/*******************
 * 2.0 Build 19
 * 2009-07-06
 *********/
 * Fixed bug; There was a possibility of SQL injection in the submitters account
   update form. This SQL injection bug could not lead to any unauthorized access
   to data or unauthorized data modification.
 * Fixed bug; There was a possibility of SQL injection in the import variant and
   patient data form by using specially crafted import files. This SQL injection
   bug could not lead to any unauthorized access to data or unauthorized data
   modification.
 * Added a check for the MIME-type of the imported data file.
 * Added a table with the number of variants per exon to the summary tables.
 * When authorized users submit new data, they are forwarded back to the patient
   in question.
 * DBID values ending in _00000 are now always allowed and are not verified.
 * To prevent common sorting problems,  the variant sort code has been  extended
   to also contain the padded exon value.
 * Added the name(s) of the curator(s) to the top of the page, to increase their
   visability.
 * LOVD will now throw a warning if an invalid gene database name has been given
   instead of ignoring it.
 * Fixed bug; When editing a variant belonging to more than one patient,  values
   from multiple-selection lists were not properly stored in the database if the
   "Edit variant only for this patient" option was selected.
 * Fixed bug; The update checker did not work in if the allow_url_fopen setting
   was disabled. The update checker can now use fsockopen() as a fallback.
   (thanks to Sandro Garoffolo, Università degli Studi, Torino, IT, for testing)
 * Updated the location of the GeneTests database to the new URL at the NCBI.
   (thanks to Donna Maglott, NCBI, USA, for reporting)

 * Added two new custom column types: decimal input and date input fields.
 * Fixed a few wrong lovd_showSID() calls which could lead to session logouts.
 * Fixed bug; Even when cookies were disabled, they were mandatory to log in.
 * Fixed bug; The variant sort code did not always sort variants after the  stop
   codon correctly.
 * Fixed bug; The AJAX database URL check did not work from the install form.

   each line, and could therefore not handle columns with large selection lists.
 * Fixed bug; Implemented better fix for multiple-selection lists on the patient
   origin based variant overview.
 * Implemented a quick way to switch gene databases, regardless of on which page
   you are;  just click the "switch gene database" icon next to the gene name on
   the top of the page.
 * Fixed bug; When changing a gene's GenBank file, LOVD did not correctly reload
   the Mutalyzer module.
 * Fixed bug; Sometimes LOVD warned falsely that an exact duplicate of a variant
   entry already existed in the database.
 * When a submitter edits a patient or variant entry, LOVD now checks whether or
   not any of the fields have been changed. If nothing has been changed, nothing
   is updated.
   (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)
 * Added "Copy column" advanced edit feature,  to copy or move one column's data
   into another column.
 * Fixed bug; When using Find & Replace or Copy column on either the Variant/DNA
   or Variant/Exon columns, the variant sort code was not updated.
 * When searching through the variant listings,  links to the Find & Replace and
   Copy Column scripts are provided for authorized users.
 * Included version 2.7 of official LOVD Reference Sequence Parser script.
   - The gene for which you want to create a reference sequence file, can now be
     picked from a drop down list.
   - Fixed bug; In some cases a notice was generated and the  genomic  numbering
     was reset.
   - Fixed bug; The number of nucleotides was not displayed correctly when there
     was an exon/intron boundary in first line of the coding sequence.
   - Fixed bug; The numbers of the exons were missing zeros in the first line of

   databases could time out after 30 seconds.
 * Fixed bug; When curators agreed to changes performed by a submitter, the data
   was not prepared correctly for the database, and in some cases an error could
   occur. This could also lead to an SQL injection problem.
   (thanks to Jorge Oliveira, Instituto Nacional de Saúde Portugal, for testing)

     table showed some errors and the links from the cDNA sequence were broken.
   - It will not automatically create a GenBank file,  if also the source of the
     sequence was a GenBank file.
   - If gene information other than the currently gene selected was given, that
     information was reset every step.

 * 2008-09-26
 *********/
 * The session cookie is now really deleted when logging out of LOVD.
 * The "loss of session" fix of the 2.0-11 update did not do the trick properly.

   which a user was logged out directly after logging in. Implemented a fix that
   gives unique names to session cookies.
   **** Please NOTE that this fix causes all active users to be logged out! ****
 * Public submitter listing reported the total number of submitter accounts, not
   only the active accounts.
 * Added increased execution time to import script to help import bigger files.

