Problem:
No way to handle a "tab moved" event.
Use-case: tabline plugins may cache tab labels, and need to know when to
invalidate their cache.
Solution:
Add a `TabMoved` event that triggers whenever tabs are reordered via `:tabmove`
or via mouse click-and-drag.
Problem:
After closing and reopening Neovim, ]' and [' fail with E92: Buffer 0
not found for marks restored from ShaDa. Direct jumps like 'a work
because mark_get_local() rewrites fnum before returning, but ]' uses
getnextmark() which does not, leaving fnum = 0.
Solution:
Set .fnum = buf->b_fnum when restoring local marks from ShaDa.
Problem: with a float focused and the target buf only shown in the
last non-float window, do_buffer_ext goes down the buf != curbuf
path. close_windows can't touch the last non-float, b_nwindows stays
> 0, close_buffer is skipped, returns OK silently.
Solution: if a non-float still holds buf after close_windows, jump
into it and recurse. Then buf == curbuf and the existing replacement
path takes over.
Problem:
There is a lot of overlap between terminal and prompt buffer, but no
easy way to limit the number of lines kept above the prompt to prevent
performance and other issues. This is desirable for both example
use cases in current documentation, chat UI and repl/shell plugins.
Solution:
Use existing 'scrollback' option to limit prompt-buffer lines
as well.

Problem:
API clients cannot query the tab-local value of 'cmdheight'.
Solution:
Allow nvim_get_option_value() to accept { tab = <tab-ID> } for 'cmdheight'.
Problem: matchfuzzy() can crash on long multi-word patterns.
Solution: Clamp pat_chars to maxMatches and stop before calling
match_positions() when the buffer is full (glepnir).

Define `:packupdate` and `:packdel` as separate commands instead of a
unified `:pack {subcommand}` because the semantics between the two
commands vary differently enough that it doesn't make sense to combine
them. Additionally, `:pack! update/del` looks bad.

Problem:
Using the `DiffTool` plugin (e.g. through `nvim -d ...` or `:DiffTool
<file1> <file2>` fails if a space is in one of the paths. This occurs
because the `diff` wraps the paths with quotes (`'`) if space
characters are present, which the line diff regex fails to parse.
Solution:
Update regex to handle quoted paths by matching the string within the
quotes, if it exists.
Problem:
- Configuring the height of one of the message targets to 1 is
recognized as 100% of 'lines'.
- Cmdline is expanded for message exceeding 'cmdheight' even if the
configured height is smaller than or equal to 'cmdheight'.
Solution:
- Recognize a height of 1 as absolute; a decimal number smaller than 1
is taken as a fraction of 'lines' (replace 1 with 0.999 for the old
behavior).
- Don't expand the cmdline if the configured height doesn't allow it.
Problem:
On "arm clang unittest" CI job, `make unittest` sometimes fails with
lots of these messages:

Solution:
Update filter_complex_blocks.
Problem:
Many color schemes assume the Comment hl group is dim text and use it
for secondary text, decorations, or parts of UI. This is true for many
color schemes but not all.
Solution:
Introducing a new highlight group with a more specific meaning, similar
to Underlined or Ignore.
The new group links to Comment by default so the behavior is unchanged
for color schemes that don't define it.
Problem:
The Lua test harness still ran through standalone -ll mode, so tests
depended on the low-level Lua path instead of the regular Nvim Lua
environment. That also meant os.exit() coverage had to carry an ASAN
workaround because Lua's raw process exit skipped Nvim teardown and let
LeakSanitizer interfere with the observed exit code.
Solution:
Run the harness and related fixtures with nvim -l. Patch os.exit() in
the main Lua state to exit through getout(), so scripts observe normal
Nvim shutdown while standalone -ll remains available for generator-style
scripts. As a consequence, the startup test can assert os.exit() without
disabling leak detection.

Problem:
When using prompt_appendbuf with multi-element list,

Problem: the bookmarks list can have duplicate entries, more often
in win32 (due to mixed slashes and capitalization) and when
g:netrw_keepdir=0 (which could introduce relative paths).
Duplicate entries could be: C:\foo\BAR\baz.file
c:\foo\bar\baz.file
c:/foo\BAR/baz.file
BAR/baz.file
Solution: Normalize the paths and make sure they are always absolute

