edb7d5ad 3
4=== 3.8 ===
6* The PHP Less compilier has now been removed from the core library.
7 Please consider migrating your theme to use SCSS.
9=== 3.7 ===
10* The core/form_autocompelte_input template now has a `data-tags` attribute.
11* Boost theme renderer overrides have now been migrated to core.
12* Renderers that were overridden by Boost are now in Bootstrapbase
13* Core templates in Boost have now moved into core
14* Templates that were overridden by boost are now located in Bootstrapbase
a5a6df54 15* Themes bootstrapbase, clean & more have now been removed.
e994dea0 16
17=== 3.6 ===
19* A new callback has been added to the theme layout files allowing plugins to inject their content
20 into the page. For Boost it was added as a mustache variable "{{{ output.standard_after_main_region_html }}}" in
21 templates/columns1.mustache and templates/columns2.mustache. In bootstrapbase it was added as a
22 function call "$OUTPUT->standard_after_main_region_html()" in layout/columns1.php, layout/columns2.php.
23 and layout/columns3.php. Child themes not inheriting these templates should add the function call
24 after the div containing the main content region. Please refer to the messaging drawer UI for an example of
25 making use of this new feature.
26* The body tag has various browser-specific classes for those cases where some
27 browser-sniffing is unavoidable. This used not to recognised Microsoft Edge,
28 but now it does (class 'edge'). Also, both Safari and Chrome used to be
29 class 'safari', but now there are separate classes 'safari' and 'chrome'.
30 The body's class should change to match the browser:
31 - Google Chrome (Mac & Window): The body class should change from safari to chrome.
32 - Google Chrome (Android) : The body class should change from safari, android to chrome, android.
33 - Microsoft Edge: The body class should change from safari to edge.
34 - Mobile safari: The class ios should exist, safari class should be removed.
35* Remove class .safari styling from activity chooser dialog for theme boost and bootstrapbase.
36* The following functions and classes have been finally deprecated and can not be used anymore:
37 * css_is_colour()
38 * css_is_width()
39 * css_sort_by_count()
db03bff7 40 * core_course_renderer::add_modchoosertoggle()
216b8947 41 * class css_optimiser
a266ae30 42
43=== 3.4 ===
45* There was a mustache template login.mustache in /lib/templates/ rendering the login form
46 and a template with the same name in /theme/boost/templates/ rendering the pagelayout "login".
47 To prevent misunderstanding when overriding one of these templates in a Boost child theme,
48 the first one was renamed to loginform.mustache - see MDL-58970.
49* The Boost flat navigation nodes now have several data-attributes which let plugin developers
50 access properties from the underlying navigation nodes in the browser - see MDL-59425.
51* Navigation between activities via a previous and next link was added to Boost, Clean and Bootstrapbase. This
52 is made possible by a new function core_renderer->activity_navigation().
53* Theme designers may now place the Reset tour on this page link where required by adding an empty
54 container (e.g. <div class="tool_usertours-resettourcontainer"></div>) to their layouts.
46676b76 55
56=== 3.3 ===
58* As boost-based themes no longer use the moodle-core-popuphelp help popups, the javascript
59 setup for this module have been moved from core standard_head_html to the bootstrapbase
60 renderer. If your theme needs this javascript you will need to ensure the bootstrap renderer
61 is called, or require the JS yourself
63=== 3.2 ===
65* Removed themes: base, canvas
66 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
67 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
68 the theme/ directory BEFORE UPGRADING.
2ede86d7 69* Bootstrap 4 was added as part of a the new theme 'boost'.
70* Some backwards and forwards compatibility has been added for different bootstrap versions.
71 This is to allow the same markup to work in "clean" and "boost" themes a lot of the time.
72 It is also to allow user text with bootstrap classes to keep working in the new theme.
73* Using .dir-rtl for RTL styling is deprecated and should not be used any more. From now
74 the styles are automatically flipped when the language is right-to-left. However,
75 as this is not always perfect, you can define exceptions. Please refer to the documentation
76 of the tool RTLCSS-PHP for more information: https://github.com/moodlehq/rtlcss-php
77* Themes can now automatically compile SCSS on the fly. This works the same way as it
78 does compiling LESS on the fly, effecitvely adding $THEME->scss to your config. The
79 latter can either be the name a SCSS file (without extension) in your theme's scss/ folder,
80 or a Closure which will return the main SCSS content.
