------------------------------------------------------------------------------
* 0.19.1
New Features:
* From the "All" or Category listings, you can export selected pages (in any
desired order) to a single LaTeX file.
* LaTeX export supports \array{} (with no options) and a LaTeX-style optional
argument for \sqrt[]{}. The latter requires itextomml 1.4.5 or later.
* Updated to itextomml 1.4.5 (a bunch of new itex language features).
* Updated to Rails 2.3.10. (There were security issues in 2.3.9 which, happily,
did NOT affect Instiki 0.19. But 2.3.10 has other improvements, as well.)
Bugs Fixed:
* Several SVG-Edit bugs fixed.
* Removed some superfluous junk, to slim down the distribution (cuts the size of
the compressed .tar.gz nearly in half).
------------------------------------------------------------------------------

(and whenever you update), run
ruby bundle
rake upgrade_instiki
from the instiki directory. (You may need to run
ruby bundle exec rake upgrade_instiki
instead, if you get a complaint about your version of rake.)
Bugs Fixed:
* Works with Ruby 1.9.2
* Fixed a bug in non-Latin WikiWord processing. (Reported by Alexander Hambug)

previous revision pages.
* Fix HTML Export feature so that uploaded files are
included, stylesheets load, etc.
* Uploaded files inclided in Markup Export.
* Fix Print View, so that uploaded images work.
* Fix some more Ruby 1.9 isues.
* Prevent page from being renamed to null.
* Fix Migration to work under PostgreSQL (from J. Zellman).
* Updated vendored plugins
------------------------------------------------------------------------------
* 0.18.1
New Features:
* (Markdown-Extra syle) fenced codeblocks. [From Jason Blevins]
* Fortran syntax colouring. [From Jason Blevins]
Bugs Fixed:
* Fixed some Ruby 1.9 encoding issues, with unicode page names,
author names and categories.
* Better display of inter-web wikilinks
* various syntax-colouring fixes
* Corrected length of wiki_references referenced_name (affects
MySQL users)
------------------------------------------------------------------------------
* 0.18
New Features:
* Syntax colouring: 'ansic', 'javascript', 'sqlite', 'yaml' and 'css' modes,
in addition to the existing 'html', 'xml', and 'ruby' modes,
* Source view [suggested by Andrew Stacey]
* Auto-resizing Textareas scale to fit viewing area.
* Instiki upgraded to Rails 2.3.5 and Rack 1.1.
* Now runs on Ruby 1.9. (If you're a Passenger user, you may need to upgrade to Passenger
2.2.8, which works around some bugs in Ruby 1.9.1.)
* Upgraded for itex2MML 1.3.19 (which works under Ruby 1.9, and has several new feautures,
relative to 1.3.15).
Bugs Fixed:
* Fixed a CSS bug, which screwed up printing (unless you used the "Print" view).
* Fixed a well-formedness bug in the page-name truncation algorithm [reported by Toby Bartels]
* Fixed a cache-sweeping bug [reported by Toby Bartels]
* Better accessibility.
* Improved log rotation under Passenger.
* Omit a (seemingly superfluous) javascript hack which causes Gecko-based browsers to request
/my_wiki/s5/null
when they load an s5 slideshow.
* Upgraded vendored sqlite3-ruby and rubyzip
* Move files when renaming a web (so that links to uploaded files don't break).
* Many Ruby 1.9 fixes, including removing the html5lib Sanitizer.
------------------------------------------------------------------------------
* 0.17.3
The most important facet of this release is a small change in the database
schema. Previously, people migrating from the default SQLite3 database to MySQL
ran the risk of silent data loss, because MySQL had a more strict interpretation
of the column types in the database. The new schema will prevent such problems.
rake upgrade_instiki
will seamlessly upgrade your existing database to the new schema.
New Features:
* Passenger support (including X-Sendfile support, if the Apache mod_xsendfile
module is installed).
* Update for itex2MML 1.3.13. (You should upgrade your itex2MML to the latest
version, too.)
Bugs Fixed:
* Refactored the Web model (from James Herdman).
* Clean malformed utf-8 strings, rather than complaining about them.
* Updated location of Textile help, since _why_the_lucky_stiff left the 'net.
* Fixed a TeX rendering bug.
* Updated list of XHTML+MathML named entities to match W3C Working Draft.
* Refactored the Sanitizer (speedup).
* Fix S5 Slideshows for non-root Instiki URLs.
* Work around a Rails flash bug.
* Links from published webs should work right (finally?).
* An important database migration for MySQL users.
------------------------------------------------------------------------------
* 0.17.2
Security: Updated to Rails 2.3.4
* Fixes Timing Weakness in Rails MessageVerifier and the Cookie Store
http://weblog.rubyonrails.org/2009/9/4/timing-weakness-in-ruby-on-rails
* Fixes XSS Vulnerability in Rails
http://weblog.rubyonrails.org/2009/9/4/xss-vulnerability-in-ruby-on-rails
New Features:
* Syntax colouring (`ruby` and `html`) for code blocks.
* Updated for itex2MML 1.3.10 (supports \rlap{} and \underline{}). You should upgrade that, too.
* Add a "Create New Page" Link to the Search Page. (Based on an idea by nowa)
* Updated to Rails 2.3.4
Bugs Fixed:
* Wikilinks to published webs should be to the published action. This didn't work
right for inter-web links. (Reported by Mike Shulman)
* Use .size, rather than .length for ActiveRecord associations. A huge memory saving
in building the recently_revised page.
* Refactor the upgrade_instiki rake task, to make it database-agnostic. (Many thanks to James Herdman)
* Web#files_path and Web#blatex_pngs_path now return Pathname objects. (Thanks, again, to James Herdman)
* Workaround for Mozilla Bug 449396. (Reported by Andrew Stacey)
* Correctly Set noindex,nofollow On /diff Pages.
* Page-renaming javascript deals correctly with page names containing ampersands, slashes, and other garbage.
* List of Wanted Pages should not include redirected pages.
* The Regexp, used in Maruku to detect "email" headers (used, e.g., for S5 slideshow metadata) could, for some inputs, interact badly with Instiki's Chunk Handler. Fixed.
* Ensure "rollback" locks page for editing.
* Generate relative URLs, when possible. (Patch by Dennis Knauf)
* Expire revisions of an edited page. Use a `before_save` hook to deal with the situation where a page's name has been changed.

