# Chamilo 1.9.10 - Huánuco, 25th of January, 2015

### Release notes - summary

Chamilo 1.9.10 is a new minor version of the 1.9.x branch, with many bugfixes and a few interesting new features (as such, you can just overwrite previous files to upgrade from 1.9.8, 1.9.8.1 or 1.9.8.2 to 1.9.10).

### Release name

Huánuco is a small city in the Peruvian Andes, Northeast of Lima. This is a special version in memory of our cherished development team member César Perales, who passed away on July 22nd, 2014, at age 27. César contributed mostly "in the shadow" to Chamilo LMS, allowing the rest of the team to contribute more actively. He was a vibrant young man. He will be missed. César lived in calle Huánuco, in La Molina, Lima, Peru, where other team members bid him their last farewell for his last, eternal trip.
To this image, this version marks a change of behaviour from the Chamilo team, maturing into another plane of existence. This year, Chamilo LMS got used in more contexts than ever before, with a growth that is superior to any other open source LMS out there. It has become a more reliable and versatile platform, that will serve its purpose, helping making education better and more widely available, better than ever before.

### Security fixes

All security issues are published and patches are attached on our security issues page. If you think you found an additional security issue you'd like to report, please check our procedure there.

- (8a75f65 - #7242) Fix SQL injection in mySpace/users.php
- (d64a02c1 - #7272) Fix SQL injection threats and replace SESSION variable with api_get_user_id
- (58796166 - #7275) Add security token to course copy tool
- (#7440) Fix a series of SQL injection vulnerabilities due to integer filtering

### Possibly breaking changes

Two changes have been made to the forum tool code, which might make some of your forums disappear and require a direct database intervention.
First case: If you use forums with sessions and have placed a session forum inside a base-course forum category, the forum category will now no longer appear in any session, and as such, the session forums contained in that category will disappear. You can easily fix that by checking the c_forum_forum table for any record with session_id != 0 that points to a forum category that has session_id == 0. This is related to issue #7264.
Second case: In very rare occasions, if you use group forums and have had issues with posts appearing twice, then this release will fix this bug, but might also make some forum posts disappear. Although we could not reproduce the error, you should be able to fix it by changing the group_id column inside the c_forum_thread table. This is related to issue #7267
This is an exceptional event in the history of Chamilo, and we believe it should only affect very few portals, but we prefer to take precautionnary measures and warn you upfront.

# Chamilo 1.9.8.2 - 21st of June, 2014

### Release notes - summary

Chamilo 1.9.8.2 is a very little patch version with one bugfix regarding the learning paths tool. Considering the fact that 1.9.8 is planned for the long term, we'd hate to have such a minor patch left on the side for a year or so. This will be packaged and promoted as 1.9.8, but the folder inside the 1.9.8 will be called 1.9.8.2, with a change to this changelog file and a one-line change to main/newscorm/learnpathItem.class.php (as such, you can update just this file to upgrade from 1.9.8.1 to 1.9.8.2. See the code change for detais.

# Chamilo 1.9.8.1 - 18th of June, 2014

### Release notes - summary

Chamilo 1.9.8.1 is a patch version with one security patch on top of 1.9.8 (in the included library for FCKeditor). Please check our security issues page for more information.

# Chamilo 1.9.8 - Thon, 15th of June, 2014

### Release notes - summary

Chamilo 1.9.8 is a minor stable version with a series of improvements on top of 1.9.6.
This version is the first Chamilo version to drop support for Internet Explorer 7. We insist that you recommend your users to use modern browsers that respect web standards. If they *cannot* avoid Internet Explorer, make sure they use at least version 10, which respects a little bit more than half of the W3C standards (but still much less than Firefox, Chrome, Opera or even Safari)

### Release name

Thon is a small city in the Belgian region of Wallonia, several times classified as the most beautiful village of the South region of Belgium. It is a quite, beautiful place without anything out of the ordinary but made of beautiful, hundred years old homes built from famous Wallonia blue stone and crossed by the Samson river. Its stability and it's position just next to the large cliffs surrounding the Meuse are symbolically close to Chamilo 1.9.8, highly stable but a few steps away for the huge jump to the next major version.

### Security

All security issues are published and patches are attached on our security issues page. If you think you found an additional security issue you'd like to report, please check our procedure there.

