Release notes
Astraea 1.1.0
The interface now follows the same desk as Echoes, and the dark theme keeps its type on the night ink.
What changed
- Echoes desk. Iris and coral replace the teal pairing. An aurora sits behind frosted search and navigation (the view bar, the week strip, the desktop sidebar, and timezone search). Event cards use a gloss gradient, and opening an event paints that same gradient instead of a flat fill. The accent chosen in Settings still drives buttons and the current day.
- Dark theme contrast. The month title, the weekday names and the days from the neighbouring month use the full night ink, so they stay readable on the navy aurora. An event's description uses that same ink against the event colour. A bright event colour is deepened until the type stays light.
- Bitcoin orange by default. Navy and Nostr stay available in Settings. An accent already saved on the device is left as it is. A freshly placed Android widget starts on the same orange.
The full history is in CHANGELOG.md.
Android: pick your APK
This release ships split per ABI, so the download is roughly a third of the size of a universal build.
| Your device | File | Size |
|---|---|---|
| Virtually every phone from ~2017 on | astraea-1.1.0-arm64-v8a.apk |
24 MB |
| Older / low-end 32-bit ARM | astraea-1.1.0-armeabi-v7a.apk |
22 MB |
| Emulator, ChromeOS, x86 tablet | astraea-1.1.0-x86_64.apk |
26 MB |
If you're not sure, take arm64-v8a. Installing the wrong one fails cleanly at install time. Minimum Android 7.0 (API 24). The package name is unchanged, so this installs over 1.0.0.
