Great progress, more than four hundred bug fixes and enhancements from
YaCy developers luccioman and reger.

After more than a year we have a huge set of new features, too many to
count them all here. To see a complete list, please open
http://yacy.net/release_notes/YaCy_Release_1_90.html

The main enhancements of this release are: IPv6 routing of Peer-to-Peer
network elements and overall IPv6 enhancements, added self stats logging
(showing the number of peers in the network over time), enhancement of
embedded http server (less loading by browser using expires dates),
document date detection, document snapshots (an optional document
archive created by the crawler), partial updates to solr during
postprocessing and more postprocessing enhancements, new UPNP classes,
updates to many external libraries such as pdf parser and jetty.
Furthermore, there is now a release notes web pages which shows all the
details at http://yacy.net/release_notes/

Release 1.8

In-between release for linuxtag. This will also the last release
supporting java 1.6

Huge update on web site design in YaCy: we are now using bootstrap.css.
A large number of other changes is included as well, most notable an
almost perfect russian localization, many bugfixes and performance
enhancements.

Release 1.68 with a lot of important changes
- replaced homebrew httpd with jetty
- removed jena
- enhanced search quality, remote peer selection, search speed, search
completion etc.
- removed memory leaks and enhanced running in low-memory and low-CPU
environments

Main Release 1.6

Release 1.5

This is the YaCy main release 1.4.
This release includes mainly a deeper Solr integration, much more Solr
fields are filled, Solr has now mutli-core capabilities and a second
core with a webgraph was added (but deactivated for further testing).
The opensearch result writer of the integrated solr has now all the
feateures as the original opensearch result servlet of YaCy had, and the
file search interface "yacyinteractive" now uses this new result writer
instead the old one. The search of that interface is now much, much
faster. The default search functionality has undergone a full re-design
and a lot of testing was done to fix problems with the to-solr
migration. The normal search is now very fast, in portal mode and even
in p2p mode. The ranking was strongly enhanced, there is now a support
for flexible field boosts, boost functions and boost queries. All these
ranking functions had been made editable and there is a new
configuration sevlet for this. Furthermore, there are several ranking
schemas predefined, one for default internet search, one for
sort-by-date and one for intranet search requests, which is triggered
automatically if a site-operator is used. Intranet search ranking rates
deep links higher than shallow which returns more specific document
types. Remote searches are done using the local ranking profile, not the
remote profile. The selection of target peers had been enhanced, now all
robinson peers which have a solr interface are searched using that
interface rather with the old YaCy interface. There should also an
enhancement in indexing speed as there are less requests to the solr for
doing that and index updates are bundled together while forced commits
had been reduced using a new solr 4.1 soft-commit feature. There had
also been fixes to some memory leaks and the overall memory usage should
be lower. Finally, the logging had been renovated and logs are now done
using only the java-logger. All libraries, using different loggin
technology are routed to the java logger using logging gateways. The
complete number of log entries for solr updates had been strongly
reduced since these many logging entries had become a perfomance issue
in 1.3.

Release 1.3

Release 1.2

Release 1.1
Most important about this release is the replacement of the
built-in metadata database with apache solr. Solr is an indexing
framework of its own ant the current implementation uses only a fragemt
of the functionalities that is provided by solr but the embedded solr
server is accessible from outside as a http service as a jetty- or
apache http-driven version of solr does. This interface is now also used
by YaCy using so-called new 'Node' peers which are highly available and
very fast peers in the YaCy p2p network. The solr Schema has a rich
number of metadata fields, where the original number of metadata field
of YaCy is a subset.
YaCy 1.1 is much faster and presents more and more appropriate search
results when doing a more-than-one-word search.

Release_1.04

Release_1.03

Release 1.02

Release_1.01 with many bugfixes from new volunteers!
- ranking should be slightly better since the result page waits a bit
longer until some more than only one remote peer has contributed
- less deadlocks
- scroogle heuristic is switched on by default
- first release out of the new Git repository
