> `dark_shade`
> - custom symbols via `Shadow::symbol(...)`
> - custom effects via `Shadow::custom(...)`
>
> ```rust
> use ratatui::layout::Offset;
> use ratatui::style::Stylize;
> use ratatui::widgets::{Block, Shadow};
>
> let popup = Block::bordered().title("Popup").shadow(
> Shadow::dark_shade()
> .black()
> .on_white()
> .offset(Offset::new(2, 1)),

- [39c32c6](https://github.com/ratatui/ratatui/commit/39c32c6fa981c4b326bf2533100ac86b7be05eba) *(buffer)* Add cell diff options by benjajaja in [#1605](https://github.com/ratatui/ratatui/pull/1605)
>
> Problem:Escape sequences always cause a cell to count as "multiwidth",
> even when it doesn't render wider than one cell, or not as wide as the
> escape sequence would be computed as.
>
> Solution:Convert `skip:bool` to enum. Add enum option `ForceWidth` to
> force a cell width for diffing.
>
> When using the option, this also fixes some bug where diffing is not
> idempotent and causes a diff operation for `(symbol.len() - 1)` times.
>
> There are three new specific test cases:
>
> 1. Rendering hyperlinks by squeezing the escape sequence into the first
> cell and forcing the width to the unicode width of the text part.
> This is much easier to implement for a Link widget, as it would only
> need to get the unicode-width once and not iterate over graphemes
> like Spans must do.
> 2. Rendering hyperlinks by squeezing the opening sequence into the first
> cell with the first grapheme and forcing the width to that of the
> first grapheme. Then rendering each grapheme as usual. Then squeezing
> the closing sequence into the last cell with the last grapheme and
> forcing the width to that of the last grapheme.
> This is harder to implement for a Link widget, as it would have to
> iterate over graphemes with their width like Spans do.
> 3. Kitty image sequence with utf-8 placeholders, similar to 2 but with
> known constant grapheme widths.
>
> ### Link widget that leverages this
>
> https://github.com/benjajaja/tui-link
>
> 
>
> It would be cooler if we could just add something like `.link(url)` to
> `Span`s, because it would much simpler to insert some link and leverage
> all the Line/Text/Paragraph wrapping and whatnot. With a custom widget
> you need to take care of the `Area` where you'd want to render it, so
> it's not that clean. But we could iterate on this later, if even
> possible.

> This PR adds the following implementations of the From trait for Line
> and Text structs:
>
> - Implements From<&[T]> where T is Into\<Span> for Line, allowing using

- [5fc6ab8](https://github.com/ratatui/ratatui/commit/5fc6ab881aba8f0bad30f05730673a15ed64858f) *(core)* Support layout-cache in no_std environments by junkdog in [#2399](https://github.com/ratatui/ratatui/pull/2399)
> this enables "layout-cache" for no_std builds; it's meant for embedded
> environments, where the layout engine otherwise consumes all CPU,
> capping the framerate at around ~10fps. the same app can refresh 300-500
> times per second with layout cache enabled.
>
> i had to add `layout-cache = ["dep:critical-section"]` to all builds -
> it's pretty tiny and shouldn't leave a trace in std-builds. the
> alternative is to add an extra layer of features for layout-cache with
> std and no_std, but it pollutes the feature space.

- [9d9239a](https://github.com/ratatui/ratatui/commit/9d9239a702d8cd29ca321745901ddb56bff20f70) *(examples)* Add volatility-surface 3D visualization by floor-licker in [#2322](https://github.com/ratatui/ratatui/pull/2322)
> A design demonstration of a 3D volatility surface rendering using
> Braille canvas with interactive rotation and zoom controls. I built this
> for myself for an app I'm currently building but just wanted to share it
> with the community as well to inspire more 3D perspective terminal
> widgets in the future.
>
> ## Final Demo
>
> 
>
> ## Description
>
> Adds a new example demonstrating 3D visualization techniques in the
> terminal. There aren't many examples showing how to represent 3D objects
> in 2D terminal space so my goal is just to demonstrate more advanced
> Canvas and Braille rendering techniques for 3D graphics. The example
> visualizes an implied volatility surface which is a common financial
> visualization using interactive rotation and zoom controls. You can run
> the interactive demo for yourself with `cargo run -p volatility-surface`