 * In new installs, the Patient/Origin/Ethnic column can hold 50 chars, in stead
   of 25.
 * Changed "Start data type wizard" button on two custom column forms so that it
   no longer has preference over the submit button when pressing enter.
 * Added LOVD custom column "Variant/DNA_published".
 * Which columns are hidden from view is now stored in a separate cookie so that
   it will be remembered across sessions.
 * Added 'hide column' feature to two other variant listings; variant listing on
   patient origin and submitter variant listing.
 * When assigning a GenBank file to a gene, LOVD will now check if it's there or
   not.
 * Reloading modules was not possible due to "cannot redeclare class" errors.
 * When a gene has been created and has an uploaded GenBank file, or when a gene
   has been edited and an uploaded GenBank file has been added or  changed,  the
   mutalyzer module is reloaded automatically.
 * Prevent some troubles with the menu when the URL contains double slashes.
 * Modified CURRDB->buildSearchList() to accept field type.
 * Added new feature that allows the public to find the amount of entries in the
   database (including hidden entries) matching one or more search terms.  It is
   turned off by default.
 * Added update of Reference Sequence parser script, which was also available in
   LOVD 1.1.0. Added the ability to work from a GenBank file.
 * Included the LOVD manual of September 26th, 2008.


/*******************
 * 2.0 Build 11 (update)

 * Fixed missing image in release (gfx/header_docs.png).
 * Fixed links in header that are broken in the documentation section.
 * Fixed typo in empty gene form.
 * Fixed security hole; implemented XSS protection on search forms. Search terms
   could be manipulated to include malicious javascript code into the page.
 * Fixed bug; Find & replace did not select current gene by default.
 * Fixed bug; Find & replace malfunctioned which resulted in data loss when  the
   find field contained a / (forward slash).
   (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)
 * Fixed bug; If find & replace malfunctions, it no longer results in data loss;
   instead it returns an error requesting the user to file a bug.
 * Fixed bug; Find & replace did not find matching records when "Field value is"
   match was performed using a find value that included _ or %.
 * Fixed bug; Find & replace now skips updates if the new value would not fit in
   the column and warns the user afterwards.
   (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)

   code. Implemented function throughout LOVD.
 * Added check on $_GET['gene'] and $_POST['gene'] on submission form to prevent
   fatal errors with SQL injection or XSS attacks through these variables.
 * Added XSS check on the $_GET['order'] var of all sortable overviews. This has
   never been a security problem, but it prevents some harmless errors.
 * Added check against entering newlines in user and submitter names, preventing
   the insertion of additional mail headers in registration and submit emails.
 * Fixed bug #18 for downloaded files as well (see changelog for 2.0-beta-10).
 * Fixed bug; email addresses containing an one-letter subdomain were rejected.
   (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)

 * Fixed bug; If deleting a gene database, LOVD possibly showed the wrong number
   of variants that will be lost by deleting the gene.
 * Deleting a user makes the current user curator of the deleted user's genes if
   there is no curator left for them.
 * A user can no longer be deleted through the edit form.
 * Curators exporting variant data in central repository format will now only be
   able to select their own genes, preventing possible "Access denied" errors in
   the output format.
 * When deleting a variant, LOVD did not display the correct allele information.

   (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)
 * Modified manager's genes overview to build the link to the gene homepage only
   when a URL is filled in.
 * Fixed bug; LOVD didn't show managers correctly whether or not a  gene  had  a
   GenBank record associated with it.
 * Fixed bug; LOVD may have checked the wrong gene for DBID verification in case
   a value was filled in by a curator during variant submission.
 * Fixed bug; LOVD did not predict matching DBID values correctly, if it was not
   in the format of GENESYMBOL_[five digit number].


/*******************

   value if the DBID value was not the highest used value increased by one.
   Implemented #26; "Cannot use DBID out of sequence".
 * Fixed bug; If two separate DBID values were assigned to the same DNA variant,
   the user was forced to have the variant use the lowest DBID value, even if it
   was shared with a different variant.
   Fixed bug #27; "Incorrect DB-ID can often not be fixed".
 * Reduced seconds of waiting time in the installation script that took the load
   off the server a little bit by giving it a break now and then. Also, Internet
   Explorer users never see the progression of the installation so the long wait
   looking at an empty screen also gets less annoying.
 * Added central repository download format. This format includes the gene name,
   DNA change, DB ID, and possible OMIM and DbSNP IDs.
 * Fixed bug; Default pathogenicity code of imported variants was pathogenic  in
   stead of unknown pathogenicity.
 * Fixed bug; Links from the Configuration area to the selected gene's uncurated
   variants did not show the "Non public" variants because of a change in search
   term processing in LOVD 2.0-05.
 * Updated LOVD status page to split gene symbol and name to separate fields.
 * Added LOVD custom column "Variant/Remarks".
 * Editing patients by submitters doesn't mark all it's public variants anymore,
   and curators can now agree to the submitter's changes by a single click.

