-----------------
non-noisy when a race steals the message being considered.
JH/05 If main configuration option tls_certificate is unset, generate a
- selfsigned certificate for inbound TLS connections.
+ self-signed certificate for inbound TLS connections.
JH/06 Bug 165: hide more cases of password exposure - this time in expansions
in rewrites and routers.
JH/24 Bug 1832: Log EHLO response on getting conn-close response for HELO.
-JH/25 Decoding ACL controls is now done using a binary search; the sourcecode
+JH/25 Decoding ACL controls is now done using a binary search; the source code
takes up less space and should be simpler to maintain. Merge the ACL
condition decode tables also, with similar effect.
PP/02 Unbreak build via pkg-config with new hash support when crypto headers
are not in the system include path.
+JH/31 Fix longstanding bug with aborted TLS server connection handling. Under
+ GnuTLS, when a session startup failed (eg because the client disconnected)
+ Exim did stdio operations after fclose. This was exposed by a recent
+ change which nulled out the file handle after the fclose.
+
+JH/32 Bug 1909: Fix OCSP proof verification for cases where the proof is
+ signed directly by the cert-signing cert, rather than an intermediate
+ OCSP-signing cert. This is the model used by LetsEncrypt.
+
+JH/33 Bug 1914: Ensure socket is nonblocking before draining after SMTP QUIT.
+
+HS/01 Fix leak in verify callout under GnuTLS, about 3MB per recipient on
+ an incoming connection.
+
+HS/02 Bug 1802: Do not half-close the connection after sending a request
+ to rspamd.
+
+HS/03 Use "auto" as the default EC curve parameter. For OpenSSL < 1.0.2
+ fallback to "prime256v1".
