Điều khiển biểu mẫu dựa trên văn bản có thể tương tác
LibreOffice đã nhập các biểu mẫu Microsoft Word một cách hợp lý - nhiều thứ đã được cải thiện qua nhiều năm - và từ LibreOffice 6.3 trên đó cũng có thể thêm các điều khiển biểu mẫu Word. Sau khi thiết lập các tùy chọn, menu Forms trong Writer thay đổi. Có nhiều điều thú vị hơn để biết về sự cải thiện này với các hình thức; xem thêm trang này: Form controls in LibreOffice
 * Bố cục menu biểu mẫu tùy chọn, tương tự như Microsoft Office (Tamás Zolnai, Collabora)
 * Implement GUI cho các điều khiển biểu mẫu cũ (Tamás Zolnai, Collabora)

Calc

 * Added UNO API to let cell anchored graphics resize with the cell (Samuel Mehrbrodt, CIB)
 * Added new Russian ruble currency symbol to currency formats. It will display the ₽ character (U+20BD) instead of руб. or other localized variants (Eike Rathke, Red Hat)
 * Added new drop-down widget into formula bar instead old tool Sum (Gagandeep Singh)
 * User can disable the extra dialog for search results. For activate of this dialog use option Show summary of replaced cells in dialog  (Heiko Tietze)
 * Added a new checkbox in dialog that allows trimming of the input range to the actual data content before computing moving-average. This checkbox is enabled by default. Also fixed the underlying performance problem even for the case when this checkbox is disabled (Dennis Francis, Collabora).
 * The auto-filter popup no longer flickers on Windows without OpenGL (Miklos Vajna, Collabora)
 * It's now possible to sort range containing a protected labels row (Martin van Zijl)

Rework dialog
All work was made by Eike Rathke commit


 * Add “With replacement” checkbutton
 * checked: WR (with replacement, put back after draw), larger sample size than population size possible
 * mutually exclusive with “Keep order”
 * unchecked: WOR (without replacement, do not put back after draw), sample size limited to population size
 * automatically unchecked for “Periodic” samples


 * Add “Keep order” checkbutton
 * checked: samples are drawn in order of population data
 * WOR method mutually exclusive with “With replacement”
 * automatically checked for “Periodic” samples
 * unchecked: samples are drawn in random order




 * Các trường đầu vào giới hạn “Sample size” và “Period” theo quy mô dân số cho tất cả các phương pháp WOR
 * khi giới hạn, tăng “Sample size” và “Period” lên đến giá trị được biết đến cuối cùng của chúng khi mở rộng quy mô dân số

Previously, for “Periodic” samples the “Period” field was never limited, which for populations of smaller size makes no sense.

The new recent implementation for “Random” without “Keep order” and without “With replacement” set (WOR) strictly needs “Sample size” limited to population size.

FOURIER function
FOURIER(Array, GroupedByColumns, Inverse, Polar, MinimumMagnitude) is a matrix formula that computes discrete Fourier transform [DFT] of an input array (first argument) using a couple of Fast Fourier Transform algorithms. All features of this formula will also be available graphically via the dialog  blog (Dennis Francis, Collabora)

The data in input array(first argument) can be:
 * grouped by columns (needs to be indicated by flag GroupedByColumns = TRUE). In this case the array can contain 1 or 2 columns, where the first column contains the real part of input sequence and second column if present contains the imaginary part of the input sequence. If there is only 1 column, the input sequence is treated as purely real.
 * grouped by rows (needs to be indicated by flag GroupedByColumns = FALSE). In this case the array can contain 1 or 2 rows, where the first row contains the real part of input sequence and second row if present contains the imaginary part of the input sequence. If there is only 1 row, the input sequence is treated as purely real.

The third argument “Inverse” is a boolean flag to indicate whether an inverse DFT needs to be computed. This argument is optional and the default value is FALSE.

The fourth argument Polar is a boolean flag to indicate whether the final output needs to be in polar coordinates. This argument is optional and the default value is FALSE.

The result of DFT consists of two columns - first column contains the real parts (or the magnitudes if Polar=TRUE) and second column contains the imaginary parts (or the phases if Polar=TRUE).

There is a 5th optional parameter, MinimumMagnitude. This parameter is used only if Polar=TRUE. All frequency components with magnitude less than MinimumMagnitude will be suppressed with a zero magnitude-phase entry. This is very useful when looking at the magnitude-phase spectrum of a signal because there is always some very tiny amount of rounding error when doing FFT algorithms and results in incorrect non-zero phase for non-existent frequencies. By providing a suitable value to this parameter, these non-existent frequency components can be suppressed. By default the value of this 5th parameter is 0.0, so *no* suppression is done by default.



