111	111	A public ##org.xwiki.job.AbstractJob## (and corresponding ##AbstractJobStatus##) is now provided to help implementing a Job. An ##AbstractJob## class already existed since a long time but it was in an internal package.

	113	+== New lifespan LRU Cache setup ==
	114	+
	115	+It's now possible to define the maximum time to live since the entry is put in the cache. It used to be possible to set it only since the last time the value was used.
	116	+
	117	+{{code language="java"}}
	118	+// Configure cache eviction policy
	119	+LRUEvictionConfiguration lru = new LRUEvictionConfiguration();
	120	+// Set maximum size of the cache as 1000 entries
	121	+lru.setMaxEntries(1000);
	122	+// Set the maximum time to live since when the entry is used to 1 hour
	123	+lru.setMaxIdle(3600)
	124	+// Set the maximum time to live since when the entry is put in the cache to 1 hour
	125	+lru.setLifespan(3600)
	126	+{{/code}}
	127	+
	128	+[[Cache Macro>>extensions:Extension.Cache Macro]] and [[Rendering Cache>>platform:AdminGuide.Performances||anchor="HRenderingcache"]] are now based on this behavior.
	129	+
	130	+== VFS API ==
	131	+
	132	+{{warning}}
	133	+Right now the [[VFS API is missing authorization checks>>http://jira.xwiki.org/browse/XWIKI-12912]], meaning that you should use it only for public archives.
	134	+{{/warning}}
	135	+
	136	+Replacement of the [[Zip Explorer Plugin>>extensions:Extension.ZIP Explorer Plugin]]. API to access the content of archives files (zip, jar, gzip, tar, etc) located as attachments in wiki pages or elsewhere (external URLs, file system, et).
	137	+
	138	+In addition a new [[Velocity Tool>>extensions:Extension.Velocity Module||anchor="HVelocityTools"]] was added in order to be able to use a portion of the NIO2 API from Velocity: ##niotool##.
	139	+
	140	+See [[VFS API>>extensions:Extension.VFS API]] and [[VFS Tree Macro>>extensions:Extension.VFS Tree Macro]] for more details. Some API examples:
	141	+
	142	+{{code language="velocity"}}
	143	+{{velocity}}
	144	+## Get the URL to access the content of a file inside a zip:
	145	+[[link to file in zip>>$services.vfs.url("attach:Sandbox.WebHome@vma.txt.zip/vma.txt")]]
	146	+
	147	+## Display inline an image from a zip attached to a wiki page:
	148	+[[image:path:$services.vfs.url("attach:Sandbox.WebHome@test.zip/test.png")]]
	149	+
	150	+## Read the content of a file inside a zip attached to a page:
	151	+$stringtool.toString($niotool.readAllBytes("attach:Sandbox.WebHome@vma.txt.zip/vma.txt"), "utf-8")
	152	+
	153	+## List all entries inside a zip attached to a page:
	154	+#set ($dirStream = $niotool.newDirectoryStream("attach:Sandbox.WebHome@vma.txt.zip/"))
	155	+#foreach ($entry in $dirStream)
	156	+ * {{{$entry}}} - $niotool.isDirectory($entry)
	157	+#end
	158	+{{/velocity}}
	159	+
	160	+{{vfsTree root="attach:Sandbox.WebHome@vma.txt.zip/"/}}
	161	+{{/code}}
	162	+
	163	+Example of using the ##vfsTree## Macro:
	164	+
	165	+{{code language="none"}}
	166	+{{vfsTree root="attach:Sandbox.WebHome@vma.txt.zip/"/}}
	167	+{{/code}}

113	113	== Miscellaneous ==
114	114
115	115	* A new ##extractFirstReference(EntityType)## API has been added to ##EntityReference##: Extract the first entity of the given type from this one by traversing the current entity to the root. This differentiates it from ##extractReference(EntityType)## which extracts the last entity of the given type.

127	127	* Temporary resources can now be forced to be downloaded by using the ##force-download=1## URL parameter
	189	+* [[WebJars URL format>>extensions:Extension.WebJars Integration||anchor="HURLFormat"]] now supports a ##wiki## query string parameter to specify the wiki in which the webjars resource is available. For example: {{code language="none"}}/xwiki/webjars/AjaxQ/0.0.2/ajaxq.js?wiki=mywiki{{/code}}
	190	+* The default link behaviour can be disabled for a tree node, when you use the [[Tree Widget>>extensions:Extension.Tree Widget]], by using the 'jstree-no-link' CSS class on the node anchor, which can be set from the node JSON:(((

	210	+public List<List<RegexResult>> findAll(String content, String regex)

128	128
	213	+We had to add a new method because the existing ##RegexTool#find(String, String)## returns information about only the first capturing group. Here's a test to show how the new method works:
