Editing EPrints 3.4.3 (section)

==== Bug Fixes ====
* Prevents access code from changing if request a copy is approved multiple times (and warns if request has already been approved).
* Fixes bug with logged in users not being able to access approved request a copy documents that they would not normally have access.
* Fixes formatting of results from user search introduced by accessibility changes in 3.4.2.
* Updates issue citation to use <code>&lt;div&gt;</code> rather than <code><tr></code> and <code><td></code> 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 <code>EPrints::List</code>.
* 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 <code>SameSite</code> property to <code>None</code> 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 history tab rather than an internal server error for the whole page.
* Allows use of same pin multiple times within a phrase.
* Prevents undefined <code>$c->{aliases}</code> from causing <code>epadmin config_core</code> to fail.
* Ensures saved searches indicate email notifications cannot be sent when the <code>Xapianv2</code> (in addition to <code>Xapian</code>) plug-in has been used for the original search.
* Adds missing <code>event_queue</code> phrases.
* Fixes inappropriate mapping of <code>monograph_type</code> 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 <code>readonly</code> attribute works for <code>MetaField::Set</code> in compound-multiple fields.
* Adds missing <code>reason</code> phrase for <code>RejectWithEmail</code> screen plug-in.
* Prevents HEAD requests (e.g. email link checkers) for password from resets from actioning the reset.  (Otherwise, when the user clicks the link it will say the password has already been reset, which may concern the user).
* Forces full day-month-year to be set for document embargo expiry to avoid any ambiguity.
* Improves <code>epadmin</code> by removing unusable functionality and reporting if database tables do not get created as expected.
* Adds symlinks between <code>brief</code> and <code>default</code> citations for various data objects to prevent log warnings.
* Better handles DOI not being set when parsing it.
* Provides more useful logging when field has invalid parameters.
* Fixes missing pin for error message phrase when restarting indexer.
* Fixes <code>MetaField::Listing</code> from logging an error that no <code>datasetid</code> is defined when on its index page (listing datasets).
* Updates positions for plug-ins that appear in key tools menu to ensure deterministic ordering.
* Fixes bug to allow REST calls for subjects with IDs that contain full stops (.).
* Better handles finding parent eprint when this has been deleted.
* Fixes <code>tools/map_config.pl</code> to use correct directory for EPrints 3.4 and allow flavour to be specified as a parameter.
* Fixes <code>tools/update_phrase/file</code> to ensure EPrints libraries can be used and allows specified base path, current working directory or full path to be used for phrase file parameters.
* Fixes BibTeX import using uploaded files broken by update to third-party <code>BibTeX::Parser</code> in EPrints 3.4.2.
* Fixes RDF export by adding doi namespace for when id_number field is set to a DOI and is then translated to an owl:sameAs in a RDF export.
* Fixes bug preventing exporting file data objects in various metadata formats (e.g. Atom, EP3XML, CSV, etc.).
