Welcome to the Zend Framework 1.11 Release! 



RELEASE INFORMATION

---------------

Zend Framework 1.11.2 Release (r23587).

Released on  , .



NEW FEATURES

------------



Mobile Support:



    Zend Framework 1.11 marks the first release with explicit support

    for mobile devices, via the new component Zend_Http_UserAgent. This

    component was developed by Raphael Carles, CTO of Interakting.

    

    Zend_Http_UserAgent performs two responsibilities:

    

     * User-Agent detection

     * Device capabilities detection, based on User-Agent

    

    The component includes a "features" adapter mechanism that allows

    developers to tie into different backends for the purpose of

    discovering device capabilities. Currently, ships with adapters for

    the WURFL (Wireless Universal Resource File) API, TeraWURFL, and

    DeviceAtlas.

    

     * Note: Luca Passani, author and lead of the WURFL project, has

       provided an exemption to Zend Framework to provide a non-GPL

       adapter accessing the WURFL PHP API.

    

    Additional hooks into the component are provided via a

    Zend_Application resource plugin, and a Zend_View helper, allowing

    developers the ability to return output customized for the detected

    device (e.g., alternate layouts, alternate images, Flash versus

    HTML5 support, etc.).



Zend_Cloud: SimpleCloud API:



    During ZendCon 2009, Zend announced a prototype of the SimpleCloud

    API. This API was to provide hooks into cloud-based document

    storage, queue services, and file storage.



    Zend Framework 1.11.0 markes the first official, stable release of

    Zend_Cloud, Zend Framework's PHP version of the SimpleCloud API.

    Current support includes:



    * Document Services:

      - Amazon SimpleDB

      - Windows Azure's Table Storage

    * Queue Services:

      - Amazon Simple Queue Service (SQS)

      - Windows Azure's Queue Service

      - All adapters supported by Zend_Queue:

        * Zend Platform JobQueue

        * Memcacheq

        * Relational Database

        * ActiveMQ

    * Storage Services:

      - Amazon Simple Storage Service (S3)

      - Windows Azure's Blog Storage

      - Nirvanix

      - Local filesystem



    When using any of the SimpleCloud APIs, your code will be portable

    across the various adapters provided, allowing you to pick and

    choose your services, as well as try different services until you

    find one that suits your application or business needs.

    Additionally, if you find you need to code adapter-specific

    features, you can drop down to the specific adapter in order to do

    so.



    More adapters will be arriving in the coming months, giving you even

    more options!



    We thank Wil Sinclair and Stas Malyshev for their assistance in the

    initial releases of Zend_Cloud.



Security:



    Several classes in Zend Framework were patched to eliminate the

    potential for leaking timing information from the direct comparison

    of sensitive data such as plaintext passwords or cryptographic

    signatures to user input. These leaks arise from the normal process

    of comparing any two strings in PHP. The nature of the leaks is that

    strings are often compared byte by byte, with a negative result

    being returned early as soon as any set of non-matching bytes is

    detected. The more bytes that are equal (starting from the first

    byte) between both sides of the comparison, the longer it takes for

    a final result to be returned. Based on the time it takes to return

    a negative or positive result, it is possible that an attacker

    could, over many samples of requests, craft a string that compares

    positively to another secret string value known only to a target

    server simply by guessing the string one byte at a time and

    measuring each guess' execution time. This server secret could be a

    plaintext password or the correct cryptographic signature of a

    request the attacker wants to execute, such as is used in several

    open protocols including OpenID and OAuth. This could obviously

    enable an attacker to gain sufficient information to perform a

    secondary attack such as masquerading as an authenticated user.



    This form of attack is known as a Remote Timing Attack. Timing

    Attacks have been problematic in the past but to date have been very

    difficult to perform remotely over the internet due to the

    interference of network jitter which limits their effectiveness in

    resolving very small timing differences. While the internet still

    poses a challenge to performing successful Timing Attacks against a

    remote server, the increasing use of frameworks on local networks

    and in cloud computing, where network jitter may be significantly

    reduced, raises the distinct possibility that remote Timing Attacks

    will become feasible against ever smaller timing information leaks,

    such as those leaked when comparing any two strings. As a

    precaution, the applied changes implement a fixed time comparison

    for several classes which would be attractive targets in any

    potential remote Timing Attack. A fixed time comparison function

    does not leak any timing information useful to an attacker thus

    proactively preventing any future vulnerability to these forms of

    attack.



    We thank Padraic Brady for his efforts in identifying and patching

    these vulnerabilities.



SimpleDB Support:



    Zend Framework has provided support for Amazon's Simple Storage

    Service (S3), Simple Queue Service (SQS), and Elastic Cloud Compute

    (EC2) platforms for several releases. Zend Framework 1.11.0 adds

    support for SimpleDB, Amazon's non-relational document storage

    database offering. Support is available for all SimpleDB operations

    via Zend_Service_Amazon_SimpleDb.

    

    Zend Framework's SimpleDB adapter was originally written by Wil

    Sinclair.



eBay Findings API Support:



    eBay has an extensive REST API, allowing developers to build

    applications interacting with their extensive data. Zend Framework

    1.11.0 includes Zend_Service_Ebay_Findings, which provides complete

    support for the eBay Findings API. This API allows developers to

    query eBay for details on active auctions, using categories or

    keywords.



    Zend_Service_Ebay was contributed by Renan de Lima and Ramon

    Henrique Ornelas.



New Configuration Formats:



    Zend_Config has been a quite popular component in Zend Framework,

    and has offerred adapters for PHP arrays, XML, and INI configuration

    files. Zend Framework 1.11.0 now offers two additional configuration

    formats: YAML and JSON.



    Zend_Config_Yaml provides a very rudimentary YAML-parser that should

    work with most configuration formats. However, it also allows you to

    specify an alternate YAML parser if desired, allowing you to lever

    tools such as PECL's ext/syck or Symfony's YAML component, sfYaml.



    Zend_Config_Json leverages the Zend_Json component, and by extension

    ext/json.



    Both adapters have support for PHP constants, as well as provide the

    ability to write configuration files based on configuration objects.



    Stas Malyshev created both adapters for Zend Framework;

    Zend_Config_Json also had assistance from Sudheer Satyanarayana.



URL Shortening:



    Zend_Service_ShortUrl was added for this release. The component

    provides a simple interface for use with most URL shortening

    services, defining simply the methods "shorten" and "unshorten".

    Adapters for the services http://is.gd, http://jdem.cz,

    http://metamark.net, and http://tinyurl.com, are provided with this

    release. 



    Zend_Service_ShortUrl was contributed by Martin Hujer.



Additional View Helpers:



    Several new view helpers are now exposed:



    * Zend_View_Helper_UserAgent ties into the Zend_Http_UserAgent

      component, detailed above. It gives you access to the UserAgent

      instance, allowing you to query for the device and capabilities.

    * Zend_View_Helper_TinySrc is an additional portion of Zend

      Framework's mobile offering for version 1.11.0. The helper ties

      into the TinySrc API, allowing you to a) provide device-specific

      image sizes and formats for your site, and b) offload generation

      of those images to this third-party service. The helper creates

      img tags pointing to the service, and provides options for

      specifying adaptive sizing and formats.

    * Zend_View_Helper_Gravatar ties into the Gravatar API, allowing you

      to provide avatar images for registered users that utilize the

      Gravatar service. This helper was contributed by Marcin Morawski.
