These sounds like terrific meta-level improvements.
The Jumbo U2 has a new ZIP filename and download URL. U2 users probably
know that the ZIP filename has been based on the U2 version number,
e.g. XYWEB125.ZIP. Now, the filename is simply XYWWEBU2.ZIP; it will
not change, and it will always contain the latest updates. As a result,
the direct download URL will also never change, and you can download
the latest U2 anytime from:
XYWWEBU2.ZIP contains only the essential U2 files: readme-u2.pdf,
XYWWWEB.U2, XYWWWEB.INF, XYWWEBU2.REG (renamed from XYWEB[ver].REG),
REG-READ.ME, and changelog.pdf. The external Windows and DOS programs
used by U2 routines are now collected in a separate ZIP archive,
U2EXTRAS.ZIP, which will be updated as necessary from time to time. The
new extras archive also has a static direct-download URL:
Version numbers will no longer be used, and updates will be identified
by the YYYY-MM-DD release date, the current one being 2016-11-06. The
latest revisions are described in the changelog:
The latest release has new frames U2UPD, to update to the latest U2
release, and SETPORT, implementing Wengier's new SETPORT command.
Command DX SETPORT/?<Helpkey> to view usage details.
