- * 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:

-
-Runtime Statistics:

- * 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:

-
-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.
