Version 2.0 is about measuring honestly, and then measuring something new. FREQUENCY, NOT JUST AMPLITUDE - A dominant-frequency card on the Measure screen, in Hz, with a spectrum beside it - A full frequency spectrum screen with the three strongest lines listed - An optional rpm reading for 2 Hz to 50 Hz, phrased as a hypothesis about a rotating part - A clear "No clear frequency" state, because a flat spectrum is a real answer MEASUREMENT CHAIN REBUILT - Default sampling raised from 5 Hz to 100 Hz, with a 50 Hz option - Samples now carry the hardware sensor clock in microseconds instead of delivery time - Both processing filters are rate-independent now, at fixed 0.5 Hz and 2.0 Hz corners - Peak ground velocity is a real number: it was structurally always 0.00 before - Monitor now samples at 50 Hz instead of 5 Hz, so it reacts to events it used to miss SETTINGS THAT NOW DO SOMETHING - The AVG/RMS window setting reconfigures the real window, live, at 1, 5 or 10 seconds - The saved export profile is finally read and pre-selected in the export dialog - The sampling-mode subtitles are generated from the real target rate FIXES - Renaming a session, or editing its note or tags, no longer erases its felt intensity and PGV - One unreadable record can no longer wipe the whole session archive - A recording can no longer end as a zero-byte file - A second recording no longer appends to the first one's chart - The Start button stays reachable on small screens - The empty-chart hint no longer clips in 30 languages LANGUAGES - 54 locale codes across 43 languages, all hand-translated - Czech, which was translated but never delivered, now works - British English is no longer a copy of the US text - The recording status badge is translated instead of staying English Because the measurement chain changed, calibration values and the sampling-mode preference from 1.x are not carried forward. Re-run calibration once, it takes about 10 seconds.