   (thanks to Ammar Husami, Cincinnati Children's MC, USA, for reporting)
 * Simplified the URL to link to PubMed a bit.
   Implemented #25; "Simplified PubMed link".
 * Fixed bug; Import script did not recognize version header if it was quoted.
 * Included new pathogenicity codes from 2.0-04 in the variant legends also.
 * Updated variant counts on the gene homepage to use the Patient/Times_Reported
   column if it's available. Added patient count.
 * Updated LOVD status page to include Patient/Times_Reported counts as well and
   put results in tabular format.
 * Implemented check on Patient/Times_Reported also on statistics sent upstream.
 * Implemented new ability for submitters to update previous submissions if  "My
   Submissions" is enabled.
 * Fixed bug; Wordwrapping in notification emails didn't always work properly.
 * Added consistency check on Variant/DBID field. This will make sure that equal
   DBID values are assigned to equal variants. Also, the Variant/DBID field will
   be filled in automatically if left empty.
 * Allowed more space for column headers, they can now be 30 characters long.
 * Included version 0.2 of official LOVD module "showmaxdbid".
   - Fixed bug; If during submission a gene was selected other than the  current
     gene database, the wrong DBID was given on the form.
     Fixed bug #23; "Showmaxdbid displays wrong gene".
     (thanks to Raymond Dalgleish, University of Leicester, UK, for reporting)

 * Added Free Edit feature which was present in 1.1.0 also - ability to find and
   replace values in a specific column throughout one or more gene databases.
 * Translated Dutch code comments to English.
 * Updated the code that checks for empty form elements to prevent possible  PHP
   notices.
 * Added warning message on the edit variant form of variant entries  which  are
   shared with other patients, that changes apply to all patients.
 * Updated the variant overviews, if more than 10 other variants are  associated
   with the same patient, they are hidden to provide a cleaner overview.
 * Full submitter information is now directly accessible from the submitter link
   in the Patient/Reference column.  Email addresses have been removed from  the
   submitter public listing.
 * Fixed bug; LOVD installation title was mentioned to have a default value, but
   an empty field was not allowed. Leaving the field empty will now set the LOVD
   installation title to the mentioned default value.
 * Got rid of "undefined" value in Patient ID field showing in Internet Explorer
   browsers in the "Using an existing patient" popup on the submission form.
 * Shortened some long standard page refresh times.


/*******************
 * 2.0 Build 04

 * Installation instructions are now in INSTALL.txt in stead of INSTALL  because
   the case insensitive filesystem on Windows hosts does not allow  the  INSTALL
   file to co-exist next to the install directory.
 * Fixed bug; Variant overview based on patient origin showed in some cases some
   form markup problems. Also shortened the listed gene names to make more space
   in the form.
 * Included the variant listing based on patient origin in the Variants menu.
 * Fixed bug; It was possible to assign a patient to a deleted submitter.
 * Improved the variant listings per submitter -  you can now select which genes
   you want to see the variants of.
 * Added a link in the Variants menu for switching to another gene database.
 * Fixed memory consumption problem of import script occuring in large databases
   when loading all variant and patient2variant data into the memory. This fixes
   the problem in most cases, but memory errors can still occur depending on the
   server settings.
   Added warning on the import page about this.
   Fixed bug #17; "Impossible to import anything anymore,  import script returns
   empty page".
 * When resetting a custom column to the system defaults, you are forwarded back
   to the column information directly.
 * Fixed bug; Custom column data type information was quoted twice, which mostly
   effected the regular expression patterns, resulting in rejected form input.
   NOTE: Regular expression patterns already effected by this bug are not fixed.
 * Fixed bug; When navigating from the setup's submitter overview to the variant
   listing, not all genes where searched in.
 * Added ability to permanently remove submitters which do not have any patients
   in the system.
 * When editing a configured custom column, the width of the column is displayed
   just below the column width field, to give an idea of the current situation.
 * Fixed bug; When visiting two LOVD installations after each other,  LOVD could
   report an error about a non-existing gene.

