UniTime 4.6 Release Notes 4.6.99 Fri, 16 Dec 2022 Manage Solvers: Solver Allocated Memory Added ability to disable computation of allocated memory of each solver instance (by setting unitime.solvers.memory to false). Roll Forward Session: Building and Room Data, Teaching Requests Fixed the following two errors caused by PostgreSQL being less lenient when it comes to query parameter types than MySQL or Oracle. Roll Building and Room Data Forward From Session: operator does not exist: boolean = integer Roll Forward Teaching Request For Subject Areas: operator does not exist: bigint = character varying Edit Academic Session: Bugfix Ensure that the academic session is not updated when the page is reloaded due to a date change. 4.6.96 Tue, 28 Jun 2022 Instructional Offering Detail: Wait-Listing Always show that the offering is wait-listed when wait-listing is set differently on the offering from what is set by default (unitime.offering.waitListDefault is true) or the offering allows for wait-listing. So, when the default is true and it is not changed on the offering, show that the offering is being wait-listed. This allows to always check and show wait-listing problems (e.g., course is wait-listed and allows for closed section overrides at the same time). Course Finder: Courses with matching campus first When subject area starts with the student's campus code, move courses that match student's primary campus to the top of the list. This is disabled by default, enable by setting unitime.enrollment.listOfferings.campusFirst to true. Student Scheduling Dashboards: Enrollments Corrected display of the number of not-assigned no-sub course requests. Edit Course Offering: Permissions for External Managers It is now possible to give external managers some control over the offering. When unitime.permissions.courseOfferingAllowExternalEdits is true (defaults to false): EditCourseOfferingCoordinators: passes when the external manager can edit at least one of the classes (ManagerLimitedEdit) EditCourseOfferingNote: passes when the external manager can edit at least one of the classes (ManagerLimitedEdit) EditCourseOffering: passes for the controlling course when the external manager can edit all the classes (ManagerEdit) It now also possible for the external managers to edit reservations if all the classes are in their control (ReservationOffering permission). Instructor Availability Corrected combination of unavailable dates and blocking events (when unitime.events.instructorUnavailability is set to true). This fixes an issue where unavailable dates were ignored when instructor unavailability events were enabled. Distribution Type: Max N Consecutive Days Added a distribution constraint that limits the number of consecutive days that can be taught each week. Individual weeks are considered when FlexibleConstraint.CheckWeeks is set to true. Distribution Type: Max N Days, Max N Half-Days Added ability to evaluate the Max N Days and Max N Half-Days constraints separately for each week. When FlexibleConstraint.CheckWeeks is set to true, defaults to false. Distribution Type: Same Days-Room-Start Given classes must start at the same time of day, on the same days and in the same room. It is the combination of Same Days, Same Start and Same Room distribution preferences. When prohibited or (strongly) discouraged: Any pair of classes classes cannot be taught on the same days during the same time in the same room. Spread Constraint Fixed an ArrayIndexOutOfBoundsException thrown when there are 7 working days (i.e., all days of the week are working days). Timetable Grid: Export XLS Avoid exporting empty resources (resources with no matching classes/meetings). This is to fix NullPointerException in per-date mode, e.g., if there is an instructor with no classes. Reporting: Room Utilization Report Helpers Added code that can be called from scripts to generate room utilization and occupancy reports. Currently these only work with the Oracle database. The data generated by the reports can be broken down by room or building. Within a room, it can also be further subdivided by the department and/or subject area teaching the classes using the room. Within a building the data can be be further subdivided by the room type, department and/or subject area teaching the classes using the room. Example utilization reports are available in the Documentation/Scripts. Name Format: Include External ID Added ability to include external id in the name format. The following options are not available: ext-last-first-middle ext-first-middle-last ext-last-first-middle-title ext-title-first-middle-last ext-title-initial-last ext-title-last-initial To make (some of) them available, added them as options in Administration > Defaults > User Settings, name parameter. 4.6.82 Mon, 28 Feb 2022 Data Exchange: Course Offering XML Import Fixed parsing of boolean values in some of the imports (including Course Offering XML import). Data Exchange: Event XML Load Added an ability to specify the current academic session on the root element (year and term attributes). Course elements for course-related events do not need year and term specified separately in this case. Lookup for the rooms in the current/default academic session first, only look for the rooms in all sessions when no matching room is found in the current/default session. People Lookup: Source Mapping Corrected source mapping when unitime.lookup.source.defaults property is used. 4.6.77 Wed, 29 Jan 2022 Configuration Only certain courses may be enabled for wait-listing (there is a toggle on the Edit Course Offering page). By default, only selected courses can be wait-listed. This can be changed using unitime.offering.waitListDefault which defaults to false. Certain overrides can be disabled for wait-listed courses (using unitime.offering.waitList.prohibitedOverride). For example, a student should not be allowed to request a class limit override for a course that can be wait-listed. There is now a different toggle for wait-listing (Wait-List) and for just indicating that a course cannot be substituted (No-Subs). A student (Course Requests, Scheduling Assistant) can use one or the other, based on the student status. An advisor (Course Recommendations) can use one or the other, based on the unitime.acr.waitlist setting (defaults to None) or based on the student status. Student Scheduling Assistant An additional information about wait-listed courses