ODF 1.0 feature hyphenation-keep, i.e. disabling hyphenation across page etc. was implemented by shifting the full hyphenated line (fixing also the DOCX layout interoperability, when value of the useWord2013TrackBottomHyphenation MSO DOCX compatibility option is true). To shift only the last word, add UNO paragraph property com::sun::star::text::ParagraphHyphenationKeepLine and the associated layout in Writer core, i.e. disabling the hyphenation in the last line, instead of line shifting, if the value of ParagraphHyphenationKeepLine is true. Fix missing DOCX layout interoperability by mapping the unhandled useWord2013TrackBottomHyphenation = false case to the new layout. Note: shifting lines may be better for languages with long words, but only with 1) typesetting with line-level (greedy) line breaking instead of the desirable paragraph-level, 2) and with missing optimized hyphenation at boundaries of compound word constituents, and 3) forgotting the following: Shifting only words or word constituents are better for 1) equal line count on pages and spreads (very basic typographical requirement), 2) disabling hyphenation really (shifting doesn't guarantee this, because shifting is limited in a single line, but the previous line can be hyphenated, too) and 3) more compact typesetting. Both hyphenation-keep algorithms are important for interoperability, but the new HyphenationKeepLine can create state-of-the-art automatic typesetting with the planned improvements.

LibreOffice API IDL Files Except UDK API
Contains all of the IDL files except those in udkapi.
i.e. the interfaces that are specific to the LibreOffice application. An artificial (?) separation.
The reference offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl (formerly combined into a single
offapi/type_reference/types.rdb) are used to detect inadvertent incompatible
changes. They are plain-text .idl files (not strictly lexicographically sorted,
though, so they satisfy the .idl file requirements for no forward dependencies),
so in cases where we deliberately /do/ become incompatible they can be modified
manually.
Old such cases of deliberately becoming incompatible are listed in
offapi/type_reference/typelibrary_history.txt, newer such cases are recorded in
the git logs of (now superseded) offapi/type_reference/types.rdb,
offapi/type_reference/offapi.rdb, and udkapi/type_reference/udkapi.rdb, new such
cases are recorded in the git logs of offapi/type_reference/offapi.idl and
udkapi/type_reference/udkapi.idl.
