<p><ahref="http://en.wikipedia.org/wiki/Hanga_Roa">Hanga Roa</a> is the capital city of Rapa Nui, the Easter Island. The entire Rapa Nui culture is filled with mystery and assumptions about where and how the first Rapa Nui people came to be on the island, but it is accepted by many that the main strain came from Polynesia a long time ago. The population there is around 3,300 but warmly welcomes tons of tourists every year, a bit in the image of the small team of Chamilo now serving more than 1.4M users worldwide, with a welcoming 1.9.2 version that will help you get more time to yourself...</p>

<li>Tracking: Reporting-sessions: division by zero on closed course (#4860)</li>
<li><b>Document title:</b> The option to NOT use a document title different than the filename in the documents tool has been removed. This means that if this setting was not set to the default option in your Chamilo option or if you have a very old installation that you have been upgrading over the years, you might experience problems accessing the documents. In this case, we recommend contacting an official provider of Chamilo to take this migration in charge.</li>
<li>During upgrade, if your database ends with "c_", the installation process will report errors in the PHP error log. This is due to a check on the new c_id field for database normalization, but is not important. The corresponding logging code can be disabled in database.lib.php</li>
<li>Agenda regression: because we implemented a much more usable and familiar agenda for most of you, and because we lacked some time to go into the details, we have temporarily removed the possibility to make an event visible to specific users (they are always visible to all the course users right now) - see task #5201 for details</li>
<li>Exercises: When reviewing an exercise, hotspot questions results are not remembered see #3980</li>
<li>Learning paths: Copying a learning path with embedded documents and exercises from one course to another might cause resource linking problems (images, audio, etc). We recommend copying the complete course and then removing unnecessary elements, or exporting the learning path as SCORM.</li>
<li>Removed deprecated "search" plugin (used to work with MnoGoSearch but hasn't been used for years to our knowledge - was successfully replaced by Xapian)</li>
<li>Removed the RED5 installation guide from the documentation directory: the supported BigBlueButton videoconference system provides its own installation manual, linked from the Chamilo admin guide.</li>
<li>Removed the "Use document title" option - now we force users to use a document title - this avoids many issues with documents names - see #3781</li>
<h1>Chamilo 1.8.8.6 - Rottweil, 20th of July 2012</h1>
<h3>Release notes - summary</h3>
<p>Chamilo 1.8.8.6 is a minor security fix, stable version for version 1.8.8.4. If you are using Chamilo 1.8.8.4, we highly recommend you upgrade to this version, either by following the usual upgrade procedure, or by applying a very small patch, as explained on <ahref="http://support.chamilo.org/projects/chamilo-18/wiki/Security_issues">our security issues listing page</a>. The security fixes are all considered "moderate". This means you could loose data (specifically dropbox tool data in this case) and your users might get tricked into providing credentials to potential hackers, but the integrity of your server will not be in direct danger. 1.8.8.6 was developed in a separate branch, but fixes were applied to the 1.9 branch, which means 1.9 can be considered as the follower of 1.8.8.6 as much as of 1.8.8.4. If you have 1.8.8.4, migrating to 1.9 will effectively remove the need for migrating to the intermediary step of 1.8.8.6</p>
<h4>Why Rottweil?</h4>
<p><ahref="https://maps.google.com/maps?q=48.167352,8.627969&hl=fr&ll=48.167352,8.627969&spn=0.006054,0.016512&sll=48.167352,8.627969&sspn=0.006054,0.016512&t=h&z=17">Rottweil</a> is a <ahref="http://en.wikipedia.org/wiki/Rottweil">small medieval German town</a> where the occasional tourist might feel very relaxed and secure. This feeling is increased by the obviously-difficult-to-attack strategical position. Considering the security-only aspect of this release, we wanted a small city name that would represent this more secure aspect. Rottweil has been visited by one of our team members in the past... that's all it takes.</p>
<h3>Fixes</h3>
<ul>
<li>Fixed long-standing e-mail sending bug (fixed in upstream and documented on the forum and all over the internet)</li>