= Instiki
Instiki is a wiki clone so pretty and easy to set up, you'll wonder if it’s really a wiki. Runs on Rails and focuses on portability and stability. Supports file uploads, PDF export, RSS, multiple users and password protection. Some use Instiki as a CMS (Content Management System) because of its ability to export static pages.

== Migrating from Instiki 0.11-0.18 to 0.19
== Migrating from Instiki 0.11-0.12 to 0.16.3
rake upgrade_instiki
== Migrating Instiki 0.10.2 storage to Instiki 0.11.0 database
1. Install Instiki 0.11 and check that it works (you should be able to create a web, edit and save a HomePage)
2. Execute
ruby script\import_storage \
-t /full/path/to/instiki0.10/storage \
-i /full/path/to/instiki0.10/installation \
-d sqlite (or mysql, or postgres, depending on what you use) \
-o instiki_import.sql
for example (Windows):
ruby script\import_storage -t c:\instiki-0.10.2\storage\2500 -i c:\instiki-0.10.2 -d sqlite -o instiki_import.sql
3. This will produce instiki_import.sql file in the current working directory.
Open it in a text editor and inspect carefully.
4. Connect to your production database (e.g., 'sqlite3 db\prod.db'),
and have it execute instiki_import.sql (e.g., '.read instiki_import.sql')
5. Execute ruby script\reset_references
(this script parses all pages for crosslinks between them, so it may take a few minutes)
6. Restart Instiki
7. Go over some pages, especially those with a lot of complex markup, and see if anything is broken.
The most common migration problem is this: if you open All Pages and see a lot of orphaned pages,
you forgot to run ruby script\reset_references after importing the data.
===Upgrading from Instiki-AR Beta 1
In Beta 2, we switch to ActiveRecord:Migrations. Therefore:
1. Back up your production database.
2. Open command-line session to your database and execute:
create table schema_info (version integer(11));
insert into schema_info (version) values (1);
3. Go back to the shell, change directory to the new Instiki and execute "rake migrate".
Step 2 creates a table that tells to ActiveRecord:Migrations that the current version
of this database is 1 (corresponding to Beta 1), and step 3 makes it up-to-date with
the current version of Instiki.

UPGRADING
=========
See the upgrading instructions
http://golem.ph.utexas.edu/wiki/instiki/show/Upgrading
for detailed instructions.
At a minimum, you need to backup your database.
After installing the new software and restoring your database, you need to run
ruby bundle
ruby bundle exec rake upgrade_instiki
from the commandline, to complete the upgrade. Doing a
ruby bundle update
will update the installed gems (used by Instiki) to the latest versions.

# == Introduction
#
# This module provides sanitization of XHTML+MathML+SVG
# and of inline style attributes. Its genesis is {described here}[http://golem.ph.utexas.edu/~distler/blog/archives/001181.html].
#
# Uses the {HTML5lib parser}[http://code.google.com/p/html5lib/], so that the parsing behaviour should
# resemble that of browsers.
#
# sanitize_xhtml() is a case-sensitive sanitizer, suitable for XHTML
# sanitize_html() is a case-insensitive sanitizer suitable for HTML
# sanitize_rexml() sanitizes a REXML tree, returning a string
# safe_sanitize_xhtml() makes extra-sure that the result is well-formed XHTML
# by running the output of sanitize_xhtml() through REXML

of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.
