-of over two years of hard and dedicated work by volunteers all over the world
-under the lead of Dave Miller.
+There are usually many other bug fixes than those listed below,
+but the below fixes are the ones that we thought System Administrators
+would like to specifically know about.
 
-This is a preliminary document detailing how we expect things to be in the
-final 2.18 release.  The contents of this document are subject to change up
-until the final release.  Please file bugs in Bugzilla for any additions or
-corrections needed in this document.

+Generic Charting
+----------------
+
+Bugzilla has a new mechanism for generating charts (graphs over time) of any
+arbitrary search. This is known as "New Charts." Legacy data from the previous
+charting mechanism ("Old Charts") is migrated into the "New Charts" when you
+upgrade. The Old Charts mechanism remains, but is deprecated and will be 
+removed in a future version of Bugzilla.
+
+Individual users can see/create charts as long as they are a member of the 
+group specified in the Param 'chartgroup'. Data can be collected for 
+personal charts every seven days (or a longer period, as set by the user). 
+Charts created by an administrator can be made public (visible to all). Data 
+is collected for administrator charts every day (or a longer period, as set 
+by the admin).
+
+The data is collected by the collectstats.pl script, which an administrator 
+will need to arrange to be run once every day (see the manual). Chart data can
+be plotted in a number of different ways, and different data sets can be
+plotted on the same graph for comparison.
+
+Please see the Known Bugs section for some important limitations relating to
+access controls on charts.

 Recommended Practice for the Upgrade
 ************************************
 
-As always, please ensure you have run checksetup.pl after replacing the
-files in your installation.
+Note About Upgrading From MySQL With ISAM Tables
+------------------------------------------------
+As previously noted in the Dependency Requirements MySQL is now required 
+to be at least version 3.23.41.  This implies that all tables of type ISAM will 
+be converted by the checksetup.pl script to MyISAM.
+
+
+Steps for Upgrading
+-------------------
+
+1) View the Sanity Check (sanitycheck.cgi) page on your installation before
+   upgrading.
+
+2) As with any upgrade it is recommended that you make a backup of the 
+   Bugzilla database before you upgrade, perhaps by using mysqldump.
+
+   Example:
+
+      mysqldump -u root -p --databases bugs > bugs.db.backup
+
+3) Replace the files in your installation, or you can try to use CVS to upgrade.
+   The Bugzilla.org website has instructions on how to do the actual 
+   installation.
 
-It is recommended that you view the sanity check page (sanitycheck.cgi) both
-before the upgrade and after running checksetup.pl after the upgrade, to see
-if there are any problems with your installation.
+4) Make sure that you run checksetup.pl after you install the new version.
 
-It is also recommended that, if possible, you fix any problems you find
-immediately. Failure to do this may mean that Bugzilla will not work correctly.
-Be aware that if the sanity check page contains more errors after an upgrade,
-it doesn't necessarily mean there are more errors in your database, as
-additional tests are added to the sanity check over time, and it is possible
-that those errors weren't being checked for in the old version.
+5) View the Sanity Check page again after you run checksetup.pl.
 
-As previously noted in the Dependency Requirements MySQL is now required to be
-at least version 3.23.41.  This implies that all tables of type ISAM will be
-converted by the checksetup.pl script to MyISAM.  As with any upgrade it is
-recommended to make a backup of the database, perhaps by using mysqldump.
+6) It is recommended that, if possible, you fix any problems you find
+   immediately. Failure to do this may mean that Bugzilla will not work 
+   correctly. Be aware that if the sanity check page contains more errors after
+   an upgrade, it doesn't necessarily mean there are more errors in your

