UPGRADING: IMPORTANT NOTE
-If you are upgrading from mod_proxy_html 2.x (or 1.x), you will need
-some new configuration. You can Include proxy_html.conf from this
-bundle in your httpd.conf (or apache.conf) to use Version 3 as a
-drop-in replacement for Version 2.
+Upgrading from 3.0 or any earlier version, you may need to:
+ (1) Load mod_xml2enc
+ (2) Use the new "ProxyHTMLEnable On" directive in place of
+ Apache's general-purpose filter configuration (such as
+ SetOutputFilter or FilterChain).
+Without these it'll work fine with ASCII or Unicode utf-8,
+but is likely to display characters incorrectly with other
+character encodings.
+If you are upgrading from mod_proxy_html 2.x (or 1.x), you will need
+to configure what HTML elements should be treated as links and events.
+The configuration file "proxy_html.conf" loaded into your httpd.conf
+(or apache.conf, apache2.conf or similar according to packager's whims)
+does this if you're dealing with standard/W3C HTML 4 and/or XHTML 1.
