You can toggle between previous (standard) and new (generation) strategy at PerformanceMemory_p.html.
The generation memory strategy is implemented with the objective of running more robust
but with the cost of early stopping some tasks (eg. dht) while running low on memory.
This new strategy does respect the generational way a heap is organized on most used jvms.
These changes run fine on my 3 peers for weeks now, but as I'm human, I may fail.
Please be carefull using generation memory strategy and report errors by naming
OS, jvm and java_args.

The YaCy freeworld network used in this network definition, minor enhancements for the feed of MetaGer were integrated.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes

- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

YaCy supports now the storage to remote solr indexes.
More federated storage (and search) methods may follow.
The remote index scheme is the same as produced by the SolrCell; see
http://wiki.apache.org/solr/ExtractingRequestHandler
Because this default scheme is used, the default example scheme can be used as solr configuration
This is also the same scheme that solr uses if documents are imported with apache tika.
federated solr storage is switched off by default.
To use this, do the following:
- set federated.service.solr.indexing.enabled = true
- download solr from http://www.apache.org/dyn/closer.cgi/lucene/solr/
- extract the solr (3.1) package, 'cd example' and start solr with 'java -jar start.jar'
- start yacy and then start a crawler. The crawler will fill both, YaCy and solr indexes.
- to check whats in solr after indexing, open http://localhost:8983/solr/admin/
Until now it is not possible to use the solr index to search with YaCy in that solr index.
This functionality is now available for two reasons:
1) to compare the functionality of Solr and YaCy and to compare the search speed
2) to use YaCy as a search appliance for people who need a crawler or other source harvesting methods
that YaCy provides (like dublin core reading, wikimedia dump reading, rss feed reader etc) if people still
want to use solr instead of YaCy.

- removed configuration button for 'search only for admin' from index.html and added this to ConfigPortal
- added configuration of link verification options (iffresh, cacheonly, nocache, ifexist) to ConfigPortal
- added configuration of navigation options to ConfigPortal
- added an option to switch off automatic index cleaning in case that a link verification method fails

This has two aspects: the user who searches may want to increase these values to get more results and more load on the remote side and the user of the server which is accessed for this search may want to restrict the load. Both sides can now be configured. The server-site maximum load parameters are defined by a network definition and the client-side search request load can be defined by each user individually but when the remote search is done the requested service is limited to the network definition.
You can find now in the network definition file:
network.unit.remotesearch.maxcount and network.unit.remotesearch.maxtime
and in the yacy.conf file:
remotesearch.maxcount and remotesearch.maxtime
There is currently no web interface to define the client-side remote search attributes, please set them manually

- filtering out too old peers when reading seed lists (limit is now 240 minutes)
- added concurrent host names resolving in front of the http client because the http client uses the java built-in DNS resolve which is not multithreading-safe (i have seen deadlocks in thread dumps showing that this bug in jdk is still there)

- if YaCy is started with the option -gui, it is not in headless mode. Then the java 1.6 browse method is used if all other methods fail
- in linux, the path /etc/alternatives/www-browser is used if no firefox is installed

Please see new coments in yacy.network.freeworld.unit for details of the new DHT selection methods.
The number of maximum peers is now not fixed to a specific number but may increase with
- the partition exponent
- the number of redundant peers
- the robinson burst percentage
- the multiword burst percentage
The maximum can then be the number of senior peers (all visible peers).

- some restructuring of the document counting and logging structures was necessary
- better abstraction of CrawlProfiles
- added deletion of logs to the index deletion option (if the index is deleted using the servlets) which is necessary to reset the domain counters for the page limitation
- more refactoring to get the LibraryProvider more clean
- some refactoring of the Condenser class

- the own seed file gets the lead for storage of the peer name
- exchanged default peer name generation method with one that does not use the local ip
- default peer names are now strings starting with '_anon'
- added another switch to suppress forwarding to ConfigBasic if the name was already changed
- replaced all usages of the yacy.conf peerName with access to the local seed
- changes to the peer name are now applied directly and not after the next peer ping

- this recording is then used to redirect from the Status.html page to BasicConfig in case that servlet was never submitted
- this acts as an addition to the new default pop-up page 'index.html' which offers an administration link to Status.html. For a first-time user this then redirects directly to the former start page BasicConfig.html

- adjusted top menu on search page (shows less stuff and now also the network graphics)
- adjusted the network page (looks better in when showing no other navigation on top)

- words are now not deleted from the search index automatically if index receive is switched off
- a flag in the network definition defines if this feature is switched on at all
- the search filter for not-found word references is switched off for server-side remote searches