+
+
+Outstanding Issues
+******************
+
+These are known problems with the release that we think you should know about. 
+They each have a bug number for http://bugzilla.mozilla.org/
+
+- If at any time you upgraded from a version of Bugzilla between 2.17.4 -
+  2.17.7 to either 2.18rc3 or 2.19.1, you must manually fix your New Charts in
+  order for them to work. See the following link for instructions on how to do
+  this: https://bugzilla.mozilla.org/show_bug.cgi?id=276237#c18
+  If you are using 2.18rc3, but did not upgrade from version 2.17.4 or newer,
+  then you don't need to do this.
+
+- bug 37765: If you use an MTA other than sendmail (such as Postfix, Exim, 
+  etc.) you MUST turn on the "sendmailnow" parameter or Bugzilla will not send
+  e-mail correctly.
+
+- bug 276230: The support for restricting access to particular Categories of 
+  New Charts is not complete. You should treat the 'chartgroup' Param as the 
+  only access mechanism available. However, additionally, charts migrated from
+  Old Charts will be restricted to the groups that are marked MANDATORY for 
+  the corresponding Product. There is currently no way to change this 
+  restriction, and the groupings will not be updated if the group configuration
+  for the Product changes.
+
+- bug 69621: If you rename or remove a keyword that is in use on bugs, you will
+  need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing
+  the option to rebuild the cache when it asks. Otherwise keywords may not show
+  up properly in search results.
+
+- (No Bug Number) If you have a lot of non-ASCII data in your Bugzilla (for 
+  example, if you use a translation of Bugzilla), don't enable the XS::Stash
+  option when you install the Template Toolkit, or your Bugzilla installation
+  may become slow. This problem is fixed in a not-yet-released version of the
+  Template Toolkit (after 2.14).
+
+- bug 266579: Users may be able to circumvent not having "canconfirm" privileges
+  in some circumstances. This is fixed starting with 2.19.3, but will not
+  be fixed in any 2.18 release, as the changes require to fix it are quite
+  large.
+
+- bug 99215: Attachment changes have no mid-air collision detection, unlike bug
+  changes.
+
+- bug 57350: Searching using the "commenter is" option may be VERY slow. Note 
+  that searching for "field: comment, changed by: user@domain.com" is fast, 
+  though.
+
+- bug 151509: Using the boolean chart option "contains the string" with the 
+  "flag name" field or certain other fields will cause Bugzilla to emit an 
+  error.
+
+- bug 225042: If sendmail dies while you are marking a bug as a duplicate, 
+  the duplicates table can become corrupted.
+
+- bug 234159: Bugzilla may sometimes send multiple notices in one email.
+
+- bug 237107: If you search for attachment information using the Boolean Charts
+  at the bottom of the Advanced Query page, bugs without attachments will not
+  show up in the result list.
+
+
+Security Fixes In 2.18 Releases
+*******************************
+
+Version 2.18
+------------
+
+Summary:     XSS in Internal Error messages in Bugzilla 2.16.7 and 2.18rc3
+CVE Name:    CAN-2004-1061
+Reference:   https://bugzilla.mozilla.org/show_bug.cgi?id=272620
+Details:
+     It is possible to send a carefully crafted URL to Bugzilla designed to
+trigger an error message.  The Internal Error message includes javascript code
+which displays the URL the user is visiting.  The javascript code does not
+escape the URL before displaying it, allowing scripts contained in the URL to
+be executed by the browser.  Many browsers do not allow unescaped URLs to be
+sent to a webserver (thus complying with RFC 2616 section 2.3.1 and RFC 2396
+section 2.4.3), and are thus immune to this issue.
+    Browsers which are known to be immune: Firefox 1.0, Mozilla 1.7.5,
+Camino 0.8.2, Netscape 7.2, Safari 1.2.4
+     Browsers known to be susceptible: Internet Explorer 6 SP2,
+Konqueror 3.2
+     Browsers not listed here have not been tested.
+
+
+Version 2.18.1
+--------------
+
+Two security issues were fixed in Bugzilla 2.18.1, neither of them 
+critical.
+
+See http://www.bugzilla.org/security/2.16.8/ for details.