 * Fixed bug; The LOVD updates information, retrieved from the LOVD website, was
   not quoted but put in the database directly in the case of an available  LOVD
   update. This resulted in a silent query error for the 2.0-03 update.
 * Fixed bug; Downloading variants may not download the homozygous mutations!!!
 * Enabled LOVD to run under the Secure Socket Layer HTTP (HTTPS) protocol.
 * Added ability to select if LOVD should run under SSL (HTTPS) only.
 * Improved efficiency by having a block of code skipped when just checking  for
   updates.
 * Fixed bug; Alternative link from submitter's variant listing to detailed view
   did not work.
 * Replaced 'polymorphism' with 'variant with no known pathogenicity', according
   to HGVS recommendations.
 * Updated pathogenicity list to be able to include more pathogenicity values in
   the future. All existing entries will be updated by the upgrade script.
 * Added options "Probably pathogenic" and "Probably no pathogenicity".
 * Added format version number in the variant download file. This allows LOVD to
   apply corrections when importing older file formats. When importing a variant
   download file from 2.0-04 into an older LOVD release, remove the first line.
 * Fixed bug; If a custom link was active for a column which was not added, lots
   of error messages appeared on the submission form.
 * Dropped upgrade support from the alpha releases.  If you are running an alpha
   release (from before April 27th,  2007) you need to upgrade to a beta release
   first, before you can upgrade to the latest stable release.
 * Included version 0.2 of official LOVD module "mutalyzer".
   - Added module to the variant edit form.
   - Fixed bug; intronic mutations containing a plus were not sent to  Mutalyzer

   a search field.
   Fixed bug #21; "Cannot search on submitter ID".
 * Added lovd_magicQuoteAll() and lovd_magicUnquoteAll() functions and  modified
   existing lovd_magicQuote(&$var) and lovd_magicUnquote(&$var) functions to get
   rid of deprication errors in the error log when using PHP 5.X.
 * Modified lovd_magicQuote() function to use mysql_real_escape_string() instead
   of addslashes(). Carriage returns and linefeeds are not affected.
 * HGVS standard columns can now be edited (Managers and up).
 * Searching for a specific non-public variant by unauthorized users now results
   in a specific check is such a variant exists, and a proper message to contact
   the curator.
 * Non public variants can now be excluded from the unique variant listings (see
   "Security settings" section of the LOVD system settings).
 * Fixed some grammatical errors.
 * When you edit non-global column settings you are no longer required to  enter
   your password.
 * Fixed problems when editing the system settings because the disease list  can
   get rejected because of too strict pattern matching on this page.

/*******************
 * 2.0 Beta 10
 * 2007-10-19
 *********/
 * Fixed some markup errors in emails sent by LOVD.
 * Changed default sorting column from Exon to Variant/DNA.
 * Fixed bug; when sorting on the DNA column, the variants were not sorted based
   on the sort algorithm; a simple text sort was used in stead.
   Fixed bug #18; "Variants do not sort correctly when selecting DNA  column  to
   sort on".
 * Implemented new lovd_wrapText() that handles long words (text without spaces)
   more intelligently.
 * Added ability to set whether a custom column is 'standard' or not; this is of
   use for Variant columns only as newly created genes will include all standard
   Variant columns.
 * Moved some duplicated JavaScript code for sorting custom columns into an  own
   include file.
 * Updated regular expression that checks selection list options and added  this
   check to the forms managing Variant and Patient columns.

 * Changed variant listing query a bit that fetches other mutations in the shown
   patient, to fix somewhat buggy behaviour in the display of the variant names.
 * Applied a few changes to clearify the view for computers with a smaller sized
   screen (setup area, submit area).
 * Added option to add a variant to the submission process,  which is already in
   the database. The functionality used to support the user choosing the desired
   variant makes use of the AutoComplete library by Richard Heyes (phpguru.org).
 * Fixed bug; the setup area showed the wrong date the system was last updated.
   Fixed bug #15;  "Date updated shows date of installation,  not date  of  last
   update".

 * View patient information without considering any variants is now possible.
 * Empty values (no value previously selected from the list) are no longer added
   to selection lists on edit forms.
 * After editing a patient's data, the user is now forwarded back to the patient
   information page in stead of the gene's general variant listing.
   Fixed bug #13; "Edit patient redirect leads to listing of all contents".
 * Fixed bug; when viewing a variant with unknown allele in detail, all variants
   from the same gene in the same patient where highlighted in the listing.

   'ID_pathogenic_', 'ID_status_', 'ID_submitterid_',  'ID_variant_created_by_',
   'ID_variant_edited_by_', 'ID_patient_created_by_', 'ID_patient_edited_by_'.
 * It is no longer needed to repeat variant or patient information in the import
   file; as long as the 'ID_allele_', 'ID_variantid_' and 'ID_patientid_' fields
   are present, all other fields can be left empty for previously known entries.
 * If a selection list is converted to a text field, a note is added that values
   should be separated by a semi-colon (;).
 * Fixed bug; if a selection list had previously been converted to a text field,
   but now selection options have been provided, the previously chosen value was
   lost if it was not part of the new list of options.
 * LOVD will now throw an error when there is no MySQL support installed instead
   of showing an empty page.
 * When selecting a different gene database, you do not need to click the button
   anymore.


