 Changes in version 0.2.7.5- 2015-11-??
   XXXX WRITE A BLURB XXXX
 
+  o New system requirements:
+    - Tor no longer includes workarounds to support Libevent versions
+      before 1.3e. Libevent 2.0 or later is recommended. Closes
+      ticket 15248.
+    - Tor no longer supports copies of OpenSSL that are missing support
+      for Elliptic Curve Cryptography. (We began using ECC when
+      available in 0.2.4.8-alpha, for more safe and efficient key
+      negotiation.) In particular, support for at least one of P256 or
+      P224 is now required, with manual configuration needed if only
+      P224 is available. Resolves ticket 16140.
+    - Tor no longer supports versions of OpenSSL before 1.0. (If you are
+      on an operating system that has not upgraded to OpenSSL 1.0 or
+      later, and you compile Tor from source, you will need to install a
+      more recent OpenSSL to link Tor against.) These versions of
+      OpenSSL are still supported by the OpenSSL, but the numerous
+      cryptographic improvements in later OpenSSL releases makes them a
+      clear choice. Resolves ticket 16034.

   o Major features (controller):
     - Add the ADD_ONION and DEL_ONION commands that allow the creation
       and management of hidden services via the controller. Closes

       vary freely. Implements part of ticket 12498.
     - Microdescriptors now include Ed25519 identity keys. Implements
       part of ticket 12498.
+    - Add a --newpass option to allow changing or removing the
+      passphrase of an encrypted key with tor --keygen. Implements part
+      of ticket 16769.
+    - Add a new OfflineMasterKey option to tell Tor never to try loading
+      or generating a secret Ed25519 identity key. You can use this in
+      combination with tor --keygen to manage offline and/or encrypted
+      Ed25519 keys. Implements ticket 16944.
+    - On receiving a HUP signal, check to see whether the Ed25519
+      signing key has changed, and reload it if so. Closes ticket 16790.

+      so many of these!
 
-  o Major features (Ed25519 keys, keypinning):
-    - The key-pinning option on directory authorities is now advisory-
-      only by default. In a future version, or when the AuthDirPinKeys
-      option is set, pins are enforced again. Disabling key-pinning
-      seemed like a good idea so that we can survive the fallout of any

     - Improve the runtime speed of Ed25519 signature verification by

     - Improve the speed of Ed25519 operations and Curve25519 keypair
       generation when built targeting 32 bit x86 platforms with SSE2

   o Major features (Hidden services):
+    - Hidden services, if using the EntryNodes option, are required to
