-------
17 February 2005: 3.2.31

	* Misspelled search word suggestion were added. If
	  a search query didn't return any results,
	  a "Did you mean: similar query" link is displayed.
	  To start using this feature, one needs to run
	  "indexer -Ewordstat" once after indexing, as well as
	  add "Suggest yes" into search.htm. Suggestions currently
	  work only for those languages using Latin script.
	* Fixed that indexer crashed when "Section CachedCopy"
	  was configured in a mistake as a user defined section,
	  i.e. with "expression" and "replacement" arguments (bug#749).
	* Fixed that "Section body" was hardcoded and didn't work
	  as a user defined section (bug#751).
	* Fixed that indexer compiled with --enable-trace
	  crashed if /tmp/udm_agent.0.trace is not writtable.
        * Converter to DBMode=blob was improved to use less memory.
        * Queries returning big number of rows are now a bit faster with MySQL.
        * Ispell dictionaries are loaded a bit faster.
        * Several minor stability improvements were made.
	  
21 January 2005: 3.2.30
	* HTMLENCODE function was added into template language.
	* Fixed that indexer crashed when trying to execute an
	  external parser if /tmp is not writtable.
	* Fixed that cached copy was created for CheckOnly and
	  CheckMP3Only documents (bug#628)
	* Fixed that indexer crashed if MirrorPeriod was set
	  without MirrorRoot (bug#642).
	* Fixed that indexer with -nX, e.g. "indexer -n10" 
	  marked more than X documents as non-expired, making
	  them temporarily not available for indexing during
          subsequent indexer start.
        * Fixed that mnogosearch didn't process URLs containing
          slashes in query string correctly, in particular it resulted in
          that socket=/tmp/mysql.sock part was ignored in DBAddr.
        * Fixed that search.cgi crashed in certain cases.
        * Minor bugs #625, #729 were fixed.
        * Bugs in phrase search with stopwords (#546, #645) were fixed.
        * A new WordCacheSize indexer.conf command was added. Increasing
          it allows to improve indexing speed in dbmode=multi.
        * searchd has been removed from the distribution.
	  
24 December 2004: 3.2.29
        * A subtle bug which led to search.cgi crashes in rare cases was fixed.
        * PHP-4.3.x backward compatibility changes were made. These changes fix
	  mnoGoSearch PHP module compilation failure introduced in 3.2.25.
        * Search speed improvements in blob mode were made. search.cgi
	  now loads url data in a smarter way.
        * search.cgi now accepts only double quotes as phrase delimiters.
	  Apostroph signs don't work as phrase delimiters anymore. This
	  change fixes problems with French and English languages, where
	  apostrophes are commonly used as word parts (e.g. dog's or isn't). 
        * Several fixes in boolean and phrase search were made.
        * A bug with accented characters in URL was fixed.
	* Bug#718 "Incorrect parsing of XHTML isolated tags in templates"
	  was fixed.
        * Cosmetic bug #722 was fixed.
	
17 December 2004: 3.2.28
        * Fixed that PagesPerScreen search.htm command didn't work in 3.2.27.
        * A bug in PopRank calculation was fixed.
        * A bug in phrase and boolean search was fixed (Bug#651).
	  It showed up when the same word appeared more than
	  once in the same query, e.g. a boolean search "(~a & b) | (a & ~b)"
	  or a phrase search "as well as".
        * A bug with indexer crash when fetching a long "file:" url was fixed.
        * Cosmetic bugs #705, #706, #712 were fixed.

10 December 2004: 3.2.27
	* A cross scripting vulnerability problem was fixed. It could
	  be used to obfuscate/fake the output and/or steal cookies
	  by inserting arbitrary html/javascript code when navigating
	  through next/prev search results page as well as extended/simple
	  search form links. The Common Vulnerabilities and Exposures
	  project (cve.mitre.org) has assigned the name CAN-2004-1059
	  to this issue. Thanks to Michael Krax and Mark J Cox for
	  reporting the problem and for advising how to fix it.
	* Default template search.htm-dist improvements were made.
	  Thanks to Igor Pashev for the suggestions (Feature request#687).
        * ODBC driver improvements were made.
	* Fixed that htdb:/ doesn't make indexer crash anymore
	  without HTDBAddr specified. It now reuses DBAddr connection
	  to access the source data.
        * Fixed that Include command didn't work in search.htm (Bug#637).
        * Fixed that DateFormat didn't affect clone dates (Bug#696).
	  
