Fixed previous data showing after searching for a new class

Class statistics

• Fixed an issue where, after searching for a new class, some old data was mistakenly used instead of the correct new data

Internal

• Teacher leaderboard data will now be calculated if it's missing from Redis. This will only happen in the development environment
• Improved logging in the backend

Updates to graduation times and credit statistics accuracy

Study programme overview

• Graduation times (both median and detailed breakdown) for each study track can now be viewed in the Studytracks and class statistics tab. This information is accessible by clicking on any bar in the chart.

Class statistics

• Credit statistics section
  • The chart legend in the Distribution development tab has been clarified. Previously, the categories were displayed as "150–180", which caused confusion. Now, they are presented as "150 ≤ credits < 180" for greater clarity.
  • Filters in the Credits gained tab have been corrected. The filters now properly reflect the number of credits earned by students during a specific period. Previously, the filter incorrectly used the Credits earned filter from the left sidebar, which included all credits regardless of when they were earned.
  • The Personal study plan filter is now applied correctly in the credit statistics. When this filter is active, only the credits included in the student's study plan are shown in the table.

Internal

• Sentry has been upgraded from v6 to v8 in the frontend.

Course statistics: Details on Students tab removed

Course statistics

• Details (Passed on first attempt, Passed eventually) were deleted from the Students tab

Course statistics: Filter out courses constructed of custom attainments

Course statistics

• Due to a big change how custom attainments are handled, course search became partly unusable because of the large number of custom codes, most of which are not relevant at all. These courses have now been filtered out to make the course search more usable

Study guidance group view optimized

Study guidance groups

• In the previous version, the study guidance group page either did not open or was very slow. The page has now been optimized, and the loading time should be much shorter.

Class statistics

• In the previous version, the Total page, which shows the combined statistics of all students in a study programme, did not display any students. This issue has now been fixed.