+*********************************************************
+
+*** Security fixes ***
+
+- It is possible to send a carefully crafted HTTP POST message to
+  process_bug.cgi which will remove keywords from a bug even if you don't have
+  permissions to edit all bug fields (the "editbugs" permission).  Such changes
+  are reported in "bug changed" email notifications, so they are easily
+  detected and reversed if someone abuses it.  Users are now prevented from
+  making changes to keywords if they do not have editbugs privileges. (bug
+  252638)
+
+*** Bug fixes of note ***
+
+- Enforce a minimum of 10 minutes between attempts to reset a password, so
+  we don't mailbomb the user if someone submits the form many times in a
+  row. (bug 250897)
+
+- Put products in alphabetical order on the create attachment status page.
+  (bug 251427)
+
+- Specify MyISAM as the table type when creating new tables.  MySQL 4.1 and
+  up default to InnoDB, which doesn't support some of the indexing methods
+  that we use. (bug 263165)

+*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.6 ***
+*********************************************************

+*** Security fixes ***
+
+- If Bugzilla is configured to hide entire products from some users, both

+  can disclose the names of those hidden products to such users.
+  (bugs 234825 and 234855)
+
+- Several administration CGIs echo invalid data back to the user without
+  escaping it.  (bug 235265)
+
+- A user with privileges to grant membership to any group (i.e. usually an
+  administrator) can trick editusers.cgi into executing arbitrary SQL.
+  (bug 244272)
+
+*** Bug fixes of note ***

+- Allow XML import to function when there are regexp metacharacters in product
+  names (bug 237591) 
+
+- Allow the bug_email.pl contrib script to work with useqacontact (bug 239912) 
+
+- Improve the error message used by checksetup.pl when the MySQL requirements
+  are not met (bug 240228) 
+
+- Elimnate the warning in checksetup.pl about the minimum sendmail version (bug
+  240060) 
+
+- $webservergroup now defaults to group 'apache' in new installations (bug
+  224477)

+- Correct a situation where a bugmail message could be sent twice to a user
+  being added to the CC list if the address was entered in a different case
+  than the user registered with.  (bug 117297)

+- No longer use server push with the "Safari" browser, which claims to
+  use the Mozilla layout engine but doesn't.
+  (bug 188712)
+
+- Creating a shadow database no longer fails with taint mode errors.
+  (bug 227510)
+  
+- If you change your cookiepath setting at some stage (because you have
+  moved the directory Bugzilla resides on your webserver), users can
+  have login cookies with the old cookiepath, and their browsers will
+  send multiple logincookies.  Bugzilla now uses the first rather than
+  the last in order to get the most specific cookie which will be the
+  correct one.
+  (bug 121419)	
+  
+- Fixed a regression caused by the previous DBD::mysql fixes, that
+  caused older versions of DBD::mysql to break due to not supporting
+  the new DBI syntax.
+  (bug 224815)
+
+- Bugzilla no longer sends out invalid dates for cookie expiry.  This

+  (bug 217422)
+
+DBD::mysql > 2.1026 Compatibility fixes:
+
+- DBD::mysql versions after 2.1026 return the table list quoted, which

+  the second and subsequent attempts to run checksetup.pl to fail.
+  (bug 212095) 
+
+Miscellaneous bug fixes:
+
+- A Mozilla-specific reference was removed from one of the report
+  templates.
+  (bug 221626)
+
+- It was possible to enter a situation where you were unable to get to

+  would get recreated with the file owner being the user the cron job
+  was running as (usually not the webserver user), causing subsequent