81* Two new callbacks allow themes to inject SCSS code before and after the content provided
82 by the SCSS file $THEME->scss. See $THEME->prescsscallback and $THEME->extrascsscallback.
83* A new callback can be defined to post process the CSS using an object representation
84 of the CSS tree ($THEME->csstreepostprocess). This gives a lot more flexibility than a
85 simple find and replace. Refer to 'boost' for an example, and to PHP-CSS-Parser.
86 (https://github.com/sabberworm/PHP-CSS-Parser) for the API.
87* A new core setting now enables admins to upload the logos of their site. Using the
88 following methods, themers can instantly support branding logos without the need
89 to implement specific theme settings:
90 * $OUTPUT->get_logo_url($maxwidth, $maxheight);
91 * $OUTPUT->get_compact_logo_url($maxwidth, $maxheight);
92* The class .dir-ltr should not be used any more. To force LTR styles use the directive
93 to remove the rule when the language is RTL. See RTLCSS-PHP for more information.
94* A new class .text-ltr may be used to force the direction to LTR. This is especially useful
95 for forms fields (numbers, emails, URLs must not be RTL'd), and for displaying code
96 snippets or configuration samples.
9d1402ab 97* A new theme config 'requiredblocks' allows a theme to define which blocks are deletable.
98* You may no longer override the following core_course_renderer methods.
99 See course/upgrade.txt for more information:
100 - course_modchooser_module_types
101 - course_modchooser_module
102 - course_modchooser_title
103* The question chooser now uses a renderable and a template, the following methods
104 have been deprecated in favour of core_question_bank_renderer::render_qbank_chooser().
105 - qbank_chooser
106 - qbank_chooser_types
107 - qbank_chooser_qtype
108 - qbank_chooser_title
109* The 'css optimiser' has been removed. Developers are encouraged to use tools such as stylelint
110 to help optimise their css. Some functions and classes in lib/csslib.php (which was not for public use)
111 have been deprecated:
112 - css_is_colour
113 - css_is_width
114 - css_sort_by_count
115 - class css_optimiser no longer does anything.
116* CLI svgtool.php has moved from theme/base/cli to admin/cli and paths should be relative to the new location.
117* mod_chat will now display the 'course theme' option for all themes (previously it was only displayed on
118 bootstrap2 based themes).
119* Theme can choose how to display "Add a block" control in $THEME->addblockposition, default value is
120 BLOCK_ADDBLOCK_POSITION_DEFAULT that displays it as a fake block in editing mode.
2258b4dc 121
122=== 3.1 ===
124* A new search box for global search has been added to bootstrap and clean layout files, if
125 your theme is overwriting columns1.php, columns2.php or columns3.php you will need to add a
126 call to core_renderer::search_box to display it.
127* Notification templates have been renamed to better suit types of alert
128 rather than uses. The following changes have been made:
129 * notification_problem.mustache => notification_error.mustache
130 * notification_message => notification_info
131 * notification_redirect => notification_warning
132* Method core_course_renderer::course_section_cm_name() is split into two methods, custom themes that override
133 this method must be modified or otherwise editing functionality may become broken. This method is now also used by
134 social activities block and site menu block to display activities names.
4040c8b3 135
c7b73854 136=== 3.0 ===
138* The renderer function core_availability_renderer::multiple_messages was changed to
139 render_core_availability_multiple_messages, requiring a parameter of the new
140 \core_availability\multiple_messages type.
141* Meta description is now included in standard_head_html for homepage in bootstrapbase.
142 If your theme includes a meta description directly in a layout for the frontpage,
143 you will need to remove it or override the standard_head_html instead.
144* Themes Clean and More have been updated to use a new navbar_button function, which shows the
145 hamburguer icon (responsive menu) or not depending on custom and language menus settings;
146 themes extending bootstrapbase and overriding its layouts can call replace their "a.btn-navbar"
147 node for a call to this function.
c47f3803 148* Themes Clean and More page header logo only displays on front page and login page.
