+=== yahns 1.12.4 - rack.hijack and proxy_pass bugfixes / 2016-05-02 19:43 UTC
+
+  This release fixes some resource leaks in uncommonly used parts
+  of yahns as well as including some documentation improvements.
+  No need to upgrade unless you rely on rack.hijack for responses
+  or use the (currently-undocumented) proxy_pass module(*).
+
+  9 non-merge changes since 1.12.3:
+
+        proxy_pass: honor wbuf_persist when ending response
+        proxy_http_response: fix non-terminated fast responses, too
+        test_proxy_pass: test for auto chunking on 1.0 backends
+        wbuf: drop persistence if writing to client fails
+        proxy_http_response: cleanup: avoid redundant setting of "alive"
+        proxy_http_response: do not persist upstream on slow clients
+        proxy_pass: drop resources immediately on errors
+        document Rack::Chunked/ContentLength semi-requirements
+        extras/exec_cgi: document cgit example
