*History of the TWiki Implementation (version %WIKIVERSION%)*

	* PeterThoeny - 23 Jul 1998: Installed initial version, based on the JOS Wiki. See WikiWikiClones for details.
	* PeterThoeny - 27 Jul 1998: Added automatic links to topics in other TWiki webs by specifying &lt;web name&gt;.&lt;topic name&gt;, e.g. =Know.WebSeach= .
	* PeterThoeny - 28 Jul 1998: Topic WebSearch allows full text search and and topic search with/without regular expressions.
	* PeterThoeny - 28 Jul 1998: Topic index. (Technically speaking a simple '.*' search on topic names.) 
	* PeterThoeny - 28 Jul 1998: Topic WebChanges shows Wiki username instead of Intranet username, e.g. =PeterThoeny= instead of =thoeny= in case the Wiki username exists. Implementation: Automatic lookup of Wiki username in topic Main.TWikiUsers.
	* PeterThoeny - 28 Jul 1998: Added TWiki variables, enclosed in % signs: =%<nop>TOPIC%= (Topic name), =%<nop>WEB%= (web name), =%<nop>SCRIPTURL%= (script URL), =%<nop>DATE%= (current date), =%<nop>WIKIWEBMASTER%= (Wiki webmaster address), =%<nop>WIKIVERSION%= (Wiki version), =%<nop>USERNAME%= (user name), =%<nop>WIKIUSERNAME%= (Wiki user name).
	* PeterThoeny - 31 Jul 1998: Support for quoted text with a '>' at the beginning of the line.
	* PeterThoeny - 04 Aug 1998: Warn user if new topic name is not a valid Wiki name. (template file templates/Web/notwiki.tmpl)
	* PeterThoeny - 04 Aug 1998: Separate templates for text of non existing topic and default text of new topic. (template file templates/Web/notedited.tmpl)
	* PeterThoeny - 05 Aug 1998: Signature and date is inserted automatically when creating a new topic.
	* PeterThoeny - 06 Aug 1998: Added server side include of files. Syntax is =%INCLUDE:<nop>"filename.ext"%=
	* PeterThoeny - 07 Aug 1998: Automatic email notification when something has changed in a TWiki web. Each web has a topic WebNotify where one can subscribe and unsubscribe.
	* PeterThoeny - 13 Aug 1998: WikiNotation allows also numbers after the <code>AaA</code> sequence, e.g. <code>AaA1</code> is a valid WikiTopic name, but not <code>Aa1</code>.
	* PeterThoeny - 24 Sep 1998: Corrected templates for automatic email notification so that MS Outlook can display attachment as an HTML file.
	* PeterThoeny - 13 Oct 1998: Alphabetical topic index in WebSearch.
	* PeterThoeny - 14 Oct 1998: Refered-By: Find out which topics have a link to the current topic. Each topic has a |Ref-By| link for that. Note: Only references from the current web are shown, not references from other webs.
	* PeterThoeny - 26 Oct 1998: Added revision control using RCS. Each topic has now a list of revisions at the bottom and a revision info, e.g. <br> <code> Topic <nop>TWikiHistory . { Edit | Ref-By | r1.3 | r1.2 | r1.1 } <br> Revision r1.3: 1998/10/26 01:34:00 by PeterThoeny </code>
	* PeterThoeny - 26 Oct 1998: Added preview of topic changes before saving the topic. This was necessary to prevent unneeded revisions.
	* PeterThoeny - 10 Nov 1998: View differences between topic revisions. Each topic has a list of revisions (e.g. <code>r1.3</code>) and differences thereof (e.g. <code>&gt;</code>) at the bottom: <br> <code> Topic <nop>TWikiHistory . { Edit | Ref-By | r1.3 | > | r1.2 | > | r1.1 } <br> Revision r1.3: 1998/11/10 01:34 by PeterThoeny </code>
	* PeterThoeny - 10 Nov 1998: The email notification and the Changes topic have now a topic date that is linked. Clicking on the link will show the difference between the two most recent topic revisions.
