 App .NET MAUI Blazor Hybrid per Android, iOS, Mac Catalyst e Windows, pensata per consultare mappe catastali e lavorare sul campo con GPS.
 
+## Versione 0.4.10
+
+- I pannelli mobili rispettano la barra di navigazione Android e mantengono il pulsante Help completamente raggiungibile tramite scorrimento.
+
+## Versione 0.4.9
+
+- Linee e punti KML/KMZ vengono sempre importati, anche quando il documento viene riconosciuto come catastale; il filtro particelle separa soltanto i poligoni di foglio o cornice.
+
+## Versione 0.4.8
+
+- Aggiornamento a .NET 10 e target Android API 36.
+- KML e KMZ generici conservano punti, linee e poligoni; il filtro particelle viene applicato soltanto ai file riconosciuti come catastali.
+- Android propone LME tra le app disponibili per aprire KML, KMZ, GeoJSON, progetti JSON e backup ZIP.
+- I selettori file Android mostrano correttamente progetti condivisi e backup con estensione composta.
+
+## Versione 0.4.7
+
+- La ricerca nel pannello Layer conserva correttamente posizione e selezione del cursore durante il filtraggio; digitando `pio` il testo non viene piu invertito in `oip`.
+- L'elenco revisioni viene aggiornato dopo salvataggi manuali e automatici, rinomina, importazione e selezione del progetto.
+- Il pannello Progetti mostra quante revisioni sono disponibili e spiega quando un progetto appena creato non possiede ancora versioni precedenti.
+
 ## Versione 0.4.6
 
 - `Mostra cornice/layer del foglio` carica dal WFS ufficiale AdE il vero confine `CP:CadastralZoning` di ciascun foglio delle particelle.
