    LibreOffice 4.2 的变化

    关于本页面

    注：本页面尚未翻译完成，文本只是从英文页面复制。欢迎参与翻译。

    This is an in-progress scratch-pad of notes to build release notes from as and when we release. Please do not list features that are to be shipped already in the 4.1 release! Please do not add wish-list features that you hope will be implemented, but only what actually is implemented already.

    What does a good feature look like here:

    • It has a short description, and a way for a busy reviewer to find and play with the feature. Target someone who is extremely busy, and knows little-to-nothing about the product. So if a user interface element is key to the feature, be very explicit about where it is, e.g. using a menu path that leads to it: Format ▸ Character ▸ Position [tab] ▸ ‘90 degrees’.
    • It credits the main authors who did the work (add them in parentheses after the feature description) and references the relevant Bugzilla ticket.
    • If the feature can be shown off with a sample file – particularly for new import-able features, it would be wonderful to have a link to a test file that we can use to show that feature off to best effect. That really helps us to make good screenshots to show off the features, and allows reviewers to do their testing.

    For more details, see the guidelines.

    Thanks in advance for your help filling this out!


    安装包 (只适用于windows)

    • The option to select which Modules to install has been removed from the Windows Custom install dialog (Andras Timar). The option made little sense (all the modules are included in the program: it was just the Start Menu icons/shortcuts that were suppressed) and was a source of bugs

    Base数据库

    • INCOMPATIBLE CHANGE: a checkbox bound to a (var)char (string) field will now write 'true' or 'false', whereas up to LibreOffice 4.1 it wrote the strings '1' or '0'. The read behaviour is backwards compatible and will recognise values '1' or '0'. (Lionel Elie Mamane)
    • NEW FEATURE: reference values in checkboxes are now honoured. This allows to have again the old behaviour of writing '1' or '0' if desired. It also allows e.g. to invert the behaviour of the checkbox (bound to a boolean field) by setting the checkbox properties as follows 'Reference (on): false' and 'Reference (off): true' (Lionel Elie Mamane)

    Core核心

    选项 / 一般

    Windows注册表变化

    Windows Registry as a configuration backend. Under Windows, LibreOffice uses keys under HKLM/Policies/LibreOffice as a configuration layer on the top of program's layer and below user's layer.

    The following structure is assumed: Last element of Key becomes prop, first part is the path and optionally nodes, when the node has oor:op attribute. Values can be the following: Value (string) and Final (dword, optional) For example the following registry setting: 

    [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\LibreOffice\org.openoffice.UserProfile\Data\o]
"Value"="Example Corp."
"Final"=dword:00000001

    becomes the following in configuration: 

    <item oor:path="/org.openoffice.UserProfile/Data">
    <prop oor:name="o" oor:finalized="true">
        <value>Example Corp.</value>
    </prop>
</item>

    Another example: 

    [HKEY_LOCAL_MACHINE\Policies\LibreOffice\org.openoffice.Office.OptionsDialog\OptionsDialogGroups\ProductName/#fuse\Pages\BasicIDEOptions/#fuse\Hide]
"Value"="true"

    becomes the following in configuration: 

    <item oor:path="/org.openoffice.Office.OptionsDialog/OptionsDialogGroups">
    <node oor:name="ProductName" oor:op="fuse">
        <node oor:name="Pages">
            <node oor:name="BasicIDEOptions" oor:op="fuse">
                <prop oor:name="Hide">
                    <value>true</value>
                </prop>
            </node>
        </node>
    </node>
</item>

    With this feature it becomes possible to centrally manage LibreOffice configuration with Group Policy Objects in a Windows domain. It is possible set and optionally lock many LibreOffice settings. The feature was developed by the order of Hungarian E-Governmental Free Software Competence Centre.

    • Brazilian Portuguese (pt_BR) spell-check dictionary updated.(Raimundo Moura, Marcos Paulo de Souza and Alexandre Vicenzi)
    • Spanish spell-check dictionary updated.
    • Swedish spell-check dictionary updated.

    Data stream dialog
    • NEW TECHNOLOGY PREVIEW FEATURE: Firebird SQL connector for LibreOffice Base (Andrzej Hunt). When creating a new Database, select Firebird Embedded in the drop down menu (you have to first enable the Experimental features in Tools ▸ Options ▸ LibreOffice ▸ Advanced). This allows creation of databases that perform many times faster than the previous built-in HSQLDB 1.8, avoiding the C++-to-Java overhead inherent in using HSQLDB. We plan to phase HSQLDB out over the next few releases, and provide a smooth migration path to Firebird. Connecting to modern HSQLDB 2.x external databases remains available through HSQLDB's native interface, namely JDBC.