- Patches have been applied to one of the packages of FCKEditor used for image uploads in Chamilo 1.9.6.1. These patches are included in 1.9.8 (see issues 11 and 12)
- Some other possible XSS attack vectors through initially privileged access have been fixed (see issue #13)

### Stylesheets and theming

Stylesheets have been considerably changed in version 1.9.8, which might require a little update on your side if you have a custom stylesheet. We're sorry about it, but it was really necessary to improve the adaptability of the interface for mobile devices (which we are sure you will appreciate). If you only changed the logo, we recommend you make a copy of an existing Chamilo style (main/css/chamilo*) again, rename it and simply replace the logo then upload the new style. If you have more complex styles, you might want to ask for the assistance of your web designer at the moment you update Chamilo to this version.

- (#7180) Remove custom_tab_* feature

# Chamilo 1.9.6.1 - 22th of May, 2014

### Release notes - summary

Chamilo 1.9.6.1 is a patch version with security patches on top of 1.9.6. Please check our security issues page for more information.

# Chamilo 1.9.6 - Rochefort, 4th of June, 2013

### Release notes - summary

Chamilo 1.9.6 is a minor stable version with security patches and a series of improvements on top of 1.9.4.

### Release name

Rochefort is a small city in the South of Belgium, that has existed at least since year 1041 and has shown impressive resilience and stability, which we think 1.9.6 has reached as well. Rochefort's Brewery produces a very nice trappist beer exported even to Peru! As we are getting ready for a larger battle, getting Chamilo LMS every day to a larger community, we thought we'd make a last quiet stop and salute the little town where several contributors of Chamilo have set foot in the past.

### Release notes - summary

### Release notes - summary

Chamilo 1.9.2 is a minor stable version with a series of improvements on top of 1.9.0.

### Style changes

Due to the move to HTML5, it is very likely that any older stylesheet will have to be updated when upgrading to Chamilo 1.9.

- Styles changed for all forms
- New top bar added (only for admins)
- Responsive layout for Mobile Devices

### Security

- If you haven't updated to 1.8.8.6 previously, then you will benefit from 1.8.8.6's security patches by installing 1.9.

### Known issues

- Document title: 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.
- 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
- 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
- Exercises: When reviewing an exercise, hotspot questions results are not remembered see #3980
- 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.

### Third-Party Libraries additions/updates

- Fullcalendar js library version 1.5.2
- Twig Template system added
- Twitter Bootstrap CSS Framework
- More libraries were added but haven't been properly registered at this time...

### Removals

- Removed deprecated "search" plugin (used to work with MnoGoSearch but hasn't been used for years to our knowledge - was successfully replaced by Xapian)
- 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.
- Removed the "Use document title" option - now we force users to use a document title - this avoids many issues with documents names - see #3781

# Chamilo 1.8.8.6 - Rottweil, 20th of July 2012

### Release notes - summary

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 our security issues listing page. 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

#### Why Rottweil?

Rottweil is a small medieval German town 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.

### Fixes

- Fixed long-standing e-mail sending bug (fixed in upstream and documented on the forum and all over the internet)
- Fixed a reflected XSS PHP_SELF security flax in the phpdocx 3rd-party library - #5202
- Fixed an unauthorized file deletion in dropbox by logged in users - #5202
- Fixed XSS unfiltered input in dropbox - #5202

- 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.
- 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.

### Known issues

- Groups (admin only): When a user is subscribed in a Course through a Group and he's also subscribed in the same Course (traditional way), when removing the user from the Group, the user will be also removed from the Course in both levels.
- Changed "givenname" for "cn" in LDAP queries. This might break some of the previous implementations of this plugin
- 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.

### Security

- Fixed more than 10 potential low-impact security issues in wiki (see our security page for details).

### Known issues

- 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.
- Changed "givenname" for "cn" in LDAP queries. This might break some of the previous implementations of this plugin
- 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.
- 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)
- Document tool: when moving an HTML file using the "move" functionality, images, videos and any incrusted file in that HTML will not be moved automatically see #1278
- Hotpotatoes: When taking a Hotpotato exam added to Chamilo there is a javascript error, this bug can be only reproduced using Google Chrome see #3332

### Deprecated features

In order to maintain a sufficient level of stability and push innovation forward, we have decided to officially drop support for specific features. This doesn't mean that they won't work anymore, but it indicates that they will cease being improved slowly, until we do not feel anyone is using them, at which point (probably several years afterwards) we will remove them from the code.
If you feel like a feature listed here is of major importance to you, you can either take the maintenance of this feature officially in charge by contacting us at info@chamilo.org or you can hire the services of one of our official providers (see our website, Support tab).

- Legacy classes - There is now new code to combine classes with the sessions feature or with the courses in a cleaner, more efficient way. We invite you to switch to session mode and rebuild your classes through the new "Class" option in the sessions block and let us know how that works our for you.
- Virtual courses - This feature has long been deprecated and we doubt any of our user is using it. If you are, please find another mechanism that suits your needs for that.