149* A new function navbar_home has been added to theme_clean and theme_more to display the navigation bar link
150 to the site home. Two new settings have been added to control if the link should be a small logo image, text
151 or both. It defaults to the current behaviour, only a text link.
c7b73854 152
153=== 2.9 ===
155* Themes Bootstrapbase, Clean and More have undergone some changes for RTL layouts see - MDL-48160.
c58891f1 157* Themes Clean amd More page header background logo, if loaded, no longer links to the home page.
158* Themes Clean and More have been updated to use the renderer full_header(). This renderer (when in a user context) displays a message button
159 and consequently the link to message users have been removed from various pages. It is recommended that theme developers use this
160 renderer to ensure that they do not suffer from a reduction in access to this feature.
161* $OUTPUT->context_header() has been introduced to produce headers similar to what full_header() creates. This renderer is used for creating
162 subsequent headers in a page. If provided with user information, this render will also display a message button like full_header().
c58891f1 163
c10fa5da 164=== 2.8 ===
c58891f1 165
166* Themes Base and Canvas layout/embedded.php has changed.
167 The div id="content" has been changed to id="page-content" - see MDL-47915.
168* All mod_assign CSS selectors have been qualified with ".path-mod-assign". This means any custom CSS
169 rules for mod_assign in a theme may need to be updated.
170* The following render methods were renamed, if you have overridden any of these you will need to update your renderer:
171 - report_log_renderer::render_report_log_renderable => report_log_renderer::render_report_log
172 - report_loglive_renderer::render_report_loglive_renderable => report_loglive_renderer::render_report_log
a2a4ad89 173* On calendar view screen the course selector and new event button have been swapped, custom CSS for .path-calendar might be affected.
174* The functions search_listing() and search_pagination() in the core_course_management_renderer class take the searched string
175 as an extra parameter - see MDL-46902.
f2b4b2ad 176* Themes with non-fixed headers must have the .navbar class in their navbar in order for floating headers in the grader report to work - see MDL-46658.
177* To accomodate the new gradebook, use of overflow: hidden or overflow-x: hidden CSS rules on DOM elements containing the
178 #user-grades table, visible at [Course administration -> Grades] is not recommended. Please use overflow: auto or
179 overflow: scroll instead, as this will handle medium to large courses with multiple activities better (more information available at https://docs.moodle.org/dev/Theme_upgrade_notes ).
180* The new user menu can be added to themes by calling $OUTPUT->user_menu(); we recommend doing so in a backwards-compatible way (see https://docs.moodle.org/dev/Theme_upgrade_notes for more information).
c10fa5da 181
182=== 2.7 ===
184* CSS related functions in theme class and csslib.php were refactored, addons that are
185 using this private API need to be updated
ba55be91 186* Please update your css to use 'tr:nth-of-type(odd/even)' instead of '.r0/.r1' to apply tr specific css for various tables.
187 These classes are deprecated now and will be removed in Moodle 2.9. This has done to better support styling tables that will be altered by JavaScript.
188 Here is an example to update your css:
189 Old code:
190 table.generaltable .r0 {background-color: #F0F0F0;}
191 table.generaltable .r1 {background-color: #F0F0F0;}
192 New code:
98396c23 193 table.generaltable > tbody > tr:nth-of-type(even) {background-color: #F0F0F0;}
ba55be91 194 table.generaltable > tbody > tr:nth-of-type(odd) {background-color: #F0F0F0;}
6b216432 195
196Removed themes:
197* afterburner, anomaly, arialist, binarius, boxxie, brick, formal_white, formfactor, fusion, leatherbound,
198 magazine, nimble, nonzero, overlay, serenity, sky_high, splash, standard and standardold have been removed.
199 During the upgrade process the themes will be uninstalled and all their settings will be deleted.
200 If you wish to keep your theme and its settings, download it from moodle.org and put it back in
201 the theme/ directory BEFORE UPGRADING.
