Changelog

This file holds the changelog for Pepperminty Wiki. This is the master list of things that have changed (second only to the commit history!) - though the information for any particular release can also be found in the description of it's page for every release made on GitHub too.

v0.17

Fixed

• Removed stray debugging output
• Tweaked css to make new search context generation look better

v0.17-beta2

Fixed

• Fixed the cost-climbing bug in the last beta release

v0.17-beta1

Added

• [Module API] Added save_settings() convenience method
• [Rest API] Add user-add and set-password moderator actions
• Added random_page_exclude_redirects setting that prevents the random action from returning redirect pages.
• Added link to user table on the credits page
• Added history reversion via the history-revert action
• Added history_max_revisions setting to allow control of the maximum number of revisions stored for a page
  • Takes effect every time a page revision is added
• Added page restore system
  • A previous page revision can be restored with a single click from the page history page
  • Added a new history_revert_require_moderator setting to control whether moderator privileges are required to use the functionality (regardless of setting a user must be logged in)
• HTTP/2.0 Server Push support!
  • You'll need to make sure your web server has support turned on
  • The CSS file specified in the css setting (url path must begin with a forward-slash) and the favicon (must not be a data: url) are automatically pushed when rendering pages
  • 2 new settings have been added: http2_server_push for turning it on and off (defaults to on), and http2_server_push_items for specifying custom resources to push (in case you design your own theme and want to push down the associated resources)
  • More information about http2_server_push_items in particular is available on the configuration info page (when this release is out, of course. Until then, check out the description in peppermint.guiconfig.json)
• Added <meta name='generator' /> tag to all pages

Fixed

• Updated the search system to transliterate characters to better support searching pages that are written in other languages.
  • You'll want to rebuild your search index via the button in the configuration panel, or the invindex-rebuild action.
• [Security] Made the site secret generator cryptographically secure. If you created your wiki before this change, you might want to change your site secret in peppermint.json to something more secure with a site like random.org.
  • The PHP function openssl_pseudo_random_bytes() was being used before, but apparently that's not cryptographically secure.
• [Module API] Fix full_url() logic
• [Module API] Make email_user() correctly return email sending failures
• Squashed a warning in the search redirector
• The search redirector will now check both the specified page name and the page name in Title Case
• Improve help text description of image captions displayed alongside images
• Fixed the page history page - it should now display all page revisions in valid HTML
• Fixed another bug in the search context generator
• Display an ellipsis at the beginning of a search context if it doesn't start at the beginning of a page
• Semicolons are no longer automatically included in greedy internal links.
• Pressing enter in the tag box now correctly previews instead of performing a smart restore

Changed

• Password hashing has been overhauled! A totally new-and-different system is being used now, so you'll need to rehash all your passwords.
  • The hash action supports the new password hashing scheme.
  • Added password_cost, password_cost_time, and password_cost_time_interval settings
  • password_cost is recalculated automatically every week by default (it keeps track of this via the password_cost_time_lastcheck 'setting')
• The css setting will now keep a value of auto, even when peppermint.json is automatically updated by Pepperminty Wiki.
• Optimised the search system a lot (#157 - ~2800ms searches now take ~450ms O.o)
  • Tuned the default value for search_characters_context down to 75 (this won't be the case for existing wikis, so you'll need to adjust it manually)
  • Added new search_characters_context_total setting to control the maximum characters in a search context
• The index action's output should now be formatted nicely.
• Restyled "matching tags" in the search results in the default stylesheet
• Added moar icons to the nav / more menus. Delete the appropriate entries in peppermint.json to get the updated ones!

v0.13

(No changes were made between the last beta release and this release)

v0.13-beta2

Added

• Added new query-searchindex action to inspect the internals of the search engine
  • It returns the (ordered) search rankings as json, along with some additional debugging data

Fixed

• Clear the page id index out when rebuilding the search index from scratch.
  • This is needed to correct some issues where the id index goes all weird and assigns the same id to multiple pages

v0.13-beta1

Added

• Added header to upload file page.
• Added history support to the raw action.
• Added 'smart save' to the page creator / editor. Nobody need ever loose edits ever again!
• Added dynamic server-calculated page suggestions. Very helpful for larger wikis. Currently works best in Firefox. Part of the feature-search module.
• Added Alt + Enter support to the page search box. Works just like your browser's address bar - opens results in a new tab instead of the current one.
• Initial UI for configuring settings! Some things still have to be done by editing the file, but it's certainly a start :D
• User preferences!
  • Accessible via the (by default) small cog next to your username when you're logged in
  • The cog is customisable via the new user_preferences_button_text setting.
  • You can change your password
  • There's link to the master site settings from user preferences for admins.
• [Module API] Added $env->user_data and save_userdata() to interact with the logged in users' data
• User pages! Every page under Users/ by default belongs to their respective users. e.g. Users/admin and all the pages under it belong to the admin user, so no other user can edit them.
  • You can access your own user page by clicking on your username in the top corner when you're logged in.
  • Added the user_page_prefix setting to allow customisation of where user pages should be located. Default value: Users
  • [Module API] Added get_user_pagename() and extract_user_from_userpage() to allow programmatic detection etc.
• Added a user-list action that, well, outputs a list of users. Includes links to their respective user pages (though redlinks aren't implemented here yet).
• Internal links like [[Page name]]s will now link to the correct page in include the rest of the word. Note that this functionality can't be mixed with display text, like this: [[Page name|Display text]]s - the rest of the word will be silently ignored in the link!

Changed

• Overhauled internal history logic - history logic is now done in core.
• Added $env->page_filename, which points to the current page on disk.
• Changed the way different display modes are accessed. You can now use the new mode parameter to the view action. It supports 4 different modes at present: normal, printable, contentonly, and parsedsourceonly.

• Improved tabbing through the file upload form.
• Changed the way users' data is stored to support arbitrary per-user data
• Sorted list of registered actions on the dev help page
• The page editor's main content box now automatically expands as you're typing! If you've got a custom theme, you may need to tweak it a bit. Help available on request.
• Pages that are redirects how have their names appear in italics in search results.

Fixed

• The login session lifetime is now configurable (defaults to 24 hours), so you won't keep getting logged out all the time (in theory). (#113)
• Recent changes made on different days are now displayed separately, as they should be (#112)
• Always display footer message at the bottom of the page.
• Trim the image url before short image url detection (#108)
• Fixed huge issue with contentonly display mode.
• Improved the search engine indexing algorithm. It now shouldn't choke on certain special characters ([]{}|) and will treat them as word boundaries.
• Fixed tag links at the bottom of pages for tags with a single quote (') in them.
• Correct error message when attempting to move a page
• Improved security of PHP session cookie by setting HttpOnly flag.