### Deprecated files

- main/garbage/ directory
- main/app_share/ was previously the experimental directory for a screen sharing application never deeply implemented. Use BigBlueButton instead, now.

### CSS changes

- CSS factorization - putting all common CSS to main/css/base.css see #3163
- CSS factorization - putting all common CSS classic styles into main/css/base_classic.css see #3163
- CSS factorization - putting all common CSS chamilo_XXX styles into main/css/base_chamilo.css see #3163

# Chamilo 1.8.7 - Istanbul

### Release notes - summary

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 highly recommend PHP 5.2 or superior, and require PHP 5.1 or higher.
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

### New Features

- Full UTF-8 support has been implemented (Feature #272)
  - UTF-8 becomes recommended system encoding to be used. It is also recommended that HTML-documents created with external tools be UTF-8 encoded.
  - 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.
  - 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.
  - Note about integration with external systems: 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.
- Class attendance (usable in Gradebook), which allows b-learning teachers to keep attendance registers
- Student certificates allow teachers to build certificates in their own format, using online-built HTML templates
- Thematic/Academic progress (shown on course homepage), which allows teachers to show how their courses is progressing following a pre-established schedule

# Dokeos 1.8.6.1 - August 2009

### Release notes - summary

Dokeos 1.8.6.1 is a minor release including just a few new features, mostly focused on internationalization, and several bugfixes.

### New Features

- Implemented new sub-language feature by which language terms redefinition becomes possible through the admin section (FS#4321)
- Admin: Terms and conditions added DT#4320
- Improvements in document tool, allow seeing glossary terms (FS#4337)
- Small improvements in SCORM export(FS#4300)
- At the beginning of the installation script, added an imperative check for PHP 5 has been added. (FS#4296)
- 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)
- 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)
- An internationalization option has been added for improving sorting in arbitrary language. When the intl 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)
- Installation script: The page about system requilements has been updated. Also, at the very beginning, a check has been added whether the mbstring php-extension is installed - see the related forum topic. (FS#306)
- A new php-based configuration for the online editor has been implemented, see dokeos/main/inc/lib/fckeditor/myconfig.php. Also, toolbar definitions have been split in separate php-files within the directory dokeos/main/inc/lib/fckeditor/toolbars/ . Customization of the editor is more convenient and flexible now. (FS#2867)
- Online editor: A upgrade from FCKEditor 2.6.4 to FCKEditor 2.6.4.1 has been implemented. (FS#4383)
- Online editor: Blocking copy/paste for trainees has been added. The feature is configurable through editing the toolbar definition files within the directory dokeos/main/inc/lib/fckeditor/toolbars/ . (FS#2867)
- Online editor: Preview tabs have been added to the dialogs for inserting video, flv-video, and YouTube video. (FS#2867)
- Online editor: The audio 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)
- 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)
- Online editor: Configuration of the mimetex plugin has been reworked to gain simplicity. The procedure for configuration has been updated, see the related forum topic. (FS#2867)
- Online editor: A new asciimath plugin for inserting mathematical formulas has been added. It is based on the ASCIIMathML.js library. (FS#2867)
- Social: Added possibility to define RSS feeds inside personal page of social network (need to define an 'rssfeeds' extra user text field)

### Debugging

- Online editor: Several known bug-fixes from FCKEditor 2.6.5 SVN have been implemented, tickets #1537, #2156, #2689, #2821, #2856, #2874, #2915, #3120, #3181, #3427, #3429, #3439, #3446, #3481, #3677, #3818, #3880, #3925. (FS#2867)
- Online editor: The toolbar icons have been upgraded to those from FCKEditor 3.0. (FS#2867)
- A solution has been implemented for fixing the "__flash__removeCallback" bug, which affects the media player on Internet Explorer browser. (FS#4378 and FS#2867)
- Quiz: fixed bug in multiple-choice/single-answer questions results (whereby the wrong answer was saved)
- Admin: Added courses from sessions inside AJAX popup of courses list in users list (SVN#22398)
- Admin: Showing full-length course titles in list of courses while adding to sessions(SVN#22399)
- Admin: Added session name in title of session edition pages(SVN#22400)

### CSS changes

- Sticky footer now available in all Dokeos stylesheets. If you own a custom stylesheet you will need to update it, see DT#3549 for further details.

### Known issues

### Deprecated files

- The whole main/inc/lib/fckeditor/editor/filemanager/browser/default/connectors/ directory should be removed for security reasons
