12 March 2001: 3.1.12

	* cachelogd now accepts port to listen from -pXXX
	  command line argument.
	* Crash in UdmAddURL() function has been fixed.
	* CPU usage overhead bug in cachelogd has been fixed.
	* Memory leak in "crosswords" has been fixed.
	* A bug in search.cgi in IspelMode db has been fixed.
	* Ispell data loading speed-up.
	* Some built-in database bugs have been fixed.
	  Thanks Darko Koruga <darkok@operamail.com>
	* Added search template variable $L - language limit selection.
	* A minor bug in navigator bar has been fixed.
	* Some memory leaks have been eliminated.
	* Stopwords are not checked now in the case of 
	  "substring match" searches.
	* A bug in Include indexer.conf command has been fixed.
	  Indexer didn't stop when included file had wrong syntax.
	* Various memory leaks fixed.
	* A minor bug in built-in database has been fixed.
	* A minor bug that URLs were not unescaped before parsing (when non-zero
	  URLWeight) has been fixed.

20 February 2001: 3.1.11

	* New feature so called "crosswords" has been added.
	  It allows to assign words between <a href="xxx"> and </a> 
	  also to a document this link leads to. It works in SQL database 
	  mode and is not supported in built-in database and "cache-mode". 
	  To enable crosswords, please use "CrossWord yes" command in 
	  indexer.conf and search.htm.
	* Phrase support in "cache mode" has been added. Use --enable-phrase
	  to activate it.
	* $ndocs template variable has been added. It displays the total
	  number of documents in the database.
	* A bug that absolute path where not work in $if() search.htm
	  include directive has been fixed.
	* Minor bug that fields category and tag were not filled in
	  "INSERT INTO url ..." queries has been fixed. Now tag and category
	  limits in "indexer -tXXX -gXXX" should work fine for not indexed 
	  yet documents.
	* Some locking in cache mode code has been added. Now threaded
	  version of indexer should work fine in cache mode.
	* A bugs in ServerTable have been fixed.
	* A bug in robots.txt locking in threaded version has been fixed.
	* Documentation updates

9 February 2001: 3.1.10

	* Phrase indexing has been implemented in SQL and built-in modes.
	  Note that cachemode does not support it yet. Now documents with
	  full phrases or their parts are displayed before others. Use 
	  "Phrase yes" in both search.htm and indexer.conf to activate this. 
	  It requires to rebuild MySQL and Oracle tables and does not require 
	  changes in SQL table structures for other databases. Index with 
	  phrases requires approximately four times more disk space than 
	  "Phrase no" version.
	* Indexer now stores number of each word appearance in "Phrase no"
	  version. Documents with greater word numbers will be displayed first.
	* You may select search for "full phrase" now among "all", "any" and
	  "boolean" search types.
	* MinWordLength and MaxWordLength commands have been added to
	  search template. Not matched words are considered as stopwords.
	* MinWordLength and MaxWordLength indexer.conf commands moved to
	  global section of indexer.conf. Now they have global effect for
	  whole indexer.conf. These fields also have been removed from 
	  ServerTable. 
	* Minor bug in file: URL scheme has been fixed. Indexer
	  didn't work properly with directories which contain space
	  character. Thanks "Kaspar Brand" <kasparb@freesurf.ch>.
	* A bug in incorrect "DeleteNoServer no" command behaviour
	  has been fixed.
	* A bug that URL limits didn't work in cachemode has been fixed
	* Documentation updates. New file doc/relevancy.txt has been added.
	* New --version-id udm_config parameter has been added