03 December 2004: 3.2.26
	* Search speed improvements were made. This change mostly
	  affects blob mode users. It makes searches bringing dozen
	  thousand results up to eight times faster in some cases.
	* <!--noindex-->...<!--/noindex--> syntax was added
	  as a synonym for <noindex>...</noindex>.
	* It is now possible to use %XX syntax to escape 
	  special characters like ':', '<', '>', '?', '#', '@'
	  in user and password part of DBAddr command, for example,
	  DBAddr mysql://root:%3A%3B%3C%3D%3E%3F%40@localhost/test/
	* It's now possible to switch MySQL query logging on/off
	  using sqllog parameter in DBAddr, e.g.
	  DBAddr mysql://user:pass@host/db/?sqllog=0
        * Fixed that Allow/Disallow filters were applied to alias
	  rather than the original URL.
        * Fixed that Oracle didn't work via EasySoft ODBC driver.
        * A bug in robots.txt processing was fixed (Bug#686).
	
22 November 2004: 3.2.25
	* DetectClone/NoDetectClone optional flag was
	  added into Section indexer.conf command. It specifies
	  whether a section should be taken in account for
	  clone detection.
	* URLDECODE function was added into template language.
	* search.cgi now loads ispell files several times faster.
	  Those who use searchd for faster ispell support can
	  reconfigure not to use searchd anymore.
	* LoadChineseList/LoadThaiList now use file names
	  relative to /etc directory of mnoGoSearch installation.
	* Better error reporting on LoadChineseList/LoadThaiList
	  failures.
	* Database merge mode, i.e. search with several DBAddr,
	  was fixed.
	* Fixed that documents with <META NAME="Robots" CONTENT="NOINDEX">
	  were processed incorrectly in some cases.
	
4 November 2004: 3.2.24
        * Indexing speed improvements in "multi" DBMode.
        * Search results limit by a user defined section.
        * Search result ordering by a user defined section.
	* Case sensitive conditional template operator was added: 
	  <!IFCS NAME="a" CONTENT="ABC">ABC<!ENDIF>
	* Fixed that PHP --with-mnogosearch didn't compile
	  if mnoGoSearch was build with --enable-pthreads.
	* Windows character set canonical names were renamed
	  to conform IANA registry, e.g. cp1251 -> windows-1251.
	  (see http://www.iana.org/assignments/character-sets)
	  mnoGoSearch uses canonical names when displaying
	  HTTP headers and META-tags. Some browsers didn't
	  understand cp1251-style notation.
	 
20 October 2004: 3.2.23
	* New template operators: WHILE, WHILENOT, INC, DEC.
        * Blob-mode converter was improved.

        * Bug with empty dictFF was fixed.
        * Bug #513 was fixed.

14 October 2004: 3.2.22
	* New template section was added:
	<!--variables--> ... <!--/variables-->. Unlike all other
	sections, it is executed *before* starting search process.
	Thus you can set some variables additionally to those passed
	in QUERY_STRING, e.g:
	
	  <!--variables-->
	  <!SET NAME="ul" CONTENT="/subdir/">
	  <!--/variables-->
        * User defined sections were added. It is now possible
	  to assign a section to a document part by specifying
	  its context using a regular expression, for example:
	  
	    Section mytitle 10 100 "<h1>(.*)</h1>" $1
	  
	  Text between "<h1>" and "</h1>" will be handled as 
	  a separate section.
	* A possibility to use a non-standard socket with PgSQL was added.
        * Indexing speed improvements with UseCRC32URLId were done.
        * multi mode improvements were done.
        * A bug in MySQL create scripts for multi mode was fixed.
        * AliasProg bug was fixed.
        * UdmMarkForReindex bug was fixed.
        * Buffer overflow in UdmMatch was fixed.
        * Bugs #599, #622, #624, #627, #631, #647 were fixed.

	* Compilation failure on some platforms was fixed.
	
23 August 2004: 3.2.20
	* One now can run indexer.conf by making it executable
	  and adding "#!/usr/local/mnogosearch/sbin/indexer -d" line
	  in the beginning. This change simplifies maintaining
	  several search databases on the same machine.
	* "Include inc.conf" command now tries to open a file relative
	  to the current indexer.conf before opening a file relative
	  to /usr/local/mnogosearch/etc/. This change provides yet
	  more flexibility to maintain several databases.
	  Thanks to Carsten Bleek and Axel Schwenke.
	* Italian synonym file was added. Thanks to Marcello.
	* Several ul arguments for multiple selects are
	  accepted by search.cgi again.

