New Version 2.9.1 Released

This is primarily a bug fix release.
It is recommended to update 2.9.0 installations to 2.9.1.

Changes from 2.9.0

Student interface
    - Course catalog: display of subcategory names containing spaces
      works again.
    - Browser detection updated for IE for consistency in charset used
      for rendering symbols with TeX-to-HTML (TTH).
    - Remove HTML tags and decode HTML Entities in message excerpt
      sent as e-mail, (unless user preference set to retain HTML tags),
      and encode in utf8 before sending.
    - Ability to post to discussion based on "discussend" parameter
      takes precedence over the ability to post based on problem's open
      status for student.


Instructor interface
    - Description for roles-based and user-based course-wide blocking of
      discussion or chat no longer reversed in course settings interface.
    - Resource-specific parameter for discussend setting (closes discussion)
      applies to standalone boards (i.e., those not associated with homework).

      resource, if user has author/co-author privileges for resource.
    - Restriction of a slot to use with specific resource now works correctly.
    - Speed-up in processing enrollment of users from an uploaded CSV file.
    - Leading and trailing spaces trimmed from email, domain,
      institutional status and username entries from uploaded CSV file.
    - Reverse association for columns in file of users works again.
    - Improvements in feedback when enrolling from CSV file if institutional
      rules for format of usernames and/or studentIDs prevent user creation.
    - Names of users affected by bulk access date changes made with
      "Manage Users" utility displayed correctly.
    - Automated adds and automated drops settings stored correctly for
      course requests.
    - Display when changing parameters in table mode rendered correctly.
    - Course Coordinator can now use the role switcher to change to a role
      in cases where the user's own assigned roles include an expired role
      of the same type/section in the course.
    - If user has advanced role (and hence discussion is always open),
      note appended to discussion link, if discussion is closed for
      other roles.


Authoring resources
    - Publication of raw XML files (i.e., with .xml extension) allowed again.
    - Warning that alt-tag is still output, even for encrypted URLs;
    - Can assign a co-author role to a username containing an underscore.
    - Updates to problem templates (Custom Response, and plot data) to:
      (respectively) extend recognized number types, and limit execution time.


Printout generation:
    - TeX errors eliminated when printing .sequence files with answers
      (or only answers) from Construction Space.
    - TeX errors eliminated when printing HTML tables created dynamically
      within a script block.
    - Table border settings now enforced when printing tables.
    - Text in table cells with align="right" attribute kept vertically aligned.
    - Support restored for the TeXwidth attribute in <td> tags.
    - TeX errors eliminated when generating printouts with answers only,
      or in a composite page.
    - Printing of folders containing simplepage(s) works again.


Domain Coordination
    - Domain Coordinator can override course-specific cloning rights.
    - Selection of clonable courses based on wildcard within a specific domain
      possible again.

      original role context is preserved.
    - Display of roles in hot list for Domain Coordinator readability restored.
    - Auto-creation of courses via command line call with arguments
      (legacy method) works again.
    - Domain Coordinators can filter courses by creation time when selecting
      a course.
    - Warning displayed if clone selection is attempted when no course
      owner specified.
    - Domain Coordinator can display cloning information in course
      creation requests.


Internals/system behavior
    - Changes to reduce the incidence of timeouts when large amounts
      of data are sent between LON-CAPA machines across the network.
    - Frequency/times for new entries being added to lonapa cron now saved
      by ./UPDATE
    - Improvements to filtering for Community roles when assembling roles
      supported on LON-CAPA version installed on server hosting user's session.
    - Scientific Linux version checking for updates to RPMs works again.
