包含有问号的数字格式码(例如<tt>0.???</tt>，这里的问号用于对齐小数位但是不显示零)将会被保存在ODF文档中了。{{tdf|40517}} (Laurent BP)
==== 表格的结构化引用 ====
{{tdf|85063}} (Eike Rathke, Red Hat)
* 表格的结构化引用功能早在5.0版本中已引入，但是5.0版本中有一些限制。在新的5.1版本中，以下限制已被解决：
** 列名不再必须作为单元格内容出现在表格的行标头中，现在可以对没有列标头的表格进行结构化引用了。
*** 在这种情况下，对于新的数据库区域，若区域中的列标头内容为空，则会生成诸如'''Column1''', '''Column2''', ... 的内部名称。
*** 在打开OOXML文档是，内部名称将被导入，并继续用于公式表达式中。
** 保存为OOXML时，结构化引用将会被写入（不再被转换为A1表达方式），并且table context将会被保留。
** 保存为OOXML时，定义的数据库区域将被导出为''<table>''元素.
* 当修改表头的单元格内容时，结构化引用中的内部列名称将会随之更新。
** 删除表头的单元格内容时，引用了该表头的公式将会继续有效，并可继续使用原来的表头名称进行编辑。
** 当复制表头单元格内容时，复制后的列名称将会被编号。例如，假设有两个名为'''FooBar'''的表头单元格，则列名称将会是'''FooBar'''和'''FooBar2'''。这将会自动在已有的公式表达式中体现。
** 当在表中插入列时，将会为表头单元格为空的列自动生成列名称，并以当前表的列序号作为标号。例如，在表的第三列之前插入两列，则生成的列名称将会是'''Column3'''和'''Column4'''。
*** 当在上述的空表头中输入内容时，已自动生成的列名称将会被更新。
** 每个表中的内部列名称是唯一的，会在显示已有的公式表达式中体现。
==== 锁定最后一列/最后一行的锚定 Sticky end column/row anchors ====
{{tdf|92779}} (Eike Rathke, Red Hat)
* 对于区域引用，若该引用跨越了至少两列或两列，且引用的终点位于工作表的最后一列或最后一行（例如'''AMJ'''或者'''1048576'''），则最后一列或最后一行将会被“锁定”，插入或者删除行或列时不会移动。
* 当插入或更新引用时，若最后一列或最后一列有可能到达工作表的行列范围之外从，则最后一行或最后一列的引用锚定将不再变化，从而避免产生<tt>#REF!</tt>错误。
** 例如，对于引用<code>B2:B1048575</code>，在插入两行时引用将变为<code>B2:B1048576</code>（此处的1048576是工作表的最后一行，在旧版本中插入两行后由于1048577不存在，从而产生<tt>#REF!</tt>错误)。
** 在上述例子中，行'''1048576'''被“锁定”了（Sticky）。
* 对于类似<code>B1048576:C1048576</code>的引用，最后一行的锚定不会被“锁定”，因为引用中只涉及一行。
==== 与 ODF 1.2 的兼容性 ====
函数WEEKNUM严格遵循 ODF 1.2规范，并引入了ISOWEEKNUM公式。 {{tdf|50950}} (Winfried Donkers + Eike Rathke)
* 在用户界面上，WEEKNUM_ADD 公式被重命名为了'''WEEKNUM_EXCEL2003'''，以便与 Microsoft Excel 创建的文档兼容。
** 打开用老版本Microsoft Excel 创建的此类文档时，WEEKNUM 公式将被映射到 WEEKNUM_EXCEL2003.
** 保存为ODF格式或者OOXML格式写入WEEKNUM时，老版本的 LibreOffice 和 OpenOffice.org 将其映射为 WEEKNUM_ADD.
** 对于新建的文档，将会使用WEEKNUM公式。
* '''WEEKNUM''' 现在支持 ODF OpenFormula (ODFF) 规范中定义的第二个参数的所有参数属性，见 http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#WEEKNUM
* 引入了'''ISOWEEKNUM'''公式，用于计算基于ISO 8601的日历周数，见 http://docs.oasis-open.org/office/v1.2/os/OpenDocument-v1.2-os-part2.html#ISOWEEKNUM
* '''WEEKNUM_OOO''' provides compatibility with older LibreOffice and OpenOffice.org releases for cases that can not be mapped to WEEKNUM or ISOWEEKNUM as defined in the standard, specifically if the ''mode'' argument is '''1''' the old WEEKNUM implementation returned a week number calculated as if it was an ISO 8601 calculation but with the week starting on Sunday instead of Monday. This is not covered by any standard.
** Not offered in the Function Wizard to prevent accidental use. Use it only if interoperability with older LibreOffice or OpenOffice.org releases is required.
** Currently still saved wrongly as ISOWEEKNUM with 2 parameters for interoperability with older LibreOffice or OpenOffice.org releases.
*** This will be changed in future for release 5.3 and the function will be saved as ''ORG.LIBREOFFICE.WEEKNUM_OOO'', the current 5.1 release is already enabled to read that.
== Impress演示文稿和Draw绘图 ==