> This commit adds filled area-chart rendering for both `Canvas` and `Chart`.
>
> You can now render a line and fill the area between that line and a baseline Y value, which helps highlight magnitude/volume trends.
>
> - In `Canvas`, use `FilledLine`.
> - In `Chart`, use `GraphType::Area` and set the baseline via `Dataset::fill_to_y(f64)`.
>
> The `f64` baseline is now configured on `Dataset` (not in `GraphType`), so `GraphType` stays a simple enum variant.
>
> Under the hood, line rasterization in canvas was refactored to share a reusable Bresenham point iterator, and `FilledLine` builds on that to paint vertical spans from each line point to `fill_to_y`.

>
> Fixes #2552
>
> This makes the `BarChart` constructors ignore empty groups, matching the
> existing `.data(...)` builder behavior. Without this,
>
> `BarChart::horizontal(Vec::<Bar>::new())` stores one empty group,
> proceeds into horizontal rendering, skips the bar loop, and then
> underflows when computing the group label row from `bar_y -
> self.bar_gap`.
>
> The fix normalizes constructor input through a shared `non_empty_groups`
> helper for `new`, `horizontal`, and `grouped`. Empty horizontal charts
> now render nothing instead of panicking, and constructor behavior is
> consistent with `.data(...)`.

- [6396b1c](https://github.com/ratatui/ratatui/commit/6396b1ce66721bda028ab3a54a6361cb98db7e6d) *(block)* Saturate block edge arithmetic by joshka in [#2488](https://github.com/ratatui/ratatui/pull/2488)
> ### Motivation
>
> - Block border and title layout used unchecked `u16` arithmetic in
> several places.
> - In debug builds that can panic on tiny or edge-case geometry; in
> release builds the same arithmetic wraps.
> - The original report came from merge-border rendering on tiny areas,
> but the same pattern appeared in title layout and spacing helpers as
> well.
>
> ### Description
>
> - Use saturating arithmetic in `Block::inner`, `render_sides`,
> `render_corners`, `titles_area`, and `vertical_space`.
> - Clamp rendered title widths to `u16` for layout arithmetic.
> - Replace unchecked title-width accumulation and cursor-advance math
> with bounded arithmetic.
> - Add debug-only regression tests covering empty areas, maximal padding,
> title-area edge cases, and very large title widths.
>
> ### Testing
>
> - Ran `cargo test -p ratatui-widgets block::tests`.

> this PR closes #2307 by preventing unnecessary diff updates for trailing
> cells when only style changes.
>
> This PR was generated by Claude, and validated by me.
>
> ## Summary
>
> This PR fixes a visual artifact bug where block borders would appear
> offset when rendered over a widget that had a foreground color style
> applied to the entire area.
>
> ## The Fix
>
> ```diff
> - if !next_trailing.skip && prev_trailing != next_trailing {
> + // Only emit update if the SYMBOL changed, not just the style.
> + // The style of hidden trailing cells is not visible, so style
> + // differences alone should not trigger updates that can cause
> + // cursor positioning issues on some terminals.
> + if !next_trailing.skip && prev_trailing.symbol() != next_trailing.symbol() {
> ```
>
> This aligns the code with the documented intent: only emit updates when
> the **symbol** (visible content) changes, not when only the style
> changes.
>
> ## Changes
>
> | File | Change |
> |------|--------|
> | `ratatui-core/src/buffer/buffer.rs:526-530` | Compare only symbol, not
> full cell |
> | `ratatui-core/src/buffer/buffer.rs:1376-1425` | Add regression test |
>
> ## Test Added
>
> ```rust
> #[test]
> fn diff_ignores_style_only_changes_in_trailing_cells() {
> // Verifies that trailing cells with same symbol but different style
> // do NOT generate diff updates
> }
> ```
>
> ## Why This Is Safe
>
> 1. **Trailing cells are hidden** - they are visually covered by the wide
> character
> 2. **Style is invisible** - the fg/bg color of a hidden cell has no
> visual effect
> 3. **Symbol changes still trigger updates** - if the symbol changes
> (e.g., from `" "` to `"x"`), the update is still emitted
> 4. **Aligns with documented intent** - the original comment says
> "non-blank content", not "different style"
>
> ## Related
>
> - The existing test `diff_clears_trailing_cell_for_wide_grapheme`
> verifies that symbol changes DO trigger updates
> - This fix complements that behavior by ensuring style-only changes do
> NOT trigger updates