is displayed, in the Wait-Listed Courses section (shown when at least one course is wait-listed). As only some course can be wait-listed, the Wait-List checkbox is only available if the first-choice course can be wait-listed. There is a warning when a wait-listed course overlaps with the rest of the schedule. Student Scheduling Dashboard Wait-List and No-Sub toggles are separated, including the Filter / assignment. A course only shows as wait-listed while the student is allowed to wait-list and the course can be wait-listed. Show wait-listed courses in the detail of a student, and additional wait-list information (like the wait-listed time stamp, or student's position on the wait-list) on various places of the page. Various improvements in the filtering for wait-listed courses. Custom Validation A custom validation of the wait-listed course requests can be implemented using the WaitListValidationProvider class. The validation does work similarly to pre-registration, using a test schedule, but doing one course at a time on top of the existing schedule. It may include max credit overrides. Process Changes Re-scheduling is disabled by default (students are not moved around during course unlock). Can be enabled by setting solver configuration parameter Enrollment.ReSchedulingEnabled to true. Students wait-listed for a course are processed in the following order: Course request priority (critical courses) first, student priority second, wait-listed time stamp last. Students with a pending override, a time conflict, or students over max credit are skipped. The order can be customized (e.g., only be based on the wait-listed time stamp) Email notifications added when custom enrollment fails (it is not possible to enroll student because of registration error). Wait-list toggle is no longer automatically enabled when a student attempts to enroll to a course that is currently locked. Various improvements across all the wait-listing functionality. Special Registration: Variable Title Workflow Added an ability to plug-in a variable title course request workflow. This include a new functionality on the Scheduling Assistant page and an API that can be used to create a variable title course in UniTime. Course Requests: Requested Credit Requested credit computation updated to consider students (and optionally) advisor's no-subs/wait-listed courses. A no-sub/wait-listed course cannot be replaced by a substitute course. The advisor recommendations are only considered when the solver parameter Load.UseAdvisorWaitLists is set to true. Online Student Scheduling Dashboard: Requested Approvals Details of a student: show student's requested approvals in a new tab when available. Batch Student Scheduling: Section Times Added ability to load arranged hours (no time) classes with a time (listing the date pattern but no time) and rooms (that are required by the class). This allows the effective date pattern and required room to show on arranged hours classes on the solver dashboard. Can be disabled by setting the solver parameter Load.ArrangedHoursPlacements to false (defaults to true). Student Scheduling Dashboards: Enrollments When showing classes of a course, list all classes (but the classes that do not match the filter are grayed out). It is possible to switch between showing all classes and just the matching classes using the sctdashShowUnmatchedClasses user setting parameter (defaults to yes, show unmatched classes). Student Scheduling Dashboards: Additional Filter Capabilities Requested credit range (e.g., requested-credit:>=15 for students that requested 15+ credit hours) First-choice credit range (e.g., first-choice-credit:>=15 for students with their first-choice requested courses of 15 or more credit hours) Choice / alternativity (e.g., choice:>1 for cases where an alternative course is assigned, or not-assigned primary course request has at least one alternative) Request Priority (e.g., rp:<=2 for course requests that are of priority 1 or 2) Online / Face-to-face / Has-Time / No-Time (e.g., face-to-face:<2 for students with less than two face-to-face classes, or online:>50% for students with more than half of their classes online) Added ability to filter by primary academic area, classification, major, concentration, or program (e.g., primary-area:A) Student Program Added ability to include an optional program field on a student, with academic area, major, and classification. Included in Student XML and Course Requests XML exports and imports. Student Scheduling Dashboards: Added optional Program column and the ability to filter by program. Student Campus Added ability to include an optional program field on a student, with academic area, major, and classification. Included in Student XML and Course Requests XML exports and imports. Student Scheduling Dashboards: Added optional Campus column and the ability to filter by program. Course Finder Sections that the student cannot be enrolled in are grayed out even when there is space in them. Hide sections and instructional methods not allowed by the Online-Only filter. Added a column listing whether the course is wait-listed and/or has some allowed overrides. Banner XE API Added ability define whether advisors using the XE API will set or not set the admin flag (systemIn parameter). Examination PDF Reports Added new output format options: CSV, XLS, and PDF using a non-monospaced font. Solver: Stop Added ability to stop the solver after it has finished, while running the when finished actions, including: solution save (all solvers), student sectioning (course timetabling solver), validation (student scheduling solver). Roll Forward Session Roll date pattern preferences (for alternative date patterns) forward. Corrected rolling forward of learning community reservations (special case of student group reservation). Added ability to roll forward wait-listing (is an offering wait-listed) and prohibited overrides. Added Support for JDK 16+ Various dependencies updated to avoid illegal access exceptions. MemoryCounter updated to avoid illegal access calls (using the Unsafe access instead). LDAP authentication is disabled by default, to enable add the following line to catalina.properties: unitime.spring.context.security=securityContextLDAP.xml Added Support for Apache Tomcat 10 Due to the move from Java EE to Jakarta EE, the Tomcat 10 compatible version of UniTime is available under web-tomcat10 in the distribution.
