**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 <web name>.<topic name>, 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: <code>%TOPIC%</code> (Topic name), <code>%WEB%</code> (web name), <code>%SCRIPTURL%</code> (script URL), <code>%DATE%</code> (current date), <code>%WIKIWEBMASTER%</code> (Wiki webmaster address), <code>%WIKIVERSION%</code> (Wiki version), <code>%USERNAME%</code> (user name), <code>%WIKIUSERNAME%</code> (Wiki user name).
* [[PeterThoeny]] - 31 Jul 1998: Support for quoted text with a '&gt;' 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 <code>%INCLUDE:"filename.ext"%</code>
* [[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 `AaA` sequence, e.g. `AaA1` is a valid [[WikiTopic]] name, but not `Aa1`.
* [[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 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. `r1.3`) and differences thereof (e.g. `>`) at the bottom: <br /><code> Topic TWikiHistory . \{ Edit | Ref-By | r1.3 | &gt; | r1.2 | &gt; | 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 `data/logYYYYMM.txt`, where `YYYYMM` 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 &amp; 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 `Diffs` link at the bottom of each topic, e.g. <br /><code> Topic TWikiHistory . \{ Edit | Ref-By | Diffs | r1.3 | &gt; | r1.2 | &gt; | r1.1 \} <br /> Revision r1.3: 1998/11/10 01:34 by 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 =fixed font= will show up as `fixed font` .
* [[PeterThoeny]] - 26 Mar 1999: New variables <code>%PUBURL%</code> (Public directory URL) and <code>%ATTACHURL%</code> (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 <code>%WIKIHOMEURL%</code> (link when pressing the icon on the upper left corner) and <code>%WIKITOOLNAME%</code> (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 <code>%INCLUDE:"file.inc"%</code> 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 |`<table border="1" cellpadding="1" cellspacing="0">
  <tr>
    <td> This </td>
    <td> is </td>
    <td> a table </td>
    <td> with </td>
    <td> cells </td>
  </tr>
</table>
* [[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 %TOPIC% . \{ ..... | [Diffs](../../rdiff/%WEB%/%TOPIC%) | r1.10 | [&gt;](../../rdiff/%WEB%/%TOPIC%?rev1=1.10&rev2=1.9) | [r1.9](../../view/%WEB%/%TOPIC%?rev=1.9) | [&gt;](../../rdiff/%WEB%/%TOPIC%?rev1=1.9&rev2=1.8) | [r1.8](../../view/%WEB%/%TOPIC%?rev=1.8) | [&gt;](../../rdiff/%WEB%/%TOPIC%?rev1=1.8&rev2=1.7) | [r1.7](../../view/%WEB%/%TOPIC%?rev=1.7) | [&gt;...](../../oops/%WEB%/%TOPIC%?template=oopsrev&param1=1.10) \} <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@somewhereNOSPAM.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 <code>%SEARCH\{"str" ...\}%</code> 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 <code>%INCLUDE:"filename.ext"%</code> to <code>%INCLUDE\{"filename.ext"\}%</code> . (Previous syntax still supported. Change was done because of inline search syntax)
* [[PeterThoeny]] - 11 Feb 2000: New variable <code>%SCRIPTURLPATH%</code> / $scriptUrlPath containing the script URL without the domain name. Templates have been changed to use this variable instead of <code>%SCRIPTURL%</code> . This is for performance reasons.
* [[PeterThoeny]] - 11 Feb 2000: New variable <code>%SCRIPTSUFFIX%</code> / $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 <code>%EDITBOXWIDTH%</code> and <code>%EDITBOXHEIGHT%</code> 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 <code>%ATTACHLINKBOX%</code> 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]] <code>%HTTP\_HOST%</code> , <code>%REMOTE\_ADDR%</code> , <code>%REMOTE\_PORT%</code> and <code>%REMOTE\_USER%</code> .
* [[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 <code>%GMTIME%</code> variable that shows the current GM time.
* [[CrisBailiff]], [[PeterThoeny]] - 21 Jun 2000: Fixed security issue to prevent a server side <code>%INCLUDE%</code> 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 <code>\*bold\*, _italic_, \_\_bold italic\_\_</code> and <code>**fixed**</code> , 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 <code>%INCLUDE\{"Web/TopicName.txt"\}%</code> to <code>%INCLUDE\{"Web.TopicName"\}%</code> . Legacy syntax still supported.
* [[PeterThoeny]] - 29 Jul 2000: New variables <code>%GMTIME\{"..."\}%</code> and <code>%SERVERTIME\{"..."\}%</code> . More in [[TWikiVariables]].
* [[PeterThoeny]] - 16 Aug 2000: New [[TWikiPreferences]] variables <code>%HTTP\_EQUIV\_ON\_VIEW%</code> , <code>%HTTP\_EQUIV\_ON\_EDIT%</code> and <code>%HTTP\_EQUIV\_ON\_PREVIEW%</code> that define the `<meta http-equiv="...">` meta tags for the TWiki templates. This can be used for example to set a document expiration time.
* [[PeterThoeny]] - 19 Aug 2000: Ref-By link searches all webs (not just the current web.)
* [[AlWilliams]], [[ManpreetSingh]], [[PeterThoeny]] - 18 Sep 2000: Added forced internal links. Write <code>[[text formatting FAQ]]</code> to get the link [[TextFormattingFAQ]] that points to topic [[TextFormattingFAQ]].