> ### Motivation
> - Prevent arithmetic overflow when advancing `self.pos` for
> `CellDiffOption::ForcedWidth(NonZeroU16)` in
> `ratatui-core/src/buffer/diff.rs`, which could panic in debug or wrap in
> release and cause an iterator hang/DoS.
>
> ### Description
> - Replace the unchecked `self.pos += width.get().saturating_sub(1)` with
> a saturating addition via `self.pos =
> self.pos.saturating_add(width.get().saturating_sub(1) as usize)` to
> avoid overflow while preserving existing iterator semantics.
>
> ### Testing
> - Ran `cargo test -p ratatui-core buffer::diff --lib` and the buffer
> diff tests completed successfully (`10 passed, 0 failed`).

- [ce2c228](https://github.com/ratatui/ratatui/commit/ce2c22827a1fa9df9b97e22983cee3379327a832) *(examples)* Change flex example colors for MacOS default terminal by ffex in [#2211](https://github.com/ratatui/ratatui/pull/2211)
> Part of the fix for #1972
>
> ### Summary
>
> This fix introduces a function to check if we are in a terminal without
> truecolor(24-bit) and changes the default colors to appear fine of the
> flex example.
>
> ### Notes
>
> The function "is_true_color_supported” is an old problem and there is no
> common way to determine if a terminal supports or not the truecolor.
>
> This is the main reason why the function detects specifically the
> Terminal.app version before the Tahoe. If there are other known
> terminals with this problem, we can add it to this function.

>
> Fixes #2549.
>
> This prevents `Chart` from panicking when the Y axis is configured with
> exactly one label. The X-axis rendering path already skips label
> placement when fewer than two labels are provided; this applies the same
> guard to Y-axis labels before the spacing calculation divides by
> `labels_len - 1`.
>
> This also updates the `Axis::labels` docs so they describe the new
>
> behavior:fewer than two labels are not rendered instead of causing a
> panic.

> ## Summary
>
> Fixes #2545.
>
> This changes BarChart and Sparkline scaling to use a `u128` intermediate
> before division, then caps the scaled ticks at the drawable area. That
> prevents debug-build panics and release-build wrapping when public `u64`
> chart values are large.

> as discussed in
> https://github.com/ratatui/ratatui/pull/1605#discussion_r2933338973 -
> this brings back `Cell::skip` as a deprecated field in order to avoid

>
> ## `Cell::skip` vs `CellDiffOption`
>
> `CellDiffOption::ForcedWidth` takes precedence over `Cell::skip`, and
>
> `CellDiffOption::skip` is already skip - so `Cell::skip` can only

> @benjajaja maybe has some input too.
>
> ## PartialEq and Hash for `Cell::skip`
>
> `Cell::skip` is part of `PartialEq` and `Hash` as normal fields. another