* Slide navigation and sorting commands were added with corresponding shortcut keys. {{tdf|91909}} (Philippe Jung, Yousuf Philips)
* Master slide view appears in a different background color to normal view. {{tdf|87905}} (Katarina Behrens, CIB)
* KDE, XFCE, and Mate ScreenSavers are now also inhibited when presenting (Andrzej Hunt).
=== Impress模式选择 ===
Several modes were active in Impress:
* Page to edit slides content
* Page Master to edit slides container
* Notes to add Notes
* Notes Master to edit Notes container
* Plan to sketch a presentation
* Handout to define the handout format
* Slide sorter to organise presentation
It was hard to navigate between Master / non master modes. Tabs above the working area were jumping right and left, consuming screen space.
Now, two toolbox icons have been added:
* one to toggle Tab bar visibility. It is hidden by default. Clicking the toggle disables the new Mode Selection tool and restores the previous behaviour.
* one to Select the Working mode among the 7 modes listed above. It is divided in two zones: top zone is regular mode (dealing with content of the presentation), bottom zone is the Master mode (dealing with container).
[[File:impress_mode_selection.png|450px|center|thumbnail|New mode selection]]
=== 幻灯片设计 ===
Slide Design dialog in {{bc|Slide|Slide Design}} now affects all selected (standard) slides. (Caolán McNamara, Red Hat)
=== 使宽度/高度相等 ===
When multiple objects are selected, the right click context menu ''Shapes'' submenu now supports Equalize Width and Equalize Height which adjusts the width/height of the selected objects to the width/height of the last selected object. (Caolán McNamara, Red Hat)
[[File:Equalize.png|thumb|center|450px]]
=== 保存背景图像 ===
Right clicking a slide now supports saving a background image to file, this matches the pre-existing set background image option. (Caolán McNamara, Red Hat)
[[File:Save-bg.png|thumb|center|450px]]
=== 查看/编辑控制点 ===
The Shape Properties dialog for enhanced shapes now lists and enables editing the control points. This is in addition to the preexisting mechanism of selecting with the mouse the yellow control handle of the shape, but enables viewing and fine control over the control values. (Caolán McNamara, Red Hat)
[[File:Control-points.png|thumb|center|450px]]
=== 演讲者控制台 ===
There is now a button on the presenter console to restart the timer of the slideshow without restarting the slideshow itself (see this [http://vmiklos.hu/blog/presenter-console.html blog entry]) (Miklos Vajna, Collabora; Andreas Kainz)
[[File:Presenter-restart.png|thumb|center|600px]]
=== OpenGL 幻灯片过渡 ===
All OpenGL transitions have been ported to OpenGL 2.1+, which removes support for very old GPUs but allows a better usage of modern ones. Four new transitions have been added and exploit these new available features. (Emmanuel Gil Peyrot, Collabora; Tomaž Vajngerl, Collabora)

