ChangeLog

* Bodie-0.4.1-HIPPY-stable

This releases yields an enterprise-ready version of the software, with
solid behavior, many bugfixes, and more features.

- Better ranking out of the P2P collaborative filter.

- Improved multithreaded behavior.

- Support for CORS.

* Bodie-0.4.0-HIPPY-stable

This release is a milestone, bringing a new API and the ability to
post search results directly onto a P2P ring of seeks machines.

- Introduces a new HTTP REST API,
  http://seeks-project.info/wiki/index.php/API-0.4.0
  Compatibility is ensured with earlier API.

- Ability to post search results to a set of queries. This allows to
  attach any result to any query, not relying on any underlying search
  engine.

- Introduces a seeks CLI to interact from the command line with a
  remote seeks node.

- Adds the ability for a local node to cross-post its recommended
  results to a public Seeks node, so that they are made available to
  others.

- Adds an XSL-serializer plugin that allows to craft XML output formats
  from XSL templates.
	
- 'hot reload' of configuration changes.

- Improved logging of operations.
	
- Fixes for compiling under FreeBSD & Haiku.
	
- New API parameter to control stopwords filtering.

- added configurable support for large (> 2Gb) size user databases.
	
- Many bug fixes and improvements.

* Bodie-0.3.5a-HIPPY-stable

This sub-release mainly fixes several memory leaks.

- Fixes leak in P2P client batch query call.

- Various comments and error logs improvements.

- Various unit tests cleanups.
	
* Bodie-0.3.5-HIPPY-stable

This release brings  improvements to the peer-to-peer search, fixes
a few bugs, and adds functionalities to Seeks.

- Fixes a computational blowup when expanding queries in P2P search.

- Improved detection of dead peers and their monitoring.

- Added default support for Delicious as a feed.

- Added support for Wordpress search results as a feed.

- Added support for Redmine search results as a feed.

- Fixed a bad encoding of some result titles.

- Fix to the Bing result parser.

  script. When set to 'no' it allows to disable all personalization
  features, turning Seeks into a generic meta-search engine.

- An embryo of a no-tracking plugin, that implements HTTP header
  monitoring for avoiding smart tracking of users (e.g. through the
  'Last-Modified' header, ...).

- Fixes to the JSON output.

- Many bug fixes.

* DiAngelo-0.3.4-HIPPY-stable

First release with peer-to-peer activated as default. Every Seeks node
defines a list of Seeks peers to work with. This list defines a
ring of trusted peers. In future versions, the list will be updated
automatically, before a DHT takes over.

- Pure Seeks results: results now include data coming from the Seeks
  network (other peers) and not exclusively from feeds and search
  engines in the pipe.

- Default UI now includes peer information and recommendations.
	
- Implements three P2P call types over HTTP: per-key db access using Tokyo
  Tyrant, query fragment key extraction from Seeks node directly, and
  'batch' P2P query calls that fetch the whole halo of similar queries
  from a distant Seeks node (default).

- Automatic detection and testing of dead peers. Dead peers are marked back as
  alive when they are confirmed to operate correctly.
	
- libevent-2.x support is now default, see
http://sourceforge.net/mailarchive/forum.php?thread_name=20110701064850.GA1476%40hyperion.musicophages&forum_name=seeks-users

- new threaded and interleaved calls to feeds and remote Seeks peers.

- new threaded collaborative filter, with improved local filtering (local
  user control on all results, including those coming from other peers,
  avoids spam or preferences to be overriden).
	
- Many leaks and bug fixes.

- Added special flag to disable OpenCV, as the library seems partly broken
  on Debian testing & sid. See:
http://sourceforge.net/mailarchive/forum.php?thread_name=20110701091640.GA3016%40hyperion.musicophages&forum_name=seeks-users
	
* DiAngelo-0.3.3-SOLO-stable

- Reworked parser and feeds / search engines connection. Allows using the
  same parser over several feeds. Each feed can be accessed independently
  from the API.

- Added support for the following result formats: opensearch (ATOM & RSS),
  dokuwiki and mediawiki.
	
- Slightly improved personalization over halos of similar queries.
	
- Few bug fixes, on personalization and on parsers.

- User db optimization is now optional.

- Improved exception model and handling in all plugins.

- Added info API call to HTTP server plugin.

- Many fixes to JSON search output.

- Support for remote user database, for personalization and other means.
  This allows to deport the user database away from the Seeks node itself.
  It is the first step towards enabling of a mixture of remote user
  profiles, in forthcoming version.

- Personalization using remote user database.

- Added new user db remote service plugin (udb-service) to serve user
  database records remotely, over HTTP.

- Added support for Tokyo Tyrant.
 
	
* DiAngelo-0.3.2-SOLO-stable

  user feedback that is taken into account in ranking and recommendation.

- Several bug fixes, from language detection to missing results from search
  engine parsers.
