New spreadsheet functions

 * RAWSUBTRACT to subtract numbers without canceling out small roundoff errors. (Eike Rathke (Red Hat, Inc.))
 * =RAWSUBTRACT(a,b,c) is like =a-b-c, but the - minus operator cancels out small roundoff errors that are due to the fact that not every decimal number can be exactly represented as a binary floating point number and effectively the operation snaps to zero. RAWSUBTRACT uses the IEEE754 operation the platform/compiler provides. For example, =0.3-0.2-0.1 results in 0, whereas =RAWSUBTRACT(0.3,0.2,0.1) results in 2.77555756156289E-17
 * Note: Uncheck to get this result.
 * This can be used to compare whether a result exactly matches an expected number, i.e. if =RAWSUBTRACT(result,expected) equals 0.0
 * FORECAST.ETS a set of forecasting functions that use triple and double exponential smoothing and handle seasonal effects. (Winfried Donkers)
 * The Holt-Winters algorithms are used. Both Additional and Multiplicative methods are supported for triple exponential smoothing.
 * The set consists of the functions FORECAST.ETS.ADD*, FORECAST.ETS.MULT, FORECAST.ETS.SEASONALITY*, FORECAST.ETS.PI.ADD*, FORECAST.ETS.PI.MULT, FORECAST.ETS.STAT.ADD* and FORECAST.ETS.STAT.MULT. The functions marked with * are interchangeable with MS Excel2016.
 * CONCAT an enhanced version of CONCATENATE, allowing ranges, columns and references as arguments (Winfried Donkers)
 * The function is compatible with MS Excel 2016 function CONCAT.
 * TEXTJOIN to concatenate strings with delimeters between the strings. (Winfried Donkers)
 * TEXTJOIN allows the same string arguments as CONCAT and has a string argument that will be used as delimiter between the strings to be joined.
 * Also, it is possible to opt for empty cells to be skipped.
 * The function is compatible with MS Excel 2016 function TEXTJOIN.
 * IFS a cascaded IF-function (Winfried Donkers)
 * IFS works like if A then B else if C then D else if (etc.).
 * The function is compatible with MS Excel 2016 function IFS.
 * SWITCH a multiple choice selection function (Winfried Donkers)
 * SWITCH compares one expression with 1 to n possible values and returns the result belonging to the first values that equals expression.
 * The function is compatible with MS Excel 2016 function SWITCH.
 * MINIFS, MAXIFS (Winfried Donkers)
 * These statistical functions work like SUMIFS and AVERAGEIFS, but return the minimum respectively maximum value of the resulting range.
 * The functions are compatible with MS Excel 2016 functions MINIFS and MAXIFS.

Changed spreadsheet functions

 * WEEKDAY handles additional type argument values. (Eike Rathke (Red Hat, Inc.))
 * For interoperability with other spreadsheet implementations the following new argument values for the second Type parameter are accepted and let WEEKDAY return numbers from 1 to 7:
 * 11: Monday 1 to Sunday 7
 * 12: Tuesday 1 to Monday 7
 * 13: Wednesday 1 to Tuesday 7
 * 14: Thursday 1 to Wednesday 7
 * 15: Friday 1 to Thursday 7
 * 16: Saturday 1 to Friday 7
 * 17: Sunday 1 to Saturday 7
 * Previous versions accepted all integer values as Type argument, but any number not 1 or 2 or 3 was handled the same as 3, returning values starting with Monday=0. Now all values not of the set 1,2,3,11,12,13,14,15,16,17 let WEEKDAY return an error.

Support wildcards to be compatible with XLS/XLSX and with ODF 1.2
Simple wildcards as known from other spreadsheet applications can now be used in formula expressions. (Eike Rathke (Red Hat, Inc.))

