Problem: possible crash with winminheight=0
(Emilien Breton)
Solution: Use <= instead of < when checking reserved room in
frame_setheight() to correctly handle the zero-height
boundary case (Hirohito Higashi).
In frame_setheight(), when shrinking the current window and the only
other window has 'winfixheight' with 'winminheight'=0, room_reserved
was not cleared because the condition used '<' instead of '<='.
The freed rows were discarded, leaving fr_height sum less than
topframe fr_height. Subsequent resize operations then computed a
wrong room_cmdline that expanded topframe beyond the screen, causing
a crash.

Problem: When using 'diffopt=inline:word', lines were excessively
fragmented with punctuation creating separate highlight
blocks, making it harder to read the diffs.
Solution: Added 'diff_refine_inline_word_highlight()' to merge
adjacent diff blocks that are separated by small gaps of
non-word characters (up to 5 bytes by default) (HarshK97).
When using inline:word diff mode, adjacent changed words separated by
punctuation or whitespace are now merged into a single highlight block
if the gap between them contains fewer than 5 non-word characters.
This creates more readable diffs and closely matches GitHub's own diff
display.

In Chinese, the correct term for the computer action "paste" is 粘贴
(zhān tiē). The original translation used 粘帖, which contains a very

means a note or invitation) instead of the correct character 贴 (which

Problem: invalid pointer casting in string_convert() arguments
Solution: Use a temporary local int variable (James McCoy)
string_convert()/string_convert_ext() accept an "int *lenp" parameter,
however a few call sites were taking the address of a possibly larger
type (long, size_t) and casting it as an int * when calling these
functions.
On big-endian platforms, this passes the (likely) zeroed high bytes of
the known length through to string_convert(). This indicates it received
an empty string and returns an allocated empty string rather than
converting the input. This is exhibited by test failures like
From test_blob.vim:
Found errors in Test_blob2str_multi_byte_encodings():
command line..script src/testdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 2: Expected ['Hello'] but got ['']
command line..script src/testdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 3: Expected ['Hello'] but got ['']
command line..script srctestdir/runtest.vim[636]..function RunTheTest[63]..Test_blob2str_multi_byte_encodings line 6: Expected ['Hello'] but got ['']
Instead, use a temporary local int variable as the in/out variable for
string_convert() and assign the result back to the larger typed length
variable post-conversion.

Problem: Vim could use the VisualNOS highlight group when not connected

Solution: Always highlight visual selections with Visual when not
connected to an X server (Shane Harper)
When Vim is running with X11 support it chooses between the Visual and
VisualNOS highlight groups for a visual selection based on whether it
believes it owns the X selection. According to :help hl-VisualNOS,
VisualNOS should only be used by the X11 GUI or when using the
xterm-clipboard feature, however, prior to this commit Vim could choose
VisualNOS when a clipboard provider was used, even when Vim was not
connected to an X server.

no way for an external process to initiate a connection

Unix domain socket. When a client connects, a new
channel is automatically created and passed to a
