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

9) Retouches de certains textes FR/EN
10) Re-targetage de PerfectPower 2.2 pour iOS 5.1 (iOS >= 5.1 requis)

1) Detection 100% automatique du démarrage, avec une précision améliorée approchant le centième de seconde, et permettant la suppression du paramètre "Trigger" (ce paramètre est encore présent mais est inopérant, il sera définitivement supprimé dans la prochaine mise à jour)

2) Prise en charge de l'iOS 6

3) Prise en charge de l'écran de l'iPhone 5 (non encore testé)

4) Images de calibration revues, et adaptées pour tous les iPhone (3GS, 4, 4S, 5) et iPod (3, 4, 5) (non encore testé sur iPhone 5)

5) Légères modifications de l'échelle graphique

1) Ajout d'un mode de correction pour les mesures d'accélération basé sur le gyroscope et le GPS

2) Ajout d'un mode de correction pour les mesures de puissance basé sur le gyroscope et le régime moteur

Ces deux modes permettent:
- le calcul automatique et permanent du pitch, fourni comme un résultat de mesure
- la suppression de l'obligation de son paramétrage, bien que le pitch soit évidemment encore nécessaire pour les mesures dans l'ancien mode
- Une dépendance à la qualité de la fixation du téléphone nettement diminuée: légers jeux de téléphone tolérés (supports pare-brise acceptés), tous niveaux de vibrations tolérés, légers désalignements tolérés
- Une dépendance au profil et à l'Ètat de la route nettement diminuée (attention cependant: cela modifie toujours les performances de la voiture, mais affecte beaucoup moins la précision intrinsèque de la mesure)

3) Remplacement de l'ancien mode de reprises basé sur les accéléromètres, par un nouveau mode basé sur le GPS. On y perd certes légèrement en précision, mais on y gagne en manœuvrabilité et en facilité d'utilisation, ce nouveau mode permettant des reprises en départ lancé et jusqu'aux vitesses les plus élevées

4) Amélioration du filtrage des grandeurs mesurées dans les modes accélération et puissance, permettant:
- Une amélioration de la précision des résultats (accélérations, puissance) et des courbes (accélération, vitesse, puissance, couple)
- Une plus grande tolérance aux mesures de puissance faites avec des supports pare-brise (provoquant des mouvements de téléphone néfastes à la fiabilité des résultats et générateurs de monstrueuses vibrations), et/ou sur mauvaises routes, et aux vitesses "élevées" des mesures en 3ème

5) Récupération automatique des données météo dans le monde entier avec correction altimétrique (QNH --> QFE), et délivrance d'un bulletin de localisation (coordonées GPS, altitude, nom de la station météo où les infos sont récupérées)

6) Révision intégrale de la gestion du contrôle des mesures, avec notamment l'ajout d'informations pour les nouveaux modes, la suppression d'anciennes informations inutiles, et la suppression du bloquage de mesure en cas de vibrations excessives (puisque celles-ci ne sont plus un obstacle aux mesures), maintenant passées en "warning"

7) Amélioration de la loi d'adhérence du simulateur de performances, plus adaptée aux pneus récents et développée plus empiriquement par des tests de motricité sur différentes voitures

8) Légère modification de la gamme des trigger (de 0,1 --> 2,0 m/s2 à 0,5 --> 2,0 m/s2)

9) Baisse de la durée maxi d'attente mesure de 15s à 10s

10) Remplacement de la condition d'arrêt de mesure sur la distance (à 1100m) par une condition d'arrêt sur 5 secondes de décélération consécutives; les deux autres conditions d'arrêt restent (freinage violent et 60s de mesure)

11) Modifications et retouches esthétiques de l'écran Test (notamment ajout d'un chronomètre, d'un compteur de vitesse GPS, d'un indicateur de distance, et d'un indicateur de précision horizontale du GPS)

12) Modifications des fiches Voitures (ajout d'un champ et de textes informatifs) et des fiches Résultats (ajout du nom de la voiture à qui appartient le résultat)

13) Modification de la procédure de calibration désormais continue, avec ajout de nouvelles images afin de mieux illustrer les différentes étapes

14) Retouches mineures et diverses (textes, ajout d'images et suppression d'autres, échelle des graphiques, couleurs, etc)
