Lectern 0.8.0

Removed

• Cloud login, sync, and accounts. Lectern is now fully local — there's no sign-in, and
  nothing leaves your machine. Your provider logins (Claude Code, Antigravity, OpenCode) are
  unchanged, and encrypted session export/import still works.

---

Install (Linux)

• AppImage: chmod +x Lectern_0.8.0_amd64.AppImage && ./Lectern_0.8.0_amd64.AppImage
• .deb: sudo apt install ./Lectern_0.8.0_amd64.deb
• Terminal: curl -fsSL https://github.com/ShrimpScript/lectern/releases/latest/download/lectern-cli-linux-x64.tar.gz | tar xz

Installed Linux desktop apps update themselves from here. Windows/macOS installers follow via the cross-platform workflow.

Lectern 0.7.0

Added

• Checkpoints & rewind. Lectern snapshots your workspace before an agent writes to
  it, so you can undo a run you don't like and try a different prompt. Snapshots use a
  private, per-workspace git store that is completely separate from your project's own
  .git, so it works on non-git folders and never touches your history. Rewind reverts
  edits and removes files the agent added, and is itself reversible.
  • CLI: lectern checkpoint list and lectern rewind <id>.
  • Desktop: a checkpoint marker in the chat with an inline Restore action that also
    re-fills the composer so you can adjust the prompt and try again.
  • Secrets (.env) and the brain store are never snapshotted.
• In-app auto-updates (Linux). The desktop app checks for newer signed releases and
  offers a one-click Restart & update — download, install, relaunch. Every update is
  verified against Lectern's signing key before it installs.
• "What's new" on update. After updating, the app shows what changed in the new
  version, drawn straight from this changelog.

Lectern 0.6.0

Lectern 0.6.0 sharpens the brain, makes providers a click to set up, and documents how the whole thing works.

Smarter, leaner memory

Recall used to return the top-scoring files for any message, so a greeting in a broad workspace could surface unrelated files — noise that also risked sending the agent off to read them.

• Relevance floor — a file has to clear a similarity threshold to be recalled. Small talk now recalls nothing; genuine matches still surface.
• Snippets, not whole files — when memory content is actually needed, only the most relevant window of a file enters context. On a typical task that cuts recalled context by roughly 9×.
• The agentic path already passes recalled paths, not file contents, so the agent reads only what it needs. Memory no longer drains tokens.

One-click provider setup

Each provider in Settings (Claude Code, Antigravity, OpenCode, OpenRouter, Ollama) now expands an OS-aware setup panel: the exact install command for your platform, a Copy button, an auth next-step, and links to the full guide and the provider's official page. For the safe user-space installers (OpenCode, Ollama) there's a one-click Install that runs it and streams the output. The one-click path only runs vetted, hardcoded commands.

Documentation

New feature-level docs at getlectern.vercel.app/docs: chat commands and skill replay, the Conductor and how model routing works, the brain and recall, scheduling, and creating/importing/sharing Hub skills.

Fixes

• schedule cancel accepts the short id that schedule list prints, and reports a real miss instead of silently succeeding.
• Recall no longer indexes graphify's own cache into results.

Install

• Linux — Lectern_0.6.0_amd64.AppImage (chmod +x then run) or Lectern_0.6.0_amd64.deb.
• macOS — Lectern_0.6.0_aarch64.dmg (unsigned; right-click → Open the first time).
• Windows — Lectern_0.6.0_x64-setup.exe (unsigned; SmartScreen → More info → Run anyway).
• CLI + daemon — lectern-cli-linux-x64.tar.gz (lectern, lecternd).

Lectern 0.5.0

Lectern 0.5.0

First public release.

Terminal (CLI + TUI + daemon) — one command:

curl -fsSL https://github.com/ShrimpScript/lectern/releases/download/v0.5.0/lectern-cli-linux-x64.tar.gz | tar xz && sh install.sh

Nix

nix profile install github:ShrimpScript/lectern

Desktop app — download an installer below:

• Linux · AppImage — browsers strip the execute permission from downloads, so make it executable once, then run it:

  chmod +x Lectern_0.1.0_amd64.AppImage && ./Lectern_0.1.0_amd64.AppImage
  

  (or right-click → Properties → Permissions → Allow executing file as program, then double-click)
• Linux · .deb — sudo apt install ./Lectern_0.1.0_amd64.deb (or open with your package installer)
• Windows: .exe — unsigned: More info → Run anyway
• macOS (Apple Silicon): .dmg — unsigned: right-click → Open

Verify a download against SHA256SUMS.txt: sha256sum -c SHA256SUMS.txt --ignore-missing

Then run lectern doctor.
