel is.
Changes in version 4.0
- Sets were introduced which result in significantly lower RAM usage and faster newsgroup load. See Sets description for details.
- The size limit of the per group cnt.dat file which contains message-ids and other load on demand data has been increased from 32GB to 256GB.
- When the program is not exited properly - the newsgroups maintain integrity and don't need repair.
- To provide those new features - the database has slightly different format, existing database is converted on per newsgroup basis, see download page for details.
- The option edit menu -> properties -> general, Sets, "Sets only as a whole in custom collections", enabled by default. Instead of individual files the containing set will be added to the custom collection. The option also adjusts custom collections in this way on newsgroup opening or when converting from versions without set support.
- Custom collections improvements: the 'set as current' collection now persists between sessions; additional menu option to add files to 'set as current' collection directly without the dialog box; when entering a custom collection the 'set as current' collection check box in the dialog box is checked.
- Significantly improved preserving view position when toggling threads/sets/collections.
- Sets or collections state more precisely reflect their containing files states.
- Added help explanations regarding max.groups and header tasks RAM limit settings in edit menu -> properties -> tasks, see the '?' buttons near the options.