          #638, #639, #640, #643, #644, #649, #650, #652 were fixed.
	
07 July 2004: 3.2.19
	* HTDB path part substitution now unescapes path parts when
	  building a HTDBList/HTDBDoc query. E.g. if one uses
	  "SELECT id FROM tab WHERE category='$1'" as a HTDBList
	  query together with "Server htdb:/red%20cars/", the
	  unescaped value "red cars" will be substituted instead
	  of $1. This change makes it possible to use spaces and
	  punctuation characters in htdb:/ URLs.
	* 1K limit in the maximum possible HTDBDoc and HTDBList
	  query length was fixed.
	* Loading URL data was optimized in blob-mode.
	* Bugs #518, #555, #578, #590, #610, #612 were fixed.

	* Fixed that stored_href search.htm variable is not set unless
	  CachedCopy really presents. Bug since 3.2.17.
	* Several searchd related fixes.
	* 4 Kilobyte CachedCopy limit with Oracle was fixed. 
	* New fast blob-mode is available for testing.
	  Note: you should index your data with "multi" mode and
	  then run "indexer -Eblob" to convert "multi" tables into "blob".
	  Use "dbmode=blob" in search.htm DBAddr command.
	  This mode work only with MySQL for now, but will be
	  extended to work with other databases in the future.

	  ftp:// and file:// URL schemes.
	* IndexIf indexer.conf command was added. You can now build
	  a sophisticated set of rules describing which documents
	  should or should not be indexed. For example, you 
	  can index documents only in German language, or only
	  documents not containing some words in their body or title.
	* Cached copies are now stored in SQL database,
	  There is no "stored" program anymore. It is much easier

	  "Server HrefOnly http://localhost/" forces indexer to
	  download given documents, to get new links from them
	  without but indexing of documents content.
	* "Follow" command was removed. Use "Server" or "Realm" instead.
	* text/xml indexing was added, needs Expat library to be installed.
	  Use --with-expat configure switch to activate.

	  transfer encoding, the original (uncompressed) size is stored now 
	  into url.docsize.
	* search.cgi now doesn't fetch whole document from "stored" to display
	  the search words excerptions. Fetching stops when enough excerptions
	  have been already built.

	* "ServerTable" indexer.conf command syntax was changed. Use this
	  style syntax: "ServerTable mysql://user:pass@host/dbname/tablename"
	  to load servers information from "tablename" SQL table. Note that
	  now you can load servers information using a database different
	  from the specified one in "DBAddr" command.
	* "DBAddr" argument format for Interbase was changed. Use 
	  "DBAddr ibase://hostname/path/to/mnogosearch.gdb/" with trailing 
	  slash after the *.gdb file name.
	* A trap on too long and escaped URLs was fixed.
	* Some memory leaks were fixed.

	* <!--stored--> section is now processed like <!--clone--> section.
	* "stored" now supports "delete" and "optimize" operations. 
	* search.cgi used with "stored" can now return excerpts from document
	  around a place where search word is found.

	  size. Use --with-extra-charsets to activate compilation of
	  these charsets.
	* Added NL, TL, BG, SV, DA, FR, ES, DE, HR languages 
	  maps built on Bible.
	* Added Esperanto language maps. Thanks to Arto Sarle <arto@sarle.com>
	* Now one can load several files for the same lang + charset 
	  combination. It improves guesser results quality.
	* Some other improvements in language and charset guesser.
	* Removed command DeleteNoServer. Use "Follow world" instead.
	* Removed "SearchdAddr hostname:port" template command.
	  Use "DBAddr searchd://hostame:port/" instead.

	* Added 'src','width','height','size' and 'class' attributes 
	  processing in templates
	* Added wordinfo and searchwords highlighting when searchd used.
	  ATN: you need clear search cache, because format was changed.

	  document presents in stored and fill this section only on success.
	* Added new formatting in template variables. Now it's possible 
	  to limit variable displayed length. Use $(DU:40) to limit URLs to 
	  40 characters. This helps for example to avoid breaking tables 
	  structure in search results when URL is long enough.
	* Added new fields in query tracking system. Now it stores user's IP 
	  address. Don't forget to ALTER qtrack table according to new 
	  structure.

