- avoid issues with having the same instructor listed two times on the same exam (under different departments)
  - was causing Null exception during solver unassignment

- do not allow for a date pattern & exact time combination that has no meetings

- fixed an array index out of bounds when generating the room availability thumbnail icons in some instances

- changed the script to work with UniTime 4.8 (individual hbm.xml files are no longer used/listed in the Hibernate config file)
- added IF EXISTS in the drop sequence command

- to reduce query logging, the following calls have been changed to be logged only when there is an exception
  IsSessionBusyRpcRequest
  ServerTimeZoneRequest
  MenuRpcRequest
  PageNameRpcRequest
  SessionInfoRpcRequest
  UserInfoRpcRequest
  VersionInfoRpcRequest
  GetQueueTableRpcRequest
  SolverLogPageRequest

- these are very quick calls with no or very little parameters called either on every single page, or periodically when a page is opened

- added some basic Eclipse settigns in an attempt to avoid thousands of errors and warnings when the project is opened in Eclipse

- on the Students tab, show student PINs for students that have their PIN released
- allow admins and/or advisors to release/suppress student PINs (Student Scheduling Can Release Pin permission needed)
- for students that do not have PIN filled in, added a custom interface for populating student PINs (unitime.custom.StudentPinsProvider property)

- added student PIN and PIN released flags in the student and course requests XML imports and exports

- Student XML: added pin and pinReleased attributes to the student element
  <student externalId="1002" firstName="Brian" lastName="Student" email="[email protected]" pin="FBA9D8" pinReleased="true">

- Requests XML: added pin element under updateDemographics with value and released attributes
  <updateDemographics>
    <name first="Brian" last="Student"/>
    <pin value="FBA9D8" released="false"/>
    ...
  </updateDemographics>

- added a simple custom PIN provider, returning the first 7 characters of the MD5 hash of the student's external id
- to enable, set
  unitime.custom.StudentPinsProvider=org.unitime.timetable.onlinesectioning.custom.test.MD5StudentPinProvider

- fixed API logging for pin-release action

- fixed the Maven compilation issue for the test MD5StudentPinProvider

- More menu: when both Release PIN and Suppress PIN operations are available, do not show a separator in between them

- MD5StudentPinProvider: use the first 6 digits of MD5-hashed student external id for the PIN

- lookup the sponsoring organization when a sponsoring organization is listed with a name or an email without UniTime's uniqueId
- for example:

{
  "eventName": "My Test Event",
  "eventType": "Special",
  "eventEmail": "[email protected]",
  "contact": {
    "externalId": "100"
  },
  "sponsor": {
    "name": "Test Org"
  },
  "meetings": [
    {
      "location": {
        "resourceName": "EDUC 102"
      },
      "meetingDate": "2010-09-14T00:00:00Z",
      "startSlot": 114,
      "endSlot": 126
    }
  ]
}

- added an option to make sponsoring organization a mandatory field for special events
- enabled by setting unitime.events.sponsoringOrgRequired to true (defaults to false)
- when set to true, sponsoring organization must be set when creating a new special event

- added an ability to customize the short name format which is used, e.g., in the Last Changes component
- can be changed using the unitime.managers.shortNameFormat property, defaults to initial-last
