v0.2.6

Denial 0.2.6

This is a signed x86-64 public-alpha release of Denial.

• Source tag: v0.2.6
• Source commit: c094b7f0952b1b679dfb1eb7b84b4fb694cca36f
• Signing fingerprint: AE4108FA5E91E26BE0EE331E0F5B3AD16E023091
• Required packages: denial and denial-flutter-engine
• Optional live-development package: denial-ui-development

Added

• A compositor-integrated Impeller GLES path for Flutter's desktop-wide GBM
  atlas, including exact embedder FBO presentation, preserved partial damage,
  backdrop-filter support, native synchronization, and external-texture
  lifetime.
• Backdrop blur now has a configurable minimum effective window-opacity
  threshold, including an unconditional no-blur path for fully invisible
  windows.

Changed

• Impeller is now Denial's default Flutter renderer. The retained Skia/Ganesh
  path remains available through --flutter-renderer skia or the packaged
  DENIA_FLUTTER_RENDERER=skia session override.
• High-rate external-texture frames now preserve precise rotating-atlas
  damage, reuse cached layer-diff metadata for only the dirty textures, and
  avoid redundant Ganesh flushes when cached texture bindings need no GL work.
• Output ticks use maintained per-output window membership, and output-control
  snapshots are rebuilt only after state changes.
• The guided Arch setup now stops after trusting the release key and adding
  the signed repository. Package installation remains an explicit
  sudo pacman -Syu denial command.
• Signed tags now provide package and user-visible runtime versions without a
  predictive Cargo, Dart, PKGBUILD, manual-page, or changelog version bump.
• dev candidates are never published. After an exact validated merge,
  main independently builds the production candidate; a later signed tag
  versions and publishes those exact compiled payloads without rebuilding.

Fixed

• Managed X11 toplevels now always receive Denial's frame, rounded corners,
  and shadow, preventing decoration-free Xwayland windows from corrupting
  Impeller backdrop blur and shadow damage when minimized.
• Retained window-frame layers now include their shadow outset in partial
  repaint damage instead of clipping repair to the window's layout bounds.
• Denial now clears non-primary DRM planes inherited from the display manager
  before its first compositor frame, preventing a stale hardware cursor or
  overlay image from remaining latched above the Flutter desktop.
• Retained builder checkouts now run Flutter revision-transition hooks with
  the pinned depot_tools environment instead of depending on a host-global
  vpython3 command.
• DPMS wake now absorbs transient connector disconnects while monitors retrain
  their links, preserving Wayland outputs and client windows across display
  power cycles.
• Fully opaque client content no longer requests backdrop blur merely because
  its shadow, rounded corners, or antialiased border carries alpha.
• Complex Flutter damage regions no longer collapse touching L-shaped output
  repairs into a full-atlas repaint.
• Failed local tag-signing attempts now reliably erase the decrypted recovery
  kit and temporary keyring after function scope unwinds.
• Arch packages now disable host-default debug-package rewriting explicitly,
  keeping tag-promoted payloads independent of the build host.

The production binaries were built and independently checked from main on
Denial's owner-operated x86-64 runner. This signed tag promoted those exact
compiled payloads, assigned their package and runtime versions, and signed and
re-verified the repository in GitHub-hosted jobs. This release does not yet
claim an offline dependency closure, reproducible packages, independent
rebuilding, an SBOM, or AArch64 support.
