# 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

### Added
 - TODO Update the first-run wizard to ask whether people want the theme auto-updater to turned on because privacy and inadvertent requests to my web server
 - NOTE Don't forget to tell people how to turn the theme auto-updater off in this changelog
 - Added automatic dark mode to default theme using `prefers-color-scheme`

### Fixed
 - Fixed a bug in the search query performance metrics
 - Fill out the statistics help text
 - Added table of contents to help page
 - Squashed the large blank space that appears at the bottom of the page editor page when editing long pages
 - Accessibility improvements - thanks, Firefox developer tools :D (if you're a screen reader / accessibility tool user and have feedback or any better ideas, please [get in touch](https://github.com/sbrl/Pepperminty-Wiki/issues/new))
     - Marked the user avatar on the top navigation bar as hidden for screen readers
     - Added aria label to user preferences button
     - Hide site logo from screen readers
 - Lists of pages that have a specific tag will now be sorted alphabetically (Unicode characters should be handled correctly too)
 - Support Unicode characters when sorting. If it's a list of something, then it's now sorted correctly (e.g. includes pages, tags, etc).
 - Squashed a bunch of warnings about a non-static method in the page renderer
 - Fixed a warning message in the `peppermint.json` access checker
 - Fixed footnote rendering (thanks again, @SeanFromIT!)

### Changed
 - Made `build.sh` build script more robust, especially when generating the documentation.
 - Vastly improved search engine performance
     - A new SQLite-based index format is now used, so search indexes will need to be rebuilt (migrating would probably take longer than a rebuild :-/)
 - New search query syntax
 - When making remote requests, Pepperminty Wiki will now correctly set the user agent string
     - The server's `expose_php` setting is respected - if it's disabled, then the PHP version will not be exposed.
     - Pepperminty Wiki _shouldn't_ make remote requests without you asking it to - see above and the theme gallery
 - Improved peppermint.json.compromised error message - if it's still unclear, please let me know
 - Fiddled with the extra data extractor, as it seems that some people were experiencing strange issues with `stream_get_meta_data()`


## v0.19.4-hotfix4
 - Fixed page revision id incrementing if you don't have a page called `history` on your wiki (thanks @SeanFromIT!)


## v0.19.3-hotfix3
 - Improve error messages in the extra data unpacker
 - Change the extra data unpacker to us  `tempnam()` instead of `tmpfile()`, since some people appeared to be having issues with the other approach
 - Squash a deprecation warning caused by a typo (thanks, @SeanFromIT!)


## v0.19.2-hotfix2
 - Patched another crazy bug in the extra data system in the downloader


## v0.19.1-hotfix1
 - Patched [the downloader](https://starbeamrainbowlabs.com/labs/peppermint/download.php) which was throwing warnings when packing downloads


## 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();`](https://devdocs.io/php/function.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](https://gitlab.com/sbrl/nightdocs) instead of [docpress](https://docpress.github.io/) (the [official docs](https://starbeamrainbowlabs.com/labs/peppermint/_docpress/) will update & change URL on the next stable release)
 - Add moar [badges](https://shields.io/) 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](https://starbeamrainbowlabs.com/labs/peppermint/_docpress/)
 - 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
 - [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](https://www.smashingmagazine.com/2017/04/guide-http2-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](https://starbeamrainbowlabs.com/labs/peppermint/peppermint-config-info.php) (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](https://www.random.org/).
     - The PHP function `openssl_pseudo_random_bytes()` was being used before, but [apparently that's not cryptographically secure](https://paragonie.com/blog/2015/07/how-safely-generate-random-strings-and-integers-in-php).
 - [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!

 - [Rest API] Added `format` parameter to `recentchanges` action
 - [Rest API] Added `comments-fetch` action to return a page's comments as JSON

 - Fixed image captions in some cases (let me know if you still get warnings)
 - Squashed warnings when you do a search with a forward slash (`/`) in your query
 - 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)
     - You'll need to rebuild your search index for this fix to fully take effect (call the `invindex-rebuild` action as a mod or better)

## v0.14

### Changed
 - Improve the look of the downloader a bit. More work is needed here, apparently - I haven't touched it in _ages_!

## v0.14-beta1

### Added
 - Commenting! You'll need to update any custom themes you've created if you're including the commenting module in your build.
 - Added stacked bar to help you visualise what's taking up all the space in your wiki
 - Added link to edit master settings in the credits
 - Initial open search support!
     - After visiting your wiki once, you'll be able to press `<tab>` when typing the path to your wiki to perform a search.
     - It'll only work if your wiki is at the top-level of a domain without _anything_ after the `/` (subdomains are ok). This is a restriction of the protocol, not Pepperminty Wiki!

 - PR #135: Fix repeated page names on sidebar by @ikisler
 - PR #136: Fix issue where bottom nav is cut off by @ikisler

## 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
 - Don't search page titles or tags for stop words - it skews results since we don't search the page body for them


## 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.
 - Fixed blank descriptions in search results by defaulting to a snippet from the beginning of the page.
