Raw Blame History

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.

v0.20-dev

  • Made build.sh build script more robust, especially when generating the documentation.

v0.19

(No changes have been made since the last beta release.)

v0.19-beta2

Changed

  • Updated the theme of the new documentation
  • Revised the writing modules section of the documentation

v0.19-beta1

The update that changed the world! Turn everything upside-down.

Fixed

  • Fixed double-escaping of rendered HTML when nesting templates
  • Squashed a warning if the search index doesn't exist yet
  • Fixed a crash in the stats updater if no pages in the system have tags yet
  • Consolidated email and emailAddress fields into the latter in the user table (#167)
  • Fixed a crash when trying to access the user table when not logged in as an administrator.
  • Fixed help text for the file upload module
  • Squashed a warning when uploading a file

Added

  • [Module API] Added new extra data system. See parser-parsedown and page-edit for an example.
    • Extra data is packed into a zip archive, which is packed into index.php via __halt_compiler();
    • See the parser-parsedown and page-edit modules for examples on how to use it.
  • [Module API] Added new delete_recursive() function.
  • Added a new obvious link to the user table at the top of the master settings page.
  • Added a new first-run wizard to help new users set up the basics of their wiki.
    • It also checks to ensure that access to peppermint.json is blocked correctly (coming soon as a one-time check to pre-existing wikis)
    • Pre-existing wikis will not see this first-run wizard - a new firstrun_complete setting has been added that's automatically set to true if Pepperminty Wiki does a settings upgrade
  • Default to allowing lossless flac and ogg audio files to be uploaded
  • Added new minify_pageindex setting, which defaults to true and causes the page index to be minified when saved. Improves performance slightly (especially on larger wikis as the page index grows), but makes debugging and ninja-edits more awkward.
  • [Module API] Added new save_pageindex() function which respects the above setting.
  • Added PDF preview using your browser's default PDF viewer!
  • Added download button for unsupported file types

Changed

  • Core sharding: split core.php into multiple files
  • Big update to the backend Markdown parser Parsedown
    • Use Parsedown's new untrusted feature for comments
    • Added new all_untrusted setting to allow treating everything as untrusted (default: false) - turn it on if your wiki allows anonymous edits
  • Switch to nightdocs instead of docpress (the official docs will update & change URL on the next stable release) the new docs are available here!
  • Add moar badges to the README & docs :D

Removed

Not often I have a removed section!

  • [Module API] Remove remote file system in favour of the new extra data system. No more first-run downloads! They are all done at compile-time now.

v0.18

(No changes have been made since the last beta release.)

v0.18-beta1

Added

  • Added inter-wiki link support via the new feature-interwiki-links module
    • Added interwiki_index_location setting to control the location of the interwiki index (which is a CSV file that is documented in the main Pepperminty Wiki documentation), which has to be specified in order for it to activate
    • Provides new module api functions: interwiki_pagename_parse, interwiki_pagename_resolve, interwiki_get_pagename_url, and is_interwiki_link
  • Added new formats to the recent-changes action (append &format=XXX to the url)
    • Added CSV support (csv)
    • Added Atom 1.0 feed support (atom)
    • All alternative formats for this action are advertised in via a <link rel="alternate" /> in the <head> now
  • Added count and offset GET parameters to recent-changes action.
  • Added new find_revisionid_timestamp() function to feature-recent-changes module.
  • Added new parser output caching system!
    • Saves to ._cache in the data directory (alongside the pages themselves)
    • 2 new settings have been added: parser_cache and parser_cache_min_size
    • Uses a hash of the content, the Pepperminty Wiki version, and the parser name as the cache id - so it should never serve stale content (unless you're actively working on particular areas of Pepperminty Wiki's codebase of course)
    • Useful for longer pages
    • parser_cache_min_size may need tuning for your specific installation (lower it if you regularly use features that are slow to parse; raise if it's the opposite)
  • Internal links now show the page name on hover (inter-wiki links are also supported here)

Changed

  • Completely reworked the README to refactor out the documentation to its own static site
  • Updated the {{{@}}} templating variable to output a message if no parameters were specified instead of not parsing it at all
  • [Module API] Refactored the main page_renderer class
    • All static methods now have a consistent naming scheme
    • Added page_renderer::add_header_html()

Fixed

  • Squashed a warning in the history revision system when creating new pages (thanks @tspivey for spotting this!)
  • Standardise line endings to \n (linux)
  • Enhanced setup instructions in README.
  • Long lines in code blocks now wrap correctly.
  • The export action now correctly includes uploaded files alongside their descriptions

v0.17.1

Fixed

  • Corrected default passwords. If you were having issues, try updating to this release, deleting peppermint.json and trying again (thanks for spotting this, @tspivey!)

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

  • [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.
  • [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!

  • Fixed that age-old warning in the search results if you have pages with special characters! I learnt a lot about utf8 whilst fixing this one.... (#114)

    • After visiting your wiki once, you'll be able to press <tab> when typing the path to your wiki to perform a search.

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 recent changes links a bit.
  • 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.
  • Linked pages with single quotes (') in their names correctly in page lists.
