v1.1.10 - 2019-09-21

GitHub Release Page

Fixed

Page change detection has been updated to include addition checks which allow for the current lack of the active tab class being applied to the learn tab. This is expected to be added back by duolingo so the current detection methods using class name changes on the learn tab.

v1.1.9 - 2019-09-08

GitHub Release Page

Changed

Modified how the name element of each skill is selected to be more general. It now is defined as the first (and likely only) element with the class name defined in SKILL_NAME that is a child of each element with class name defined in SKILL_CONTAINER. Similarly the icon element is selected by class name, not its relative relation to the container element.

Fixed

Fixed display suggestion to correctly try again after a wait if the page hasn't loaded fully yet.

v1.1.8 - 2019-09-06

GitHub Release Page

Fixed

Added check to see if skills have two container elements, and uses the inner most container.
XP prediction is now fully separate from the XP breakdown and updates correctly.

v1.1.7 - 2019-09-03

GitHub Release Page

Changed

Crowns prediction is now considers the number of lessons left at the time of calculation instead of the last count used in caluclating the rate. This makes the prediction more accurate when the daily goal has yet to be met.
Strength bars are now aligned with the skill above them, and the strength value is inside the bar itself.

v1.1.6 - 2019-08-16

GitHub Release Page

Fixed

Detection and definition of element at the top of the skill tree after a change in class name between in beta trees and fully developed trees.
Added handling of new container element around each skill.

Changed

Replaced all uses of duolingo class name strings with constants.

v1.1.5 - 2019-08-07

GitHub Release Page

Added

Detection of mobile layout, where the device or window width is smaller than 700px wide.
Handling of the mobile layout to all relevant functions.
Detection and handling of moving between mobile and desktop layouts.

Fixed

Handling of needs strengthening lists with just one skill. The preceding & is no longer added.

v1.1.4 - 2019-08-06

GitHub Release Page

Fixed

Definition of the username from the url of the profile tab. Now makes sure to just use the text after the last /.

Added

Handling of the new TRY PLUS button at the top of the skill tree. Any information displayed at the top of the tree now has its width limited so that it doens't overlap with the button.

v1.1.3 - 2019-08-01

GitHub Release Page

Added

Added support for users that have had the Daily Goal box moved from the streak pop-up box to the side bar.

Changed

Applied hide zeros rows options to bonus skill rows in crowns breakdown.

v1.1.2 - 2019-07-31

GitHub Release Page

Added

Option to show or hide rows in the crowns breakdown, that have no skills at that level.

Changed

Added detection for IN BETA label at the top of beta trees so that the needs strengthening list or skill suggestion will be shown below this now.
Options are now initially set to defauls and overwritten by the stored values. This allows any new options to be set to on first use, then saved in storage.

v1.1.1 - 2019-07-30

GitHub Release Page

Changed

Method for calculating current rate of XP gain reworked to count whole days, the method also only includes XP gained today if the goal has been met.
Tweaked calendar method for calculating days to next crown level to only include any progress from today if the goal has been met.

Removed

Old UI (blue top navigation bar) detection and handling. It is assumed that all users have been changed to the new UI (white top naviagtion bar), so no users should be affected.

v1.1.0 - 2019-07-29

GitHub Release Page

Added

This CHANGELOG.

Crowns info

Additional crowns information for the current tree to the crowns pop-up menu or crowns side box depending on the UI version.

Display of total XP earned for the current language.
Display of language level for the current language.

Skill suggestions

Displays a, by default, random skill of the lowest crown level as a practice suggestion if the tree is completed and fully strengthened.
Displays the next skill to be learnt on incomplete, fully strengthened trees.
Focus is set on skill suggestion so that on exiting a lesson, return can be hit to take you into practicing the suggested skill.
The method for selecting the suggested skill can be customised on the options page.

Options page

Options page which is accessible via the right click context menu of the Duo Strength logo or via the extensions details.
Ability to enable or disable every feature and feature component.
Ability to customise the behaviour of some features.
Enable and disable all buttons.

Changed

Updated README screenshots and text to include new features.

Needs Strengthening List

Now shows, by default, 10 skills that need strengthening instead of every skill.
Additional skills can be displayed by clicking show more. This adds another, by default, 10 skills.
The number shown can be customised on the options page.
The order in which the list is sorted can be customised on the options page.

Strength Bars

Non 100% strength bars now show in grey the width of a full strength bar to make more clear the progress that can be made for that skill.
These backgrounds can be toggled on the options page.

Depreciated

Support of old UI version with the blue top navigation bar is being removed. All users should have been moved to the new UI version with the white navigation bar. Handling of the old UI will be removed in v1.1.1 to simplify the code.

v1.0.22 - 2019-07-18

GitHub Release Page

Changed

Fixed detection of if there exists the topBarDiv and thus if we are in a lesson or not. This is in response to duolingo's removal of comment nodes in the tree.
Fixed styling of strength bars where the width of the holder had matched the length of the title of the skill.
Detection of bonus skill section of the tree updated to match new structure where the section is now marked by being sandwiched between two divs containing an hr rather than the row having a different class.
Renamed dataReactRoot to rootChild as the data-react attribute has been removed from the element.
username is now set by the end of the href of the profile tab button, rather than from the href of the achievement link. This allows the username to be set when the achievement box is not there, e.g. when in mobile layout.

v1.0.21 - 2019-06-26

GitHub Release Page

Changed

Fixed language changing issue as described in issue #14.
language is now set using the requested data rather than from the page itself.
The number of active requests is now kept track of to help handle multiple language changes done in quick succession.
Fixed handling of language change from pages other than the main page.

v1.0.20 - 2019-06-20

GitHub Release Page

Changed

Fixed issue on Firefox where the the data only loaded when first logging in to duolingo, as found in issue #13. Data requests are now executed in the context of the document rather than the extension.

v1.0.19 - 2019-06-17

GitHub Release Page

Changed

Fixed handling of moving in and out of lessons. Follows on from v1.0.18 in updating an index that made incorrect after an update from duolingo.

