Problem: blob to string conversion can be improved
Solution: Compute the output size up front and use a single alloc plus
mch_memmove() (Yasuhiro Matsumoto).
Replace per-byte ga_append/snprintf loops with bulk allocation and
mch_memmove in three hot paths: blob2string() (used by string()),
string_from_blob(), and the UTF-16/UCS path of f_blob2str(). For a
16 MiB blob, string(blob) is ~28x faster and blob2str() is ~2x faster.
Benchmark (16 MiB blob, 5 iterations, total seconds):
| | Before | After | Speedup |
|---|---:|---:|---:|
| `string(blob)` | 6.422 | 0.225 | 28.5x |
| `blob2str(b)` | 0.504 | 0.265 | 1.90x |
| `blob2str(b, {encoding: 'utf-8'})` | 0.507 | 0.282 | 1.80x |
| `blob2str(b, {encoding: 'utf-16le'})` | 0.407 | 0.202 | 2.01x |

Problem: blob encoding can be improved
Solution: Speed up blob encoding by avoiding per-byte ga_append()
(Yasuhiro Matsumoto)
Replace the per-byte ga_append loop in the VAR_BLOB branch of
json_encode_item() with a single ga_grow for the worst case
(2 + 4 * blen) and direct writes through a local pointer. Also
read blob bytes through a local char_u* instead of going through
blob_get() for each byte.

Problem: popup: opacity blend may leaks white bg color
Solution: Add cterm color blending for 256 color terminals, use
COLOR_INVALID() macro to check for invalid color
(Yasuhiro Matsumoto)
When a textprop highlight only set gui=undercurl/guisp (no fg/bg), the
CTERMCOLOR sentinel was treated by hl_blend_attr() as a real near-white
color, leaking white bg onto textprop-covered cells under an opacity
popup or pum. Add a cterm color blending path that approximates blends
in the xterm 256-color palette using the gui RGB when available, so
opacity now has a visible effect even without 'termguicolors' (in
256-color terminals). Below 256 colors the blend is skipped.
Also document the requirement (GUI, 'termguicolors', or 256-color
terminal) and update existing pumopt/popupwin opacity screendumps to
reflect the new blended output.

Problem: In a vertical split where the pum overlaps the windows vsep column,
background draws (vsep at cursor row, status line,
redraw_vseps, idle ins_redraw) can write into cells that are

those cells while pum_will_redraw is set.
Solution: In skip_for_popup(), also skip cells under a visible pum when
the current draw is not the pum itself (screen_zindex
POPUPMENU_ZINDEX). Exclude the wildmenu pum (MODE_CMDLINE):
while the cmdline grows, pum_row is briefly stale and

Solution: Remove the PTY-specific per-line splitting in

Problem: A <Cmd> command in Insert mode can edit the current buffer,
e.g., with setline(). That edit appends to the current undo
block, but Insert mode does not know that the cursor line may
need to be saved again before the next typed edit. If the next
typed edit is a <BS> at the start of a line, it can join away
the line that was changed by the <Cmd> command before Insert
mode saves that updated line. The newest undo entry can then
still refer to the joined-away line, so undo sees a range past
the end of the buffer and fails with E438.
Solution: If a <Cmd> command in Insert mode changes the buffer, set
ins_need_undo so stop_arrow() refreshes Insstart. This lets
the next edit properly decide whether a new undo entry is
needed (Jaehwang Jung)

Problem: Several issues around the tabpanel scrollbar:
1. :set tabpanelopt= completion did not offer "scroll" and
"scrollbar".
2. gt/gT and other tab switches did not update the scrollbar
thumb; the current tab could move outside the visible
panel range without the view following.
3. When tpl_scroll_offset was at its maximum, the thumb's
bottom did not reach the last screen row due to integer
truncation in thumb_top (e.g. 31 tabs on 24 rows + :tablast
left a one-row gap).
4. For align:right the scrollbar was drawn on the panel's
left edge (adjacent to the buffer area), which breaks the
common convention that a vertical scrollbar sits on the
right.
Solution: - Add "scroll" and "scrollbar" to the 'tabpanelopt' expansion
list. Cover the completion in test_options.vim and extend
util/gen_opt_test.vim with the new valid/invalid values;
drop the now-redundant acceptance test from
test_tabpanel.vim.
- In draw_tabpanel(), remember the last-drawn curtab and,
when it changes, adjust tpl_scroll_offset so curtab_row
falls inside [offset, offset + Rows). Mouse wheel and
drag leave curtab unchanged, so the user's chosen offset
is preserved.
- In draw_tabpanel_scrollbar(), compute thumb_top as
(Rows - thumb_height) * tpl_scroll_offset
/ (tpl_total_rows - Rows), mirroring the mapping already
used by tabpanel_drag_scrollbar(). This guarantees the
thumb's bottom reaches the last row at the maximum offset.
- In draw_tabpanel(), place the scrollbar at the tabpanel's
right edge for both align:left and align:right (previously
align:right put it on the panel's left edge next to the
vertical separator). For align:right this means the
scrollbar now sits at the screen's right edge.
- Update :h tabpanel-scroll to describe the new, align-
independent placement.
- Add Test_tabpanel_scrollbar_follows_curtab() and
Test_tabpanel_scrollbar_reaches_bottom() to exercise the
regressions fixed by items 2 and 3.

The MSVC and MinGW C runtimes do not provide strptime(), so the
strptime() builtin was unavailable on Windows. Port NetBSD's

file. Windows-specific adjustments: English-only locale tables, the
fromzone()/tzalloc() path is stubbed out (no IANA tzfile loader on
Windows), and tm_gmtoff / tm_zone stores are elided.
Also call tzset() before mktime() in f_strptime() so changes to \$TZ
are honored.

Problem: tabpanel: double-click opens a new tab page
Solution: Do not create a new tab page when using a double click

The tabpanel click handler inherited the tabline behavior where a
double-click opens a new, empty tab page. Unlike the tabline, the
tabpanel has no "empty area": every row maps to some tab, so this
fires on any double-click in the tabpanel and can generate stray
empty tabs. The behavior is also not documented for the tabpanel.

and fall through to the regular tab-switch path instead. The

Problem: tests: Test_error_callback_terminal is flaky on macOS
Solution: Use WaitForAssert() to make it more reliable

term_wait() only waits for terminal screen updates and does not
guarantee that the err_io 'pipe' callback has fired, so on macOS
the assert_match() against g:error frequently runs before sh has
written "sh: XXXX: not found", causing the test to flake.
Replace term_wait() + assert_match() with WaitForAssert() so each
assertion polls until the callback delivers the expected output.
Also defer sending "exit" until the stderr message has been seen,
to avoid losing the stderr write to the exit race.

Even though we unset HOME, we can see via scriptnames that user files