> ## Summary
>
> This updates the terminal and setup docs to better match the rendering
> behavior Ratatui actually implements, while also making the docs.rs path
> clearer for application authors.
>
> The main docs changes are split into two commits:
>
> 1. `docs: align terminal docs with behavior`
> - align `Terminal`, viewport, frame, and flush docs with the real render
> pipeline
> - clarify the boundary between `Terminal::flush` and `Backend::flush`
> - improve examples for fullscreen, inline, and fixed viewport usage
> 2. `docs: improve terminal docs for app authors`
> - improve setup-path guidance across `ratatui`, `ratatui-core`, and
> backend crates
> - clarify viewport choice, escape hatches, and common edge cases
> - reduce duplication so crate-level docs explain choices while method
> docs hold detailed contracts
>
> A small follow-up also fixes the crate-doc heading hierarchy in
> `ratatui-core` and
> `ratatui-crossterm` so the generated READMEs no longer need
> `markdownlint-disable-next-line heading-increment` suppressions.
>
> ## Verification
>
> - `cargo test -p ratatui --doc`
> - `cargo test -p ratatui-core --doc`
> - `cargo test -p ratatui-crossterm --doc`
> - `cargo test -p ratatui-termion --doc`
> - `cargo test -p ratatui-termwiz --doc`
> - `cargo test --workspace --all-targets --no-run`
> - `cargo doc -p ratatui --no-deps`
> - `cargo doc -p ratatui-core --no-deps`
> - `cargo xtask format --check`
> - `cargo xtask readme --check`
>
> Note:`cargo doc -p ratatui-core --no-deps` still reports pre-existing
> warnings outside this pass in `layout` and `text` docs. The terminal-doc
> warnings introduced during this work were fixed.

> ## Summary
>
> - Improve `Terminal` Rustdocs to better explain typical app setup, the

> ## what and how
>
> this PR removes the `Vec<(u16, u16, &Cell)>` allocation in
> `Terminal::flush` when calling `Buffer::diff`. a new method,
> `Buffer::diff_iter` is instead used by `Terminal::flush`.
>
> the existing diff implementation has moved to the `BufferDiff` iterator.
>
> ## why (who cares?)
>
> it's the mice. on embedded devices, allocating a short-lived, contiguous
> block of up to 40-50kb is problematic due to heap fragmentation in
> combination with tiny heaps. the requirements for a full refresh over
> 1200 terminal cells is 37.5kb+vec growth padding, but since we're
> dealing with a contiguous block of memory, the actual memory
> requirements are considerably higher, depending on user-land allocation
> patterns.

### Miscellaneous Tasks
- [746e9c9](https://github.com/ratatui/ratatui/commit/746e9c9ca2370a2ff033fb082f765f4c32a629b4) *(build)* Add symlinks from each crate dir to root LICENSE by martinvonz in [#2370](https://github.com/ratatui/ratatui/pull/2370)
> AFAICT, each crate directory must have its own LICENSE file for it to
> become part of the published crate. This patch therefore adds LICENSE
> symlinks from each crate directory to the root LICENSE file. This
> matches what e.g. clap does (https://github.com/clap-rs/clap).
>
> Since ratatui-macros/LICENSE already exists and with different copyright
> holders than in the root LICENSE file, I left it unchanged.