+*********************************************************
+*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.2 ***
+*********************************************************
+
+*** SECURITY ISSUES RESOLVED ***
+
+- A cross site scripting (XSS) vulnerability was fixed in which bug 
+  summaries were not properly filtered when a user viewed a dependency graph 
+  allowing JavaScript to be embedded on that page.
+  (bug 192661)
+  
+- Several XSS vulnerabilities were fixed in which user
+  input was not escaped when being displayed. A new 
+  test has been added to warn about unfiltered data in template
+  files (t/008filter.t).
+  (bug 192677)
+
+- An issue was fixed in which the QA contact was still treated as the QA
+  contact even after the 'useqacontact' setting was turned off. This also
+  allowed the QA contact to edit the security groups and view secured bugs that
+  he/she was allowed to access prior to the 'useqacontact' setting being
+  deactivated.
+  (bug 194394)
+  
+- Fixed a situation where an attacker (with local access to the webserver)
+  could overwrite any file on the webserver to which the webserver user
+  has write access by creating appropriately named symbolic links in the
+  data and webdot directories (world-writable in many configurations).
+  Bugzilla now uses File::Temp to create secure temporary files.  File::Temp
+  is part of the Perl distribution for Perl 5.6.1 and later, but if you're
+  using an older version of Perl you'll need to install it with CPAN.
+  (bug 197153)
+
+** IMPORTANT CHANGES ***
+
+- New module requirement: File::Temp, as mentioned above.
+
+*** Bug fixes of note ***
+
+- An issue was fixed in which administrator rights could be removed from an
+  administrator who deleted a product while the 'usebuggroups' setting is
+  activated.
+  (bug 157704) 
+  
+- Fixed an issue in which importxml.pl would fail the test suite when running
+  under perl 5.8.0 with the optional XML::Parse module. 
+  (bug 172331)
+  
+- There was previously a bug in CGI.pl in which the following warning 
+  would be given under certain conditions: 
+  "Character in "c" format wrapped at CGI.pl..." 
+  This is now fixed. In some cases the warning was filling up web server log
+  files.
+  (bug 194125)
+  
+- Fixed a bug in which long component names (in excess of 50 characters) would

+
+*** IMPORTANT CHANGES ***
+
+- 2.16 introduces "templatisation", a new feature that allows
+  administrators to easily customise the HTML output (the "look and feel")
+  of Bugzilla without altering Perl code.  Bugzilla uses the
+  "Template Toolkit" for this.  Please see the "Template Customisation"
+  section of the Bugzilla Guide for more details.
+
+  Administrators who ran the 2.15 development version and customised
+  templates should check the templates are still valid, as file names
+  and file paths have changed.
+
+  Most output is now templatised.  This process will be complete next
+  milestone.
+
+  For speed, compiled templates are cached on disk.  If you modify the
+  templates, the toolkit will normally detect the changes, and recompile the
+  changed templates.
+
+  Adding new directories anywhere inside the template directory may cause 
+  permission errors if you don't have a webservergroup specified in
+  localconfig.  If you see these, rerun checksetup.pl as root.  If you do not
+  have root access, or cannot get someone who does to do this for you, you can
+  rename the data/template directory to data/template.old (or any other name
+  Bugzilla doesn't use).  Then rerun checksetup.pl to regenerate the compiled
+  templates.
+  (bug 86168, 97832)
+
+- Administrators can now configure maximum attachment sizes.  These
+  should remain below the maximum size for your MySQL server, or you
+  will get obscure MySQL errors if you attach a bigger attachment.
+
+  To find out the current size attachment that MySQL can accept, type
+  the command 'mysqladmin variables' and find out the value of the
+  'max_allowed_packet' varible in bytes.
+
+  To change the maximum size that MySQL can accept you can alter this
+  variable in your 'my.cnf' file.
+  (bug 91664)
+
+- Perl 5.004 is no longer supported because the Template Toolkit
+  requires 5.005.
+  (bug 97721)
+
+- New module requirements: Text::Wrap, Template [requires AppConfig],
+                           File::Spec.
+  (bugs 97784, 84338, 103778)
+
+- The index page is now a CGI instead of an HTML page.  You should remove
+  any existing index.html file and make sure your web server allows index.cgi
+  to be the default page in a directory.  If you are not able to do that you
+  can instead set index_html in the 'localconfig' file to 1 and checksetup.pl
+  will create a redirect page for you.
+  (bug 80183)
+
+- It is now recommended that administrators run "processmail rescanall"
+  after upgrading to 2.16 or beyond.
+
+  This will send out notification emails for changes that were
+  made but not emailed, due to Bugzilla bugs.  All known
+  causes of this have been fixed in this version (bug 104589 and 99519).
+
+  It is also recommended that this be run nightly to avoid
+  lengthy delays in future if this problem reoccurs.
+  (bug 106377)
+
+- In parallel with templatisation, a lot of changes have been made to the HTML
+  output of the Bugzilla CGIs.  This could break code that attempts to parse
+  such code.  For example, this breaks mozbot.
+  (no bug number)
+
+- The "HTML template" parameters (headerhtml, bodyhtml, footerhtml,
+  errorhtml, bannerhtml, blurbhtml, mostfreqhtml, entryheaderhtml) have now
+  been moved to Template Toolkit templates.  If you have modified these
+  parameters you will need to make corresponding changes to the corresponding
+  templates.  Your old parameter values will be moved to a file called
+  old-params.txt by checksetup.pl.
+
+  The old parameters correspond to files in template/en/default as follows:
+
+  headerhtml:      global/header.html.tmpl
+  footerhtml:      global/footer.html.tmpl
+  bannerhtml:      global/banner.html.tmpl
+  blurbhtml:       global/banner.html.tmpl
+  mostfreqhtml:    reports/duplicates*.html.tmpl
+  entryheaderhtml: bug/create/user-message.html.tmpl

