nova

• Fresh installs work again. The tree-sitter-cylc repository was deleted from GitHub, so Nix failed fetching that Helix grammar; Nova Helix now bundles its exact source.
• The Alt Shift A animation popup no longer shows Accelerando, whose glyphs need a font Nova does not ship. It now excludes it from random picks and arrow browsing, as the welcome and yzx anima already did.
• Zellij runs without carried patches at upstream 77debdeb. Its theme picker includes classic, default, and default-light; Nova's inherited dark and light themes remain ansi and gruvbox-light.
• Ctrl q opens Zellij's close confirmation: Detach keeps the session running, Quit ends it for every client, and Cancel returns to the workspace.

Nova 2.1.0 source and notice review assets

Revision: 2b8f49524e8a63ea990921333dc3979b194098e5. Tag: nova-v2.1.0. The annotated tag records the maintainer's approval in RELEASE-APPROVAL.json.

The runtime archive is unchanged. The associated component source kit preserves full selected source/vendor trees, original notices, patches and Nix/Nova recipes. Its SOURCE-MANIFEST.json maps component derivations to those materials and hashes their files. Original notices inside source archives remain inside those archives; the language-runtime packet supplements them. License declarations retain their original scopes; this kit grants no replacement license.

Verify SHA256SUMS before extraction. Concatenate the following parts in this order; verify the reconstructed archive's size and SHA-256 against nova-release.json:

Build and replacement instructions

Build the recorded revision on x86_64 Linux with Nix (required for building, not running):

nix build 'git+https://github.com/Yazelix/nova?rev=2b8f49524e8a63ea990921333dc3979b194098e5#yazelix-no-rio-archive' --out-link rebuilt-archive

The pinned flake.lock selects build inputs; Nix may fetch those inputs and toolchains. The extracted SOURCE-MANIFEST.json records the Nova recipe root in build_graph[archive_derivation].env.novaSourceRoot; that root is under sources/. Component materials, original patches and complete vendor trees are mapped by components[].materials. The recorded graph retains build flags and recipes. To modify the build, edit a private copy of the selected source and its Nix recipe.

For a dynamic-library replacement test, use a private runtime copy. Match the library's lib/native provider with share/yazelix/archive-origins.txt and the source manifest, build an ABI-compatible replacement and replace the library at the same relative path, retaining its SONAME and loader links. Exercise it through that copy's bin/yzx. Static or embedded changes require rebuilding their consuming program. These steps do not establish that every applicable replacement/relink obligation is satisfied.

Nova 2.0 is the first release you can install without Nix. On x86_64 Linux:

curl -LsSf https://nova.yazelix.com/install | sh

The installer checks every download against the release's checksums and prints how to start. Nix and Home Manager installs work as before.

New since 1.0

• Install: Nix-free install on x86_64 Linux, and full macOS support on Apple Silicon through Nix.
• Much faster (measured on Linux):
  • Switching tabs updates the top bar in about 45 ms instead of over 100 ms.
  • A new tab's top bar and Radar sidebar appear in about 0.2 s instead of 0.5 s.
  • Each Zellij mode change, such as entering pane mode, used to cost Radar and the top bar about 120 ms of CPU decoding the full keymap. It now costs under 2 ms.
  • A fresh terminal starts 14% faster.
  • Every tab shares one Radar, so opening more tabs does not multiply its work.
• Upstreamed to Zellij: Nova no longer needs its own Zellij fork. Zellij's maintainer merged the fork's changes into Zellij itself, most of them Lucca's fixes (#5630). Nova now runs upstream Zellij with two small patches, and every Zellij user gets:
  • Sixel and Kitty image fixes, and stacked panes that keep their order.
  • Swap layouts applied by name, and double, heavy and dashed pane borders.
  • Lucca's follow-up fixes: #5631, #5687, which keeps pane order when a tiled layout is reapplied, and #5706, which delivers startup events to background plugins.
• Terminal: Nova Rio, a pinned Rio fork, replaces Mars.
• Radar sidebar: tabs, panes, and running agents and jobs at a glance. yzx radar-setup connects Codex.
• Workspace keys:
  • New tabs open in a zoxide search of your recent folders.
  • Alt Shift T and Alt Shift W create and close tabs.
  • Alt j and Alt k cycle through panes.
  • Ctrl Alt h/j/k/l move the focused pane.
  • The command menu's layout entry switches between stacked and split panes.
  • Alt Shift B hides or shows the bottom hints.
• Top bar: before, it showed at most six tabs, however wide the window. Now it shows every tab that fits. When tabs need more room, the widgets on the right hide one at a time and come back when space frees up. New quota widgets show your Codex and Claude usage limits.
• Anima: yzx anima adds Aquarium, Matrix, Physarum, Chladni, Friends and Enemies, and more.
• Tools: Ratconfig edits Rio settings, yzx doctor and yzx status gain JSON output, and every shell keeps Atuin history.

