+rcalc (0.1.28-1) unstable; urgency=medium
+
+  * Upstream 0.1.28 (version from Cargo.toml), first Debian packaging.
+  * Binary is built in an Ubuntu 22.04 container (glibc 2.35 baseline), so the
+    package installs on Ubuntu 22.04 / 24.04 / 26.04.
+  * Ships /usr/bin/rcalc, /usr/share/applications/rcalc.desktop, hicolor icons
+    taken from ico/, AppStream metainfo and postinst/postrm cache refresh hooks.
+  * Depends are generated from the ELF with dpkg-shlibdeps.
+  * Build fix: clippy::approx_constant error in the convert round-trip test
+    (3.1415927 -> std::f32::consts::PI).

+Description: desktop calculator with programmer, engineering and convert tools
+ Calculator inspired by the Windows Calculator (standard mode), written in
+ Rust with the Slint UI toolkit. Modes: Standard, Engineering, Programmer,
+ Convert, CRC and Settings.
+ .
+ Programmer mode shows HEX / DEC / OCT / BIN at once, with QWORD / DWORD /
+ DINT / WORD / INT / BYTE word sizes, bitwise operators and clickable bits.
+ .
+ Convert mode maps a float32 to two 16-bit PLC words in every byte order
+ (AB CD / CD AB / BA DC / DC BA), approximates electronic gear ratios as
+ num/den and converts Char / Hex / Dec ASCII codes.
+ .
+ CRC mode computes Modbus RTU CRC-16 and Modbus ASCII LRC from a string of
+ hex bytes, e.g. "01 03 00 00 00 0A".