<li>Fixed a reflected XSS PHP_SELF security flax in the phpdocx 3rd-party library - #5202</li>
<li>Fixed an unauthorized file deletion in dropbox by logged in users - #5202</li>
<li>Fixed XSS unfiltered input in dropbox - #5202</li>
<li>Added quick browsing of directories' documents - requires manual activation for now: in user_portal.php, find $load_dirs and set to $load_dirs = true;. Will be setable through admin page in next version (changeset 7f84869233c2)</li>
<li>Certificates: An easy to remember URL to view students URL: http://campus.chamilo.org/certificates/?id=123 (public for everyone right now) see #3630</li>
<li>Certificates: QR code generation for certifications #3631</li>
<li>Made assignments editable/removable by students only until they have been reviewed and scored (> 0) by the teacher (changeset bc1b8e1e603d)</li>
<li>Watermark portal images are now saved in the main/default_course_document/images/ folder. If you used portal-wide watermarks before, you might need to upload the watermark image again.</li>
<li>A style-specific switch had been added in 1.8.8.2, which improved the appearance of older style but went against MVC's principles and broke copies of Chamilo-based styles. This switch has been removed, which may lead to the breadcrumb in non-chamilo-based styles to appear as less attractive, but keeps the MVC model safe so anyone can modify the appearance safely from the CSS. This might require very little cosmetic changes from you (in your style's default.css file), but we believe it's for the best.</li>
<li>Thematic progress do not show on course homepage anymore (#3505)</li>
<li>Scoring users contribution in forum broken (#3504)</li>
<li>Can't add hotpotatoes to a course anymore (#3469)</li>
<li>Promotions copy replicates sessions several times (#3465)</li>
<li>Glossary broken with new yoxview (#3464)</li>
<li>Courses missing from user_portal.php after upgrade (#3419)</li>
<li>Learning path icon does not appear in iPad view (#3413)</li>
<li>Sorry, you are not allowed on admin settings (#3265)</li>
<li>Learning path mini panel does not show progress in IE7 (#3116)</li>
<li>Series of little visualisation bugs (#2493)</li>
<li>For other changes see 1.8.8 changelog below</li>
</ul>
<h3>Security</h3>
<ul>
<li>Fixed several limited-risk potential XSS.</li>
<li>For other changes see 1.8.8 changelog below</li>
</ul>
<h3>Known issues</h3>
<ul>
<li>Groups (admin only): When a user is subscribed in a Course through a Group and he's also subscribed in the same Course (tradional way), when removing the user from the Group, the user will be also removed from the Course in both levels.</li>
<li>Changed "givenname" for "cn" in LDAP queries. This might break some of the previous implementations of this plugin</li>
<li>If you used split users directories before v1.8.8 in combination with the "My files" feature (if it existed at all at that point), you will probably have a problem now, as the code in the previous version was wrong and was saving the personal portfolio file in another directory than the user's. Sorry about that. If you need professional assistance, see the http://www.chamilo.org/ website under support -> professional support for official providers who could help you. And don't forget to keep a backup. If you don't understand a thing about what I'm talking about, you are probable not concerned by this bug, so don't worry too much.</li>
<li>Document tool: when moving an HTML file using the "move" funcionality, images, videos and any incrusted file in that HTML will not be moved automatically see #1278 </li>
</ul>

This plugin uses the library file chamilo/main/inc/lib/asciimath/ASCIIMathML.js which has combined functionality ASCIIMathML + ASCIIsvg (Feature #2132)</li>
<li>"ASCIIMathML mathematical editor" - activates the plugin for inserting mathematical formulas;</li>
<li>"Mathematical graphics editor ASCIIsvg" - activates the plugin for inserting mathematical graphs;</li>

<li>For some reason, we have been reported unsuccessful migrations from 1.8.7 to 1.8.7.1 whereby the course_rel_user table was not integrally copied. We recommend keeping your database backup until you're sure every student/course relationship was copied (comparing the lines in the table before and after migration might help you)</li>

