Release notes

1.0.1 — Langrenus

The current release, and in practice the first one you can use.

macOS builds can be opened at all. 1.0.0's macOS builds shipped with an invalid code signature: the build wrote the third-party licence notices into the app bundle after it had been sealed, which broke the seal. macOS refused those builds outright with "LunarAtlas is damaged and can't be opened" — not the ordinary unsigned-app warning, and no Open Anyway could get past it. The bundle is now sealed again once everything is in place, and the build verifies the seal, so this cannot ship unnoticed again.

Windows and Linux were unaffected by that. Alongside it:

• the Windows installer carries its own version and publisher metadata, so it no longer shows up with no publisher at all in its file properties;
• the build can be Authenticode-signed as soon as a certificate exists, timestamped and verified;
• the manual gained this wiki, and the release page now explains how to get past the first-start warning on both macOS and Windows.

1.0.0 has been withdrawn. Its downloads are gone, because its macOS builds could not be started. Everything below describes what 1.0.1 is, since 1.0.0 never really ran.

1.0.0 — Langrenus (withdrawn)

The first release. LunarAtlas puts IAU feature names on your own photos of the Moon, and it is an app now: there is nothing to install besides the app itself, and no terminal is needed at any point.

What it does

• Positions your photo by itself. Full disks, any phase, mosaics, and close-ups that show no edge of the Moon at all. It works out the position, orientation, mirroring and libration without being told.
• Names what it sees, from the IAU gazetteer: 9087 features — maria, craters, lettered satellite craters, mountains, rilles, ridges — plus landing sites.
• Refuses what it cannot trust. A quality check measures the photo first and explains, in plain language, what is wrong; Name it anyway overrides it and the photo keeps the warning.
• A viewer and editor in the browser, or in its own window: search, measure in km along the surface, draw, move names, hide names, restyle them.
• Exports at 1:1 or smaller — never upscaled — as 16-bit TIFF, 16-bit PNG or JPEG, with the names, your drawings, the grid and an info block drawn in.
• Your edits are kept in a sidecar beside the photo, and are used again by command-line exports.
• A command line for whole folders at once, scripted exports, and feature positions as JSON or CSV.

Accuracy

On a 200-megapixel mosaic: 621 terrain matches at 1.56 px RMS — 0.43 km. Across 590+ test files, no confidently-wrong result was seen. See How it works.

Platforms

macOS	Windows	Linux
.dmg, Apple silicon and Intel	installer .exe, per user, no admin rights	.tar.gz, with an optional menu entry

Developed and measured on macOS (Apple silicon). Windows and Linux are built and tested on every change but have had less real-world use — reports welcome.

Known limits

Steeply oblique views of the limb, very thin crescents without a timestamp, and mare outlines. All described honestly in Limits.

About version numbers

Releases are tagged v1.2.3. A tag may carry a crater name after the version — v1.0.1-Langrenus — and it builds version 1.0.1, titled LunarAtlas 1.0.1 – Langrenus. The name is decoration; the version is what counts, and it is the number that goes into the app, since macOS and Windows want one.
