# Changes in version 0.5

The main change with this release is that generating a site will cause errors whenever more than one post or draft would generate to the same URL. You can see more about this at https://github.com/aprescott/serif/pull/47 .

This release contains a breaking change: `page.title` in templates is now a single string value, instead of an array of strings. If you were previously using this in your templates:

    {{ page.title | join: " - " }}

you should replace this with:

    {{ page.title }}

`page.title` was previously a single-element array on all pages except for individual posts, when it was

    [ "Posts", post.title ]

For such pages, it is now simply `post.title`. If you were relying on the value of "Posts" being present in `page.title` for post pages, you should instead use the new `post_page` template variables. See: https://github.com/aprescott/serif#template-variables

Summary:

* Site generation will be blocked if any two posts or drafts lead to the same URL. (#47)

* Bookmark links are generated with JavaScript instead of trying to detect Rack environment variables, which is buggy with some SSL configurations. (#52)

* `page.title` is now a single value, instead of being an array. (#45)

* `post_page` flag added for use in templates. Set to true when generating a post. (#45)

* Better README documentation for headers and per-post permalinks. (#46)

* `serif` with no arguments or `-h` or `--help` will now show usage. (#44)