<p>Chamilo 1.8.7 is a major release including a lot of new features, mostly focused on social network, the handling of sessions (which will help many educational institutions, public or private, to manage their contents in a more flexible way) and visual style, and a few important bugfixes. It lays the first stable stone in the Chamilo software project. This version is the first one to <b>highly recommend PHP 5.2</b> or superior, and <b>require PHP 5.1</b> or higher.<br/>Also, this version of Chamilo will automatically convert all your data to UTF-8, which will make it more difficult to migrate from Dokeos versions higher than 1.8.6.1</p>
<li>Full UTF-8 support has been implemented (Feature #272)<ul>
<li>UTF-8 becomes recommended system encoding to be used. It is also recommended that HTML-documents created with external tools be UTF-8 encoded.</li>
<li>For newly installed systems: UTF-8 is the default value of the administrator's setting "Character set". Database tables will now be storing UTF-8 encoded text.</li>
<li>For upgraded systems: The upgrade procedure automatically changes the character set to UTF-8. During upgrade database tables are converted to UTF-8 and the corresponding changes to text fields are applied. Conversion to UTF-8 of HTML documents stored in the file system is not performed, this is not mandatory.</li>
<li><em>Note about integration with external systems</em>: Keep in mind that since version 1.8.7, pieces of text kept in the database are UTF-8 encoded. If an external system accesses database records directly, some corrections to contents of the external database might be necessary.</li>
<li>Thematic/Academic progress (shown on course homepage), which allows teachers to show how their courses is progressing following a pre-established schedule</li>
<li>HR dashboard: statistical reporting page (by blocks) about students, courses or sessions, available to platform administrator, session administrator or human resources manager</li>
<li>Fixed major course copy drawback by which exercise contents were keeping links to the old course (thanks to Ludovic Gasc and SANTEXCEL - BT#658)</li>
<li>Some PHP short tags fixed. Reported by Sicabol, see <ahref="http://www.chamilo.org/node/114"target="_blank">http://www.chamilo.org/node/114</a> (Feature #347)</li>
<li>Fixed bug reported by Carlosbrolotobar in <ahref="http://www.chamilo.org/node/135"target="_blank">http://www.chamilo.org/node/135</a> whereby normal students don't can't see their social profile section in the right menu if they can't see the courses catalog.</li>
<li>Corrected mailing functions, now they load the file <em>mail.conf.php</em>. Previously the file <em>mail.conf.dist.php</em> was to be loaded by mistake. (Feature #272)</li>
<li>Online editor: A new configuration option about editor's background has been proposed by Wofganag Schneider and it has been implemented. See <ahref="http://www.chamilo.org/node/107"target="_blank">http://www.chamilo.org/node/107</a> (Feature #347)</li>

<li>Fixed Added an option to cancel prerequisites in a course (Learning path). Fixed by aboivin in <ahref="http://www.chamilo.org/node/146"target="_blank">http://www.chamilo.org/node/146</a></li>

<li>Core API: Support has been implemented for json_encode() function for PHP version < 5.2. The correspondent bug-report "Hide and show not working" and testing have been done by Hubert Borderiou <ahref="http://support.chamilo.org/issues/761"target="_blank">http://support.chamilo.org/issues/761</a></li>
<li>Announcement tool: display images inside content of announcement sent by email (now the attachment images are embedded inside content) - private BT#925</li>
<li>When installing the platform will be active by default the following options: Allow edit tutors in the courses of the sessions, social network and sending messages</li>
<li>Timezone functionality is not available in the most recent versions of PHP available for CentOS/RHEL ( 5.1.6-23.2.el5_3 ) (see http://www.php.net/manual/en/function.timezone-identifiers-list.php). Chamilo now requires PHP 5.1 or superior and <b>highly</b> recommends PHP 5.2.</li>
<li>When the user publishes an event as announcement, this same announce can be repeat many times</li>
<p>Chamilo 1.8.6.2 is a intermediate release including a lot of new features, mostly focused on social network, the handling of sessions (which will help many educational institutions, public or private, to manage their contents in a more flexible way) and visual style, and a few important bugfixes. It lays the first stable stone in the Chamilo software project.</p>
