Provisional Release Notes

New Dependencies

None as yet. Check earlier dependencies for EPrints 3.4.2 and before.


Changes Since 3.4.2

New Functionality

  • Provides function (EPrints::Utils::compare_version) for comparing EPrints software versions so plugins can choose to behave differently.
  • Adds jquery EPrints 3.4 ingredient to allow JQuery resources to be incorporated if required by non-core EPrints functionality. Ingredient added but commented out in flavours/pub_lib/inc.
  • Provides picker for date fields to reduce potential for human error.


Security and Privacy Improvements

  • Makes JSON export respect value set for export_as_xml to avoid exporting unintended fields.
  • Sets contact_email to not export by default for better GDPR compliance.
  • Rate limits failed local login attempts for a particular user. Defaults to 10 failed login attempts in 10 minutes (using $c->{max_login_attempts} and $c->{lockout_minutes} configuration options).
  • Rate limits new account requests. Defaults to 100 requests in a hour long period to avoid causing problems with planned mass sign up events. Configured using $c->{max_account_requests} and $c->{max_account_requests_minutes} options.
  • Limits the maximum length of a password (default 200 characters) to prevent specific Denial-of-Service attacks.
  • Modifies latex invocation to make more secure an ensure it rights to the correct output directory.
  • Removes legacy /cgi/latex2png script to prevent Remote Code Execution (RCE) from CVE-2021-3342.
  • Validates parameters passed to /cgi/cal script to protect against RCE and Cross Site Scripting (XSS) from CVE-2021-26475 and CVE-2021-26476.
  • Validates dataset parameter passed to /cgi/dataset_dictionary to protect against XSS from CVE-2021-26702.
  • Validates parameters passed to /cgi/history_search to protect against the possibility of XSS and MySQL injection vulnerabilities, although none currently exploitable.
  • Validates verb passed to /cgi/toolbox/toolbox to protect against RCE from CVE-2021-26704.
  • Allows EPrints::XML::parse_string to temporarily modify parser configuration to disable expanding of XML entities by the /cgi/ajax/phrase script to protect against 2021-26703.
  • Ensure eprints_lang cookie explicitly sets SameSite attribute to Lax if HTTPS is not enabled or sets secure attribute to 1 if it is.


General Improvements

  • Resolves all accessibility errors and most alerts (as reported by the WAVE Web Accessibility Evaluation Tool) for backend admin pages as listed in the Accessibility report.
  • Appropriately uses protocol-relative, preferred (i.e. https where available) or absolute path URLs instead of http URLs to avoid mixed content warnings and other similar issues.
  • Uses HTML class for Longtext_counter counter line and provides CSS to by default make this red and bold if the maxwords limit is exceeded.
  • Allows full path or just subject name to be displayed for values set in subjects field by setting render_path attribute (true by default).
  • Allows time between password reset requests to be configured (to a number of hours) rather than hard-coded to 24 hours.
  • Adds option to set status of EPrints that should be checked by check_xapian script.
  • Adds date_embargo_retained field to Documents to retain the embargo date after the embargo is lifted.
  • Adds deprecation warning to indicate only LibXML library will be supported in future versions of EPrints. (Version for removal yet to be confirmed).
  • Adds basic default citation for files.
  • Adds validation for date fields to prevent invalid dates being set.
  • Allows files to be stored to disk with generic filenames (i.e. <fileid>.bin) rather than the upload filename that can cause retrieval problem by setting the $c->{generic_filenames} configuration setting.
  • Adds code to lib and pub_lib versions of security.pl to deal with request a copy access issue if repository has coversheets plugin enabled.
  • Allows sub-fields to have help texts configured.
  • Generates log message for views that have reached their max_items limit.
  • Allows document fields displayed in an eprint's Details tab to be configured.
  • Adds data-context attributes to aid CSS styling of HTML div elements within search forms.
  • Improves scaling of of Lightbox popups on narrow screens.
  • Allows a pin to set the id or class attribute for a template HTML element to facilitate different CSS styling on different pages.
  • Prompts for organisation name when creating a new archive using epadmin create.
  • Allows classes to be assigned to parts (i.e. top, left, main, after, etc.) of abstract/summary pages to facilitate better CSS styling.
  • Allows search results forms to be configured to automatically reload on ordering change.
  • Allows classes for EPrints' user menu (i.e. by default ep_tm_key_tools) to be configured to better integrate with institutional branding.
  • Adds commented advice on fixing issues with PDF thumbnail generation using ImageMagick.
  • Tidies up citations by removing identical flavours/pub_lib/ citations that appear in lib/.
  • Allows max_files that can be expanded from an uploaded zip file to be configured. (Previously hardcoded to 100 file limit).
  • Allows customisable overriding of type-mapping based on ispublished value for BiBTeX and RIS export. (I.e. not using @unpublished type if ispublished set to unpub).


Bug Fixes

  • Prevents access code from changing if request a copy is approved multiple times (and warns if request has already been approved).
  • Fixes formatting of results from user search introduced by accessibility changes in 3.4.2.
  • Updates issue citation to use <div> rather than and tags so it works with accessibility changes introduced in 3.4.2.
  • Deals more gracefully if History DataObj's parent does not exist when checking if it is an EPrints::List.
  • Fixes internal server error when trying to save values to a non-multiple compound field.
  • Fixes issue with XML import setting unset compound subfields to NULL rather than empty string.
  • Fixes errors on import pages caused by Accessibility improvements and fixes other Accessibility issues for import pages.
  • Fixes broken link of default 401 error page.
  • Sets STDOUT and STDERR binmode to utf8 to avoid wide character errors.
  • Fixes user history layout as a result of earlier Accessibility improvements.
  • Fixes missing phrases reported in error logs. Typically fieldhelp phrases for sub-fields of compound fields, which are generally not rendered but still report missing phrase warnings.
  • Sets SameSite property to None for secure login and request copy cookies as Google Chrome is now quite strict about this.
  • Provides handling for XML parsing of revision files to show warning for particular revision in the hostory tab rather than an internal server error for the whole page.
  • Allows use of same pin multiple times within a phrase.
  • Prevents undefined $c->{aliases} from causing epadmin config_core to fail.
  • Ensures saved searches indicate email notifications cannot be sent when the Xapianv2 (in addition to Xapian) plugin has been used for the original search.
  • Adds missing event_queue phrases.
  • Fixes inappropriate mapping of monograph_type in BibTeX import.
  • Fixes erroneous post-login redirection when login required to access eprint summary/abstract pages and long URLs (e.g. /id/eprint/1234) enabled.
  • Ensures readonly attribute works for MetaField::Set in compound-multiple fields.
  • Adds missing reason phrase for RejectWithEmail screen plugin.
