Editing EPrints 3.4.3 (section)

==== General Improvements ====
* Resolves all accessibility errors and most alerts (as reported by the [https://wave.webaim.org/ WAVE Web Accessibility Evaluation Tool]) for backend admin pages as listed in the [https://accessibility.eprints-hosting.org/accessibility/report.html Accessibility report].
* [[#Configuration for URLs and Paths|Tidies up the use of configuration URLs and Paths]]
* Uses HTML class for <tt>Longtext_counter</tt> counter line and provides CSS to by default make this red and bold if the <tt>maxwords</tt> limit is exceeded.
* Allows full path or just subject name to be displayed for values set in subjects field by setting <tt>render_path</tt> 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 <tt>check_xapian</tt> script.
* Adds <tt>date_embargo_retained</tt> 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. <code><fileid>.bin</code>) rather than the upload filename that can cause retrieval problem by setting the <code>$c->{generic_filenames}</code> configuration setting.
* Adds code to <code>lib</code> and <code>pub_lib</code> versions of <code>security.pl</code> to deal with request a copy access issue if repository has coversheets plug-in enabled.
* Allows sub-fields to have help texts configured.
* Generates log message for views that have reached their <code>max_items</code> limit.
* Allows document fields displayed in an eprint's details tab to be configured.
* Adds data-context attributes to aid CSS styling of HTML <code>&lt;div&gt;</code> elements within search forms.
* Improves scaling of of Lightbox popups on narrow screens.
* [[Using Page ID in Templates|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 <code>epadmin create</code>.
* 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 <code>ep_tm_key_tools</code>) 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 <code>flavours/pub_lib/</code> citations that appear in <code>lib/</code>.
* Allows <code>max_files</code> 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 <code>ispublished</code> value for BibTeX and RIS export. (I.e. not using <code>unpublished</code> type if <code>ispublished</code> set to <code>unpub</code>).
* Provides <code>has_role</code> EPC function to allow more granular control of workflows that can be edited by specific group of user that have has this role added to their profile.
* Allows positioning of hovering document preview to be set to left or right and implements this in <code>summary_page</code> and <code>result</code> eprint citations to improve preview positioning.
* Improves verbosity of <code>get_input</code> and <code>get_input_hidden</code> to explain better why input is invalid.  Assisting <code>epadmin</code> data entry.
* Makes <code>id_number</code> (i.e. for DOIs, etc.) field default type <code>id</code> rather than <code>text</code> to facilitate search for exact IDs, especially those containing non-alphanumeric characters (e.g. 10.1016/j.ejor.2018.02.047).
* Restricts characters that can be used in new user-added subject IDs to alphanumeric characters, underscores and hyphens.
* Ensures subject-type field behaves the same in default (i.e. multiple select form element) as it does in subject tree format.  I.e. subject tree mode lets previously selected subjects stay selected, even if the subject itself has been set as undepositable  in the intervening period.  Default mode silently unselects these.
* Switches to using real ''bazaar'' ingredient rather than ''bazaar_stub'' for zero flavour in <code>EPrints::SystemSettings</code> as this former is now available in core codebase.
* Prevents removing items that have and have once been in the live archive, without an extra permission: <code>eprints/remove_once_archived</code>.  (Retiring items is still permitted without extra permission).
