1.6 13/11/2022
"Menos es más", sometime less is more. This release get rid of the swipe keys. Many people ask for them as a bug or issue. It was a feature, may be a bad one.
1.5.1 Some corrections on zooming options, intended for non hardware button devices. Adjusting from 7% of freedom to 8.5% on framed and limited options. I need I realize and understand with my new iPhone mini. Now it looks great :D
Change the default zoom option to framed. Cool on iPhone mini too.
Many deprecated functions updated.
New default skin for HP48G without swipe for fast fingers users. You still can change the skin to use the swipe functions. If you already have a configured HP48 you should fetch from the "Skin Collection" the Don't Panic HD No Gloss, and then select the No Swipe skin on "Change Skin...".
1.5 Many people ask to have the option to disable the haptic feedback. Even when I dont feel as an adventage, there is the option to disable it.
The option to change the icon was removed as the new icon is cool enough.
So, on 1.5.x less is more.
1.5.1 16/11/2021
This version includes some minor bug corrections, and include the option to disable the haptic feedback. Don’t know why, but some people request it, so there it is.

1.5 06/10/2021
Just kill some bugs and last icon change.
1.4.6 22/07/2021
An invitation to a new icon and logo from a powerful force.
I like the older one but there are some kind of intellectual property rights infringement to trademark "Progress" logo that consists of 4 slanted parallel bars...
Anyway, this is a thumbnail of the running app, so it could be easier to understand...

1.2 17/02/2021
This version is slimmer than the previous one again. Don't forget to visit https://www.thinkchile.com/iHP48 and be kind ;)
I'm glad to share this to all the HP48 community and remember my university years.
The Copy Stack functionality was fixed. Not sure if it even works before...
Change label on those options to:
Copy from iHP Stack
Paste into iHP Stack
Update audio sessions deprecated Objective C code, and some other deprecations.
Enabling background audio... I got a performance request with the following context:
This feature is intended for use by apps that provide audible content to the user while in the background, such as music player or streaming audio apps.
So, the background audio is turning back off.
The Silent Mode switch, has been enabled.
Also, update the TheHP48 skin to a Don't Panic HD with no gloss... Could fix some resolution issues and improve the resolution of the skin.
Finally, the Files.app integration is on the road, so you can access iHP48 files from the iOS app, as it should be and not only from the "Filemanager..." inside of iHP48.
Some other lees visible... a lot actually.
1.1 12/02/2021
This version is slimmer than the previous one, the configuration settings have moved to the iOS Settings app, some non-used code striped, and added a sutil reminder to visit https://www.thinkchile.com/iHP48 and be kind ;)
A hundred of deprecated functions updated or just removed because provides marginal or cuestionable benefits.
I'm glad to share this to all the HP48 community and remember my university years.
