v0.2.1

Montagent v0.2.1

Font acquisition and licence evidence, render profiling, and static layer prefix caching.

Fonts & evidence:
- Explicit font acquisition via URL or Google Fonts: `montagent fonts acquire` (CLI)
  and `fonts_acquire` (MCP). Returns candidate paths and verified evidence receipts
  without mutating project files (ADR-0197).
- Discover host fonts and licence classifications via `fonts_list` (MCP) and
  `montagent fonts list` (CLI).
- Vendor verified fonts into the project behind the licence gate via `fonts_vendor`
  (MCP) and `montagent fonts vendor` (CLI).

Performance & profiling:
- Render profiling: CPU ms per element, type and effect breakdown via
  `montagent render --profile` and MCP `render` parameter `profile: true` (ADR-0194).
- Static layer prefix caching: caches byte-identical bottom layer prefixes across frames
  to accelerate preview and export rendering (ADR-0195).
- Video painter probe bounds: bounded probe frame selection for video painters (ADR-0196).
- Wall clock gap tracking in progress file JSON (ADR-0193).

v0.2.0

Montagent v0.2.0

A render can now be watched while it runs, and the audio and path work from
the last few months is in.

Renders report what they are doing
- `render --progress-file <path>` writes a JSON record about once a second
  (state, phase, pid, frames done and total, fps, ETA, timeline position).
  Each record is replaced atomically, so a reader never sees a torn file.
- A render names its phase: preparing, rendering, finishing.
- The ETA is marked as an estimate, and is null with a stated reason until a
  rate exists.
- stderr gets a line at least every ~5 s, including during pre-flight.
- MCP `render` takes the same progress file. See ADR-0192.

Audio
- Audio effects: EQ, dynamics (compressor and limiter), loudness
  normalisation, and a master stage with a loudness target and true-peak
  ceiling.
- Audio crossfades across a cut, and ducking written as ordinary volume
  keyframes by a skill script.

Video and layout
- Paths: a shape path mask, text on a path, stroke trim with a draw-on, dash
  patterns, and morphs between unlike shapes.
- Projection: swivel, tilt and perspective on every visual element.
- Preview reads shrunk images through one mip level (ADR-0186).

Platforms
- Windows CI pins a checksummed ffmpeg (ADR-0187).
- Intel macOS is still built and shipped, but its tests no longer run in CI
  (ADR-0188).

Install
- cargo install montagent
- or download the archive for your platform below and put `montagent` on PATH.
  Six targets: macOS, Linux and Windows, each for x86_64 and aarch64.
  Check it against SHA256SUMS.
- You also need ffmpeg 7.1 or newer, built with libx264, on PATH (ADR-0115).

macOS
The two macOS archives carry a binary signed with a Developer ID and notarized
by Apple, done by the release workflow (ADR-0139). Extract it and run it. If
the first run has to happen offline, clear the quarantine flag first:
    xattr -d com.apple.quarantine ./montagent

v0.1.2

Montagent v0.1.2

Montagent is now on crates.io, and every release is signed in CI.

Install
- cargo install montagent
- or download the archive for your platform below and put `montagent` on PATH.
  Six targets: macOS, Linux and Windows, each for x86_64 and aarch64.
  Check it against SHA256SUMS.
- You also need ffmpeg 7.1 or newer, built with libx264, on PATH (ADR-0115).

macOS
The two macOS archives carry a binary signed with a Developer ID and notarized
by Apple, now done by the release workflow itself (ADR-0139). Extract it and
run it: no `xattr` step, and an MCP client can start it directly. The first
run needs an internet connection; if it has to happen offline, clear the
quarantine flag first:
    xattr -d com.apple.quarantine ./montagent

v0.1.1

Montagent v0.1.1

macOS binaries are now signed and notarized. Otherwise this is v0.1.0.

macOS
The two macOS archives carry a binary signed with a Developer ID and notarized
by Apple (ADR-0138). Extract it and run it: no `xattr` step, and an MCP client
can start it directly. macOS checks the binary with Apple the first time it
runs, which needs an internet connection; if that first run has to happen
offline, clear the quarantine flag first:
    xattr -d com.apple.quarantine ./montagent

Install
- Download the archive for your platform below and put `montagent` on PATH.
  Six targets: macOS, Linux and Windows, each for x86_64 and aarch64.
  Check it against SHA256SUMS.
- You also need ffmpeg 7.1 or newer, built with libx264, on PATH (ADR-0115).

Not in this release
- crates.io: `cargo install montagent` doesn't work yet.

v0.1.0

Montagent v0.1.0

The first release. Montagent is a video editor whose project format is written
and edited by an AI agent: a single JSON file states what is on screen at every
moment, and Montagent validates it and renders it, deterministically. One binary
is both the CLI and an MCP server.

Install
- Download the archive for your platform below and put `montagent` on PATH.
  Six targets: macOS, Linux and Windows, each for x86_64 and aarch64.
  Check it against SHA256SUMS.
- You also need ffmpeg 7.1 or newer, built with libx264, on PATH (ADR-0115).
- Each archive carries LICENSE, THIRD-PARTY.md, and examples/hello-text, a
  first project you can render without an MCP client.

macOS: this release is unsigned
macOS quarantines the extracted binary and kills it silently. Before the
first run:
    xattr -d com.apple.quarantine ./montagent
Releases after v0.1.0 are signed and notarized (ADR-0138).

Not in this release
- crates.io: `cargo install montagent` doesn't work yet.