	  <twp@unchi.org>.
	* Fixed compilation problems with ODBC libraries.Bug since 3.2.0.
	* Fixed EasySoft ODBC libraries linking problem which appeared because 
	  EasySoft changed names of their libraries. Now configure substitutes

	* Added some signal safeness in searchd.
	* Fixed that searchd.conf-dist were not included into
	  distribution.
	* Fixed that national letters in the code range.

	  indexer to stall or crash in some cases.
	* Fixed that "Proxy" command was ignored.

24 Sept 2001: 3.2.0
	* Now one can compile with several SQL databases support at
	  the same time.
	* Now one can make a binary distribution using "make bin-dist".
	* Added new program searchd. Among other features, it allows 
	  to build a search cluster, distributing between several machines.
	* Support for synonyms fuzzy search has been added.
	* Common words endings fuzzy search using ispell now works in 
	  3.2 branch.
	* New "ReverseAlias" indexer.conf command. This command has
	  the same format with "Alias" command. However, URL mapping
	  is executed just after the moment when new link has been found.
	  URL is stored into database after ReverseAliases applying.
	  Among other things it allows for example to index PHP driven 
	  sites which add an unique session ID in the form 
	  "PHPSESSION=344646342345df". ReverseAlias is able to remove such
	  substrings from URLs.
	* New "Subnet xxx.xxx.xxx.xxx" indexer.conf command. It works
	  like Realm but checks an IP address matching instead of URL. 
	  For example, "Subnet 195.239.38.*" or "Subnet NoMatch 192.*.*.*".
	* Search results highlighting (HlBeg and HlEnd search.htm commands)
	  now works in 3.2 branch.
	* CT-Lib support has been added. Now one can
	  use mnoGoSearch together with SyBase and MS SQL
	  natively, without ODCB drivers. Both original SyBase
	  CT-Lib and FreeTDS CT-Lib are supported. However Ct-Lib 
	  driver is still in beta.
	* indexer now works approximately twice faster with Interbase.
	* Added deflate and compress Content-Encoding support.
	* New VarDir command in search.htm. It works like the same
	  indexer.conf command but at search time.

	  old ***Weight commands, which have been removed. Take a look into
	  indexer.conf-dist and search.txt for an explanation.
	* Now it is possible to index user-defined META tags as well as
	  HTTP response headers.
	* New "Alias" command in search.htm. It works like "Alias"
	  in indexer.conf but at a search time.
	* Added support for external includes in search template.
	  Format differs from 3.1.x version. Take a look into
	  "templates.txt" for usage information.
	* "Alias" command has been extended. Now it can optionaly use 
	  powerful URL mapping using regular expressions like in "Realm"
	  command.
	* Posix threads now should work not only Linux and FreeBSD.
	  Detection for threads for a number of platforms has been added.
	* libudmsearch compilation with pthreads fix. It fixes 
	  Apaches with PHP mnoGoSearch extension module crashes
	  when mnoGoSearch was compiled with pthreads support.
	* Tag parser has been rewritten. It now properly process
	  tag attributes with '>' signs, like for example 
	  <META NAME=email Contents="<general@mnogosearch.org>">.
	  Earlier '>' signs inside quotes was considered as a tag
	  endings.
	* Apple Darwin fixes for configure scripts
	* Extended number of query parameters stored in qtrack table
	* Added url.charset field. Charset is now stored separately from
	  content_type field. Please recreate or ALTER "url" table structure.

	* Content encoding support added (currently gzip only).
	  Requires libz to compile. Use --with-zlib to activate.
	* Fixed that $(DE) was not working
	* Fixed that the correct charset was forgotten after 
	  robots.txt processing.
	* Fixed several bugs in new "cache mode".


03 Jul 2001: 3.2.0.b1
	* Charsets processing has been rewritten. Now mnoGoSearch supports 
	  almost all widely used charsets: various single-byte charsets as 
	  well as multi-byte charsets including UTF-8, Chinese (BIG5, GB2312), 
	  Korean (EUC-KR), Japanese (S-JIS). All internal processing works
	  using UNICODE representation. Using UTF8 as a LocalCharset one can 
	  build a multi-lingual search engine with languages which could not 
	  be indexed at the same time in 3.1.x branch, for example 
	  German+Greek+Russian+Chinese.
	* Character sets module has a new automatic language and charset 
	  detection. Currently more than 70 various charsets and languages
	  can be detected automatically when they are not specified in
	  "Content-type" and "Content-Language" server's response headers or 
	  html META tags.
	* News extensions now compiled without --enable-news-extensions.
	  Use "NewsExtensions yes" indexer.conf command to activate them.
	* search.cgi has been rewritten.
	* Cache-mode has been rewritten.
