1513 # improvements from SAN Ouest Provence :
1514 # * introducing a category_type into categories. It can be A (adult), C (children), P (Professionnal), I (institution/organisation).
1515 # * each category_type has it's own forms to create members.
1516 # * the borrowers table has been heavily modified (many fields changed), to get something more logic & readable
1517 # * reintroducing guarantor/guanrantee system that is now independant from hardcoded C/A for categories
1518 # * updating templates to fit template rules
1520 # (see mail feb, 17 on koha-devel "new features for borrowers" for more details)
1522 # Revision 1.133 2006/04/13 08:36:42 plg
1523 # new: function C4::Date::get_date_format_string_for_DHTMLcalendar based on
1524 # the system preference prefered date format.
1526 # improvement: book fund list and budget list screen redesigned. Filters on
1527 # each field. Columns are not sortable yet. Using DHTML Calendar to fill date
1528 # fields instead of manual filling. Pagination system. From the book fund
1529 # list, you can reach the budget list, filtered on a book fund, or not. A
1530 # budget can be added only from book fund list screen.
1532 # bug fixed: branchcode was missing in table aqbudget.
1534 # bug fixed: when setting a branchcode to a book fund, all associated budgets
1535 # move to this branchcode.
1537 # modification: when adding/modifying budget/fund, MySQL specific "REPLACE..."
1538 # statements replaced by standard SQL compliant statement.
1540 # bug fixed: when adding/modifying a budget, if the book fund is associated to
1541 # a branch, the branch selection is disabled and set to the book fund branch.

1553 # Contrib from Tümer Garip (from Turkey) :
1555 # in /tools/ the holiday.pl script let you define holidays (days where the library is closed), branch by branch. You can define 3 types of holidays :
1556 # - single day : only this day is closed
1557 # - repet weekly (like "sunday") : the day is holiday every week
1558 # - repet yearly (like "July, 4") : this day is closed every year.
1560 # You can also put exception :
1561 # - sunday is holiday, but "2006 March, 5th" the library will be open
1563 # The holidays are used for return date calculation : the return date is set to the next date where the library is open. A systempreference (useDaysMode) set ON (Calendar) or OFF (Normal) the calendar calculation.

1588 # utf8 is a : go for beta test in HEAD.
1589 # some explanations :
1590 # - updater/updatedatabase => will transform all tables in innoDB (not related to utf8, just to warn you) AND collate them in utf8 / utf8_general_ci. The SQL command is : ALTER TABLE tablename DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci.
1591 # - *-top.inc will show the pages in utf8
1592 # - THE HARD THING : for me, mysql-client and mysql-server were set up to communicate in iso8859-1, whatever the mysql collation ! Thus, pages were improperly shown, as datas were transmitted in iso8859-1 format ! After a full day of investigation, someone on usenet pointed "set NAMES 'utf8'" to explain that I wanted utf8. I could put this in my.cnf, but if I do that, ALL databases will "speak" in utf8, that's not what we want. Thus, I added a line in Context.pm : everytime a DB handle is opened, the communication is set to utf8.
1593 # - using marcxml field and no more the iso2709 raw marc biblioitems.marc field.
1595 # Revision 1.124 2005/10/27 12:09:05 tipaul
1596 # new features for serial module :
1597 # - the last 5 issues are now shown, and their status can be changed (but not reverted to "waited", as there can be only one "waited")
1598 # - the library can create a "distribution list". this paper contains a list of borrowers (selected from the borrower list, or manually entered), and print it for a given issue. once printed, the sheet can be put on the issue and distributed to every reader on the list (one by one).

1606 # Revision 1.122 2005/09/02 14:18:38 tipaul
1607 # new feature : image for itemtypes.
1609 # * run updater/updatedatabase to create imageurl field in itemtypes.
1610 # * go to Koha >> parameters >> itemtypes >> modify (or add) an itemtype. You will see around 20 nice images to choose between (thanks to owen). If you prefer your own image, you also can type a complete url (http://www.myserver.lib/path/to/my/image.gif)