6b216432 202
204* z-index on #dock has been adjusted from 11000 to 5000 to prevent overlapping issues with fullscreen TinyMCE in Base theme.
699e2fd0 206=== 2.6 ===
3b42864d 207
208Removed themes:
209* "My Mobile" theme has been removed (see MDL-40874).
210 During the upgrade process "My Mobile" theme will be uninstalled and all its settings will be deleted.
211 "My Mobile" theme and its extending themes will fallback to the mobile friendly "Clean" theme.
212 If you wish to keep "My Mobile" theme and its settings, BEFORE UPGRADING you can copy the files from the
213 unmaintained plugin into theme/mymobile.
214 The unmaintained plugin can be downloaded at https://moodle.org/plugins/pluginversion.php?id=4563
699e2fd0 215Notes:
faf6010b 216* There have been several changes made to the classes used on headings throughout Moodle.
217 This was done as per the Moodle HTML guidelines. h1 and h2 elements should have no classes, h3 and lower headings
218 may have descriptive classes only (any classes must properly describe the relation between the header and its content).
699e2fd0 219* The parameters value for the following functions have been modified: core_renderer::heading() and core_renderer::heading_with_help().
3b42864d 220 This means that headings using the default options will no longer have the class "main" which was the previous default.
d61c96b6 221* The file picker and activity chooser have been converted to use M.core.dialogue. This means the styles
222 for these elements have changed in the base and bootstrapbase themes and you will need to copy the new styles
223 if you are not inheriting from either one of these themes.
b4c6b42e 224* For the themes based on bootstrapbase please also read theme/bootstrapbase/upgrade.txt
225* A new component action_menu is now used to display editing icons for courses and blocks within a drop down. If you have a theme that doesn't
226 extend base, canvas, or clean then you will need to style for this new component within your theme.
227* The maintenance layout now has a special renderer that extends the core_renderer in order to prevent some methods from interacting
228 with the database. Please be aware that for the maintenance layout some methods now always return an empty string.
229 This has been done because it is important that during maintenance routines we don't show any links, interact with the database,
230 or interact with caches as doing so may lead to errors,
231 Please see the maintenance renderer notes below for details on the functions affected.
233Renderer changes:
234* core_course_renderer::course_section_cm_edit_actions has two new optional arguments and now uses and action_menu component.
235* core_course_renderer::course_section_cm has been altered to call core_course_renderer::course_section_cm_edit_actions with the two new arguments.
236* core_renderer::block_controls has a new optional argument (the block id) and has been altered to use the new action_menu component.
237* core_renderer::block_header has been altered to give core_renderer::block_controls the new second argument, the block id.
238* core_renderer::action_link has a new argument, and optional icon that can be rendererd into the link.
faf6010b 240Selector changes:
241* Changes to the classes given to the header produced when rendering a single section within a course.
242 .section-navigation.header.headingblock => .section-navigation.navigationtitle
243* Changes to the classes used when producing the course information box that lists courses.
244 The name (h3|div} of both courses and categories used to have .name, for courses in the list this was changed to .coursename and for categories in the list this was changed to .categoryname.
245* Classes ".header and .headingblock" were removed from all front page content headings.
246* Classes ".headingblock .header .tag-header" were removed from the tag index page
248Maintenance renderer notes:
249When the maintenance layout is being used $OUTPUT will be an instance of core_renderer_maintenance.
250This renderer mimics the core_renderer except that the following functions always return an empty string.
cf9f5a17 251* core_renderer_maintenance::block
252* core_renderer_maintenance::blocks
253* core_renderer_maintenance::blocks_for_regions
254* core_renderer_maintenance::course_header
255* core_renderer_maintenance::course_footer
256* core_renderer_maintenance::course_content_header
257* core_renderer_maintenance::course_content_footer
258* core_renderer_maintenance::custom_menu
259* core_renderer_maintenance::file_picker
260* core_renderer_maintenance::htmllize_file_tree
261* core_renderer_maintenance::lang_menu
262* core_renderer_maintenance::login_info
263* core_renderer_maintenance::user_picture
265If you have overridden methods of the core_renderer in your theme and want those changes to be shown during times of maintenance you
266will also need to override the core_renderer_maintenance and copy your customisations from the core_renderer to that.
