消息：Deer Park Alpha 1 Available [一点说明by 斑竹]

最新的Nightly Trunk版本（newer than 20050504）开始采用Opera的前进、后退机理， 当你点击这两个按钮的时候，FX将直接还原Cache里的内容，速度应该会和Opera的cache载入一样，非常快了。
这些更新将会在FX 1.1发布版里出现
本改变默认是关闭的，要打开的话：
在about:config里新建一个整型变量
名称为： browser.sessionhistory.max_viewers
键值为: 5 (或者任何非零的整数)
重启Firefox.

Note这不会在Firefox 1.0.x的nightly或者是将来的release版本中出现，而且作为一个major改变，可能会有bug. 到这里汇报： https://bugzilla.mozilla.org/enter_bug.cgi?product=Core

Note2:如果你要尝试FX trunk nightly，我建议下载zip版本，并且不要覆盖你的稳定版本，让两个共存，因为trunk的nightly版本几乎不兼容大部分的扩展。如果你要退回稳定版，直接删除解压缩的文件夹即可。

对于终端用户：
General

"Sanitize" privacy feature
    The "Sanitize" feature provides an easy way to quickly remove browsing history, cookies, cache, saved form information, and other personal data. The items to be removed can be customized, and the feature can be activated using either a keyboard shortcut or through a menu item.
Image thumbnails as tab icons
    When viewing images, tab icons now display thumbnails of the displayed image.
Fast back (and forward)
    This very experimental feature allows much faster session history navigation. The feature is off by default but can be enabled for testing purposes by setting the browser.sessionhistory.max_viewers preference to a nonzero number.
Anonymous FTP login failure behavior
    FTP users are now prompted to input a name and password if anonymous access fails.
CSS at-rule for matching on site/document URL
    The new @-moz-document rule gives users the ability to match page objects per-site, using CSS. This makes it possible to include site-specific rules in user style sheets (userContent.css). David Baron's post to www-style explains how the rule can be used.
Report a broken website wizard
    Users now have a simple tool for reporting websites that aren't working in Firefox. If installed (Reporter is a custom install option for this release) the tool can be accessed from "Report Broken Website" on the Firefox Help menu.

Improved Preferences

Instant Apply behavior on Linux and Mac
    Changes made in the Preferences window now apply immediately, in line with typical behavior in other Mac OS X and GNOME applications. This changes conforms with the Apple and GNOME Human Interface Guidelines.
Searchable download actions manager
    You are now able to search through Firefox's file associations for downloaded files by program name or their file extension.
Searchable cookie manager
    Cookies can be searched by hostname/domain and cookie name, and are organized by hostname in a tree format instead of a flat list.

Deployment

Support for profile "temp" directory on local filesystem
    It is now possible to store the network cache (copies of visited webpages) and the XUL fastload cache (precompiled user interface code) on a local disk, while keeping the rest of the profile data on a network drive. This will increase performance and reduce network traffic for users in a network environment.

Mac OS X Support

Accessibility
    Supports "Full Keyboard Access" system setting.
Drag and drop
    Users can now drag more file types to the Dock icon to open in the browser.
Menus
    Menus function properly in windows without special menus and with no windows open.
Mouse Actions
    Middle mouse buttons now function as expected.
Keyboard shortcuts
    Cmd+Return and Cmd+Shift+Return are now supported for address completion as on other platforms.
    Back, Forward, Stop and Help keyboard shortcuts are now exposed.

对于网络开发人员：
HTML

Elements with tabindex="-1" should be focusable
    Elements with a negative tabindex attribute can now have focus, even though they are not in the tab order.
Object should submit
    In accordance with the HTML4 specification, <object> elements can now be submitted as part of a form.

CSS

CSS2 quotes nesting
    Starting with this release, the CSS2 quotes property is fully supported, with the correct quote (depending on the nesting level) being used for open-quote and close-quote.
CSS3 nly-child
    This CSS3 selector allows selecting an element that has no other elements as siblings in the DOM.
CSS3 columns
    An experimental implementation of the proposed CSS3 multicolumn layout draft. This allows easily doing newspaper-like multicolumn presentation.
CSS3 overflow-x and overflow-y properties
    These properties can be used to control the overflow behavior in the horizontal and vertical directions somewhat independently. For example, overflow in the horizontal direction could be hidden while overflow in the vertical direction can be scrolled to.
CSS3 cursors
    More mouse cursor names are now supported.
URI values on CSS cursor properties
    On Windows, OS/2 and Linux (Gtk+ 2.x) one can now use an arbitrary image as the mouse cursor while a given DOM node is being hovered. Any image format supported by Gecko can be used for the image (SVG, animated GIF, and ANI cursors are not supported).
CSS outline property
    CSS outlines can now be used. These differ from borders in that they don't affect the page layout.
-moz-outline-radius
    CSS outlines can now have rounded corners.
Counters in CSS-generated content
    CSS2 counters are now completely supported (the implementation doesn't match the current CSS2.1 draft, but matches the upcoming one). This allows automatic numbering of sections, headings, and so forth via stylesheets.