	* PeterThoeny - 18 Nov 1998: Internal log of topic save actions to the file <code>data/logYYYYMM.txt</code>, where <code>YYYYMM</code> the year and month in numeric format is. Intended for auditing only, not accessible from the web.
	* PeterThoeny - 07 Dec 1998: Possible to add a category table to a TWiki topic. This permits storing and searching for more structured information. Editing a topic shows a HTML form with the usual text area and a table with selectors, checkboxes, radio buttons and text fields. TWikiDocumentation has more on setup. The TWiki.Know web uses this category table to set classification, platform and OS version. 
	* PeterThoeny - 08 Dec 1998: Signature is shown below the text area when editing a topic. Use this to easily copy & paste your signature into the text.
	* PeterThoeny - 04 Jan 1999: Fixed bug when viewing differences between topic revisions that include HTML table tags like &lt;table&gt;, &lt;tr&gt;, &lt;td&gt;.
	* PeterThoeny - 03 Feb 1999: Possible to view complete revision history of a topic on one page. Access at the linked date in the Changes page, or the <code>Diffs</code> link at the bottom of each topic, e.g. <br> <code> Topic <nop>TWikiHistory . { Edit | Ref-By | Diffs | r1.3 | > | r1.2 | > | r1.1 } <br> Revision r1.3: 1998/11/10 01:34 by <nop>PeterThoeny </code>
	* PeterThoeny - 09 Feb 1999: No new topic revision is created if the _same_ person saves a topic again within _one_ hour.
	* PeterThoeny - 09 Feb 1999: New text formatting rule for creating =fixed font text= . Words get showns in =fixed font= by enclosing them in "=" equal signs. Example: Writing <nop>=fixed font=<nop> will show up as =fixed font= .
	* PeterThoeny - 26 Mar 1999: New variables =%<nop>PUBURL%= (Public directory URL) and =%<nop>ATTACHURL%= (URL of topic file attachment).
	* PeterThoeny - 26 Mar 1999: File attachments: Upload and download any file as a topic attachment by using the browser. FileAttachment has more.
	* PeterThoeny - 15 Apr 1999: Topic locking: Warn user if a topic has been edited by an _other_ person within _one_ hour. This is to prevent contention, e.g. simultaneous topic updates.
	* PeterThoeny - 20 May 1999: New variables =%<nop>WIKIHOMEURL%= (link when pressing the icon on the upper left corner) and =%<nop>WIKITOOLNAME%= (the name of the wiki tool: =%WIKITOOLNAME%= ).
	* PeterThoeny - 20 May 1999: Added meta tag so that robots index only /view/ of topics, not /edit/, /attach/ e.t.c. Tag: &lt;META NAME="ROBOTS" CONTENT="NOINDEX"&gt;
	* DavidWarman - 21 May 1999: Externalize copyright text at the bottom of every page into a web-specific =webcopyright.inc= file. This is to easily customize the copyright text. 
	* PeterThoeny - 23 Jun 1999: Separate wiki.pm into configuration (wikicfg.pm) and TWiki core (wiki.pm) . This is to ease the upgrade of TWiki installations, it also allows customized extensions to TWiki without affecting the TWiki core.
	* PeterThoeny - 23 Jun 1999: New TextFormattingRules to write __bold italic__ text by enclosing words with double underline characters.
	* ChristopheVermeulen - 07 Jul 1999: Link a plural topic to a singular topic in case the plural topic does not exist. Example: =TestVersion= / =TestVersions= , =TestPolicy= / =TestPolicies= , =TestAddress= / =TestAddresses= , =TestBox= / =TestBoxes= .
	* PeterThoeny - 15 Jul 1999: Search path for include files in =%<nop>INCLUDE:"file.inc"%= variable. Search first in the current web, then in parent data directory. Useful to overload default include text in the data directory by web-specific text, like for example =webcopyright.inc= text.
