Assemblies are separated into Microsoft.DocAsCode.Build, Microsoft.DocAsCode.DataContracts, and Microsoft.DocAsCode.Metadata namespace. All assemblies can be separately referenced through NuGet. In this way, it is much convenient for plugin writers to reference existing data models and utilities.

v1.6

1. Add attribute in c# and vb syntax.
2. Support full text search, with pure client side implementation:
   1. The feature is disabled by default. You can enable it by adding "_enableSearch": true to the globalMetadata property of docfx.json.

   3. --dryRun: if this option is set, docfx will go through all the build processes for all the documents, however, no documentation will generated.
2. Improve markdown:
   1. Allow paired parentheses in link target, e.g. [text](paired(parentheses(are)supported)now "title").

      1. similar to autolink: <xref:uid>
      2. similar to link: [title](xref:uid) or [title](@uid)

   3. support uid in toc.yml:

      - uid: getting-started
      - uid: manual

   4. support cross reference in toc.md

      # <xref:getting-started>
      # [Override title](@getting-started)

2. Update yaml serializion: Add @Microsoft.DocAsCode.YamlSerialization.ExtensibleMemberAttribute

3. Improve docfx init, now with docfx init, a docfx_project seed project will will generated.

4. Several improvements for default template:

   1. Provide properties to customize layout: _disableNavbar, _disableBreadcrumb, _disableToc, _disableAffix, _disableContribution, _disableFooter
   2. Include empty main.css and main.js to head.tmpl.partial partial template so that there is no need to customize head.tmpl.partial when you want to customize website style.

1. Fix cross domain issue: timeout exception throws when document build takes longer than 15 minutes
2. Fix docfx IOException when calling docfx -l report.txt

v1.3.5

FIX Github pages compatibility issue( Github pages now disallow iframe, however the default template of docfx uses iframe to load side toc): Update default template to use AJAX to load side toc, the original one is renamed to iframe.html. So now we have 2 embedded template, one is default and another is iframe.html.

v1.3

1. docfx improvements
   1. Add subcommand docfx template. You can now docfx template list and docfx template export -A to list and export all the embeded templates!
   2. Add subcommand docfx merge. You can use this subcommand to merge platform from multiple APIs with the same uid
   3. Add two options to build subcommand, --exportRawModel and --exportViewModel. --exportRawModel exports the data model to apply templates, --exportViewModel exports the view model after running template's pre-process scripts.
   4. Add --globalMetadata, and --globalMetadataFile options to build subcommand. These options allow globalMetadata to be loaded from command line in json format or from a JSON file.
   5. Add --fileMetadataFile option to build subcommand. This option allows fileMeatdata to be read from an external JSON file.
   6. Support plugins. You can create your own template with a plugins folder, inside which, you create your own build steps. Refer to @Microsoft.DocAsCode.EntityModel.Plugins.BaseDocumentBuildStep for a sample plugin implementation.

   2. Support query format in code snippet [!code-<language>[<name>](<codepath><queryoption><queryoptionvalue> "<title>")]
   3. Change xref logic:
      1. If content after @ is wrapped by ' or ", it contains any character including white space
      2. If content after @ is not wrapped by ' or ", it ends when:
         1. line ends
         2. meets whitespaces
         3. line ends with ., ,, ;, :, !, ? and ~
         4. meets 2 times or more ., ,, ;, :, !, ? and ~
3. Code improvements
   1. Add @Microsoft.DocAsCode.YamlSerialization This project is based on YamlDotNet. It overrides classes like type converters to improve performance and fix bug existed in YamlDotNet
   2. Refactor markdown engine @Microsoft.DocAsCode.MarkdownLite
   3. Add @Microsoft.DocAsCode.MarkdownLite.IMarkdownRewritable`1. It provides a way to operate markdown tokens.
4. Other improvements
   1. Add a new property _path into _attrs, it stands for the relative path from docfx.json to current file
   2. Improve missing xref warning message to include containing files.
   3. Add data-uid as attribute to generated html from default template, so that you can now find uid for API much more easily.

v1.2

1. Support Liquid template, templates ending with .liquid are considered as using liquid templating language. Liquid contains include tag to support partials, we follow the ruby partials naming convention to have _<partialName>.liquid as partial template. A custom tag ref, e.g. {% ref file1 %} is introduced to specify the resource files that current template depends on.
2. DFM include syntax is updated to use [!include[<title>](<filepath>)] syntax
3. Disable glob pattern in docfx metadata command line option as it is to some extent confusing, consider using a -g option later to re-enable it.

v1.1

1. Rewrite Glob The syntax of glob is:
   1. ** is called globstar, it matches any number of characters, including /, as long as it's the only thing in a path part.
   2. If ** is right behind /, it is a shortcut for **/*.
   3. * matches any number of characters, but not /
   4. ? matches 1 characters, but not /
   5. {} allows for a comma-separated list of "or" expressions, e.g. {a,b} => a and b
   6. ! at the beginning of a pattern will negate the match
   7. [...] matches a range of characters, similar to a RegExp range
   8. / is considered as path separator, while \ is considered as escape character
2. Support fileMetadata. You can specify different metadata value using glob pattern
3. Improve overwrite functionality. Now you can overwrite not only summary/remarks, but also descriptions for parameters. You can even add exceptions.
4. Now the latest project.json projects are also supported in DNX version.
5. Simple code snippet is now supported, syntax is [!code-REST-i[title](path "optionalTitle")]