== Math 数学公式 ==
=== 自动闭合括号是可选的===
* 自动闭合括号现在属于可选的。 {{tdf|43090}}
=== 从剪贴板导入 MathML ===
(Regina Henschel)
* The tool “Math Input Panel” in Windows or the context menu of a formula in a browser allow to copy the MathML source to clipboard. The Math module in LibreOffice has got a new item “Import MathML from Clipboard” in menu Tools to import such source and convert it into LibreOffice’s own formula syntax StarMath.

|}
</center>
* MathML and StarMath have some differences and therefore sometimes corrections on the imported formula are needed, but most of the formula should be correct. If a conversion is not possible, nothing happens.
[[File:Release51ScreenshotMathMLImport.png|thumb|center|Import MathML screenshot]]
* The import expects, that a <nowiki><math></nowiki> element exists, which has an attribute <nowiki>xmlns="http://www.w3.org/1998/Math/MathML"</nowiki>.
[[File:Release51ScreenshotMathMLImportResult.png|263px|center|thumb|Result of importing MathML]]
== Base 数据库 ==
Ancient SeaMonkey based mozab driver was only used on Windows 32 bit
and is removed now. This functionality is replaced with mork driver,
that supports Thunderbird address book.
Given that SeaMonkey based mozab driver also provided Outlook and Outlook
Express address book integration, that Windows 32 bit only feature is lost
for now. Note that Windows 64 bit never supported ancient SeaMonkey based
mozab driver.
== Chart 图表 ==
=== 趋势线 ===
* Exponential and Power trend lines accept negative Y values {{tdf|70673}} (Laurent BP)
* Improve equation rendering by removing some useless 1: (Laurent BP)
** polynomial: <code>f(x) = 1x^2 + 1x +1</code> => <code>f(x) = x^2 + x +1</code>
** exponential: <code>f(x) = exp( 1 x )</code> => <code>f(x) = exp( x )</code>
== Core 核心 ==
=== 使用{{key|Alt|X}}输入Unicode字符 ===
Some Windows applications, such as Microsoft Word and WordPad, permit the user to input arbitrary Unicode characters by typing an hexadecimal code point (for example, <code>2026</code> for <code>…</code>) and then pressing {{key|Alt|X}}. LibreOffice now includes this functionality as well. (Note: This feature adds to the long-existing, equivalent Linux/GTK functionality of pressing {{key|Ctrl|Shift|U}}+hexadecimal code point.) {{tdf|73691}} (SIL)
'''Details:'''
* Toggles (switches back and forth) between the character before the cursor and its Unicode notation.
* Intelligently handles combining characters, expanding the entire character immediately.
* Selection is not necessary, but if used will limit the input to those characters. (Draw/Impress/Calc have the final result selected, but not Writer.)
* Handles all 16 Unicode planes
* Available in Writer, Draw, Impress, Calc and Math.
* Re-assignable keyboard shortcut: {{bc|Tools|Customize|Keyboard|Category:Options|Function:Toggle Unicode Notation}}. Defaults to {{key|Alt|X}} assigned at the global level. ({{key|Alt|C}} used for Basque/Dutch/Galician/German/Brazilian-Portugese locales and {{key|Command|Option|X}} used for MacOS).
=== WebDav 功能改进 ===
* Better LOCK/UNLOCK support {{tdf|82744}} (Giuseppe Castagno)
* Support a (<code>https</code>-like) non-standard <code>vnd.sun.star.webdavs</code> URL scheme in addition to the non-standard (<code>http</code>-like) <code>vnd.sun.star.webdav</code> scheme, {{commit|d3de490437df4c9093f32e97fc185066d64c0f46}} (Stephan Bergmann, Red Hat)
== Options / General ==
* Support for the HKEY_CURRENT_USER Windows registry hierarchy which enables per-user configuration policies (Michael Meeks, Collabora)
== 筛选器 ==
=== 新的导入筛选器 ===
* Gnumeric is now an officially supported import format (does not work on Windows) (It was supported as part of the experimental features for some time) (Markus Mohrhard)
* Microsoft Write (.wri files) can now be imported, via libwps. (Sean Young)
* Apple Keynote 6 files can now be imported, via libetonyek. {{tdf|88682}} (David Tardon, Red Hat)

=== OpenXML筛选器的改进 ===
* Export of the modified VBA stream back to binary Microsoft formats and OOXML (Rosemary Sebastian, Markus Mohrhard)
** There is a new configuration value that allows to control whether to use this feature (by default yes) or switch back to the old behavior of discarding or writing back the unchanged stream
** The following features are not yet (completely) supported: Protected macros, macro sheets, active x and some of the designer features.
* Improved export of embedded objects to DOCX and PPTX, including export of Math formulas (Michael Stahl, Red Hat)
* Numerous other improvements to the Microsoft OOXML import and export filters, the Microsoft Office binary file formats and the RTF format. Details:
** OOXML Filters → [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=oox OOXML], [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=docx DOCX], [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=xlsx XLSX], [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=pptx PPTX], [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=vml VML], [http://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=drawingML drawingML]

* Do not drop empty text lines. {{tdf|67873}} (David Tardon)
== GUI 用户界面 ==
* In dialog {{bc|Tools|Options|LibreOffice|View}} was added displays the current status OpenGL: Enabled or Disabled
[[File:Current status OpenGL.png|300px|thumb|center]]
=== 重新组织了菜单 ===
The main menus in Writer, Calc and Impress were reorganized to improve usability, group similar functions together, add functions that were not present and sorting items based on their usage and importance. [https://design.blog.documentfoundation.org/2016/01/22/way-down-in-the-libreoffice-menus/ blog entry]
*Reorganization of the menus in Writer, including the addition of a Styles menu {{tdf|91781}} (Yousuf Philips)

[[File:Slide Transition 5.1 -EN.png|350px|center|thumbnail|Section Slide Transition in Impress 5.1]]
* New Chart sidebar {{tdf|91063}} (Markus Mohrhard, Yousuf Philips, Heiko Tietze)
** Some limitations still apply
[[File:LO Chart Sidebar Elements 5.1.png|center|thumb|300px|New section Elements for Charts in Sidebar for version 5.1]]
* Image flip buttons are now available in Writer also (Samuel Mehrbrodt [CIB])
[[File:Flip-sidebar-writer.png|thumb|center|450px|Images can now be flipped in the Sidebar in Writer]]

