Upgrade Information for previous releases of MRBS:
--------------------------------------------------
If you are upgrading from MRBS 1.2-pre3 or later, then MRBS will
automatically execute any necessary database upgrades when it is first
run. It will prompt you for a database (not MRBS) username and password
with rights to create and alter tables.
It would be a sensible precaution to take a backup of your database before
the upgrade.
1. Take a backup of your database, just in case.
2. Take a backup copy of your existing mrbs directory on your web server.
3. Upload all the files and directories, except the config file, in the web
directory of the release to your server, overwriting your existing files.
Note that if you are upgrading from MRBS 1.4.7 or earlier, the structure
of the config file has changed and you should create a new config file
based on config.inc.php-sample.
4. Go to MRBS in your browser. If a database upgrade is required, you'll be
prompted for a database (note database, not MRBS) username and password.
MRBS database upgrades are in general not backwards compatible, ie you won't
be able to run an older version of MRBS against a later version of the
database. You may therefore choose to make a copy of the database for test
purposes and check that the upgrade process works before performing the
upgrade on your production database.
See the advice in INSTALL about potentially creating a fresh "config.inc.php"
when you upgrade MRBS, especially for a major version change.
Upgrading from prior to MRBS 1.8.0
==================================
The following configuration settings have changed:
$area_list_format Redundant. All area and room lists are now select elements.
$display_calendar_bottom Redundant. The mini-calendars have moved.
$max_slots Redundant. The code has been rewritten.
$simple_trailer Redundant. There is no longer a trailer!
The following $strftime_format settings have changed:
'day_month' redundant
'dayname_cal' replaced by 'minical_dayname'
'month_cal' replaced by 'minical_monthname'
'monthyear' replaced by 'view_month'
Upgrading from prior to MRBS 1.7.1
==================================
The $year_range configuration setting has been abandoned. If you have
it in your config file it won't do anything.
Upgrading from prior to MRBS 1.7.0
==================================
As a security measure, custom HTML for areas and rooms has been disabled by
default, since it could be used to insert malicious JavaScript. However, if
you trust your admins you can re-enable it by setting the following in the
config file:
$auth['allow_custom_html'] = true;
Upgrading from prior to MRBS 1.6.0
==================================
If you upgrade to MRBS 1.6.0 and use your old config.inc.php file, you must
add a line near to the top of the file, just after the <?php tag, to make
the file read:
<?php
namespace MRBS;
Upgrading from prior to MRBS 1.5.0
==================================
MRBS's default authentication scheme changed from 'config' to 'db' with
the release of MRBS 1.5.0. If you had previously used the 'config' scheme
without specifically stating this in your config.inc.php you will need
to make a change to your config.inc.php after upgrading to MRBS 1.5.0. The
change you need is:
$auth["type"] = "config";
Upgrading from prior MRBS 1.4.9
===============================
MRBS now supports the $vocab_override config variable. See
systemdefaults.inc.php for more details. If you have customised your version
of MRBS by editing the lang files, you are advised to use $vocab_override instead.
This will make future upgrades easier.
Upgrading from prior MRBS 1.4.6
===============================
If you were previously using MRBS with $unicode_encoding set to 0, when
you upgrade to 1.4.6 you _MUST_ upgrade the MySQL database from the
previously used character set to Unicode. Note that it is extremely
unlikely that you will need to do this as the default setting of
$unicode_encoding is 1.
If you do need to convert text in the database you should run the
convert_db_to_utf8.php script _BEFORE_ upgrading to the latest version
of MRBS. The administrator should copy the file into the web directory,
run it (choosing the encoding to convert from) ONCE, and then move it back
out of the web directory. We recommend you backup your database before
running this script if you are at all worried. Running it more than once
will make a right mess of any non-ASCII text in the database.
Additionally, this script can correct an MRBS database that used to run on
an old version of MySQL (earlier than 4.1), but that now runs on a newer
version of MySQL. In this case, the database contains UTF-8 text, but the
tables are considered to be in some other encoding by MySQL, generally
Latin-1. The convert_db_to_utf8.php detects this condition, and offers
the administrator the chance to correct the database 'collation'.
===
The following configuration variables are now deprecated. Their use is
supported for the moment but you should change your config file now to
use the new variables as support for the old variables may be dropped in the
future:
$mail_settings['admin_all'] replaced by $mail_settings['on_new'] and
$mail_settings['on_change']
$mail_settings['admin_on_delete'] replaced by $mail_settings['on_delete']
$dateformat replaced by $strftime_format['daymonth']
Upgrading from prior MRBS 1.4.5
===============================
MRBS 1.4.5 introduces the concept of tentative bookings, or bookings that
require confirmation. To avoid confusion, what were previously known as
"provisional bookings" have now been renamed "bookings requiring approval"
and the config variable $provisional_enabled has been renamed
$approval_enabled. You should update your config file accordingly.
Please also see the note about database compatibility above.
Upgrading from prior MRBS 1.2-pre3
==================================
Upgrade to MRBS 1.2-pre3 first by following the upgrade instructions in that
release.
