+
+Version 0.11.0
+--------------
+
+Security:
+
+ * Fixed CVE-2010-0009: Apache CouchDB Timing Attack Vulnerability.
+ * Added default cookie-authentication and users database.
+ * Added Futon user interface for user signup and login.
+ * Added per-database reader access control lists.
+ * Added per-database security object for configuration data in validation
+   functions.
+ * Added proxy authentication handler
+
+HTTP Interface:
+
+ * Provide Content-MD5 header support for attachments.
+ * Added URL Rewriter handler.
+ * Added virtual host handling.
+
+View Server:
+
+ * Added optional 'raw' binary collation for faster view builds where Unicode
+   collation is not important.
+ * Improved view index build time by reducing ICU collation callouts.
+ * Improved view information objects.
+ * Bug fix for partial updates during view builds.
+ * Move query server to a design-doc based protocol.
+ * Use json2.js for JSON serialization for compatiblity with native JSON.
+ * Major refactoring of couchjs to lay the groundwork for disabling cURL
+   support. The new HTTP interaction acts like a synchronous XHR. Example usage
+   of the new system is in the JavaScript CLI test runner.
+
+Replication:
+
+ * Added option to implicitly create replication target databases.
+ * Avoid leaking file descriptors on automatic replication restarts.
+ * Added option to replicate a list of documents by id.
+ * Allow continuous replication to be cancelled.
+
+Storage System:
+
+ * Adds batching of multiple updating requests, to improve throughput with many
+   writers. Removed the now redundant couch_batch_save module.
+ * Adds configurable compression of attachments.
+
+Runtime Statistics:
+
+ * Statistics are now calculated for a moving window instead of non-overlapping
+   timeframes.
+ * Fixed a problem with statistics timers and system sleep.
+ * Moved statistic names to a term file in the priv directory.
+
+Futon:
+
+ * Added a button for view compaction.
+ * JSON strings are now displayed as-is in the document view, without the escaping of
+   new-lines and quotes. That dramatically improves readability of multi-line
+   strings.
+ * Same goes for editing of JSON string values. When a change to a field value is
+   submitted, and the value is not valid JSON it is assumed to be a string. This
+   improves editing of multi-line strings a lot.
+ * Hitting tab in textareas no longer moves focus to the next form field, but simply
+   inserts a tab character at the current caret position.
+ * Fixed some font declarations.
+
+Build and System Integration:
+
+ * Updated and improved source documentation.
+ * Fixed distribution preparation for building on Mac OS X.
+ * Added support for building a Windows installer as part of 'make dist'.
+ * Bug fix for building couch.app's module list.
+ * ETap tests are now run during make distcheck. This included a number of
+   updates to the build system to properly support VPATH builds.
+ * Gavin McDonald setup a build-bot instance. More info can be found at
+   http://ci.apache.org/buildbot.html
+

+
+Version 0.8.1-incubating
+------------------------
+
+Database Core:
+
+ * Fix for replication problems where the write queues can get backed up if the
+   writes aren't happening fast enough to keep up with the reads. For a large
+   replication, this can exhaust memory and crash, or slow down the machine
+   dramatically. The fix keeps only one document in the write queue at a time.
+ * Fix for databases sometimes incorrectly reporting that they contain 0
+   documents after compaction.
+ * CouchDB now uses ibrowse instead of inets for its internal HTTP client
+   implementation. This means better replication stability.
+
+HTTP Interface:
+
+ * Fix for chunked responses where chunks were always being split into multiple
+   TCP packets, which caused problems with the test suite under Safari, and in
+   some other cases.
+ * Fix for an invalid JSON response body being returned for some kinds of
+   views. (COUCHDB-84)
+ * Fix for connections not getting closed after rejecting a chunked request.
+   (COUCHDB-55)
+ * CouchDB can now be bound to IPv6 addresses.
+ * The HTTP `Server` header now contains the versions of CouchDB and Erlang.
+
+JavaScript View Server:
+
+ * Sealing of documents has been disabled due to an incompatibility with
+   SpiderMonkey 1.9.
+ * Improve error handling for undefined values emitted by map functions.
+   (COUCHDB-83)
+
+Build and System Integration:
+
+ * The `couchdb` script no longer uses `awk` for configuration checks as this
+   was causing portability problems.
+ * Updated `sudo` example in `README` to use the `-i` option, this fixes
+   problems when invoking from a directory the `couchdb` user cannot access.