<li>Reporting: the additional user profile fields (defined by the platform administrator through platform administration > profiling) can now be shown in the reporting screens</li>
<li>Subscribing users in a course: you can now filter on addtional user profile fields when subscribing a user in a course (through user/subscribe_user.php) </li>
<li>Added an immediate redirection to the course after login when a user is enrolled only in one course (defined by the platform administrator through platform administration > configuration settings > training)- DT#3466</li>
<li>Added user's photo into users list interface - DT#5496</li>
<li>Disabled trainer/tutor name field in create course form, set to current user's name by default. Can be modified into course settings - DT#5496 </li>
<li>If the "Show glossary terms" option is selected for the lessons tool (SCORM) and exercises, the description of the exercise might contain the answers to the question. Need human intelligence to avoid this.</li>
<li>When the system Dokeos is switched into "Test server" mode, a clickable indicator appears in the footer. This indicator is visible by platform administrators only. (FS#4341)</li>
<li>A transliteration function has been added. Currently, it is used in uploading files. Files with non-English names get names that contain ASCII letters only, remaining readable in the corresponding language. Rationale: The PHP5 run-time environment does not manage file name encodings, adding such a non-native feature involves too much work. For avoiding character encoding problems, transliteration of file names is the possible solution. (FS#306)</li>
<li>An internationalization option has been added for improving sorting in arbitrary language. When the <ahref="http://php.net/manual/en/book.intl.php"target="_blank">intl</a> php-extension has been installed, various sorting routines exploit it for better sorting. Rationale: The PHP5 run-time environment does not provide native and reliable way of sorting UTF-8 strings. (FS#306)</li>
<li>Installation script: The page about system requilements has been updated. Also, at the very beginning, a check has been added whether the <ahref="http://php.net/manual/en/book.mbstring.php"target="_blank">mbstring</a> php-extension is installed - see <ahref="http://dokeos.com/forum/viewtopic.php?t=29548"target="_blank">the related forum topic</a>. (FS#306)</li>
<li>A new php-based configuration for the online editor has been implemented, see <i>dokeos/main/inc/lib/fckeditor/myconfig.php</i>. Also, toolbar definitions have been split in separate php-files within the directory <i>dokeos/main/inc/lib/fckeditor/toolbars/</i> . Customization of the editor is more convenient and flexible now. (FS#2867)</li>
<li>Online editor: Blocking copy/paste for trainees has been added. The feature is configurable through editing the toolbar definition files within the directory <i>dokeos/main/inc/lib/fckeditor/toolbars/</i> . (FS#2867)</li>
<li>Online editor: Preview tabs have been added to the dialogs for inserting video, flv-video, and YouTube video. (FS#2867)</li>
<li>Online editor: The <strong>audio</strong> plugin has been activated by default as an implementation of the "Insert audio / Audio properties" dialog. This new plugin is intended to replace the "MP3" plugin. (FS#2867)</li>
<li>Online editor: The simple file manager, the advanced file manager and the image manager have been integrated by default with the editor's dialog system. Thus, they work faster and in a more secure way. (FS#2867)</li>
<li>Online editor: Configuration of the <strong>mimetex</strong> plugin has been reworked to gain simplicity. The procedure for configuration has been updated, see <ahref="http://www.dokeos.com/forum/viewtopic.php?t=29594"target="_blank">the related forum topic</a>. (FS#2867)</li>
<li>Online editor: A new <strong>asciimath</strong> plugin for inserting mathematical formulas has been added. It is based on the <ahref="http://mathcs.chapman.edu/~jipsen/mathml/asciimath.html"target="_blank">ASCIIMathML.js</a> library. (FS#2867)</li>
<li>A solution has been implemented for fixing the <ahref="http://bugs.adobe.com/jira/browse/FP-529"target="_blank">"__flash__removeCallback" bug</a>, which affects the media player on Internet Explorer browser. (FS#4378 and FS#2867)</li>
<li>Sticky footer now available in all Dokeos stylesheets. If you own a custom stylesheet you will need to update it, see <ahref="https://bts.dokeos.com/issues/show/3549">DT#3549</a> for further details.</li>
