+
+    BUG/MINOR: config: better detect the presence of the h2 pattern in npn/alpn
+    
+    In 1.8, commit 45a66cc ("MEDIUM: config: ensure that tune.bufsize is at
+    least 16384 when using HTTP/2") tried to avoid an annoying issue making
+    H2 fail when haproxy is built with default buffer sizes smaller than 16kB,
+    which used to be the case for a very long time. Sadly, the test only sees
+    when NPN/ALPN exactly match "h2" and not when it's combined like
+    "h2,http/1.1" nor "http/1.1,h2". We can safely use strstr() there because
+    the string is prefixed by the token's length (0x02) which is unambiguous
+    as it cannot be part of any other token.
+    
+    This fix should be backported to 1.8 as a safety guard against bad
+    configurations.

+
+    BUG/MEDIUM: Make sure stksess is properly aligned.
+    
+    When we allocate struct stksess, we also allocate memory to store the
+    associated data before the struct itself.
+    As the data can be of different types, they can have different size. However,
+    we need the struct stksess to be properly aligned, as it can do 64bits
+    load/store (including atomic load/stores) on 64bits platforms, and some of
+    them doesn't support unaligned access.
+    So, when allocating the struct stksess, round the size up to the next
+    multiple of sizeof(void *), and make sure the struct stksess itself is
+    properly aligned.
+    Many thanks to Paul Martin for investigating and reporting that bug.
+    
+    This should be backported to earlier releases.

+
+    BUG/MEDIUM: hpack: fix encoding of "accept-ranges" field
+    
+    James Brown reported that when an "accept-ranges" header field is sent
+    through haproxy and converted from HTTP/1.1 to H2, it's mis-encoded as
+    "accept-language". It happens that it's one of the few very common header
+    fields encoded using its index value and that this index value was misread
+    in the spec as 17 instead of 18, resulting in the wrong name being sent.
+    Thanks to Lukas for spotting the issue in the HPACK encoder itself.
+    
+    This fix must be backported to 1.8.
