+2008-07-xx  -  PgBouncer 1.2  -  ""
+
+  = Features =
+
+    * Cmdline option (-u) and config param (user=) to support user switching
+      at startup.  Also now pgbouncer refuses to run as root. (Jacob Coby)
+    * More descriptive usage text (-h).  (Jacob Coby)
+    * New database option: connect_query to allow run a query on new
+      connections before they are taken into use.  (Teodor Sigaev)
+    * New config var 'ignore_startup_parameters' to allow and ignore
+      extra paramenters in startup packet.  By default only 'database'
+      and 'user' are allowed, all others raise error.  This is needed
+      to tolerate overenthusiastic JDBC wanting to unconditionally
+      set 'extra_float_digits=2' in startup packet.
+    * Logging to syslog: new parameters syslog=0/1 and
+      syslog_facility=daemon/user/local0.
+    * Less scary online restart (-R)
+      - Move FD loading before fork, so it logs to console and can be canceled by ^C
+      - Keep SHUTDOWN after fork, so ^C would be safe
+      - A connect() is attempted to unix socket to see if anyone is listening.
+        Now -R can be used even when no previous process was running.  If there
+        is previous process, but -R is not used, startup fails.
+    * New console commands:
+      - SHOW TOTALS that shows stats summary (as goes to log) plus mem usage.
+      - SHOW ACTIVE_SOCKETS - like show sockets; but filter only active ones.
+
+  = Less visible features =
+
+    * suspend_timeout - drop stalled conns and long logins. This brings
+      additional safety to reboot.
+    * When remote database throws error on logging in, notify clients.
+    * Removing a database from config and reloading works - all connections
+      are killed and the database is removed.
+    * Fake some parameters on console SHOW/SET commands to be more Postgres-like.
+      That was needed to allow psycopg to connect to console.
+      (client_encoding/default_transaction_isolation/datestyle/timezone)
+    * Make server_lifetime=0 disconnect server connection immidiately
+      after first use.  Previously "0" made PgBouncer ignore server age.
+      As this behaviour was undocumented, there should not be any users
+      depending on it.
+    * Internal improvements:
+      - Packet buffers are allocated lazily and reused.  This should bring
+        huge decrease in memory usage.  This also makes realistic to use
+        big pktbuf with lot of connections.
+      - Lot's of error handling improvements, PgBouncer should now
+        survive OOM situtations gracefully.
+      - Use slab allocator for memory management.
+      - Lots of code cleanups.
+
+  = Fixes =
+
+    * Only single accept() was issued per event loop which could
+      cause connecton backlog when having high amount of connection
+      attempts.  Now the listening socket is always drained fully,
+      which should fix this.
+    * Handle EINTR from connect().
+    * Make configure.ac compatible with autoconf 2.59.
+    * Solaris compatibility fixes (Magne Mæhre)
+
+2007-12-10  -  PgBouncer 1.1.2  -  "The Hammer"
+
+  = Features =
+
+    * Disconnects because of server_lifetime are now separated by
+      (server_lifetime / pool_size) seconds.  This avoids pgbouncer
+      causing reconnect floods.
+
+  = Fixes =
+
+    * Online upgrade 1.0 -> 1.1 problems:
+      - 1.0 does not track server parameters, so they stay NULL
+        but 1.1 did not expect it and crashed.
+      - If server params are unknown, but client ones are set,
+        then issue a SET for them, instead complaining.
+    * Remove temp debug statements that were accidentally left
+      in code on INFO level, so they polluted logs.
+    * Unbroke debian/changelog
+
+  = Cleanup =
+
+    * reorder struct SBuf fields to get better alignment for buffer.
+
+2007-10-26  -  PgBouncer 1.1.1  -  "Breakdancing Bee"
+
+  = Fixes =
+
+  * Server parameter cache could stay uninitialized, which caused
+    unnecessary SET of them.  This caused problem on 8.1 which
+    does not allow touching standard_conforming_strings.
+    (Thanks to Dimitri Fontaine for report & testing.)
+
+  * Some doc fixes.
+  * Include doc/fixman.py in .tgz.
