**Note:** This changelog only provides basic information about the enormous
changes introduced with Pico 1.0.0-beta.1. Please refer to the
UGPRADE section of the docs for details.
```
* [Security] (9e2604a) Prevent content_dir breakouts using malicious URLs
* [New] Pico is on its way to its first stable release!
* [New] Provide pre-bundled releases
* [New] Heavily expanded documentation (inline code docs, user docs, dev docs)
* [New] New routing system using the QUERY_STRING method; Pico now works
out-of-the-box with any webserver and without URL rewriting; use
`%base_url%?sub/page` in markdown files and `{{ "sub/page"|link }}`
in Twig templates to declare internal links
* [New] Brand new plugin system with dependencies (see `PicoPluginInterface`
and `AbstractPicoPlugin`); if you're plugin dev, you really should
take a look at the UPGRADE section of the docs!
* [New] Introducing the `PicoDeprecated` plugin to maintain full backward
compatibility with Pico 0.9 and Pico 0.8
* [New] Support YAML-style meta header comments (`---`)
* [New] Various new placeholders to use in content files (e.g. `%site_title%`)
* [New] Provide access to all meta headers in content files (`%meta.*%`)
* [New] Provide access to meta headers in `$page` arrays (`$page['meta']`)
* [New] The file extension of content files is now configurable
* [New] Add `Pico::setConfig()` method to predefine config variables
* [New] Supporting per-directory `404.md` files
* [New] #103: Providing access to `sub.md` even when the `sub` directory
exists, provided that there is no `sub/index.md`
* [New] #249: Support the `.twig` file extension for templates
* [New] #268, 269: Now using Travis CI; performing basic code tests and
implementing an automatic release process
* [Changed] Complete code refactoring
* [Changed] Source code now follows PSR code styling
* [Changed] Replacing constants (e.g. `ROOT_DIR`) with constructor parameters
* [Changed] Paths (e.g. `content_dir`) are now relative to Pico's root dir
* [Changed] Adding `Pico::run()` method that performs Pico's processing and
returns the rendered contents
* [Changed] Renaming all plugin events; adding some new events
* [Changed] `Pico_Plugin` is now the fully documented `DummyPlugin`
* [Changed] Meta data must start on the first line of the file now
* [Changed] Dropping the need to register meta headers for the convenience of
users and pure (!) theme devs; plugin devs are still REQUIRED to
register their meta headers during `onMetaHeaders`
* [Changed] Exclude inaccessible files from pages list
* [Changed] With alphabetical order, index files (e.g. `sub/index.md`) are
now always placed before their sub pages (e.g. `sub/foo.md`)
* [Changed] Pico requires PHP >= 5.3.6 (due to `erusev/parsedown-extra`)
* [Changed] Pico now implicitly uses a existing `content` directory without
the need to configure this in the `config/config.php` explicitly
* [Changed] Composer: Require a v0.7 release of `erusev/parsedown-extra`
* [Changed] #93, #158: Pico doesn't parse all content files anymore; moved to
`PicoParsePagesContent` plugin, but still impacts performance;
Note: This means `$page['content']` isn't available anymore, but
usually the new `$page['raw_content']` is suitable as replacement.
* [Changed] #116: Parse meta headers using the Symfony YAML component
* [Changed] #244: Replace opendir() with scandir()
* [Changed] #246: Move `config.php` to `config/` directory
* [Changed] #253: Assume HTTPS if page is requested through port 443
* [Changed] A vast number of small improvements and changes...
* [Fixed] Sorting by date now uses timestamps and works as expected
* [Fixed] Fixing `$currentPage`, `$nextPage` and `$previousPage`
* [Fixed] #99: Support content filenames with spaces
* [Fixed] #140, #241: Use file paths as page identifiers rather than titles
* [Fixed] #248: Always set a timezone; adding `$config['timezone']` option
* [Fixed] A vast number of small bugs...
* [Removed] Removing the default Twig cache dir
* [Removed] Removing various empty `index.html` files
* [Removed] Moving Pico's excerpt feature to `PicoExcerpt` plugin

As pointed out by @Lomanic (see https://github.com/picocms/Pico/pull/260#issuecomment-153091890; thank you btw\!) we actually have to explain users how to change the content directory. This runs contrary to our "stupidly simple" claim. So Pico now simply uses the `content` directory when it exists...
This was dropped without a replacement with Pico 0.9. I checked all changes since Pico 0.8 manually, as far as I can tell there should be no more surprises regarding BC... Thanks @Lomanic for rubbing our nose in the fact that we should check this! I also added the missing changes of Pico 0.9 to changelog.txt
I always thought that doing this is pretty unusual... But now it simply breaks BC - please refer to @Lomanic's [comment](https://github.com/picocms/Pico/pull/260#issuecomment-152610857). Using a return statement has no advantages, but increases the probability that something goes wrong (e.g. a clueless user removes the return statement). It was introduced with 23b90e2, but we never released it ([v0.9.1](4cb2b24fae/lib/pico.php (L188-L189))). Removing the return statement shouldn't cause any problems even for users which installed Pico in the meantime. As a result we don't break BC and moreover remove a prior BC break 😃
According to travis-ci/travis-ci#2111 and some own testing, it isn't possible to combine branch whitelists with tag-based auto deployment. Unfortunately it is necessary to whitelist the gh-pages branch, because Travis implicitly blacklists it.
