the YaCy client treats disconnections during data transmissions as error and discards all data transmitted so far
this did not happen so far until I removed a delay time at the end of the daemon session which prevented this case.
To fix this problem, disconnections during transmissions are not treated as error now, which means that end-of-transmissions
with sudden disconnections are not a cause for peer diconnections any more. To be nice to non-updated peers, the sleep time
at the end of server sessions is also re-enabled.

search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

- different handling of link quotation
- different handling of link normalization
- enhanced html/unicode en/de-coding

- within this context: generalized date format handling
- extended Update interface:
* a version lookup can be triggered manually
* a complete lookup + download + re-boot process can be triggered with one click

** kann das mal jemand auf seiner linux-platform testen **
** und feed-back geben ob der restart funktionier ? **

- added new download-option for releases on the status page
still mising:
- thomas-style restart for linux/mac
- untar/gunzip on shell basis
(comes next)

- added chunked file transfer for non-yacy clients
- SSIs are streamed using chunked transfer, partly delivered pages can be seen in browser before transmission is finished
- added client-side network unit identification
- cleaned up code

- hopefully fixed logging of GCs (in order to avoid things like "performed necessary GC, freed 18014398509481565 KB (requested/available/average: 4096 / 1631 / 2957 KB)") with the help of KoH

we will provide two different releases in the future, one standard release and one 'pro'-release.
the 'pro'-release contains all additional parsers AND has different default performance values.
The pro-version differs therefore from the previous 'all'-version by this default values.
The pro-configuration is automatically choosen if the libx-folder exists. If a version is once initialized, its configuration stays independently from an existing libx folder.
The ant targets had been changed. There are now 3 different targets to create standard and pro-releases, and one target to upgrade:
- dist: creates a standard release (only, no libx target any more)
- distPro: creates a pro-release (includes the libx)
- distExt: creates a libx-release which includes the libx-folder only. It may be used to upgrade from standard to pro
Furthermore, the naming of 'dev'-releases had been removed.

- all requests to the own httdp can now be listed in the access tracker menu

- fixed wrong XML output if no peers are known in Network.xml
- simplified parsing of table properties in wikiCode and ZTableToken
- reimplemented GC heuristics. They are needed to constantly ensure that an amount of free memory is available which is higher than Java's max. limit for performing a Full GC (please use serverMemory.request(long, boolean) rather than serverMemory.available(long, boolean) to provide data for averaging over the last GCs)

- all web page parsing operations will now increase a web structure file
- the file is computed in memory and dumped at shutdown-time to PLASMASB/webStructure.map in readable form (not a database)
- the file can be used externally to analyse the link structure of the crawled pages
- the web structure can also be retrieved using a xml-interface at http://localhost:8080/xml/webstructure.xml
- the short-term purpose is the computation of a link-graph image (before linuxtag!)
- a long-term purpose could be a decentralized computation of the citation rank

- added 7zip parser
- added 'text/sgml' to realtime parseable mimetypes (sometimes returned by the mime type parser)
- added new cached output stream class, very suitable for parsers because of limited memory