+
+Futon:
+
+ * The view selector dropdown should now work in Opera and Internet Explorer
+   even when it includes optgroups for design documents. (COUCHDB-81)
+
+Version 0.8.0-incubating
+------------------------
+
+Database Core:
+
+ * The view engine has been completely decoupled from the storage engine. Index
+   data is now stored in separate files, and the format of the main database
+   file has changed.
+ * Databases can now be compacted to reclaim space used for deleted documents
+   and old document revisions.
+ * Support for incremental map/reduce views has been added.
+ * To support map/reduce, the structure of design documents has changed. View
+   values are now JSON objects containing at least a `map` member, and
+   optionally a `reduce` member.
+ * View servers are now identified by name (for example `javascript`) instead of
+   by media type.
+ * Automatically generated document IDs are now based on proper UUID generation
+   using the crypto module.
+ * The field `content-type` in the JSON representation of attachments has been
+   renamed to `content_type` (underscore).
+
+HTTP Interface:
+
+ * CouchDB now uses MochiWeb instead of inets for the HTTP server
+   implementation. Among other things, this means that the extra configuration
+   files needed for inets (such as `couch_httpd.conf`) are no longer used.
+ * The HTTP interface now completely supports the `HEAD` method. (COUCHDB-3)
+ * Improved compliance of `Etag` handling with the HTTP specification.
+   (COUCHDB-13)
+ * Etags are no longer included in responses to document `GET` requests that
+   include query string parameters causing the JSON response to change without
+   the revision or the URI having changed.
+ * The bulk document update API has changed slightly on both the request and the
+   response side. In addition, bulk updates are now atomic.
+ * CouchDB now uses `TCP_NODELAY` to fix performance problems with persistent
+   connections on some platforms due to nagling.
+ * Including a `?descending=false` query string parameter in requests to views
+   no longer raises an error.
+ * Requests to unknown top-level reserved URLs (anything with a leading
+   underscore) now return a `unknown_private_path` error instead of the
+   confusing `illegal_database_name`.
+ * The Temporary view handling now expects a JSON request body, where the JSON
+   is an object with at least a `map` member, and optional `reduce` and
+   `language` members.
+ * Temporary views no longer determine the view server based on the Content-Type
+   header of the `POST` request, but rather by looking for a `language` member
+   in the JSON body of the request.
+ * The status code of responses to `DELETE` requests is now 200 to reflect that
+   that the deletion is performed synchronously.
+
+JavaScript View Server:
+
+ * SpiderMonkey is no longer included with CouchDB, but rather treated as a
+   normal external dependency. A simple C program (`_couchjs`) is provided that
+   links against an existing SpiderMonkey installation and uses the interpreter
+   embedding API.
+ * View functions using the default JavaScript view server can now do logging
+   using the global `log(message)` function. Log messages are directed into the
+   CouchDB log at `INFO` level. (COUCHDB-59)
+ * The global `map(key, value)` function made available to view code has been
+   renamed to `emit(key, value)`.
+ * Fixed handling of exceptions raised by view functions.
+
+Build and System Integration:
+
+ * CouchDB can automatically respawn following a server crash.
+ * Database server no longer refuses to start with a stale PID file.
+ * System logrotate configuration provided.
+ * Improved handling of ICU shared libraries.
+ * The `couchdb` script now automatically enables SMP support in Erlang.
+ * The `couchdb` and `couchjs` scripts have been improved for portability.
+ * The build and system integration have been improved for portability.
+
+Futon:
+
+ * When adding a field to a document, Futon now just adds a field with an
+   autogenerated name instead of prompting for the name with a dialog. The name
+   is automatically put into edit mode so that it can be changed immediately.
+ * Fields are now sorted alphabetically by name when a document is displayed.
+ * Futon can be used to create and update permanent views.
+ * The maximum number of rows to display per page on the database page can now
+   be adjusted.
+ * Futon now uses the XMLHTTPRequest API asynchronously to communicate with the
+   CouchDB HTTP server, so that most operations no longer block the browser.
+ * View results sorting can now be switched between ascending and descending by
+   clicking on the `Key` column header.
+ * Fixed a bug where documents that contained a `@` character could not be
+   viewed. (COUCHDB-12)
+ * The database page now provides a `Compact` button to trigger database
+   compaction. (COUCHDB-38)
+ * Fixed portential double encoding of document IDs and other URI segments in
+   many instances. (COUCHDB-39)
+ * Improved display of attachments.
+ * The JavaScript Shell has been removed due to unresolved licensing issues.
