The app is unchanged. This release was an attempt to make the build byte-for-byte reproducible, so that F-Droid could ship the APK published here instead of its own: the ART baseline profile and AAPT2's PNG recompression were switched off, both being sources of byte-level noise. The attempt failed — the toolchains still differ, and disabling PNG recompression made it worse while costing 53 kB. Version 1.5.4 reverts that part. Reproducibility is not claimed.
