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.

- 300 ppm is default now (but this is switched off by default; if you switch it on you may want more traffic?)
- better timing for busy queue
- better amount of remote url retrieval
- better time-out values
- better tracking of availability of remote crawl urls
- more logging for result of receipt sending

the home path can now be distinguished between
- data home; the path where the DATA directory is created
- application home; everything else
This will make it possible to store application data on Mac releases within the
~/Library/YaCy
directory; a place where Mac applications write their data.
Similar techniques will be possible for debian and windows.
To use the new data path, YaCy can be started with
-start <data path>
or
-gui <data path>

- move the header framework classes to cora
- move the ARC caching classes to cora
- refactoring of code to call these classes from cora

- the scheduler extends the option for re-crawl timing. Many people misunderstood the re-crawl timing feature because that was just a criteria for the url double-check and not a scheduler. Now the scheduler setting is combined with the re-crawl setting and people will have the choice between no re-crawl, re-crawl as was possible so far and a scheduled re-crawl. The 'classic' re-crawl time is set automatically when the scheduling function is selected
- removed the bookmark-based scheduler. This scheduler was not able to transport all attributes of a crawl start and did therefore not support special crawling starts i.e. for forums and wikis
- since the old scheduler was not aber to crawl special forums and wikis, the must-not-match filter was statically fixed to all bad pages for these special use cases. Since the new scheduler can handle these filters, it is possible to remove the default settings for the filters
- removed the busy thread that was used to trigger the bookmark-based scheduler
- removed the crontab for the bookmark-based scheduler

- now xms is lower than xmx (lets try what happens)
- removed default path for intranet crawl starts to avoid confusion as seen on linuxtag
- added time-out to upnp request (i have a new router which may need that)

- fixes to http file server session handling
- fixes and enhancements to metadata date/time handling

This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.

- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

divided that class into three parts:
- the peers object is now hosted by the plasmaSwitchboard
- the crawler elements are now in a new class, crawler.CrawlerSwitchboard
- the index elements are core of the new segment data structure, which is a bundle of different indexes for the full text and (in the future) navigation indexes and the metadata store. The new class is now in kelondro.text.Segment
The refactoring is inspired by the roadmap to create index segments, the option to host different indexes on one peer.

The old process used a not really efficient way to detect html encoding strings in texts.
All calling methods had been adoped to call the new class in an enhanced way with less parameters.
Many classes in interfaces used a XML encoding only (instead of full html conversion from unicode to html); this behavior was not changed with this commit but should be controlled again since it points out possible XSS leaks

- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)
* hopefully fixed "missing quote" (announcing StringParts as UTF-8)

- added option to set minimum crawl delta for domains in balancer
- added default values to crawl deltas in yacy.init
- added configuration for these deltas in performance queues
- enhanced performance setting computation (more time for indexing queue for a faster flush
- remote crawling is now enabled during local crawling if indexer has space and time for more links
- added database stub for new distributed file system
- refactoring of time computation to get an abstraction level that will be used by a TTL rule in new distributed file system