90160639 268=== 2.5.1 ===
271* Block drag and drop functionality has been improved so that it works regardless of what block regions you use
272 or how many block regions you have. In order to benefit from this improvement you must convert your calls from
273 $OUTPUT->blocks_for_region() to $OUTPUT->blocks.
275Optional changes:
276* Theme config can nominate block regions to swap if the user is using a rtl languages such as Hebrew.
277 $THEME->blockrtlmanipulations should be an associative array, the key is the original block region, and the
278 value should be where the blocks in that region should be displayed.
279* New $OUTPUT methods to replace code that was previously using $PAGE. Converting to these methods is optional
280 but highly recommended. Refer to the bootstrapbase layouts for examples.
281 - $OUTPUT->body_attributes() returns a string you can use for the body id and classes.
282 - $OUTPUT->blocks() returns HTML to display a block region and all of its blocks. This adds data attributes
283 that ensure drag and drop of blocks will work no matter what block regions or how many you have.
284 - $OUTPUT->page_heading() returns the page heading. Replaces $PAGE->heading.
285 - $OUTPUT->page_heading_button() returns the button to display with the heading. Replaces $page->button.
286 - $OUTPUT->page_doc_link() returns the link to moodle docs for the page. Replaces page_doc_link().
287 - $OUTPUT->page_heading_menu() returns the heading menu for the page. Replaces $PAGE->headingmenu.
288 - $OUTPUT->page_title() Returns the title to use for the head section.
289 - $OUTPUT->favicon() returns the URL to the favicon.
291Renderer changes:
292* core_renderer::navbar now returns an empty string if there are no navigation items to display.
293* core_renderer::custom_menu now adds a class "custom_menu" to the div that contains the HTML for the custom menu.
295=== 2.5 ===
297required changes:
298* Functions core_course_renderer::course_category_tree() and course_category_tree_category()
299 are deprecated
300* Significant changes in rendering of courses and categories listings, lots of CSS classes changed,
301 several functions such as print_courses(), print_whole_category_list(), print_category_info()
302 are moved to course renderer.
303 See http://docs.moodle.org/dev/Courses_lists_upgrade_to_2.5
305DOM changes:
306* changed the h1 title in the help popup to a h2.
97dbc8f2 307* new setting $THEME->yuicssmodules = array('cssreset', 'cssfonts', 'cssgrids', 'cssbase'); which
12cb45f1 308 allows themes to use different CSS reset normalisers such as cssnormalize YUI module.
6e5d002e 309* Re-wrote the user profile views to definition lists.
310* Re-wrote the table for the course completion status block to use html_table - added some CSS classes to
311 the table in the process (see MDL-35608).
5581c618 312* Cancel buttons have the class btn-cancel.
313* Added a z-index for the div#dateselector-calendar-panel so that the calendar pop-up renders above
314 the filemanager when they overlap, ie. the course settings page (see MDL-39047).
315* Trivial change of CSS selectors used to display plugin status at the plugins overview
316 screen (#plugins-control-panel).

346* new layout option "nologinlinks" and new page layout "secure" e.g. for safebrowser and securewindow (MDL-31365)
bb128107 347* new class 'iconlarge' for 24x24 icons.
348* new icons i/export and i/import (sized 16x16). Previously export and import actions used i/backup and i/restore.
349* new icon i/assignroles (sized 16x16), to prevent the use of i/roles which is 12x12.
350* new icon i/switchrole (sized 16x16), was previously using i/roles. Now is a copy of the new i/assignroles icon.
351* new icons i/enrolusers and t/enrolusers, previsouly i/users was used.

c22fbd38 362* new classes 'icon-pre' and 'icon-post' supposedly to be used when the icon is positioned before or after the text. This is not really used yet, but it's a start towards some standardisation of the icon selectors.
363* new icons i/valid, i/caution and i/invalid for generic statuses.
364* new icons i/grade_correct, i/grade_partiallycorrect and i/grade_incorrect for grades.
851d3b7a 365* new icon t/approve (12x12).
