Problem:
Default statusline doesn't show progress status.
Solution:
- Provide `vim.ui.progress_status()`.
- Include it in the default 'statusline'.
How it works:
Status text summarizes "running" progress messages.
- If none: returns empty string
- If one running item: "title: percent%"
- If multiple running items: "Progress: N items avg-percent%"
Problem:
Checking the extension of a file is done often, e.g. in Nvim's codebase
for differentiating Lua and Vimscript files in the runtime. The current
way to do this in Lua is (1) a Lua pattern match, which has pitfalls
such as not considering filenames starting with a dot, or (2)
fnamemodify() which is both hard to discover and hard to use / read if
not very familiar with the possible modifiers.
vim.fs.ext() returns the file extension including the leading dot of
the extension. Similar to the "file extension" implementation of many
other stdlibs (including fnamemodify(file, ":e")), a leading dot
doesn't indicate the start of the extension. E.g.: the .git folder in a
repository doesn't have the extension .git, but it simply has no
extension, similar to a folder named git or any other filename without
dot(s).
Problem: Vim may freeze if setcmdline() is called while the wildmenu or
cmdline popup menu is active (rendcrx)
Solution: Cleanup completion state if cmdbuff_replaced flag has been set

Introduce _provider_foreach to iterate over all matching provider
capabilities for a given LSP method, handling both static and dynamic
registrations. Update diagnostic logic and tests to use the new
iteration approach, simplifying capability access and improving
consistency across features.
Problem
Unlike inlay hints, code lenses are closely related to running commands;
a significant number of code lenses are used to execute a command (such
as running tests). Therefore, it is necessary to provide a default
mapping for them.
Solution
Add a new default mapping "grx" (mnemonic: "eXecute", like "gx").
Problem:
Mouse popup menus (right-click context menus) do not respect the
'pumborder' option and could overflow screen boundaries when borders
were enabled near the edge.
Solution:
- Remove the mouse menu exclusion from border rendering.
- Add boundary check to shift menu left when border would exceed screen
width, ensuring complete visibility of menu content and borders.
Problem: Entering the pager is scheduled to avoid errors while in the
cmdwin. Meanwhile the current window is used as a condition to
detect an active pager.
Solution: Keep track of when the user is in the pager (or entered the
cmdwin while the pager was open).
Problem:
No way to iterate configs. Users need to reach
for `vim.lsp.config._configs`, an internal interface.
Solution:
Provide vim.lsp.get_configs().
Also indirectly improves :lsp enable/disable completion
by discarding invalid configs from completion.
Problem:
If buffer update callbacks poll for uv events during terminal scrollback
refresh, new output from PTY process may lead to incorrect scrollback.
Solution:
Don't poll for output to the same terminal as the one being refreshed.
Problem:
`nvim_echo(…, {id=…})` accepts user-defined id as a string or integer.
Generated ids are always higher than last highest msg-id used. Thus
plugins may accidentally advance the integer id "address space", which,
at minimum, could lead to confusion when troubleshooting, or in the
worst case, could overflow or "exhaust" the id address space.
There's no use-case for it, and it could be the mildly confusing, so we
should just disallow it.
Solution:
Disallow *integer* user-defined message-id.
Only allow *string* user-defined message-id.
Problem:
nvim_get_option_value with "filetype" set silently returns incorrect
defaults if autocommands are blocked, like when they're already running.
Solution:
Allow its FileType autocommands to nest: `do_filetype_autocmd(force=true)`.
Also error if executing them fails, rather than silently return wrong defaults.
Endless nesting from misbehaving scripts should be prevented by the recursion
limit in apply_autocmds_group, which is 10.
Problem:
On windows, if a drive-relative path doesn't contain a slash,
`path_to_absolute` can't split out the relative component, causing
expansion to fails. e.g., `c:` `c:.` `c:..` `c:foo.md`
Solution:
For these cases, we can pass letter and colon to `path_full_dir_name`.
Notably, `..` is included as well.
if that relative path exists, it can be expanded correctly.
Problem:
When `to_vim_value[info.metatype](info, value)` is called, a list value
such as `{'eob:a'}` is treated like a map, which generates `1:eob:a`.
Note: commands like `:lua vim.opt.wildmode={'longest:full'}` are not an
issue because only cases harcoded in `key_value_options` have metatype `map`.
Solution:
Check for array type and use the same logic as in array metatypes.
Problem:
Right-click menu fails with E335 when using V in Insert mode (after
i_ctrl-o). The mode detection checks restart_edit before VIsual_active,
incorrectly selecting Insert mode binding even when Visual mode is
active.
Solution:
Check Visual mode before Insert mode, to match get_menu_mode() priority
order.
Problem:
When code lens is enabled, `on_attach` is executed, but it does not trigger a redraw. Another event, eg, moving the cursor, is required to trigger a redraw and execute the decoration provider's `on_win`.
Solution:
Trigger a `redraw` after each request is completed.
Problem:
"[Process exited]" is implemented in C with anonymous namespace
and users have no way to hide it.
Solution:
- Handle "TermClose" event in Lua.
- User can delete the "nvim.terminal" augroup to avoid "[Process exited]".
Problem:
Applications running inside :terminal that use DEC private mode 2026
(synchronized output) to batch screen updates get garbled rendering.
Neovim's embedded libvterm does not handle mode 2026, so the
synchronization sequences are ignored and intermediate screen states
leak through as visual corruption.
Solution:
Add mode 2026 support to libvterm's state machine and wire it through
to terminal.c. When an application enables mode 2026, invalidation of
the terminal buffer is deferred until the application disables it,
causing all accumulated screen updates to flush as a single
atomic refresh.
* fix(terminal): harden sync output redraw gating
Problem:
The initial mode 2026 implementation gated invalidate_terminal()
but missed three other redraw paths: term_sb_push/term_sb_pop
bypassed the gate by directly adding to invalidated_terminals,
refresh_timer_cb could fire mid-sync flushing partial state, and
the 10ms timer delay after sync-end left a window for stale
repaints.
Solution:
- Gate term_sb_push/term_sb_pop during synchronized output
- Skip syncing terminals in refresh_timer_cb
- On sync end, schedule a zero-delay full-screen refresh via
sync_flush_pending flag in terminal_receive()
- Add news.txt entry for mode 2026 support

* test(terminal): add vterm unit tests for mode 2026
Add unit-level tests for synchronized output (mode 2026) to
vterm_spec.lua, covering settermprop callbacks and DECRQM
query/response.