+  (bug 38835)
+- Bug counts (on reports.cgi) were very slow if you had to
+  count a lot of bugs.
+  (bug 63249)
+- 2.14 introduced options to let people see a bug when their name
+  is on it but who aren't in the groups the bug is restricted
+  to.  These only allowed the people to view the bugs directly,
+  and not see them on buglists and receive email about them.
+  (bugs 95024, 97469)
+- A new 'cookiepath' parameter on editparams.cgi allows multiple
+  Bugzilla installations to exist on one host without problems.

+  (bug 108385, 108516)

+- The Product popup menu on the show_bug form listed all
+  products, even if the user didn't have access to all of them.

+
+- After logging in passwords no longer appear in the URL.
+  (bug 15980)
+
+- Procedures to prevent unauthorised access to confidential
+  files are now simpler.  In particular the shadow directory
+  no longer exists and the data/comments file no longer needs
+  to be directly accessible, so the entire data directory can
+  be blocked.  However, no changes are required here if you
+  have a properly secured 2.12 installation as no new files
+  must be protected.
+  (bug 71552, 73191)

+
+- Sanity check can now only be run by people in the 'editbugs'
+  group.  Although it would be better to have a separate
+  group, this is not possible until the limitation on the
+  number of groups allowed has been removed.
+  (bug 54556)
+
+- The password is no longer stored in plaintext form.  It will
+  be eradicated next time you run checksetup.pl.  A user must
+  now change their password via a password change request that
+  gets validated at their e-mail account, rather than have it
+  mailed to them.
+  (bug 74032)
+
+- When you are using product groups and you move a bug between
+  products (single or mass change), the bug will no longer be
+  restricted to the old product's group (if it was) and will

