This file describes how to update from earlier versions of analog to 1.91beta.
It doesn't describe new features -- those are in the Readme -- but old
features that you can no longer use. As far as possible when I add new options,
I make the old options still work: but sometimes I need to do something a
completely different way and abolish the old options.

Upgrading from 1.9beta's
------------------------
Use configuration commands REQINCLUDE and LINKINCLUDE instead of REQTYPE,
PAGELINKS and +R. (There are no headerfile equivalents).
(Also, not so many things are now pages by default).

Upgrading from 1.2's and earlier
--------------------------------
Use *MINREQS and *MINBYTES instead of *FLOOR.
Use *INCLUDE and *EXCLUDE instead of *ONLY and *IGNORE.
+1, +c, +f, +F, +G, +H and BACKGROUND removed or given new meanings.
Options to +d, +D, +h, +i, +m, +o, +r, +S and +W changed.
Syntax for wild alias matching changed.
Use *SORTBY REQUESTS or BYTES instead of *SORTBY BYREQUESTS or BYBYTES
Configuration files and commandline arguments now read in a different order.
The default configuration file now read unless explicitly excluded with -G.
