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'.
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:
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: vim.ui_attach() callback for nvim_echo() call that spoofs an
internal message kind is executed in fast context.
Solution: Set msg_show callback |api-fast| context dynamically at
external message callsites, and for internal list_cmd",
"progress" and "shell*" messages.
Problem:
When using prompt_appendbuf with multi-element list,
the first item is concated and rest replace the prompt instead of
inserting the lines before the prompt.
Solution:
Concat first element with replace_buf and insert the rest of the list
with set_buffer_lines.

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:
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: #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: No test that "abbr" in customlist completion is shown in pum.
Solution: Add some "abbr" fields to the existing test (zeertzjq).

Problem: 'findfunc' can't return extra info for cmdline completion
(Maxim Kim).
Solution: Handle 'findfunc' return value in cmdline completion like that
of "customlist" functions (zeertzjq).

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:
When showing the :connect menu, it is useful to know which servers
are most-recently active. But we don't have a good way to detect that.
Solution:
- Introduce `v:useractive`.
- Include this timestamp in `serverlist({info=true})`.

Problem:
parser_gc() calls ts_parser_delete() but leaves the userdata pointer
pointing to freed memory. If the GC finalizer runs at an unexpected time
(e.g. inside nvim_buf_get_lines #39411), a stale pointer could cause a crash.
Solution:
- NULL out `*ud` after ts_parser_delete() in parser_gc()
- Update parser_check() to handle NULL with a clear error message,
guarding all parser methods against UAF

Problem:
For a given position, it is not easy to compare which of several other positions is closest to it.
Solution:
Add support for converting `vim.Pos` to a buffer byte offset.
This allows for sorting, e.g:
```lua
table.sort(positions, function(pos1, pos2)
return pos1:to_offset() < pos2:to_offset()
end
```
Or a binary search, e.g:
```lua
vim.list.bisect(positions, pos, { key = function(pos) return pos:to_offset() end })
```
Problem: Internal progress messages use the "nvim" source (since
ff68fd6b), plugins shouldn't be allowed to set the progress
message source to "nvim". The message ID used for internal
progress messages is not identifiable as such.
Solution: Disallow setting opts->source to "nvim" with nvim_echo().
Refactor msg_progress() and callees to bypass nvim_echo().
Prepend message id for internal progress messages with "nvim.".
Improve the vim.iter annotations with richer generics that track element and
tuple types through iterator pipelines, including multi-value stages and
list-specific methods.
Extend the LuaCATS parser and vimdoc generator so those richer generic classes
and overloads round-trip into the generated help. These annotations are only
supported by EmmyLua, so LuaLS still uses a broader fallback in _meta.lua.

Problem: Entering the pager fails if <ESC> is remapped to :fclose by user.
Solution: Avoid executing mappings with nvim_feedkeys() that closes expanded cmdline.
Problem:
UI tools and orchestration engines need more context than just raw
socket addresses from serverlist(). Without knowing if a server belongs
to the current instance or knowing its PID, UIs cannot display
meaningful options to users.
Solution:
- Added the `info=v:true` option to `serverlist()`.
- When `info` is requested, it implies `peer=true` and returns a list of
dictionaries (defined as `vim.ServerInfo`) with `addr`, `pid` and
`own`.
- Uses an RPC request to `getpid()` across the socket to fetch the
peer's actual process ID.

cmd is string.
Solution:
Returns "desc" field in nvim_get_commands.
`definition` is now empty when cmd is function type.

Problem:
When using `vim.list.unique` or `vim.list.bisect`, if the `key` function is
complex, it can degrade performance, because it is invoked on every comparison
Solution:
The `key` interface convention is designed specifically to address this issue;
performance can be improved by memoizing its results.
Also added the shorthand use of the field name string as the key.
Problem:
Nested workspace capabilities like workspace.fileOperations.didCreate and
workspace.textDocumentContent are not handled consistently for dynamic and
static registration provider lookup.
Solution:
Generate explicit registration-provider mappings from the LSP metadata and use
them when registering and querying capabilities. Add coverage for dynamic and
static nested workspace registrations.
