New this version ================ -This is a minor bug-fix and feature release since version 0.7.3, -released Apr 4 2009. Notable changes this version: - -- Improved handling of UTF-8 characters. The new code is *not* backwards - compatible by default; see "Upgrading" below for instructions on - converting existing databases to the correct character set. -- Unroll joins for large queries. This greatly enhanced database - performance -- up to 50x for some queries -- at the expense of making - an extra DB hit for some queries. -- Added an optional plugin to use WikiHashtags - (http://hashtags.wikia.com/) for the sidebar on hashtag pages. -- Optimized Twitter friend synchronization. -- Better error handling for Ajax posting of notices, including - HTTP errors and timeouts. -- Experimental Comet plugin -- supports the cometd and the Bayeux - protocol. Using this plugin, you can show "real time" updates on the - public and tag pages. However, server configuration is complex. -- If queues are enabled, update inboxes and memcached off-line. Speeds - up posting considerably. -- Correctly shorten links posted through XMPP. -- <link> elements for pagination, supported by some browsers like Opera. -- Corrected date format in search API. -- Made the public XRDS file work correctly. +This is a major feature release since version 0.7.4, released May 31 +2009. Notable changes this version: + +- Support for a hosted service (status network). Multiple sites can + share the same codebase but use different databases. +- OEmbed. Links to pages that support OEmbed (http://www.oembed.com/) + become popup links, and the media are shown in a special lightbox. +- File attachments. Users can attach files of the size and type approved + by an administrator, and a shortened link will be included in the + notice. +- Related notices are organized into conversations, with each reply a + branch in a tree. Conversations have pages and are linked to from each + notice in the conversation. +- User designs. Users can specify colours and backgrounds + for their profile pages and other "personal" pages. +- Group designs. Group administrators can specify similar designs for + group profiles and related pages. +- Site designs. Site authors can specify a design (background and + colors) for the site. +- New themes. Five new themes are added to the base release; these show + off the flexibility of Laconica's theming system. +- Statistics. Public sites will periodically send usage statistics, + configuration options, and dependency information to Laconica dev site. + This will help us understand how the software is used and plan future + versions of the software. +- Additional hooks. The hooks and plugins system introduced in 0.7.x was + expanded with additional points of access. +- Facebook Connect. A new plugin allows logging in with Facebook Connect + (http://developers.facebook.com/connect.php). +- A session handler. A new optional session handler class to manage PHP + sessions reliably and quickly for large sites. +- STOMP queuing. Queue management for offline daemons has been + abstracted with three concrete instances. A new interface that should + work with STOMP servers like ActiveMQ and RabbitMQ is available, which + should make things scale better. +- Group block. Group admins can block users from joining or posting to + a group. +- Group aliases. Groups can be referred to with aliases, additional + names. For example, "!yul" and "!montreal" can be the same group. +- Bidirectional Twitter bridge. Users can read the tweets their Twitter + friends post on Twitter. +- Adaptation of WordPress.com Terms of Service (http://en.wordpress.com/tos/) + as default TOS for Laconica sites. +- Better command-line handling for scripts, including standard options + and ability to set hostname and path from the command line. +- Many, many bug fixes.