* fix(terminal): address review feedback for mode 2026
- Use multiqueue_put(main_loop.events) instead of restarting the
global refresh timer on sync end, to avoid affecting other
invalidated terminals.
- Add screen:expect_unchanged() to verify screen doesn't update
during sync mode.
- Merge buffer-lines test into existing test.

Problem:
Completion preview always assumes plain text, ignoring LSP documentation "kind".
Solution:
Pass markup kind from completion item to info window, or fallback to PlainText.
Problem: 'jumpoptions' "view" doesn't remember skipcol and may lead to
glitched display with 'smoothscroll'.
Solution: Save skipcol in the mark view. Also make sure skipcol doesn't
exceed line size.
vim-patch:9.2.0174: diff: inline word-diffs can be fragmented
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.

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: autocmds that switch windows may cause them to remain with
w_locked set, preventing them from being closed longer than
intended.
Solution: Unset w_locked in the window where it was set (Sean Dewar).
closes: vim/vim#19716bae31c35bb
Also move alist_add_list's ga_grow inside the if block, so it's only called when
check_arglist_locked is OK, like Vim.
I also notice a redundant return at the end of the block; could be useful if
more code is added later, so I'm leaving it.
Problem:
No way to disable progress messages in cmdline message area. If
a third-party plugin handles Progress events + messages, the user may
not want the "redundant" progress displayed in the cmdline message area.
Solution:
Support "progress:c" entry in 'messageopts' option.
Problem:
The `float` field of vim.diagnostic.config can be a function,
but diagnostic.open_float() does not handle it correctly.
Solution:
Add handling for it in open_float().
Problem: nvim_open_tabpage's "enter" argument is optional, which is inconsistent
with nvim_open_win.
Solution: make it a (non-optional) positional argument, like nvim_open_win.
Also change "enter"'s description to be more like nvim_open_win's doc.
Problem: "after" in nvim_open_tabpage is inconsistent with how a count works
with :tab, :tabnew, etc. Plus, the name "after" implies it's inserted after that
number.
Solution: internally offset by 1. Allow negative numbers to mean after current.
Hmm, should we even reserve sentinels for after current? Callers can probably
just use nil...
- Cleanup, remove redundant comments, add more tests.
- Enhance win_new_tabpage rather than create a new function for !enter, and use
a different approach that minimizes side-effects. Return the tabpage_T * and
first win_T * it allocated.
- Disallow during textlock, like other APIs that open windows.
- Remove existing win_alloc_firstwin error handling from win_new_tabpage; it's
not needed, and looks incorrect. (enter_tabpage is called for curtab, which is
not the old tabpage! Plus newtp is not freed)
- Fix checks after creating the tabpage:
- Don't fail if buf wasn't set successfully; the tab page may still be valid
regardless. Set buffer like nvim_open_win, possibly blocking Enter/Leave
events. (except BufWinEnter)
- tp_curwin may not be the initial window opened by win_new_tabpage. Use the
win_T * it returns instead, which is the real first window it allocated,
regardless of autocmd shenanigans.
- Properly check whether tab page was freed; it may have also been freed
before win_set_buf. Plus, it may not be safe to read its handle!
Problem:
"Sorry" in a message (1) is noise, and (2) actually reduces the clarity
of the message because the titlecasing of "Sorry" distracts from the
actually important part of the message.
Solution:
Drop "Sorry" from messages.
Problem: termdebug :Break does not support `thread` and `if` arguments
Solution: extend :Break and :Tbreak to accept optional location, thread
{nr}, and if {expr} arguments (Yinzuo Jiang).

Problem: tests: a few termdebug tests are flaky; test_termdebug_basic()
and test_termdebug_config_types() may fail if there is too
much load
Solution: Set g:test_is_flaky
Only include:
- mark Test_termdebug_basic() as flaky in oldtest termdebug plugin tests
The Test_termdebug_config_types() part does not apply here.

Problem: tests: termdebug test may fail and leave temp file around
(Dominique Pellé)
Solution: only run balloon_show() if the function exists, validate
termdebug is running using the g: termdebug_is_running var,
use defer to delete temporary files
Only include:
- guard balloon_show() in the termdebug plugin
- wait for g:termdebug_is_running in Test_termdebug_basic()
The remaining upstream test cleanups do not apply here.

Problem: #38316 is a bit aggressive; we need not always leave Terminal mode if
autocmds put us in a different terminal.
Solution: don't skip entering; let terminal_check_focus handle whether we should
immediately leave.
Problem:
`K` in help files may fail in some noisy text. Example:
(`fun(config: vim.lsp.ClientConfig): boolean`)
^cursor
Solution:
- `:help!` (bang, no args) activates DWIM behavior: tries `<cWORD>`,
then trims punctuation until a valid tag is found.
- Set `keywordprg=:help!` by default.
- Does not affect `CTRL-]`, that is still fully "tags" based.
Problem: heap-use-after-free possible when entering Terminal mode if
autocommands close the terminal.
Solution: set the refcount. Skip to the end if we must close the terminal.
