Hydra 0.2.13

Hydra 0.2.13 is a focused macOS terminal-presentation fix release.

Install

macOS

brew install --cask hydraterm/hydra/hydraterms

Linux

Download the amd64 or arm64 .deb below, or use the matching tarball. Building from source is documented in DEVELOPMENT.md.

What changed

• Fixed a macOS presentation defect where newly typed commands or terminal output could remain visually stale until a later scroll or window event.
• Updated the renderer to WGPU 23 and its matching Glyphon text stack, which uses the corrected macOS Metal sublayer presentation path.
• Preserved the PTY daemon, session-revival, Remote lifecycle, and SQLite concurrency protections from 0.2.12.

The attached binaries are the exact signed stable artifacts built from canonical product source ed242b8fe592193940e537a565dbd5fabb773a58. The reviewed public local-source representation is published in this repository.

Hydra 0.2.12

Hydra 0.2.12 matches the stable desktop build distributed at hydraterms.com.

Install

macOS

brew install --cask hydraterm/hydra/hydraterms

Linux

curl -fsSL https://hydraterms.com/install.sh | sh

Or download a package below. Building from source is documented in DEVELOPMENT.md.

What's in this build

• Hardened passkey-backed Remote enrollment and lifecycle verification.
• Fixed macOS launchd transitional-state races during Remote startup.
• Preserved SQLite WAL locks across concurrent app and Remote-agent openers, preventing the shared-memory page-in crash seen during Remote use and scrolling.
• Added clearer local lifecycle-failure messages while keeping private error details redacted.
• Updated audited Rust dependency locks.
• A PTY daemon that owns your terminal sessions, so closing the app does not kill a running agent.
• Native macOS universal and Linux amd64/arm64 desktop packages.

The attached binaries are the exact signed stable artifacts built from canonical product source 685400da2b0b6ba238dde15ae3be11762152fe32. This repository contains the reviewed public local-only source representation.

Hydra 0.2.9

Hydra 0.2.9 matches the stable desktop build distributed at hydraterms.com.

Install

macOS

brew install --cask hydraterm/hydra/hydraterms

Linux

curl -fsSL https://hydraterms.com/install.sh | sh

Or download a package below. Building from source is documented in DEVELOPMENT.md.

What's in this build

• Project deletion now closes every owned daemon session before removing its records, including live sessions that no longer have a tab, preventing orphaned PTYs.
• Recovered sessions are visible in the dashboard with explicit restore and release actions.
• A PTY daemon that owns your terminal sessions, so closing the app doesn't kill a running agent.
• Provider-history discovery: agent sessions already on your machine — Claude Code, Codex, Copilot, Cursor and others — appear in the dashboard, ready to resume.
• Projects, windows, split panes and layouts, with stash and revive for panes you want out of the way but still running.
• Agent-aware panes with blocked / working / done attention signals.
• A native GPU-rendered UI on macOS (Apple Silicon and Intel) and Linux (x86-64 and arm64).
• Secret-aware redaction: launch arguments that look like credentials are never persisted verbatim.

Community and source builds are network-silent by default. The update check and model-catalog feeds are behind the off-by-default official-distribution feature.
