Editora 0.9.1: the first release

July 6, 2026 · Adrian De Leon · release

Editora has its first tagged release: 0.9.1, with native installers for macOS, Windows, and Linux. This post is a tour of what’s in it, and a short story about the version number.

What Editora is

Editora is a fast, keyboard-driven programmer’s text editor, cross-platform and open source under the MIT License. The organizing idea is that every action is a registered command: the same command powers the palette (M-x), a keybinding, and any toolbar button, so nothing is buried in a menu you can’t reach from the keyboard. You pick the keymap that fits your hands, Emacs, CUA, Sublime Text, VS Code, or IntelliJ, and switch it live.

What’s in 0.9.1

Because this is the first release, it carries everything built so far. A few of the areas:

• Editing: multiple cursors and column selection, smart auto-indent, auto-close brackets, comment toggling, the full set of Emacs editing and movement commands, string manipulation, and finer-grained undo with an Undo History timeline.
• Code intelligence: TextMate syntax highlighting for 20-plus languages, language servers (with one-click install for all 21), autocomplete, and a Structure outline.
• Run and debug: run a file from a gutter play button, a Debug Adapter Protocol debugger for Java, Python, and JavaScript, and an HTTP client for .http files.
• Version control: native Git, a side-by-side and unified diff viewer, a merge resolver, and IntelliJ-style local file history.
• Docs and data: a native Markdown preview with Mermaid diagrams and LaTeX math, export to PDF, HTML, Word, and ODF, a server log viewer, and first-class CSV and TSV tooling.
• Workspace: projects and multi-window, bookmarks, personal notes, remote editing over SFTP, and a TODO tool window.

The full list lives on the What’s New page, and each feature has its own page linked from the home grid and the docs.

New this release: AI, on your terms

0.9.1 also introduces optional AI assistance, off by default. There are one-shot actions, explain a selection, rewrite it to an instruction, generate a commit message from the staged diff, and an inline ghost completion, plus a full embedded coding agent over the Agent Client Protocol whose edits land as undoable buffer changes you review and save. You can point it at the Anthropic API or at a local OpenAI-compatible model like LM Studio or Ollama, so it works without sending anything to a cloud if you’d rather it didn’t. The AI guide has the details.

Why 0.9.1 and not 0.9.0

The honest version: v0.9.0 was cut first, but a JReleaser misconfiguration published the GitHub release as immutable before the installer uploads finished. GitHub permanently reserves a tag once it has backed an immutable release, even after you delete the release and the tag, so v0.9.0 can never be reused on the repository. The fix shipped as 0.9.1, along with a few related release-engineering repairs: jpackage rejects a macOS --app-version whose first number is zero, so a 0.x.y build needed a placeholder version that gets rewritten back to the true one before the DMG is wrapped; and JReleaser needed to be told the default branch is master, not main, and to create the release as a draft before uploading assets.

None of that changes the app. It’s the kind of thing you only hit the first time you ship.

Get it

Download an installer from the releases page. They’re unsigned for now, so macOS wants a right-click → Open and Windows wants “More info → Run anyway” the first time. Signing and notarization are on the list.

Editora is built in the open, and with the help of AI coding tools. Issues and discussion are on GitHub.
