**History of the TWiki Implementation (version %WIKIVERSION%)**
* [[Main/PeterThoeny]] - 23 Jul 1998: Installed initial version, based on the JOS Wiki. See [[WikiWikiClones]] for details.
* [[Main/PeterThoeny]] - 27 Jul 1998: Added automatic links to topics in other TWiki webs by specifying <web name>.<topic name>, e.g. `Know.WebSeach` .

* [[Main/PeterThoeny]] - 28 Jul 1998: Topic [Changes](%SCRIPTURL%/changes/Main) 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]].
* [[Main/PeterThoeny]] - 28 Jul 1998: Added TWiki variables, enclosed in % signs: %TOPIC% (Topic name), %WEB% (web name), %SCRIPTURL% (script URL), %DATE% (current date), %WIKIWEBMASTER% (Wiki webmaster address), %WIKIVERSION% (Wiki version), %USERNAME% (user name), %WIKIUSERNAME% (Wiki user name).
* [[Main/PeterThoeny]] - 31 Jul 1998: Support for quoted text with a '>' at the beginning of the line.
* [[Main/PeterThoeny]] - 04 Aug 1998: Warn user if new topic name is not a valid Wiki name. (template file templates/Web/notwiki.tmpl)
* [[Main/PeterThoeny]] - 04 Aug 1998: Separate templates for text of non existing topic and default text of new topic. (template file templates/Web/notedited.tmpl)
* [[Main/PeterThoeny]] - 05 Aug 1998: Signature and date is inserted automatically when creating a new topic.
* [[Main/PeterThoeny]] - 06 Aug 1998: Added server side include of files. Syntax is %INCLUDE:"filename.ext"%
* [[Main/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.
* [[Main/PeterThoeny]] - 13 Aug 1998: [[WikiNotation]] allows also numbers after the `AaA` sequence, e.g. `AaA1` is a valid [[WikiTopic]] name, but not `Aa1`.
* [[Main/PeterThoeny]] - 24 Sep 1998: Corrected templates for automatic email notification so that MS Outlook can display attachment as an HTML file.
* [[Main/PeterThoeny]] - 13 Oct 1998: Alphabetical topic index in [[WebSearch]].
* [[Main/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.
* [[Main/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.
Topic TWikiHistory . \{ Edit | Ref-By | r1.3 | r1.2 | r1.1 \}
Revision r1.3: 1998/10/26 01:34:00 by [[PeterThoeny]]
* [[Main/PeterThoeny]] - 26 Oct 1998: Added preview of topic changes before saving the topic. This was necessary to prevent unneeded revisions.
* [[Main/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:
Topic TWikiHistory . \{ Edit | Ref-By | r1.3 | > | r1.2 | > | r1.1 \}
Revision r1.3: 1998/11/10 01:34 by [[PeterThoeny]]
* [[Main/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.
* [[Main/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.
* [[Main/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.
* [[Main/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.

* [[Main/PeterThoeny]] - 15 Jul 1999: Search path for include files in %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.
* [[Main/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` .

a table |
with |
cells |

* [[Main/PeterThoeny]] - 03 Oct 1999: Limit the number of revisions shown at the bottom of the topic. Example:
Topic %TOPIC% . \{ ..... | [Diffs](../../rdiff/%WEB%/%TOPIC%) | r1.10 | [>](../../rdiff/%WEB%/%TOPIC%?rev1=1.10&rev2=1.9) | [r1.9](../../view/%WEB%/%TOPIC%?rev=1.9) | [>](../../rdiff/%WEB%/%TOPIC%?rev1=1.9&rev2=1.8) | [r1.8](../../view/%WEB%/%TOPIC%?rev=1.8) | [>](../../rdiff/%WEB%/%TOPIC%?rev1=1.8&rev2=1.7) | [r1.7](../../view/%WEB%/%TOPIC%?rev=1.7) | [>...](../../oops/%WEB%/%TOPIC%?template=oopsrev¶m1=1.10) \}
Additional revisions can be selected by pressing the `>...` link.
* [[Main/PeterThoeny]] - 10 Jan 2000: No more escaping for '%' percent characters. (Number of consecutive '%' entered and displayed is identical.)
* [[Main/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. .
* [[Main/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.
* [[Main/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.)
* [[Main/PeterThoeny]] - 07 Feb 2000: Inline search. New variable %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.
* [[Main/PeterThoeny]] - 07 Feb 2000: Changed the syntax for server side include variable from %INCLUDE:"filename.ext"% to %INCLUDE\{"filename.ext"\}% . (Previous syntax still supported. Change was done because of inline search syntax)
* [[Main/PeterThoeny]] - 11 Feb 2000: New variable %SCRIPTURLPATH% / $scriptUrlPath containing the script URL without the domain name. Templates have been changed to use this variable instead of %SCRIPTURL% . This is for performance reasons.
* [[Main/PeterThoeny]] - 11 Feb 2000: New variable %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".
* [[Main/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 [[TWikiUsers]]). With this, discontinue use of server side include of `wikiwebs.inc` , `wikiwebtable.inc` , `weblist.inc` , `webcopyright.inc` and `webcolors.inc` files.

* [[Main/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 %ATTACHLINKBOX% controls the default state of the **_link_** check box in the attach file page.
* [[Main/JohnAltstadt]], [[Main/PeterThoeny]] - 21 Apr 2000: [[TWikiRegistration]] is done separately for Intranet use (depends on remote\_user) or Internet use (depends on .htpasswd file).
* [[Main/PeterThoeny]] - 21 Apr 2000: New [[TWikiVariables]] %HTTP\_HOST% , %REMOTE\_ADDR% , %REMOTE\_PORT% and %REMOTE\_USER% .
* [[Main/KevinKinnell]] - 02 May 2000: Advanced search (under construction)