Removed

Unnecessary duplicate requests in a few locations. Should be about half the amount of requests now.

v1.0.18 - 2019-06-11

GitHub Release Page

Changed

Fixed topBarDiv definition. It is now found and defined by its className rather than its childNodes relation to dataReactRoot.

v1.0.17 - 2019-05-22

GitHub Release Page

Changed

Replaced every instance of progress_3 with skill_progress, as duolingo has changed the key with which they store the crown level for each skill.

v1.0.16 - 2019-05-15

GitHub Release Page

Changed

Child node index used to select topBarDiv adjusted following addition of a new comment node above it.
Check for location of main body element changed to check if it is in 4th place following addition of new comment node above it.

v1.0.15 - 2019-05-04

GitHub Release Page

Changed

Fixed typo of append(...) to appendChild(...) when adding strengthenBox as found in issue #12.

Removed

Unnecessary and incorrect margin-top of shopButtonFloatedDiv.

v1.0.14 - 2019-04-28

GitHub Release Page

Added

Handling of the new white UI version to all functions affected.
Use of the new UI handling only when oldUI is false, and the old procedure when it is true.

Changed

Repurposed checkUIVersion from checking if using the 'juicy' UI (which is now assumed) to checking if the white UI version is in use. This now sets the oldUI flag instead of juicyUI.
Moved the removal of the old strength bars and strengthening list to earlier in the change language process. This stops any old data from showing up on the new tree.

Removed

shopButtonFloatedDiv when using the new white UI, as there is no longer a shop button at the top of the tree. Note it is still added when using the old UI.
Output to console used in debugging that was left in the last release.

v1.0.13 - 2019-04-24

GitHub Release Page

Changed

Reworked the way we request the user data to help with handling language changes, especially quick successive language changes that happen while we were waiting for the new data.
checkUIVersion now makes sure that we are on the main page before checking if the three is using the new juicy UI assets.

Removed

Global numBonusSkillsInTree value as it was only used when displaying the strengthening list and the value was passed into the function anyway.

v1.0.12 - 2019-04-15

GitHub Release Page

Removed

Display of 0 crown, i.e. unfinished, skills from the needs strengthening list.
Strength bars from 0 crown, i.e. unfinished, skills.

The changes are in response to an update to the Spanish from English tree, where new skills were added in the middle of the tree. These new skills had varying strengths depending on overlap with on skills, causing skills which had not been started, let alone finished, to display as needing strengthening.

v1.0.11 - 2019-04-08

GitHub Release Page

Added

Updated GOLD and RED colours to match 'juicy' UI look.

Changed

checkUIVersion to check for the new 'juicy' UI version by checking the src of the crown assets. This now sets the juicyUI flag instead of the newUIVersion flag.
Made text flow around shop button in the needs strengthening list.

v1.0.10 - 2019-03-19

GitHub Release Page

Added

Updated Login screen detection so that an error isn't thrown and the extension runs on first login without needing a refresh.

Changed

Fixed URL used to request the user data which caused issues in Firefox.

v1.0.9 - 2019-03-15

GitHub Release Page

Added

Handling of switches to and from the words page on language that have it.
Wait and retry when displaying the needs strengthening list if the tree hasn't loaded yet, say after a page change.
Tracking of if we are on the main page or not. This lets us stop the display processes if we switch away from the tree mid way through.

Changed

Fixed the location that the needs strengthening list is displayed on tree which had Part 1, Part 2 etc. headings, which duolingo has now removed.
Fixed processing of tree to include selection of locked skills.

v1.0.8 - 2019-03-15

GitHub Release Page

Changed

Fixed bug described in issue #4 which caused the strength bars not to update if they had already been displayed.

v1.0.7 - 2019-03-12

GitHub Release Page

Changed

Replaced every instance of progress_1 with progress_v3, as duolingo has changed the key with which they store the crown level for each skill.

v1.0.6 - 2019-03-01

GitHub Release Page

Changed

Changed how the name element, where the strength bar for each skill is inserted, is selected to fix issue #3. This is due to duolingo restructuring how the elements in each skill are laid out, which caused the extension not to display.

v1.0.5 - 2019-02-26

GitHub Release Page

Added

Firefox store info to the README.

Changed

Converted HTMLCollection to Array for increased compatibility. See issue #2 for details.

v1.0.4 - 2019-01-16

GitHub Release Page

v1.0.2 - 2019-01-10

GitHub Release Page

Changed

Skills that have yet to be started are no longer added to the needs strengthening list. These skills have a 0 strength value, as opposed to the normal minimum strength of 25% for a skill that has been started.

Removed

Unused tab permission which was causing a message to appear on install saying that the extension could read the user's browser history.

v1.0.1 - 2019-01-09

GitHub Release Page

Added

Chrome store link to README
Screenshots to README
Detection of new UI version used for some languages. This new duolingo UI splits the tree into different parts, headed Part 1, Part 2 etc. and adds pentagonal checkpoint nodes at the end of each part.

v1.0.0 - 2019-01-08