    Start of a few words about Firebird, please feel free to improve following description of Firebird: "The integration of Firebird in LibreOffice Base is a big step forward. Firebird is a mature relational SQL database that is ACID-compliant and boasts cross-platform support, multi-generation architecture, referential integrity, logging and monitoring capabilities. It offers high performance, excellent concurrency and powerful language support for stored procedures and triggers, and more. It has been used in production systems, under a variety of names, since 1981."

    Firebird Embedded
    • On Windows there is a new experimental accessibility bridge supporting IAccessible2 (IA2), based on code from IBM. By default the legacy Java Access Bridge (JAB) will be used, and Experimental features in Tools ▸ Options ▸ LibreOffice ▸ Advanced switches to the new IA2 bridge; in LO 4.3 the JAB will be removed in favour of IA2. Please check that your accessibility tool supports IA2 before trying it out; NVDA is known to work. For more details see Development/ia2.

    性能

    Calc 电子表格

    • Calc's cell storage structure has been completely re-written, to store contiguous cell values in contiguous memory region to improve locality of reference as well as the cost of storage. The new structure also enables hardware accelerated parallel calculations of a large number of cells. (Kohei Yoshida)
    • Calc core now shares all string instances stored in cells and several other places in order to significantly speed up both case sensitive and case insensitive string comparisons, and also to allow string equality check in OpenCL-based formula interpreter. This change also speeds up execution of several cell functions (such as VLOOKUP) that perform a large number of string equality comparisons. Filtering of rows via AutoFilter, Standard Filter, and Advanced Filter should run faster thanks to shared strings. (Kohei Yoshida)
    • Vertically adjacent formula cells containing identical formula token set now share their formula token array instance. This can drastically reduce run-time memory usage of Calc, and also speeds up automatic reference updates when moving cells. (Kohei Yoshida)
    • XLSX import filter has been re-worked to achieve significant boost on the import performance on XLSX documents. The speed up was achieved by moving much of the temporary string allocations and deallocations that occur during the XML parsing phase to a separate thread, and also by re-working the handler logic on the Calc side to reduce inefficiencies, especially with regard to importing of formula cells. (Kohei Yoshida, Michael Meeks, Matúš Kukan)
    • Added an experimental multi-threaded import for XLSX documents. When the experimental features are enabled, Calc tries to import XLSX documents using multiple threads, to import multiple sheets concurrently. (Kohei Yoshida, Michael Meeks)
    • Significant speed up on the export of ODS document that contains a large number of rich-text cells. Refer to this blog post for more details. (Kohei Yoshida)
    • Cell note storage has been re-worked to use multi_type_vector, in order to improve the performance of import and export of documents containing large number of cell comments. (Laurent Godard)
    • Improved performance of VLOOKUP function with use of external references. (Pierre-Eric Pelloux-Prayer)
    • Improved performance of SUM, COUNT, and SUMIFS function. (Kohei Yoshida)

    基础设施

    • Added 64-bit builds for macOS.
    • New experimental liblibreoffice API that allows (initially) LibreOffice's filters to be re-used by directly linking to the LibreOffice core. This has a simple C and wrapper C++ API, and brings no run-time dependency (via a very tiny static library / shim) (Michael Meeks)
    • Symbols & source server for LibreOffice on Windows.
    • When a bug is experienced on Windows, it is now easy to get a backtrace or more information about that via Symbols Server and Source Server. (Fridrich Štrba, Luboš Luňák, Jan Holešovský, Christian Lohmaier)
    • More info on how to use it.

    Scripting / Base

    • LibreOffice now bundles Access2Base, a simplified API for scripting of Base (and Writer database forms) in the Basic programming language. It is more concise and easier to learn than the cross-language standard UNO API.

    API变化

    移除已弃用的配置选项

    C++ UNO language binding and URE libraries

    Java

    New style services

    A large number of existing UNO services were converted to new-style services, which allow for more convenient and more type safe construction; this has no impact on compatibility of existing client code. (Noel Grandin)

    Autodoc被doxygen代替

    The SDK no longer contains the autodoc documentation tool 9d93ed7cd1b36830f6d7aedd4e6f15667774de1d.

    IDL API documentation can be extracted by doxygen version 1.8.4 or later instead. Download it from http://www.stack.nl/~dimitri/doxygen/download.html

    There are some differences in the documentation markup between autodoc and doxygen; the warnings printed by doxygen are helpful in finding comments that need tweaking.

    uno-skeletonmaker

    The obsolete --java4 command line parameter was removed from the uno-skeletonmaker tool 3cb10e9220da27ca7db2f68007be9e310bdefc4d
