For Developers

Elasticsearch Integration to the Core Distribution

Previously distributed as an additional package, Elasticsearch is integrated to the core distribution. By default it starts in an embedded mode, and can also be configured so as to dialog with an external Elasticsearch cluster. All documents are indexed with Elasticsearch. It is possible to disable the service. Only Search tab leverages Elasticsearch index in the default distribution, but you can activate it on any page provider by modifying a property in nuxeo.conf, ex:

elasticsearch.override.pageproviders=default_search,tree_children

Audit Service Based on Elasticsearch

A new implementation of the audit service has been made on top of an elastic search index. This provides greater performances which was necessary when audit has millions of entries, and more power in terms of defining what fields are stored.

Support of Facets and Other Kind of Aggregates on Page Providers and Content Views

Page Provider now integrates aggregates support and content view leveraging such kind of page providers can be configured via Nuxeo Studio easily. That way you can build search interfaces with terms, ranges and histograms filters. Many use cases have been taken into account: support of dates, specific widgets for users, directories, documents.

New Download Servlet

A new download servlet is available for documents that are not bound to a specific document. This new servlet is used by the Download File operation so as to get this operation working even with big files.

Collection Synchronisation

You can synchronize collections with Drive. Feature is not yet enabled for the user by default. You still need to add the action by contribution, as we are experimenting the feature before making it generally available.

REST API

ParentId Ref

parentRef id has been added to the json response.

Use Elasticsearch index on Query Endpoint

The query endpoint now uses a named page provider who can be configured to hit Elastiscsearch index.

Parameters for Content Enricher contribution

Content enricher extension point now accepts parameters. Some new content enricher classes were added that makes use of this new capability: UserPermissions and Vocabulary.


<enricher name="permissions" class="org.nuxeo.ecm.automation.io.services.enricher.UserPermissionsContentEnricher" >
<category>permissions</category>
<parameter name="permissions">Read,Write,Everything</parameter>

</enricher>

CMIS Implementation Evolutions

ACLs are now implemented
Rendition filters
ecm:pos is exposed in CMISQL, so as to handle correctly ordered folders

Automation: Execution Flow Operations

The list of operations allowing to launch other chains for loops (loop on blobs, loop on documents, loop on arbitrary lists) has been cleaned up. Idea is to have on all those operations support for transaction management, so as to be able to easily design scalable and robusts automation chains.

JSF2

Content Application Platform (CAP) and all the plugins have been migrated from JSF 1.2 to JSF 2 and the latest stable release of Richfaces: 4.5. A migration tool has been implemented for helping you migrate your custom code base. That will be necessary when you plan to upgrade your Nuxeo Platform instance to 6.0.

Improvement of Content Views Configurability

You can now control the display of the slideshow , the spreadsheet and the edit columns menu at the result layout level. Even better, this area is now a category of action that has access to the content view and properties configured in it for displaying it.

Typed Layout

Layouts now have a type, which allows to define properties that can be used to define on a per instance basis if some given features are supported. We currently use it for result layouts, with two types: listingTable and listingThumbnail

Widget Definition Alias

It is possible to define aliases for a widget definition, so as to override former widget definitions with a newer one without having to duplicate that definition. Ex: - document_listing_ajax -> table_listing - search_listing_ajax -> table_listing

documentMode with Fallback on Toggleable layouts widget

Toggleable document layout widget now handles a document mode, since modes for documents are not restricted to "create" or "edit" or "view" and can gather layouts for different rendering use cases (like the drive edit screen), and still need to use "edit" or "view" mode for render. Furthermore, a logic of fallback has been added when the given mode has not been contributed.

Dev Mode: Display of Page Structure

In Development mode, you can display the structure of your page : layouts, widgets, actions, just select the object and display its properties. This makes it a great tool for getting inspiration from the default application for your own project.

Multi-navigation Category of Actions

The placeholder for adding virtual navigations is now part of Nuxeo CAP. You don’t need to depend of Virtual navigation for adding elements there.

Custom Headers in the Webapp

A custom header has been added: "X-UA-Compatible" with the value "IE=10; IE=11" so as to better control behaviour on Internet Explorer on supported versions. The way this header has been added benefits from a new extension point that allows to contribute additionnal headers.

UserWorkspace Improvements

It is now possible to override the behaviour of user workspace creation.

Incremental Update for Integer fields

Some document fields can now be updated at the storage level using atomic increment/decrement operations. This is needed for instance to allow concurrent delta updates of fields without losing information. A typical use case is the quotas. See http://jira.nuxeo.com/browse/NXP-15103 for more details.

Directory Low Level Access Restriction

When contributing a directory declaration, it is now possible to add READ and WRITE restrictions to specific groups.

Configure Mail Creation with Automation

The Nuxeo Platform Mail module has been moved out of the default product and now lives as a marketplace package called "Nuxeo Imap Connector". Additionnaly, its configurability has been improved as there is now a way to customise the mail creation logic just using an automation chain.

Changes in Features Layout

There were some big changes in the way features are distributed. Nuxeo DM is a deprecated assembly. You shoud now start systematically from Nuxeo CAP and add addition packages. Faceted Search has been deprecated and exists as a separated package. Virtual Navigation is in a separated package. Tags support has been integrated to Nuxeo CAP. Open Social is deprecated and exits now in a separate marektplace pacakge. DAM package contains all the imaging-* addons, and brings Picture, Video and Sound types.