1621 # this commit contains :
1622 # * updater/updatedatabase : get rid with marc_* tables, but DON'T remove them. As a lot of things uses them, it would not be a good idea for instance to drop them. If you really want to play, you can rename them to test head without them but being still able to reintroduce them...
1623 # * Biblio.pm : modify MARCgetbiblio to find the raw marc record in biblioitems.marc field, not from marc_subfield_table, modify MARCfindframeworkcode to find frameworkcode in biblio.frameworkcode, modify some other subs to use biblio.biblionumber & get rid of bibid.
1624 # * other files : get rid of bibid and use biblionumber instead.
1627 # * does not do anything on zebra yet.
1628 # * if you rename marc_subfield_table, you can't search anymore.
1629 # * you can view a biblio & bibliodetails, go to MARC editor, but NOT save any modif.
1630 # * don't try to add a biblio, it would add data poorly... (don't try to delete either, it may work, but that would be a surprise ;-) )
1632 # IMPORTANT NOTE : you need MARC::XML package (http://search.cpan.org/~esummers/MARC-XML-0.7/lib/MARC/File/XML.pm), that requires a recent version of MARC::Record
1633 # Updatedatabase stores the iso2709 data in biblioitems.marc field & an xml version in biblioitems.marcxml Not sure we will keep it when releasing the stable version, but I think it's a good idea to have something readable in sql, at least for development stage.

1645 # Letters / alert system, continuing...
1647 # * adding a package Letters.pm, that manages Letters & alerts.
1648 # * adding feature : it's now possible to define a "letter" for any subscription created. If a letter is defined, users in OPAC can put an alert on the subscription. When an issue is marked "arrived", all users in the alert will recieve a mail (as defined in the "letter"). This last part (= send the mail) is not yet developped. (Should be done this week)
1649 # * adding feature : it's now possible to "put to an alert" in OPAC, for any serial subscription. The alert is stored in a new table, called alert. An alert can be put only if the librarian has activated them in subscription (and they activate it just by choosing a "letter" to sent to borrowers on new issues)
1650 # * adding feature : librarian can see in borrower detail which alerts they have put, and a user can see in opac-detail which alert they have put too.
1652 # Note that the system should be generic enough to manage any type of alert.
1653 # I plan to extend it soon to virtual shelves : a borrower will be able to put an alert on a virtual shelf, to be warned when something is changed in the virtual shelf (mail being sent once a day by cron, or manually by the shelf owner. Anyway, a mail won't be sent on every change, users would be spammed by Koha ;-) )
1655 # Revision 1.115 2005/08/02 16:15:34 tipaul
1656 # adding 2 fields to letter system :
1657 # * module (acquisition, catalogue...) : it will be usefull to show the librarian only letters he may be interested by.
1658 # * title, that will be used as mail subject.
1660 # Revision 1.114 2005/07/28 15:10:13 tipaul
1661 # Introducing new "Letters" system : Letters will be used everytime you want to sent something to someone (through mail or paper). For example, sending a mail for overdues use letter that you can put as parameters. Sending a mail to a borrower when a suggestion is validated uses a letter too.
1662 # the letter table contains 3 fields :
1663 # * code => the code of the letter
1664 # * name => the complete name of the letter
1665 # * content => the complete text. It's a TEXT field type, so has no limits.
1667 # My next goal now is to work on point 2-I "serial issue alert"
1668 # With this feature, in serials, a user can subscribe the "issue alert". For every issue arrived/missing, a mail is sent to all subscribers of this list. The mail warns the user that the issue is arrive or missing. Will be in head.
1669 # (see mail on koha-devel, 2005/04/07)
1671 # The "serial issue alert" will be the 1st to use this letter system that probably needs some tweaking ;-)
1673 # Once it will be stabilised default letters (in any languages) could be added during installer to help the library begin with this new feature.
1675 # Revision 1.113 2005/07/28 08:38:41 tipaul
1676 # For instance, the return date does not rely on the borrower expiration date. A systempref will be added in Koha, to modify return date calculation schema :
1677 # * ReturnBeforeExpiry = yes => return date can't be after expiry date
1678 # * ReturnBeforeExpiry = no => return date can be after expiry date

1684 # we have decided that moving to Koha 3.0 requires being already in Koha 2.2.x
1685 # So, the updatedatabase script can highly be cleaned (90% removed).
1686 # Let's play with the new Koha DB structure now ;-)