Wildcards are
 * * (asterisk) any sequence of characters, including empty sequence
 * ? (question mark) any character, exactly one
 * ~ (tilde) escapes the special meaning of the following asterisk, question mark or tilde

See also and related section in ODF 1.2 table:use-wildcards and OpenFormula Host-Defined Behaviors

Wildcards are supported in all functions that already supported regular expressions, which are: all database functions DAVERAGE, DCOUNT, DCOUNTA, DGET, DMAX, DMIN, DPRODUCT, DSTDEV, DSTDEVP, DSUM, DVAR and DVARP; the functions COUNTIF, COUNTIFS, HLOOKUP, LOOKUP, MATCH, VLOOKUP, SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS and SEARCH.

Accordingly the setting was changed, under there is now a Enable wildcards in formulas radio button grouped with Enable regular expressions in formulas and No wildcards or regular expressions in formulas. When reading ODF spreadsheet documents with table:use-wildcards enabled or importing Microsoft Excel spreadsheet documents the option is set to wildcards enabled.

Using named expressions and ranges with sheet-local scope on other sheets
It is now possible to use a defined name with a scope local to a sheet in a formula on any other sheet. (Eike Rathke (Red Hat, Inc.))

For example, a named range LocalName defined with scope Sheet1 can be used in a formula on Sheet2 as, usual sheet name constraints for references apply, e.g. if the sheet name contains a blank it has to be enclosed in single quotes, as in

Copying named expressions and ranges while copying sheets
While copying entire sheets, named expressions and ranges that point to the copied sheet and are used by any formula cell that is copied along with the sheet are copied to new sheet-local scoped names. (Eike Rathke (Red Hat, Inc.))

For example, a document with sheet Sheet1 and the defined names and formula cells using the names global_global, global_local, local_global and local_local, copying Sheet1 to NewSheet will result in the defined names (Manage Names dialog invoked on NewSheet) thus the formulas continue to work and the names point to the copied cells as expected.

Classification according to TSCP-standards

 * In Writer, Calc and Impress there is the tool bar Classification that allows choosing the classification level.
 * Choosing the classification level will result in an info bar, and in Writer (depending on the level) also in a watermark and a field in the header and footer. All showing the level of classification. Of course the classification is stored in document properties.
 * In the current implementation there are three categories to choose from. The first one (named "Intelectual property" according to TSCP_BAILSv1) sets the header/footer and watermark (for certain levels). This is likely to be modfied in future versions.
 * Look for Classification Bar in the local or on line Help . Also see this blog entry. (Miklos Vajna, Collabora)

Incorporation of other languages
Our goal is to support as many languages as possible. We would like to thank the following people for voluntary translation in LibreOffice and help in preserving their native languages:



Improvements to proofing tools and language support

 * provides quite good results, however incorrect synonyms may be included
 * for non-commercial use, also a previous reliable thesaurus can be used (available in this Apache OpenOffice extension)

If you speak an endangered language and want to help us to achieve our goal of providing free tools for every single person on the Earth, please join us.

General

 * Support for embedding NPAPI Plugins (mostly Adobe Flash) in documents has now been removed.
 * 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.
 * Support was removed for the undocumented  flags    and.

Impress

 * It's now possible to manipulate context menus via the  API, by using URLs like  .  (Maxim Monastirsky)


 * Users of the  API, can now get the resource URL of the currently executing context menu, as the   attribute of the   struct implements the   interface. (It was implementing it earlier too, but was returning empty string.)  (Maxim Monastirsky)


 * The undocumented  service implementation (with implementation name  ) was removed.


 * The module  and the NPAPI Plugin related interfaces          were removed

The following UNO interfaces and services were changed:



Dispatch Commands
The  command and the underlying TaskPane code have been removed. The command used to show the TaskPane which was used in Impress before it has been superseded by the Sidebar. Legacy extensions using TaskPanes are still supported by the Sidebar. (Samuel Mehrbrodt, CIB)

SDK

 * The  command-line tool in the SDK has been superseded by   (running the latter without any arguments prints out usage information).  (It had already been used as a replacement for   inside the LO build environment, as it supports more input formats than merely the old-style binary   format, so this is a move to consolidate on a single tool again.)


 * generated C++ headers for UNO structs now contain  and
