# Changelog
This change log tracks the releases on our [pilot server ](https://recodex.mff.cuni.cz/ ). Since ReCodEx is in fact composed of many components, we also provide a table of component version which work together in stable releases.

## 29.4.2018
* Introducing data-only exercises (the user submits only data which are validated by custom judge).
* Improving Smart-Fill feature in test configuration form.
* Gravatar optimizations -- user may disable/enable own gravatar and configure whether gravatars are visible to hir in general
* Results table in Group Detail page is sortable by name and by total points now.
* User may delete own submission comments.
* Performance optimization of various SQL queries, functions, and visualization.
* Displaying judge logs to supervisors.
* Additional API preparations (to be implemented in UI yet)
- Do not allow to create exercises without assigned group
- Introduce mass list endpoints for users and exercises
- Add endpoint for downloading best solutions archive of an assignment
## 20.4.2018
* Various bugfixes and optimizations in REST API
## 17.4.2018
* Switching to Font Awesome 5 icons
* Bug fixes, forgotten UI issues
## 14.4.2018
* Implementing support for organizational groups (organizational groups are meant for creating hierarchy, they cannot hold students nor assignments).
* Adding language/environments list to assignments and exercises.
* Exercise marked as broken on creation and if appropriate on forking
* Create a submission failure when the submission will not even compile
* Add revocation mechanism to authentication tokens and invalidation endpoint for all issued tokens of user (API only)
* Implement issuing of restricted read-only tokens for usage in applications or scripts (API only)
* Deadline of created assignments is further in the future and not now
* Implement endpoint for deletion of comments (API only)
* Refactoring, optimizations, bug fixes
## 28.3.2018
* Group page redesign - splitted into two pages (info and detail), cleaner design and much better performance
* Assignments can restrict the set of runtime environments (as a subset of the RTEs of the exercise)
* Pre-submit files validation with automated environment selection and entry point (bootstrap file) selection
* Entry point selection also added to extra files in the exercise config form
* Completed Czech translations
* Bug fixes and performance optimizations
## 4.3.2018
* Form for assigning exercise in multiple groups at once was debugged and enabled.
* External accounts (accounts mapped to SIS accounts) are prevented from changing their names.
* Supervisors may delete solutions submitted by the students.
## 26.2.2018
* Fixing bugs.
## 25.2.2018
* Test limits were redesigned
- Move to a separate page in the UI
- Changed internally in the API (simple limits endpoints were removed)
* Hardware group selection was added to the limits page
- Second hardware group for long-running exercises added
- Limits constraints are now bound to selected hardware group
* Students can see stats table when enabled in group settings
* Many bugs were fixed; number of submitted solutions reflects correct state (#153)
## 15.2.2018
* CPU/wall time selection in limits form (called "precise time measurement" in UI)
* Extra (additional) files for exercise compilation can be provided by exercise author
* Solution source codes and exercise test files can be downloaded as single ZIP package
* New page for managing SIS interaction (for admins)
* Students who also teach now can see both courses (which they study and which they teach) in SIS mappings
* Exercise configuration is tested when edited and possible errors are reported
* Group tree view improved and filtered, so only groups visible to logged user are shown
* Bug fixes and performance optimizations
## 16.1.2018
* Users registered externally are now able to create local account
* Several modifications in API and default pipelines, which are not apparent from webapp yet:
- All compilation pipelines supports extra source files given by exercise author (so custom frameworks or boilerplates may be used in exercises)
- Added cpu-time alongside wall-time in exercise limits and submission evaluation
* Multiple bugs fixed and minor improvements implemented in the web application frontend
* Refactoring and consolidation of some parts of the frontend in preparation for the modifications of the API
## 3.1.2018
* Added comment statistics to assignment solution list view
* **Pascal** solutions will now accept multiple files
* Added new file/folder existance check after compilation of user solutions (useful for cases when a compiler like **FPC** does not output proper binary file even if told to)
* New loading screen to make sure the javascript bundle is loaded before anything else happens
* Allow proper caching of bundle and static content in browser, which should bring better performance
* Updated **CAS** login process, which should help especially on Android and (possibly desktop) Firefox to handle both authentication phases correctly
* Display point stats in students assignment overview component
* Multirow comment texts at solutions
* Added custom messages for **Pascal** exit codes
## 19.12.2017
* Proper synchronization of assignments which copies all needed items
* Various UX impromevents