/*******************
 * 2.0 Beta 05
 * 2007-07-06
 *********/
 * Updated LOVD module system; modules are now allowed to edit LOVD forms.
 * Included version 0.1 of official LOVD module "mutalyzer".
 * Fixed bug; while selection list fields where converted to text fields in  the
   absence of a valid set of selection list values,  the previously chosen value
   was not converted to a text value.

   because some Windows computers could not interpret the value.  The format has
   been changed to LOVD_GENESYMBOL_YYYY-MM-DD_HH.mm.ss.txt.
 * Fixed bug; multiple-select option lists do not send their data when no option
   has been selected. This caused an error message in LOVD.
 * Added search overview based on patient origin.  This overview can search  for
   variants in all genes in the LOVD installation that match your patient origin
   search terms.
 * Increased size of three standard columns, as they were too short by accident;
   Variant/DNA, Variant/RNA and Variant/Protein.  All existing databases will be
   updated by the upgrade script.
 * The small blue light icons that were used to show whether an option was on or
   off, have been replaced on some pages by marks (V or X) to improve clearity.
 * When defining the selection list values of a custom column, the question mark
   (?) is now accepted as a valid abbreviation value.
 * Sorted the values of the exon numbers selection list on the search form.
 * Added "My submissions";  a feature which allows submitters to get an overview
   of all submissions they've sent to the database. It also allows others to get
   the list of submissions for any submitter. This feature can be turned off, so
   that it is only accessible for authorized users (Curators and up).
 * Added "Update your registration" link to the manage user overview when a user
   is viewing his own account.
 * Changed wording on configuration area and setup area a bit to clearify custom
   column features.
 * At install time, LOVD will also check for modules.


/*******************
 * 2.0 Beta 04

   activated for the gene reference field on the gene homepage.
 * Log events can now span 15 characters.
 * LOVD columns 'variant_edited_date_' and 'patient_edited_date_' are no  longer
   mandatory during import.
 * The standard LOVD column 'ID_sort_' is no longer mandatory to be included  in
   the import file, and it's value will be automatically generated when empty.
 * Fixed bug; a database error was shown under certain conditions when importing
   new entries whilst already having entries in other gene databases.
 * The import form now shows the available variant and patient IDs to facilitate
   easy import of new variants or patients.
 * The standard LOVD columns 'variant_created_date_' and 'patient_created_date_'

   will be automatically generated when empty.
 * Removed redundant menu options for the configuration area if there is no gene
   database created yet.
 * Downloading entries from an empty gene database by curators now yields a file
   containing the column headers, instead of a "no variants" message.
 * When using cookies for user authentication, the cookie path is now set to the
   LOVD install path, if set to '/'.  This increases security by not sharing the
   PHP session ID with other websites on the same server and allows working with
   several LOVD instances on one server at the same time.
 * Fixed bug; lovd_calculateVersion() did not handle 2.0-XXX-00X type of version
   style.
 * Fixed bug; MySQL error message was not shown in the case of errors during the
   import of variants in InnoDB table types.

   is not applicable to LOVD 2.0.
 * Added password quality check, to increase overall security.
 * Fixed typo in full legend description of the Variant/RNA column.
 * Dropped upgrade support from the development releases.  If you are running  a

   an alpha release first, before you can upgrade to the latest beta release.


/*******************
 * 2.0 Beta 01
 * 2007-04-27
 *********/
 * Added default value to "Times reported" column on submission form.
 * Added ability for managers and curators to edit the selection list values  of
   custom columns.
 * Dropped error reporting feature. It will not be implemented in LOVD 2.0-01 so
   all related settings have been removed from the config.ini file.

   of the custom links.
 * Fixed bug; when editing a variant, the sorting code was not updated.
 * Added LOVD custom column "Patient/Times_reported", which is added by default.
 * Fixed bug; CURRDB->checkInputType() reported wrong value for the column name,
   and did an invalid check for the integer type, which always returned false.


/*******************

 * Fixed bug; variant allele value was not properly mentioned in the  submission
   email.
 * Changed the standard system log sorting direction to newest to oldest.
 * The Patient/Phenotype/Disease column is no longer mandatory so that  patients
   without noticably affected phenotypes can be added to the system.