	* PeterThoeny - 21 Jul 1999: Flag =$doRemovePortNumber= in wikicfg.pm to optionally remove the port number from the TWiki URL. Example: =www.some.domain:1234/twiki= gets =www.some.domain/twiki= .
	* PeterThoeny - 22 Jul 1999: Flags =$doLogTopic*= in wikicfg.pm to selectively log topic view, edit, save, rdiff, attach, search and changes to monthly log file.
	* PeterThoeny - 03 Aug 1999: Online registration of new user using web form in TWikiRegistration. Authentication of users.
	* PeterThoeny - 08 Aug 1999: New text formatting rule for creating tables. Text gets rendered as a table if enclosed in "|" vertical bars. Example line as it is written and how it shows up: <br>
	  =| This | is | a table | with | cells |=
	  | This | is | a table | with | cells |
	* PeterThoeny - 31 Aug 1999: Fixed Y2K bug. (Date in year 2000 had wrong format.)
	* PeterThoeny - 03 Oct 1999: Limit the number of revisions shown at the bottom of the topic. Example: <br> Topic <nop>%TOPIC% . { ..... | <A href="../../rdiff/%WEB%/%TOPIC%">Diffs</A> | r1.10 | <A href="../../rdiff/%WEB%/%TOPIC%?rev1=1.10&rev2=1.9">&gt;</A> | <A href="../../view/%WEB%/%TOPIC%?rev=1.9">r1.9</A> | <A href="../../rdiff/%WEB%/%TOPIC%?rev1=1.9&rev2=1.8">&gt;</A> | <A href="../../view/%WEB%/%TOPIC%?rev=1.8">r1.8</A> | <A href="../../rdiff/%WEB%/%TOPIC%?rev1=1.8&rev2=1.7">&gt;</A> | <A href="../../view/%WEB%/%TOPIC%?rev=1.7">r1.7</A> | <A href="../../oops/%WEB%/%TOPIC%?template=oopsrev&param1=1.10">&gt;...</A> } <br> Additional revisions can be selected by pressing the =>...= link. 
	* PeterThoeny - 10 Jan 2000: No more escaping for '%' percent characters. (Number of consecutive '%' entered and displayed is identical.)
	* PeterThoeny - 24 Jan 2000: Fixed bug where an email address starting with a WikiName was rendered as an internal Wiki link instead of an email address, i.e. SomeWikiName@somewhere.test .
	* PeterThoeny - 29 Jan 2000: Fixed bug where TWiki would not initialize correctly under certain circumstances, i.e. when running it under mod_perl. Sub =initialize= in =wiki.pm= did not handle =$thePathInfo= correctly.
	* PeterThoeny - 04 Feb 2000: Access statistics. Each web has a WebStatistics topic that shows monthy statistics with number of topic views and changes, most popular topics, and top contributors. (It needs to be enabled, TWikiDocumentation has more.)
	* PeterThoeny - 07 Feb 2000: Inline search. New variable =%<nop>SEARCH{"str" ...}%= to show a search result embedded in a topic text. TWikiVariables has more on the syntax. Inline search combined with the category table feature can be used for example to create a simple bug tracking system.
	* PeterThoeny - 07 Feb 2000: Changed the syntax for server side include variable from =%<nop>INCLUDE:"filename.ext"%= to =%<nop>INCLUDE{"filename.ext"}%= . (Previous syntax still supported. Change was done because of inline search syntax)
	* PeterThoeny - 11 Feb 2000: New variable =%<nop>SCRIPTURLPATH%= / $scriptUrlPath containing the script URL without the domain name. Templates have been changed to use this variable instead of =%<nop>SCRIPTURL%= . This is for performance reasons.
	* PeterThoeny - 11 Feb 2000: New variable =%<nop>SCRIPTSUFFIX%= / $scriptSuffix containing an optional file extension of the TWiki Perl script. Templates have been changed to use this variable. This allows you to rename the Perl script files to have a file extension like for example ".cgi".
