V4 update specific notes

General update considerations

We always aim to ensure continuity of users ability to use MEMORY with all updates. We strive to release every update with miniminal alteration to current user's usage.

Algorithm Update

Existing users should read the document to see the updates to the algorithm in V4
Read about the algorithm update

Please remember: If you go back to the old version, any features such as rich-content question cards won't be visible in the original version. Creating a course on the new version with the new features (e.g. manual mode or rich questions) won't be visible to other users and may have unexpected effects.

OVERVIEW OF FEATURES

Introductory guided tour for the create course screen
Improved course export now exports multi line questions easier, and includes both images and custom audio
You can how add rich content cards to levels - dress up your course and give users an introduction to your course. Level content is accessible during learn mode.
Design your flashcards and questions: Questions and answers can now have rich text and images added to them
Select your questions during learning mode
Add stars or remove stars during learning to add questions to saved sets
Go back a question whilst learning
Retry a question whilst learning - NOTE: Retrying still considers the previous answer as incorrect
MEMORY is now available in Spanish with other languages to come. Selecting a language does not affect your courses.
New bulk import: Use an interactive Excel-like spreadsheet to add questions (optionally switch back to textual input)
One by one view: Edit questions one by one without loading the entire level (useful for courses with lots of questions per level). If you load questions with 200+ questions per level, you may often experience screen lag. This functionality covers that.
Drag and drop questions to reorder them in card view
Print PDF now works in many more languages - with supporting fonts
Filter questions whilst you edit
You can now shuffle all questions in user settings - to reset the 'due now' time to 'now'. Doing so does not affect history, but it allows you to reconfigure your intervals according to spaced repetition learning algorithm adjustments.

FIXES

Fixed course password entry on course dashboard screen saying you are not logged in as the correct user (fix is retrospectively applied in v3)
Flashcard preview mode now respects course creator's question ordering
User's default question creation order is preserved throughout the site, e.g. Print PDF (in correct order, or Select Questions to study)
We removed automatic capitalization of multiple choice questions - by popular request

LEARNING ALGORITHM - SPACED REPETITION FLASHCARDS

Listening mode: For same language courses, this now acts as a spelling test instead of typing the answer, you type what you hear
Speaking mode now functions as a "say what you hear" mode for same-language courses
Listening mode now has a higher chance of being typing mode instead of multiple choice
NEW: Manual mode: Select exactly how you wish your questions to be served, which order, which question type, answer type and languages
Question types are now smarter - based on your answer history for a question, we use a more sophisticated formula to detect which type of question to serve in smart mode
- Higher guarantee of question types returning a better type in smart, custom and manual modes - using new weighted random algorithm

PERFORMANCE - STUFF FOR GEEKS

Less waiting: High XP users should no longer noticeably slow down when doing things such as completing sessions and viewing graphs.
Improved in-learning speed: no more janky flashcards, smoother experience
Less bandwidth - faster page loads and automatic optimised images
Faster page loading on card view mode
Server side rendering - the site is now rendered initially by a server to improve response times
The Skeleton bandwagon - out with the 'ajax spinners', in with the Facebook style Skeletons whilst components are loading
Less javascript - faster page loads from code splitting
