+## Versione Pro 1.0.11 test

+- Il flag Fogli catastali mostra il WMS di tutti i fogli agli zoom panoramici e, in dettaglio, il confine ufficiale WFS del foglio corrente anche senza dati caricati.
+- Se il foglio corrente e gia presente in un progetto o in un'importazione, l'overlay di navigazione non ne crea un duplicato.
+- La toolbar superiore rispetta l'area occupata dalla barra di stato e dalle notifiche Android.
+
+## Versione Pro 1.0.10 test
+
+- Migliora la compatibilita del servizio catastale AdE sui dispositivi Android meno recenti con HTTP/1.1, tentativi automatici e una ricerca GPS piu tollerante.
+- I messaggi sulla mappa si chiudono automaticamente dopo un intervallo configurabile, predefinito a 3 secondi, e includono un pulsante di chiusura.
+- La barra GPS mantiene sempre disponibili i comandi Avvia/Ferma e Centra, impilati sugli schermi stretti, e puo essere ridotta.
+
+## Versione Pro 1.0.9 test
+
+- Corregge la lettura del catalogo dal wrapper asincrono .NET di Google Play Billing, usando la raccolta managed `ProductDetails` popolata dal binding.
+
+## Versione Pro 1.0.8 test
+
+- Google Play Billing accetta tutte le offerte idonee restituite per i piani `monthly` e `yearly`, preferendo il piano base quando disponibile.
+- In caso di catalogo vuoto o prodotto non caricato, il messaggio mostra una diagnostica specifica restituita da Google Play.
+
+## Versione Pro 1.0.7 test
+
+- I messaggi informativi su telefono vengono mostrati sopra i controlli zoom e possono occupare fino a tre righe senza sovrapporsi.
+- Durante il rilevamento GPS la mappa si ricentra automaticamente quando la nuova posizione esce dall'area visibile, mantenendo lo zoom corrente.
+
 ## Versione Pro 1.0.6 test
 
 - Il pannello Layer usa tutta la larghezza disponibile sui telefoni e le righe si adattano ai testi su piu linee senza sovrapporsi.
