Note about --http11 becoming the default for tracd and the consequences for the code

+==== [TracStandalone tracd] and HTTP/1.1 ====
+
+Since 0.11.5, tracd could be used with the `--http11` flag, which would select the use of the HTTP/1.1 protocol and most notably activate Keep-Alive connections. This is now the default behavior in 0.12.
+
+This has some important consequences for plugins which send content directly to the client. They should take care of setting the `Content-Length` header properly, otherwise the browser will simply "hang". 
+
+This means that any:
+{{{
+#!python
+    req.write(content)
+}}}
+must be preceded by a:
+{{{
+#!python
+    req.send_header('Content-Length', len(content))
+}}}
+
+Don't forget to do that for ''any'' data directly sent back to the client, including responses for XHRs (e.g. r8300).
+This requires a some discipline in the coding, but the benefit is a huge performance boost for tracd, so it's well worth the price.
+
+See #8020 for details.