[[File:Autocorrect context menu.png|center|thumbnail]]
=== 拼写检查对话框改进 ===
* The Spelling Dialog now has a toolbar for pasting and inserting special characters. {{tdf|95682}} (Caolán McNamara, Red Hat, Inc.)
[[File:Insert-symbol-spell-dialog.png|thumb|center|450px]]
=== Linux/Gtk ===
* Enable auto-accelerator behaviour for gtk {{tdf|92630}} (Simon Long, Raspberry Pi)
== 本地化 ==
=== 新的语言和本地化数据 ===
Available as default document language and for locale specific formatting.
* Added locale data for Arabic [ar-BH] [ar-IQ] [ar-JO] [ar-LY] [ar-MA] [ar-QA] [ar-SY] [ar-YE]. {{tdf|95485}} (Ghasan Al-Sakkaf and Eike Rathke)
=== Improvements to proofing tools and language support ===
* Proofing tools for German language (de-AT, de-CH, de-DE) have been largely improved ({{tdf|96782}}):
** The spell-check dictionary now contains over 250,000 words. The new version adds over 20,000 new words.
** The thesaurus now contains over 135,000 words in over 35,000 meaning groups. The new version adds ~ 35,000 new words.
** The hyphenation patterns have been updated and contain an improved exception list.
* Updated Slovenian thesaurus (Martin Srebotnjak)
* New Guarani (gug-PY) thesaurus (Giovanni Caligaris and Olivier Hallot)
* Updated Hungarian spell-check dictionary ({{tdf|95024}}), major update, implemented the spelling reform defined by the 12th edition of Rules of Hungarian Spelling (by the Hungarian Academy of Science, 2015) (László Németh, Collabora)
* Updated Greek spell-check dictionary ({{tdf|94415}})
* Updated Portuguese (pt-PT) spell-check dictionary
* Updated Swedish spell-check dictionary
* Updated Spanish spellcheck dictionary (Ricardo Palomares)
== 性能提升 ==
=== Calc ===
* SUM function now uses optimized arithemetic and SSE3 if present, giving a ~5x win for large sums (Michael Meeks, Collabora, Tomaz Vajngerl, Collabora)
* Formula Group SoftwareInterpreter used for simple functions: +, -, *, /, Sum, Product giving a 2x+ win for large function runs (Jan Holesovsky, Collabora)
== Python 和 Basic 脚本 ==
=== PyUNO 现在更加像Python了 ===
(Matthew J. Francis)
*Simplifies working with UNO objects by giving the behaviour of Python lists, dicts and iterators to objects which implement UNO container interfaces
*Applies a custom behaviour to allow objects which implement com::sun::star::table::XCellRange to yield cells and cell ranges by subscript
*When UNO container objects are addressed in the new style, eliminates the requirement to manually construct Any objects for contained elements which are typed sequences
*Allows lists and iterators to be passed wherever a UNO method accepts a sequence
*Relaxes the requirements for initialising UNO structs to allow some members to be skipped when all initialisers are passed by name

[http://conference.libreoffice.org/assets/Conference/Aarhus/Slides/MatthewFrancisPyUNO.pdf PDF: Presentation at Aarhus]
=== 更新了 Access2Base ===
Access2Base, the Basic library for Base users, is now available in its version 1.4.0 (Jean-Pierre Ledure).
The main improvements are related to the OutputTo action, which makes it easy now to export the data contained in a Base table or query to Calc, Text or HTML pages.
Examples of HTML output are available on the [http://www.access2base.com/access2base.html#OutputToStyling documentation site].
=== 更方便地访问 LibreOffice API 的在线文档 ===
There is a <code>theServiceDocumenter</code> singleton available now. It provides the <code>showServiceDocs()</code> method, that opens the documentation of any UNO service passed to it. This allows faster orientation in rapid application development -- esp. in Basic or Python scripting or extension development. [https://www.youtube.com/watch?v=WBNG6bVZPzw There is a short video of a talk at the LibreOffice conference] available, which both discusses basic concepts of the UNO API and how the new documenter helps developers.
== Feature removal / deprecation ==
*Embedding [https://en.wikipedia.org/wiki/NPAPI NPAPI] Plugins (mostly Adobe Flash) in documents now warns you this is deprecated. It will not work in all environments and support for NPAPI is being removed in the 5.2 release.
*[https://en.wikipedia.org/wiki/ActiveX ActiveX] support is considered deprecated and may be removed in the future. If this change negatively affects your Windows application please email the LibreOffice development list with your use case and plan for moving off of ActiveX. We specifically want feedback if you use ActiveX to embed LibreOffice components into your application.
== API changes ==
=== Removed configuration options ===
