1) Addition of the information "Wheel power", "Measurement time", and "Measurement distance" in the power results sheets, which will however only become operational in the next version 6.1
2) Addition of 2 warnings to the automated control system for power and acceleration measurements: GPS receiver working, GPS accuracy

1) Aesthetic improvements "Part 1":
- Complete revision of all textual screens (22)
- Changed the order of results types in results lists
2) Making PerfectPower compatible with the phone's dark mode

Major evolution of the V6 version compared to the V5 version:
1) Ultimate and final optimization of the precision of power and acceleration measurements
2) Power: Addition in the power results sheets of an explanatory text on the "Max speed correction" function ideal in the event of poor GPS reception or failure of this one (indeed, 95% of the measurement accuracy is made by the accelerometer)

Change in precision of pressure units: The hPa remains with a precision of 1 digit after the decimal point, but the in Hg and PSI go from 1 to 2 digits after the decimal point

1) Addition of a function of power results correction on the measurement end max speed (very useful in case of poor GPS reception)
2) Increased the maximum number of results per type (power, accelerations, runs flying start) and per car from 10 to 20
3) Replacement of the old function of automatic recovery of weather data (versions prior to 4.1) by a function of manual recovery of these data in real time and by geolocation on the reference weather site "The Weather Channel"

1) All adaptations to iOS 16 (09/2022) + iOS mini changed from 9 (09/2015) to 11 (09/2017)
2) Equalization of the graphic rendering of all screens both horizontally and vertically for ALL iPhones since the 5 (09/2012), the first iPhone to have a 9/16 screen
3) Ultimate optimization of power and acceleration measurements accuracy (based on the "Accelerometer + GPS" combination)
4) Removal of the function of automatic recovery of weather data
5) Various textual and graphic modifications + Update of all web links (FR/EN guides)

The detail of these five modifications is given on the site in the NEWS section: https://www.perfectpower.ch/index.php/en/news#C2

1) All adaptations to iOS 12
2) Stopping any animation during all page changes
3) Lightening & Optimizing the Car page
4) Creation of the Calculation of gear ratios page
5) Moving reprises settings from the Car page to the Setup page, with creation of a dedicated page

Version 4.0.3:
1) IMPORTANT: For all iPhone with iOS 11.2: All graphics (power and accelerations) and performances simulation are automatically and temporarily set to 0, for reasons explained at this link: www.perfectpower-cars.eu/#PPCI
2) Changing the home message accordingly

Version 4.0.1:
1) All adaptations to iOS 11
2) Minimum iOS version required: 9 (7 before) - iPhone "min" that can accommodates this OS: iPhone 4S
3) A single mode of power measurement for user simplification (the GPS correction mode becomes this single mode: deletion of the Normal mode -obsolete because on the only basis of the accelerometer- and Rev correction mode -which will be replaced in the next 4.1 version by a "Maximum speed correction" available in the results sheet-)
4) A single mode of acceleration measurement for user simplification (the GPS correction mode becomes this single mode: deletion of the Normal mode -obsolete because on the only basis of the accelerometer-)
5) Optimization of the following two points:
- Calculation of losses (losses "under load" -losses proportional to the transmitted torque, "alpha C" type- and "passive" losses -losses independent of the transmitted torque, "a + bV^2" type-) for power measurements
- End of curve processing for power measurements
6) Optimization of the GPS correction law of the accelerometer informations for even more precise and regular results, and it is now adapted to all frequencies of GPS receivers (from 1 Hz to 20 Hz or +)
7) Deletion of the general calibration procedure that has become obsolete.
8) Specific calibration time for power and acceleration measurements reduced from 2 s to 1 s
9) Elimination of the taking into account of the pitch (rearing of the car with the acceleration) in the calculations of the power and acceleration measurements in the old Normal mode.
10) Modification of the technic of stopping power and acceleration measurements: if it is still done after 3 seconds of freewheel deceleration, it is now based on GPS informations and no longer accelerometer (gain of "stability", the GPS being insensitive to the parasitic effects of slope and quality of the road)
11) Optimization of the measurement control system
12) Removing the 10 pre-installed cars to leave only one, the default car: Aston Martin DBS
13) Optimization of the following displays:
- graphics (power, acceleration) for all types of screens (iPhone 4S, 5 / 5S / 5C, 6 / 6S, SE, 7, 8, 6 + / 6S +, 7+, 8+, X), now perfectly readable and well centered
- texts vertically (mostly "sliding" texts) for all types of screens (iPhone 4S, 5 / 5S / 5C, 6 / 6S, SE, 7, 8, 6 + / 6S +, 7+, 8+, X)
- texts horizontally for most types of screens (iPhone 4S, 5 / 5S / 5C, 6 / 6S, SE, 7)
Note: Text optimization horizontally on the screens of iPhone 6 + / 6S + / 7 + / 8 / 8 + / X is relatively long, it will only be performed in the next 4.1 version, this version 4.0 had to be released as quickly as possible , thank you for your understanding.
14) Track function fully reviewed
15) Automatic weather data recovery fully reviewed to adapt to the new Internet management methods of iOS> = 9
16) Minor retouching:
- Changing the home message
- Graphic retouching of the different screens
17) Cleaning the program, to remove anything that is not absolutely essential