+  the reporter cannot see you will be given options as to
+  what to do regarding adding the reporter of the resolved
+  bug to the CC of the open bug.
+  (bug 96085)
+
+*** IMPORTANT CHANGES ***
+
+- Bugzilla 2.14 no longer supports old email tech.  Upon
+  upgrading, all users will be moved over to new email tech.
+  This should speed up upgrading for installations with
+  a large number of bugs.
+  (bug 71552)
+
+- There is new functionality for people to see why they are
+  receiving notification mails.
+
+  Previously, some people filtered old email tech
+  notifications depending on whether they were in the To or the
+  CC header, in order to get a limited way of determining why
+  they were receiving the notification for filtering purposes.
+
+  Existing installations will need to make changes to support
+  this feature.  The receive reasons can be added to the
+  notifications as a header and/or in the body.  To add these
+  you will need to modify your newchangedmail parameter on
+  editparams.cgi, either by resetting it or appropriately
+  modifying it.  The header value is specified by
+  %reasonsheader% and the body by %reasonsbody%.  For example,
+  the new default parameter is:
+
+  --------------------------------------------------
+  From: bugzilla-daemon
+  To: %to%
+  Subject: [Bug %bugid%] %neworchanged%%summary%
+  X-Bugzilla-Reason: %reasonsheader%

+
+  (bug 26194)
+
+- Very long fields (especially multi-valued fields like keywords,
+  CCs, dependencies) on bug activity and notifications previously
+  could get truncated, resulting in useless notifications and data
+  loss on bug activity.  Now the multi-valued fields only show
+  changes, and very big changes are split into multiple lines.
+  Where data loss has already occurred on bug activity, it is
+  indicated using question marks.
+  (bug 55161, 92266)
+
+- Previously, when a product's voting preferences changed all
+  votes were removed from all the bugs in the product.  Also,
+  when a bug was moved to another product, all of its votes
+  were removed.  This no longer occurs.
+
+  Instead, if the action would leave one or more bugs with
+  greater than the maximum number of votes per person per bug,
+  the number of votes will be reduced to the maximum.  The
+  person will still be notified of this as before.
+
+  If the action would leave a user with more votes in a product
+  than is allowed, the limit will be breached so as to not lose
+  votes.  However the user will not be able to update their
+  votes except to fix this situation.  No further action is taken
+  in this version to make sure that the user does this.
+  (bug 28882, 92593)
+
+*** Other changes of note ***
+
+- Groups can now be marked inactive, so you can't add a new
+  restriction on that group to a bug, while leaving bugs that
+  were previously restricted on that group alone.
+  (bug 75482)
+- backdoor.cgi has been removed from the installation.  It was
+  old code that was Netscape-specific and its name was scaring
+  people.
+  (bug 87983)
+- You can now add or remove from CC on the bulk change page.
+  (bug 12819)
+- New users created by administrators are now automatically
+  inserted into groups according to the group's regular
+  expression.  Administrators must edit the user in a second
+  step to override these choices.  Previously the
+  administrator specified these explicitly which could lead
+  to incorrect settings.
+  (bug 45164)
+- The userregexp of system groups can now be edited without

+  probably be improved in future versions.
+  (bug 17464)
+
+- "Changed" will no longer appear on the subject line of
+  change notification emails.  Because of this, you should
+  change the subject line in your 'changedmail' and
+  'newchangedmail' params on editparams.cgi.  The subject
+  line needs to be changed from
+
+    Subject: [Bug %bugid%] %neworchanged% - %summary%
+
+  to:
+
+    Subject: [Bug %bugid%] %neworchanged%%summary%
+
+  or whatever is appropriate for the subject you are using
+  on your system.  Note the removal of the " - " in the
+  middle.
+  (bug 29820)

+  Previously they wouldn't if you were using new email tech.
+  (bug 30826)
+- When marking a bug as a duplicate, the duplicate stamp marked
+  on the open bug will no longer be written too early (such as
+  on mid-air collisions).
+  (bug 7873)
+- Various bug fixes were made to the initial assignee and QA
+  of a component.  It is no longer possible to enter an
+  invalid address.  They will also now properly update when
+  a user's email address is changed.  Sanity check will now
+  check these.
+  (bug 66876)
+- Administrators can no longer create an email accounts that do
+  not match the global email regular expression parameter.
+  Previously this could occur and would cause sanity check
+  errors.
+  (bug 32971)
+- The resolution field can no longer become empty when the
+  bug is resolved.  This occurred because of midair collisions.