- [0b03fe4](https://github.com/ratatui/ratatui/commit/0b03fe47f1a941fccf9dd694f2531157e312f330) *(toml)* Migrate from taplo to tombi by joshka in [#2501](https://github.com/ratatui/ratatui/pull/2501)
> ## Summary
>
> This migrates the repo's TOML tooling from
> [Taplo](https://github.com/tamasfe/taplo) to
> [Tombi](https://github.com/tombi-toml/tombi).
>
> The main motivation is maintenance and installability:
>
> - Ratatui previously used [Taplo](https://github.com/tamasfe/taplo) for
> TOML formatting.
> - Taplo's maintenance future has been uncertain; see
> <https://github.com/tamasfe/taplo/issues/715>.
> - Taplo's current release artifacts are not friendly to
> `cargo-binstall`, which means some setups fall back to building from
> source.
> - That source-build path is awkward for CI and was also a blocker while
> exploring a future Docker/devcontainer setup because of image size and
> install cost.
>
> [Tombi](https://github.com/tombi-toml/tombi) is actively maintained,
> publishes prebuilt binaries, and has a VS Code extension that lets us
> keep editor behavior aligned with CI.
>
> ## What Changed
>
> ### Tooling and CI
>
> - Replace `taplo` with `tombi` in `cargo xtask format`.
> - Use
> [`tombi-toml/setup-tombi`](https://github.com/tombi-toml/setup-tombi) in
> the formatting CI job.
> - Replace `.taplo.toml` with `tombi.toml`.
>
> ### Formatting policy
>
> - Keep the existing 100-column TOML line width.
> - Disable schema-driven top-level table ordering for `Cargo.toml`.
> - Disable the corresponding `tables-out-of-order` lint for `Cargo.toml`.
>
> Why disable Cargo schema ordering:
>
> - Tombi can order keys and tables according to schema metadata; see
> <https://tombi-toml.github.io/tombi/docs/comment-directive/tombi-value-directive/#format-rules-table-keys-order>.
> - The schema order moved sections like `[features]` below dependency
> sections.
> - That made feature-gated behavior harder to scan.
> - It also created noisy migration churn that was not central to the tool
> switch itself.
>
> Why disable the Cargo lint warning:
>
> - The VS Code warning came from Tombi's `tables-out-of-order` lint
> rather than from formatting.
> - Since we are intentionally preserving the existing Cargo manifest
> section order, we also disable that lint for `Cargo.toml` to keep
> diagnostics aligned with the formatter configuration.
> - Related docs:
> <https://tombi-toml.github.io/tombi/docs/configuration/>.
>
> ### Installation note
>
> - Tombi is better positioned for binary installs than Taplo today, but
> it is still not fully in the generic `cargo-binstall` /
> `taiki-e/install-action` path.
> - Relevant upstream context:
> - binary naming / generic installer compatibility:
> <https://github.com/tombi-toml/tombi/issues/1164>
> - crates.io publishing for `cargo-binstall` fallback:
> <https://github.com/tombi-toml/tombi/issues/1686>
> - earlier crates.io publishing discussion:
> <https://github.com/tombi-toml/tombi/issues/632>
> - In practice, this still leaves some rough edges around the generic
> Rust installer path, but Tombi already has usable prebuilt binaries and
> an official installer action, which is a better place for Ratatui than
> Taplo's current install story.
> - CI now uses
> [`tombi-toml/setup-tombi`](https://github.com/tombi-toml/setup-tombi)
> with a pinned version, which avoids the GitHub token path by not asking
> the action to resolve `latest` at runtime.
>
> ### Docs and editor setup
>
> - Update contributor docs to point to Tombi's repo, docs, and
> installation guide.
> - Note that the repo previously used Taplo and link the upstream
> maintenance discussion at <https://github.com/tamasfe/taplo/issues/715>.
> - Add VS Code extension recommendations for
> [`rust-lang.rust-analyzer`](https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer)
> and
> [`tombi-toml.tombi`](https://marketplace.visualstudio.com/items?itemName=tombi-toml.tombi).
> - Add committed VS Code workspace settings for shared repo defaults,
> mainly so the workspace can define formatter behavior that matches CI,
> including TOML formatter selection and nightly rustfmt args.
> - Add a dedicated formatting section to `CONTRIBUTING.md` covering Rust
> formatting, TOML formatting, nightly `rustfmt`, and the VS Code
> workspace override workaround.
>
> ## Why Commit VS Code Settings
>
> This PR adds committed VS Code workspace settings for shared repo
> defaults only.
>
> The goal is to:
>
> - recommend the expected extensions
> - make local editor formatting behave more like CI
> - avoid formatter drift between editor usage and the repo's checked-in
> tooling
>
> This is not intended to standardize everyone's full editor setup.
>
> ## Nightly rustfmt
>
> The repo already uses unstable rustfmt options in
> [`rustfmt.toml`](./rustfmt.toml), so formatting Rust code with `cargo
> xtask format` works best with nightly Rust. This is already how CI
> behaves.
>
> The docs now call this out more clearly:
>
> - install nightly if you want local formatting to match CI
> - the reason is to pick up the unstable formatting options configured in
> `rustfmt.toml`
>
> For contributors who cannot or do not want to install nightly, the docs
> also point to a workaround: use a personal VS Code workspace file with
> override settings instead of changing the tracked workspace config.
>
> ## Notes From Implementation
>
> - Tombi `v0.9.19` added config support to disable schema-defined
> ordering per schema, which let us preserve existing `Cargo.toml` section
> order cleanly.
> - The `tables-out-of-order` warning seen in VS Code came from Tombi
> lint, not formatting, so that needed a separate config change.
> - After disabling Cargo section ordering, the remaining TOML churn was
> much smaller and mostly mechanical.