	* PeterThoeny - 25 Feb 2000: Edit preferences topics to set TWiki variables. There are three level of preferences: Site-level (TWikiPreferences), web-level (WebPreferences in each web) and user-level preferences (for each of the Main.TWikiUsers). With this, discontinue use of server side include of =wikiwebs.inc= , =wikiwebtable.inc= , =weblist.inc= , =webcopyright.inc= and =webcolors.inc= files. 
	* PeterThoeny - 25 Feb 2000: New preference variables =%<nop>EDITBOXWIDTH%= and =%<nop>EDITBOXHEIGHT%= to specify the edit box size.
	* PeterThoeny - 11 Mar 2000: Better security with taint checking ( =Perl -T= option )
	* PeterThoeny - 20 Mar 2000: Uploading a file (topic file attachment) will optionally create a link to the uploaded file at the end of the topic. The preference variable =%<nop>ATTACHLINKBOX%= controls the default state of the __link__ check box in the attach file page.
	* JohnAltstadt, PeterThoeny - 21 Apr 2000: TWikiRegistration is done separately for Intranet use (depends on remote_user) or Internet use (depends on .htpasswd file).
	* PeterThoeny - 21 Apr 2000: New TWikiVariables =%<nop>HTTP_HOST%= , =%<nop>REMOTE_ADDR%= , =%<nop>REMOTE_PORT%= and =%<nop>REMOTE_USER%= .
	* KevinKinnell, PeterThoeny - 02 May 2000: Advanced search features like search multiple webs; sort by topic name / modified time / author; limit the number of results returned. More in TWikiVariables.
	* PeterFokkinga - 15 May 2000: Each topic can have its own template file. TWikiTemplates has more.
	* PeterThoeny - 28 May 2000: Lock warning shows remaining lock time in minutes.
	* PeterThoeny - 29 May 2000: New =%<nop>GMTIME%= variable that shows the current GM time.
	* CrisBailiff, PeterThoeny - 21 Jun 2000: Fixed security issue to prevent a server side =%<nop>INCLUDE%= of arbitrary files.
	* PeterThoeny - 21 Jun 2000: Fixed problem that a page redirect on some server environments is not working (host name is needed in URL).
	* PeterThoeny - 07 Jul 2000: Fixed problem of losing carriage returns when editing topics with KDE KFM browser or W3M browser.
	* PeterThoeny - 07 Jul 2000: Added an "Release edit lock" checkbox in preview to let other people edit the topic immediately without the one hour lock.
	* PeterThoeny - 22 Jul 2000: Split the TWiki.Main web into TWiki.Main (users, company data) and TWiki.TWiki (TWiki related documentation, registration)
	* PeterThoeny - 22 Jul 2000: More forgiving syntax for =*bold*, _italic_, __bold italic__= and ==fixed== , where it is not necessary anymore to have a trailing space before =.,;:?!= characters.
	* PeterThoeny - 23 Jul 2000: BookView search allows you show a set of topics for easy printing.
	* PeterThoeny - 23 Jul 2000: Changed include syntax from =%<nop>INCLUDE{"Web/TopicName.txt"}%= to =%<nop>INCLUDE{"Web.TopicName"}%= . Legacy syntax still supported.
	* PeterThoeny - 29 Jul 2000: New variables =%<nop>GMTIME{"..."}%= and =%<nop>SERVERTIME{"..."}%= . More in TWikiVariables.
	* PeterThoeny - 16 Aug 2000: New TWikiPreferences variables =%<nop>HTTP_EQUIV_ON_VIEW%= , =%<nop>HTTP_EQUIV_ON_EDIT%= and =%<nop>HTTP_EQUIV_ON_PREVIEW%= that define the =&lt;meta http-equiv="..."&gt;= meta tags for the TWiki templates. This can be used for example to set a document expiration time.