JavaScript and DOM

Array extras
    New methods have been added to the Array object to facilitate common tasks. See JavaScript 1.5 Array Object.
document.open("text/plain")
    Text written in new documents created with document.open("text/plain") is now treated as text rather than HTML, so line breaks will remain intact and tags will not be parsed.
XML Events
    "XML Events" is a W3C specification to provide XML languages with the ability to integrate declarative event listeners and event handlers.
Canceling keydown
    Canceling the keydown event now properly cancels any corresponding keyup/keypress events, per the DOM specification.
Accessibility APIs for DHTML
    Mozilla now allows DHTML authors to add role and state semantics to custom elements, and exposes that information via MSAA and ATK.
DHTML Performance Fixes
    A number of changes were made to significantly improve DHTML speed and smoothness.

Graphics

SVG Support
    SVG is W3C specification providing resolution-independent scalable vector graphics, along with a DOM. A technology preview of native SVG support is included in this release. Currently a subset of SVG 1.1 Full, missing functionality includes filters, declarative animation, and SVG defined fonts.
Canvas Support
    <canvas> is a scriptable bitmap drawing surface. It is suitable for many uses, such as adding graphs to interactive DHTML and drawing game graphics. For a further introduction, see Drawing Graphics with Canvas.

Miscellaneous

Support HTTP/1.1 408 response code
    A persistent connection is now correctly closed when a 408 response code (Request timeout) is received. The request is retried in a new connection.
URIs always sent as UTF8
    URIs are now always sent to the server as UTF8, regardless of the linking page's encoding. This fixes images and links on sites with non-ASCII filenames.
XForms support
    The W3C's XML Forms language allows writing complex forms in XML, and includes features that regular HTML forms do not have, such as client side validation against XML Schema and XML submission/retrieval. Support for XForms comes as an extension, see Mozilla XForms Project Page.

对于扩展程序开发人员：

New Extension Developer Features in Deer Park Alpha 1

These items can be leveraged by extension developers building on top of Deer Park Alpha 1 and other new Mozilla applications.

Hidden referrer column for history
    Extensions can now access the referrer information for pages stored in the browser history. This feature can be used to provide alternate history views and other useful functionality.
API for prioritizing HTTP connections
    The Mozilla networking library now supports the prioritization of connections to a specific server. (details)
API for managing user and UA stylesheets
    Extensions can now register stylesheet URIs as additional user and UA stylesheets. This means extensions no longer have to try to edit userContent.css to add styling (say for XBL binding attachment) to web pages. For details on using this API, see Using the Stylesheet Service.
API for configuring proxies
    It is now possible for extensions to easily override the proxy configuration without affecting user-visible preferences. (See nsIProtocolProxyService, nsIProtocolProxyFilter, and nsIProtocolProxyCallback.)
Dynamic Overlays
    Loading of XUL overlays after the document has been displayed is now supported. (See nsIDOMXULDocument.)
E4X
    The Mozilla JavaScript engine now supports ECMAScript for XML (E4X), a draft ECMA standard that adds native XML datatypes to the language and provides operators for common XML operations.
Translucent Windows (Windows/Linux)
    On Windows and Linux, XUL windows with a transparent background are now supported. This allows whatever is below the window to shine through the window background.
Adding tokens to the User-Agent string
    It is now possible for applications, extensions, and vendors to all add tokens to the User-Agent string (using default preferences) without overwriting each other. (details)
Toolkit chrome registry
    Chrome registration has been significantly improved to use simple plaintext chrome registration manifests, and no longer keeps the chrome.rdf/overlayinfo cache. See Chrome Registration.
Extension Manager

        * It is now possible to have Extensions outside the profile and application Extensions directories.
        * Installing extensions can now be done by dropping an XPI into the profile or application Extensions directory.
        * Uninstalling an Extension now involves simply deleting its folder from the profile or application Extensions directory.
        * Extensions can be installed on Windows by setting a value in the Windows registry. See this page for more details.

New Preferences Bindings
    These new bindings make it easier to create preferences windows for extensions. The new preferences windows support instant-apply behavior, which is enabled by default on Mac and Linux.
API for implementing new command-line switches
    An extensible API has been introduced so that extensions can easily handle complex command-line flags. This API will be stable and frozen for 1.1. See the interfaces nsICommandLine and nsICommandLineHandler.
XTF Support
    The eXtensible Tag Framework allows adding support for new namespaces using XPCOM components to Mozilla (written in JavaScript or C++). For example, the Mozilla XForms Project uses XTF to add support for the XForms namespace. See the XTF Home Page.
New Scriptable Windows Registry Interface
    A powerful and scriptable interface for accessing the Windows registry has been added to provide easy support for all applications. See the nsIWindowsRegKey interface. The component is accessible via the ContractID: @mozilla.org/windows-registry-key;1 (use createInstance, not getService).
    nsIWindowsShellService::getRegistryEntry has now been removed as it does not support handling of non-ASCII characters. Note that the open and readStringValue methods of nsIWindowsRegKey can be used in place of getRegistryEntry.

舞间道：支持，我两个版本都装上了。
