-    BUG/MINOR: stream: init variables when the list is empty
-    
-    We need to call vars_init() when the list is empty otherwise we
-    can't use variables in the response scope. This regression was
-    introduced by cda7f3f5 (MINOR: stream: don't prune variables if
-    the list is empty).
-    
-    The following config reproduces the issue:
-    
-     defaults
-       mode http
-    
-     frontend in
-       bind *:11223
-       http-request set-var(req.foo) str("foo")  if { path /bar }
-       http-request set-header bar %[var(req.foo)]  if { var(req.foo) -m found }
-       http-response set-var(res.bar) str("bar")
-       http-response set-header foo %[var(res.bar)] if { var(res.bar) -m found }
-       use_backend out
-    
-     backend out
-       server s1 127.0.0.1:11224
-    
-     listen back
-       bind *:11224
-       http-request deny deny_status 200

-    BUG/MINOR: contrib/prometheus-exporter: Use HTX errors and not legacy ones
-    
-    This bug was introduced when the commit 32d634f1 ("MINOR:
-    contrib/prometheus-exporter: filter exported metrics by scope") was backported
-    to 2.0.
-    
-    In 2.0, Error chunks exist in raw format (http_err_chunks[]) and in HTX format
-    (htx_err_chunks[]). Prometheus exported only supports the HTX. So error must not
-    be reported using the raw chunks.
-    
-    This fix is specific to 2.0. No backport needed.

-    BUG/MINOR: contrib/prometheus-exporter: decode parameter and value only
-    
-    we were decoding all substring and then parsing; this could lead to
-    consider & and = in decoding result as delimiters where it should not.
-    this patch reverses the order by first parsing and then decoding each key
-    and value separately.
-    
-    we also stop parsing after number sign (#).
-    
-    This patch should be backported to 2.1 and 2.0