24 January 2001: 3.1.9

	* Substring search has been added. It works in "single" and "multi" 
	  modes in both SQL and built-in versions. As far as other modes use 
	  CRC32 for words storage they do not support substring search.
	* Allow, Disallow, CheckOnly, HrefOnly, Realm, AddType commands has 
	  been extended to support fast "string match" comparison instead of 
	  "regexp match". This improve indexer speed up to several times. Note 
	  that "string match" comparison type is default, this makes old 
	  indexer.conf files incompatible with 3.1.9 version. Check your 
	  indexer.conf and change it if required. Take a look into 
	  indexer.conf-dist for explanation.
	* Allow, Disallow, CheckOnly, HrefOnly now can take three optional
	  parameters and understand this syntax: 
	  "Allow match/nomatch case/nocase string/regex arg [arg...]".
	  AllowNoMatch, AllowCS, AllowCSNoMatch, DiallowNoMatch, DisallowCS,
	  DisallowCSNoMatch, HrefOnlyNoMatch, HrefOnlyCS, HrefOnlyCSNoMatch,
	  CheckOnlyNoMatch, CheckOnlyCS, CheckOnlyCSNoMatch indexer.conf
	  command have been removed.
	* New AliasProg indexer.conf command has been added. It allows
	  to process URL through an external aliasing command.
	* Server and Realm commands has been extended to support powerful
	  aliasing mechanisms. Take a look into doc/alias.txt
	* "StopwordTable table_name" indexer.conf and search.htm command
	  has been added."stopword" table isn't read automatically anymore.
	* "StopwordFile" indexer.conf and search.htm command has been added.
	  It loads stop-words from a text file instead of loading from SQL 
	  database. This command works in both built-in and SQL versions.
	* Ispell code has been extended to support prefixes.
	* IspellUsePrefixes indexer.conf and search template commands
	  has been added.
	* A bug in ispell code with incorrect regular expression check
	  has been fixed.
	* Affix table data format has been changed. All users who use 
	  "IspellMode db" have to reimport affix table.
	* indexer.conf variable 'IspellMode' has been added.
	  Now indexer can use 'IspellMode db' the same as search.cgi.
	* "lang" tag attribute support has been added. Tags like
	  <P lang="de">...</P> now take part in language guessing.
	* New "wf" search form variable has been added. It can be used
	  to change different document sections (body,title,keywords,
	  description) weights at search time or to choose sections to 
	  search through. Check search.htm-dist as an example and refer to
	  doc/search.txt for futher information.
	* indexer has been fixed to properly process some URLs. For example
	  those with special characters: 
		http://www.something.com/script.cgi?coord=12&amp;14  ->
		http://www.something.com/script.cgi?coord=12&14
	* "cache mode" now support quick search with tag, category and site
	  limits. "cache mode" storage format has been changed. It is now 
	  incompatible with previous version. Take a look into 
	  doc/cachemode.txt for more information.
	* "cache mode" log server "cachelogd" has been added. Now indexer makes 
	  TCP connect to cachelogd at startup. Cachlogd allows to run several
	  simultanious indexers even on different machines.
	* New "LogdAddr" indexer.conf command has been added.	
	* "HLBeg" and "HLEnd" search.htm variable has been added.
	  By using it you can specify how to highlight the words found.
	  HLBeg is prepended before the word. HlEnd is appended after 
	  the word. Defaults are "<b>" and "</b>" to comply with previous 
	  versions.
	* UseRemoteContentType indexer.conf variable has been added.
	  This command specifies if the indexer should get content type
	  from http server headers (yes) or from it's AddType settings (no).
	  If set to 'no' and the indexer could not determine content-type
	  by using its AddType settings, then it will use http header.
	  Default is yes.
	* Turkish iso-8859-9 and windows-1254 character sets support
	  has been added. Thanks Oyku Gencay <oyku.gencay@veezy.com>.
	* Modified version of connect() with timeout has been added to
	  be more sensitive with network problems.
	* New "DocTimeout" indexer.conf command has been added. It limits
	  total amount of time for each document fetching.
	* Title, keywords and description inside <!--UdmComment--> 
	  are not indexed anymore.
	* Major memory leak in InterBase driver has been fixed.
	  Thanks mordicus <mordicus@free.fr>.
	* A bug that some SQL error messages were not displayed in search.cgi
	  has been fixed.
	* A bug that paths from robots.txt where not escaped before
	  adding into database has been fixed.
	* ftp code improvements and minor bug fixes.
	* Fixed that boolean search did not work in built-in database.
	* Some code clean-ups which fixes compilation warnings.
	* Call for possibly broken strptime() removed from search_tl.c
	* A bug that DBPort command didn't not work with MySQL has been fixed.
	  MySQL driver has been changed to use mysql_real_connect() instead
	  of mysql_connect().
	* New -g command line argument has been added to indexer. Now one
	  is able to tell indexer which category to index.
	* External parsers code has been rewritten. It now supports four
	  parser types: STDIN->parser->STDOUT, FILE->parser->STDOUT,
	  STDIN->parser->FILE, FILE->parser->FILE. indexer now creates UDM_URL 
	  environment variable with a URL being processed as a value when 
	  executing external parser. Several bugs have been fixed and  
	  more features have been added. Take a look in doc/parsers.txt for 
	  more information.
	* New exec:  and cgi:  virtual schemes. cgi: allows to index CGI
	  scripts wihtout having to involve HTTP server in indexing process.
	  exec: scheme allows to use external retrival programs to index
	  protocols which are not natively supported by mnoGoSearch, 
	  for example HTTPS.
	* Documentation updates.

	* Case sensitive Allow/Disallow/CheckOnly/HrefOnly commands have 
	been added.
	* New "Realm <regex>" indexer.conf command has been added.
	It works like "Server" but takes a regular expression as it's
	parameter. Servers are not sorted by URL length after loading
	anymore. They are found in the order of appearence in indexer.conf.
	It means that if you want different parameters for server
	subsections, use "Server" command for subsection first, then
	command "Server" for whole server.
	* Default indexer.conf has been reorganized. All commands now
	devided into five logical sections.
	* Crash in UdmFreeParsers() has been fixed.
	* A bug in page navigator has been fixed. Bug since 3.1.7.
	* A bug in new Period format has been fixed.

	link given in "Location" HTTP header even if "Follow page" or 
	"Follow no" is specified for current "Server".

16 October 2000: 3.1.7

	* indexer.conf parameters Period, MirrorPeriod, NetErrorDelayTime,
	ReadTimeout now can be specified in more convenient way.
	* New different "Follow" indexer.conf command values have been
	added for more flexible spidering configuration.
	* New "follow_type" optional "Server" indexer.conf command argument
	has been added to specify site realm.

	affixes and dictionaries. For example, if you are searching for

	testing, testings, tests will be found as well. Multiple languages
	are supported. This was tested for English and Russian, but it
	should be extremely easy for other languages too. Ispell is

	query language.

	search to show document clones, well, documents with the same contents
	but different locations. It is also used by indexer itself to decide
	whether to parse document again or not, which further improves indexing
	speed. If you are upgrading from previous verion, please use
	'indexer -a -m' to reindex proper all documents. Option -m prevent
	indexer from sending 'If-Modified-Since' HTTP header.
	* Various improvements and bugfixes.
