##### org.apache.juneau

- PojoQuery improvements.
- New RemoteMethod.returns() annotation.
  Allows you to specify whether the remote method returns the HTTP body or status code.
- Fixed bugs with BEAN_includeProperties and BEAN_excludeProperties settings.
- New/modified settings in HtmlDocSerializerContext:
  - HTMLDOC_script
  - HTMLDOC_style - Was HTMLDOC_css.
  - HTMLDOC_stylesheet - Was HTMLDOC_cssUrl. Now an array.
- New ResourceFinderutility class. Allows you to search for resources up the parent hierarchy chain. Also allows you to search for localized resources.
- Eliminated the following properties from HtmlDocSerializerContext: HTMLDOC_title, HTMLDOC_description, HTMLDOC_description
  See below on changes to simplify HTML headers.
- {@link oaj.svl.Var} implementations can now throw exceptions and will be converted to ""{exceptionMessage}" values.

##### org.apache.juneau.rest

- New 'light' stylesheet:
  Compared with previous 'devops':
  For those nolstalgic for old times, there's also 'original':
- Simplified the stylesheets and HTML code.
  For example, the nav links are now an ordered list of elements which makes rendering as as side-bar (for example) easier to do in CSS.
- Modifications to the following @HtmlDoc annotations:
  - HtmlDoc.navlinks() navlinks()- Now an array of strings instead of a JSON object. Simplified syntax.
    For example:

    // Old syntax htmldoc=@HtmlDoc( links="{" + "up:'request:/..'," + "options:'servlet:/?method=OPTIONS'," + "contentTypes:'$W{ContentTypeMenuItem}'," + "styles:'$W{StyleMenuItem}'," + "source:'$C{Source/gitHub}/org/apache/juneau/examples/rest/PetStoreResource.java'" + "}" ) // New syntax htmldoc=@HtmlDoc( navlinks={ "up: request:/..", "options: servlet:/?method=OPTIONS", "$W{ContentTypeMenuItem}", "$W{StyleMenuItem}", "source: $C{Source/gitHub}/org/apache/juneau/examples/rest/PetStoreResource.java" } )

    Previous syntax will still work but you're encouraged to use the simplified syntax.
  - Several annotations are now arrays of strings instead of simple strings. Values are simply concatenated with newlines which makes multi-line values cleaner.
    - HtmlDoc.header() header()
    - HtmlDoc.nav() nav()
    - HtmlDoc.aside() aside()
    - HtmlDoc.footer() footer()
    - HtmlDoc.script() script()
    - HtmlDoc.style() style()
    Additionally, the "INHERIT" string literal can be used to combine the value with the value defined on the servlet or parent class. Links can also be inserted at specific index positions.
- Improvements made to the {@link oajr.widget.Widget} API.
  - You can now add arbitrary CSS and Javascript along with your widgets through new methods:
    - Widget.getHtml(RestRequest)
    - Widget.getScript(RestRequest)
    - Widget.getStyle(RestRequest)
  - Declaration of widgets moved to HtmlDoc.widgets() @HtmlDoc(widgets) instead of separately on @RestResourceand @RestMethod annotations.
  - {@link oajr.widget.Widget#getName()} now defaults to the simple class name.
    So now you can just refer to the class name: "$W{ContentTypeMenuItem}".
  - Renamed widgets:
    - PoweredByApacheWidget -> PoweredByApache
    - PoweredByJuneauWidget -> PoweredByJuneau
  - New {@link oajr.widget.MenuItemWidget} can be used as a starting point for creatint pull-down menu items.
  - New {@link oajr.widget.ContentTypeMenuItem} widget that provides a pull-down menu with hyperlinks for all supported languages for that page:
  - Improved {@link oajr.widget.QueryMenuItem} widget that provides a pull-down menu of a search/view/order-by/page form:
    Fields are now pre-filled with current query parameters.
  - New {@link oajr.widget.ThemeMenuItem} widget that provides a pull-down menu with hyperlinks to show the content in the default stylesheets:
- New/modified annotations on HtmlDoc @HtmlDoc:
  - HtmlDoc.style() style()- Renamed from css().
  - HtmlDoc.stylesheet() stylesheet()- Renamed from cssUrl().
    Can now be a comma-delimited list of URLs.
  - HtmlDoc.script() script()- Add arbitrary Javascript to page header.
- Bug fix with HtmlDoc.nowrap() @HtmlDoc(nowrap)so that the setting only applies to the data contents, not the whole page.
- Two convenience methods added to {@link oajr.RestRequest}:
  - RestRequest.attr(String,Object)
  - RestRequest.prop(String,Object)
- Annotations added:
  - @RestResource(siteName)
  - @RestResource(flags)
  - RestMethod.flags() @RestMethod(flags)
- Eliminated the @RestResource(stylesheet)annotation. It's no longer needed now that you can easily specify styles via @Htmldoc.
- Eliminated the following annotations since they are now redundant with HtmlDoc.header() @HtmlDoc(header):
  - title()
  - description()
  - branding()
  Instead, the BasicRestServletclass defines the following default header that can be easily overridden:

  htmldoc=@HtmlDoc( header={ "<h1>$R{resourceTitle}</h1>", "<h2>$R{methodSummary,resourceDescription}</h2>", "<a href='http://juneau.apache.org'><img src='$U{servlet:/htdocs/juneau.png}' style='position:absolute;top:5;right:5;background-color:transparent;height:30px'/></a>" } )

  Note that the subtitle first tries using the method summary and then the servlet description.
- New {@link oajr.vars.FileVar $F} variable resolver for resolving the contents of files in the classpath.
  The DockerRegistryResource examples shows how it can be used to pull in a localized file from the classpath to populate the aside section of a page.

  htmldoc=@HtmlDoc( // Pull in aside contents from file. aside="$F{resources/DockerRegistryResourceAside.html}" )

- New ReaderResource.toCommentStrippedString()method.
- The bpIncludes() and bpExcludes() annotations on @RestMethod has been replaced with the following:
  - RestMethod.bpi() bpi()- Now an array of simplified values instead of LAX JSON.
  - RestMethod.bpx() bpx()- Now an array of simplified values instead of LAX JSON.
- Two new variables added to $R variable: "$R{servletClass}", "$R{servletClassSimple}"

##### org.apache.juneau.rest.examples

- Added CONTENT-TYPE and STYLES menu items to most pages.
- Added improved QUERY menu item to PetStore page.
