Features:
---------
+
+ * Feeds are now by default updated in parallel for a huge speedup in performance.
+ * Added hotkeys to sfeed_html to toggle showing only new items (n key) and
+ focusing the menu (s key) or items (i key) using a tiny bit of
+ javascript.
+ * Auto-detect XML encoding.
+
+
* Added sfeed_frames, a formatting program to output feeds as a HTML file with
frames. It's optimized to look good in older browsers that don't necesarily
- support CSS or modern HTML like links. See the man page for more details.
+ support CSS or modern HTML, like links. See the man page for more details.
* Removed the dependency on libexpat, using a custom XML parser (xml.*),
this parser is also non-validating, it will not check the XML for errors
or stop parsing if it contains errors (which is good).

-
-If you execute sfeed_update and see the error:
-
- "sfeed: error parsing xml not well-formed (invalid token) at line <linenumber>
- column <column>"
-
-it's possible sfeed is trying to parse a feed which is non-UTF8 encoded. You can
-specify the encoding in your sfeedrc file so it will be converted to UTF-8
-using iconv, for example for iso-8859-1 change:
-
- feed "feedname" "feedurl" "baseurl"
-
-to:
-
- feed "feedname" "feedurl" "baseurl" "iso-8859-1"