Problem: - "bufwrite" message identifier is encoded in the message ID
of a "progress" kind message (since ff68fd6b); UI2 does not
allow routing by message ID.
- No documented way to set a default message target for all
but a few kinds (without copying all of |ui-messages| kinds
to cfg.msg.targets).
- A user adding a message route for the documented empty ""
kind can result in unexpected behavior.
- Showing duplicate message (x) indicator in msg and cmd
targets simultaneously is unsupported.
- Manually triggering CursorMoved autocommand to add matchparen
highlighting in the cmdline.
Solution: - Match cfg.msg.targets keys as Lua pattern to a message ID.
- Recognize "default" as key in cfg.msg.targets, drop the
undocumented cfg.msg.target field.
- Don't try to get configured target for "" message kind/trigger.
- Maintain msg indicator virtual text for the cmd and msg target.
- Add matchparen highlighting by directly calling the Lua module
(possible since b813c7e0).
Problem: 'title' is updated when changing the name of a non-current
buffer with nvim_buf_set_name().
Solution: Set RedrawingDisabled when renaming the buffer.
Problem: Message redirection column for captured output is not reset
after :echon since (4260f73, e63346df).
Solution: Ensure msg_ext_append is set before the kind with :echon.
Problem: some functions can be run from the sandbox

Problem:
Regression from c822a2657c: `vim.wait(0)` does not call `loop_poll`,
so `vim.wait(1)` is needed to "yield" from Lua.
Solution:
- Ensure that `vim._core.loop_poll()` is always called, even when `time=0`.
- Document how to interrupt Lua code (ctrl-c).

Problem: <Esc> in a Select-mode tabstop leaves the session and highlight active.
CursorMoved isn’t triggered since the cursor doesn’t move.
Solution: use ModeChanged (s:n) instead. Defer with vim.schedule() to avoid transient
s:n from jump().
Problem: The four pointer-resolution loops in u_read_undo() lack
an i != j guard, so a header whose uh_next.seq equals
its own uh_seq resolves uh_next.ptr to itself. On
buffer close, u_freeheader() sees uhp->uh_next.ptr !=
NULL and skips updating b_u_oldhead, so u_blockfree()
dereferences the freed header on the next iteration.
The same pattern applies to uh_prev, uh_alt_next and
uh_alt_prev. A crafted .un~ file in the same directory
as a text file can trigger the use-after-free and
subsequent double-free when the buffer is closed.
(Daniel Cervera)
Solution: Add an i != j guard to each of the four resolution
loops, matching the guard already present in the
duplicate-detection loop above.

Problem: #39625 retained `matchparen.vim` as a shim that sources the new
`matchparen.lua` entrypoint, which is redundant since Lua runtime/plugin
files are sourced automatically and incurs startuptime cost solely for
the sake of not touching the tests.
Solution: Remove the shim and `source` the Lua plugin in directly in
tests.

Problem: Trying to execute code action on an active plugin without
updates leads to nothing. It is more useful if code actions "do
something" on a bigger portion of the confirm buffer.
Solution: Suggest "delete" code action even for active plugins. Trying
to execute it will first show a confirmation buffer with relevant
warning of why this might be not a good idea. Confirming will delete
a plugin.
Problem:
- Empty ranges have different `<`, `<=`, `has` and `intersect` semantics compared to regular ranges.
- `to_inclusive_pos` assumes that the end position of a range is exclusive, which is not true for empty ranges
Solution:
Special case empty ranges in these operations.
Problem:
When `:!` writes shell output to a buffer, write_output() splits on `\r`, `\n`,
and `\r\n`, replacing the terminator byte with NUL. For a binary-mode buffer
this is wrong: `\r` should be preserved verbatim, not treated as a line
terminator. This wrong behavior causes a file like `\r\n` round-trips through
`:%!cat` to `\n`.
This was masked when 'shelltemp' was enabled, because output went through a temp
file and the regular file I/O path handled binary-mode correctly. Switching the
default to 'noshelltemp' exposed the bug, since output is now piped directly
into write_output().
Solution:
In `write_output()`, skip the `\r` and `\r\n` splits for a binary-mode buffer;
only split on `\n`.
Problem: read_compound() in spellfile.c computes the size of the regex
pattern buffer using signed-int arithmetic on the attacker
controlled SN_COMPOUND sectionlen. With sectionlen=0x40000008
and UTF-8 encoding active the multiplication wraps to 27 while
the per-byte loop writes up to ~1B bytes, overflowing the heap.
Reachable when loading a crafted .spl file (e.g. via 'set spell'
after a modeline sets 'spelllang'). The cp/ap/crp allocations
have the same int + 1 overflow class (Daniel Cervera)
Solution: Use type size_t as buffer size and reject values larger than
COMPOUND_MAX_LEN (100000). Apply the same size_t treatment to
the cp/ap/crp allocations.