Performance

Impress & Draw

 * Users may now drag’n’drop multiple Impress animations to reorder them. (Brian Fraser) commit
 * Introduce an expert option ‘WriteLayerStateAsConfigItem’ with default value ‘true’. If you set it to ‘false’, the visible/printable/locked state of layers are only written ODF conform to part styles.xml, otherwise to settings.xml in addition. You might need the option ‘false’ to avoid inconsistency in case you manipulate layers via macro. (Regina Henschel) commit
 * OOXML preset shapes as used by PowerPoint or SoftMaker had some glitches in handle-movement, when you tried to alter the shapes in LibreOffice. The shape outline moved in opposite direction of the handle movement, or the handle jumped to a new location, when you touched it, or the handle was not movable at all. That is fixed for most shapes now. (Regina Henschel,, , , )

 * If an unmodified template document is opened in an existing window, it will no longer be overwritten by a new document. Instead, a new document will open in a new window (Katarina Behrens, CIB)
 * The Apple Advanced Typography (AAT) layout is now supported on all platforms. (Khaled Hosny)
 * Ability to read and optionally generate MSO lockfiles was added. Now LibreOffice can report who of MS Office users has locked a document by reading the lock files generated by MS Office; and when "Create MSO lock file" is checked at, LibreOffice would generate such files in addition to own lock files, to allow MS Office users to know who has locked documents, too. , (Mike Kaganski, Collabora / Tamás Zolnai, Collabora)

New Feature: Redaction
Now it is possible to redact your documents with LibreOffice to remove/hide sensitive information. blog post (Muhammet Kara, Collabora)



What?
Redaction in its sanitization sense is the blacking out or deletion of text in a document, or the result of such an effort. It is intended to allow the selective disclosure of information in a document while keeping other parts of the document secret. Typically the result is a document that is suitable for publication or for dissemination to others than the intended audience of the original document. For example, when a document is subpoenaed in a court case, information not specifically relevant to the case at hand is often redacted. Redaction in Wikipedia

Although there are some proprietary software applications in the market for this purpose, they have their own limitations like lack of support for open/libre document formats. Thanks to LibreOffice's great support for various file formats, and our recent work on implementing this new feature on top of it, it is now possible to redact most of your documents without leaving the comfort of your favourite office suite.

How?

 * Open your document in LibreOffice
 * Click from the main menu, and wait for your document to be prepared for redaction (converted to an internal meta-format, and transferred to Draw)
 * Do the redaction by using the “Rectangle Redaction,” and the “Freeform Redaction” tools on the “Redaction Toolbar”
 * Save & share the in-redaction copies of the document with peers either in the modifiable (odg) or the verbatim (pdf) format at your option
 * Once you are ready to finalize the redaction, click the desired option on the “Redacted Export” tool on the Redaction toolbar

Some Notes:
 * As a result, you will have a pixellized version of the redacted document in PDF. There will be no selectable text in it, and the redacted content will be non-existent.
 * During redaction, the redaction shapes will be transparent and in grey so that the user can see what they are redacting.
 * There are currently 4 tools on the Redaction toolbar (from left to right): Rectangle Redaction, Freeform Redaction, Redacted Export, Direct Export to PDF
 * The Rectangle Redaction tool allows the user to mark the content for redaction by drawing transparent rectangles covering the content
 * The Freeform Redaction tool allows the user to mark the content for redaction by drawing freeform lines/polygons covering the content
 * The “Redacted Export” button box has two options: “Redacted Export (Black)” and “Redacted Export (White).” When clicked, it will finalize your document (by converting the transparent grey redaction shapes to opaque black or white shapes), and export as a pixellized PDF file. The “White” option might be preferred to save toner while printing.
 * The Direct Export to PDF button allows the user to take an in-redaction copy of the document in PDF to share as a verbatim copy for review

KDE4 is out of maintenance upstream since November 2014. LibreOffice’s KDE4 VCL plugin has been removed and binaries provided by TDF have switched to KDE5 as the official backend.

GTK+2 VCL plugin
The GTK+2 VCL backend is deprecated and will be removed in the next version.

Personalization
Firefox Personas search & apply functionality has been removed from the personalization dialog as per the ESC & Design Team decisions, after major changes on the Mozilla side, which made it impossible to use their legacy API and the themes data for us. The default personas are unaffected, and still functional. Future improvements and more features are planned by the Design Team, thanks to now having a clean slate, without the burden of chasing an external API. Firefox Personas themes are dead; long live the LibreOffice Themes! :) (Muhammet Kara, Collabora)

Please beware that although users may continue using their already installed personas as long as they don’t switch to a default persona; once a default persona is applied, there is no way to go back to the custom theme via normal means.

32-bit builds removals
Binary Linux x86 (32-bit) releases will be demoted. There will be no Linux x86 builds produced by TDF after 6.2. This does not mean that Linux x86 compatibility will be removed. If you need a 32 bit build, please have a look at your distribution.

UNO API changes

 * The range of supported values for a Writer document’s  property   has been reduced from 5–1000 to 20–600.


 * Registering a XMouseListener/XKeyListener to a XWindow will now submit mouse/key events even if technically the events happened in a widget inside that window. - this has been reverted in LibreOffice 6.3.4 due to various regressions (see ) (Samuel Mehrbrodt, CIB)

UNO API additions

 * A method  has been added to the XModel2 interface. It allows to set some MediaDescriptor properties during runtime. (Samuel Mehrbrodt, CIB)