Since 1.5

• yzx doctor and the installer warn when another yzx comes first on PATH, and say how to put this one first.
• The installer prints a short summary: progress, then how to start, learn and get help. install.sh --help prints the provenance check.
• Helix's Alt r reveal no longer reports openedinvalid_payload.
• The command menu closes after an entry instead of holding at [EXIT CODE: 0].

The changelog lists every change since 1.0.

• Nova installs without Nix on x86_64 Linux. Each release publishes install.sh, which verifies the release archive's checksum, installs it under ~/.local/share/yazelix-nova and links yzx into ~/.local/bin without editing shell startup files. --version pins or rolls back a release; --uninstall removes it and keeps configuration and state. macOS continues to install through Nix.

• The release archive identifies itself as Stable: the bar badge of an installed archive reads STABLE instead of EDGE.

• Clicking a tab switches to it when the mouse button is released. After you leave a tab with a click and return with the keyboard, the first click there is no longer ignored.

• The welcome and yzx anima no longer show Accelerando, whose glyphs need a font Nova does not ship. It is left out of random picks and arrow browsing, and welcome.style = "accelerando" is rejected. Anima removed the logo and static card styles, so the welcome always plays an animation and yzx anima static reports an unsupported style. A config that still selects either style gets a random animation.

• Ctrl Alt h and Ctrl Alt l move the focused work pane into the left or right column of the split arrangement. The pane stays focused and the other panes keep their order. Moving out of the outermost column, in the stacked arrangement, or with a popup open does nothing. Tab movement moves to Ctrl Alt Shift H and Ctrl Alt Shift L.

• appearance.straight_border_style = "double" draws double pane borders again. Since Nova moved to upstream Zellij the setting was silently ignored; Nova now writes Zellij's own border_style setting. Double borders keep square corners even when rounded_corners is on.

• Quota widgets use Eon's text and backend. Each window reads like 3h/5h 74% · 6d4h/7d 42%: time into the window, its length and the remaining percentage. Token counts are gone. Codex and Claude quota come from CodexBar, as in Eon; Claude's quota read no longer waits on the Claude CLI and times out. Claude refreshes every five minutes and Codex every minute, as in Eon. OpenCode Go shows 5h, 7d and 30d windows. tu (tokenusage) is no longer included in Nova shells.

• Tab clicks use upstream Zellij's mouse handling again, without Nova's patch. After switching tabs with a mouse click and returning with the keyboard, the first click in that tab can be ignored; clicking again works.

• macOS on Apple Silicon is fully supported. Native CI builds every package and starts a real managed session before a shared change is accepted.

• Alt m and pane mode's n, d and r (Ctrl p then the key) open new panes at the tab's workspace root instead of the focused pane's directory, keeping their stacked, split or directional placement. A shell that has cd'd into a subdirectory no longer decides where the next pane starts. Pane mode's s still stacks in the focused pane's directory.

• The Claude quota widget shows the Claude splat in terracotta (#D97757) instead of a plain C, in dark and light appearance. It uses the packaged JetBrains Mono Nerd Font 3.5 face, so no font change is needed.
