Wintty 1.0.0-rc.9 release notes

Highlights

• All editions: Set wintty as your default terminal and Windows hands it every launch - links, scripts, other apps - so everything that opens a terminal opens here.
• All editions: Programs can mark a tab with their status, and editors and agents do: the marks reach the tab strip and follow the program's state.
• All editions: Send feedback without leaving the app. The window finds you where you are, replies arrive as toasts, screenshots can be cropped and marked up, and the support form copies your address with one click.
• All editions: A program's soft reset works the way the standard says, a full reset restores your palette too, and private modes a terminal does not support report themselves as reset.
• All editions: Resizing keeps the shell and the terminal in step, so a busy program no longer keeps drawing at the old size, and a window you bring back keeps the frame on screen instead of flashing to its background.
• Sponsor and Pro: Windows on ARM is built and served alongside the x64 editions, as an experimental ARM64 build on its own channels.
• Pro and Pro Legacy: Your tabs and panes now live in the session daemon by default, so they survive an app restart. Sessions have names - rename from the app or the CLI - a revived pane reattaches its own session, and a ghosted pane is kept until you say otherwise.
• Pro and Pro Legacy: Terminal surfaces share one graphics device for the whole app instead of each making its own, so windows and tabs open faster. Every surface was also building its renderer twice and quietly losing one of the two; that is fixed. When the graphics driver goes away - a reset, an unplug, a remote session rehosting - panes rebuild on a fresh device and keep working instead of freezing or going dark. On Pro Legacy's DirectX 11 renderer the shared device makes opening a window or tab several times faster.
• Pro: Motion flows. The focus border flies around the panes as focus moves, the tab you switch to slides into place, a split's new pane grows out of the divider and settles without crossing its neighbour, and the Animations setting stops every movement at reduced. A split animation that loses its finish now lands within a fixed bound instead of holding the pane mid-flight forever.
• Pro: The tab status panel arrives: a marks strip, a hover panel, stacked state edges and a count chip, so a program's status lives on its tab, announced as it changes.

Fixes

• All editions: Copied output keeps its shape - blank cells and erased backgrounds survive the copy, and trailing blank rows are no longer trimmed away.
• All editions: Cursor addressing is origin-relative where the standard says so, and backspace and cursor-back stop at the left margin.
• All editions: Clicks with any mouse button are tracked correctly, not just the primary ones.
• All editions: The first switch to a tab you just opened draws its content instead of a blank pane.
• All editions: The window's frame and the tab strip follow the window theme as one decision: a light window theme no longer paints a dark strip or frame, and a theme switch leaves no half-updated frame behind.
• All editions: The tab strip repaints only what changed, its ink re-derives when the window theme lands, the vertical strip paints in the window's theme, a non-finite tint opacity is rejected before it can blank the ground, and cancelling a theme preview restores your palette exactly.
• All editions: The feedback window keeps your draft when you switch away or cancel; a failed send keeps its text, says why, and offers retry; attachments are checked and capped on the way out.
• All editions: The update entries in the command palette bind in every window, not only the first one to open.
• All editions: A split's first keystrokes can no longer arrive before the new pane is ready, and the block caret stays on the prompt's trailing blank instead of overflowing it.
• All editions: The Animations setting accepts quoted values, and a deleted setting no longer resets its neighbours.
• All editions: A forwarded wintty:// link routes through the same launcher as a direct launch.
• Pro: The title row's pills no longer overlap the feedback button or the tab strip.
• Pro: On hardware without Direct3D feature level 12_0, Pro now shows an error that says why it cannot start and where to get Pro Legacy instead of closing silently.
• Pro and Pro Legacy: Fixed a crash in the tab status area, where a background refresh could race the window's own work.
• Pro and Pro Legacy: When the session daemon takes a moment to answer, the window you opened keeps its place: your terminal is ready first and the daemon's windows join your tabs afterwards without taking the screen.
• Pro and Pro Legacy: A new tab renders at the width it was opened at from the first frame, and new tabs receive a NO_COLOR set in the environment you launched from, including tabs that start from a pre-warmed shell.
• Pro and Pro Legacy: Work started through a helper that exits right away, such as start /b in cmd, is no longer recognized as running; to keep such work running, ghost the pane with Ctrl+B, then D, instead of closing it.
• Pro Legacy: The legacy renderer runs on the app's own device surface and no longer renders a zero-size pane.
