Hello there!
You are correct. The Palmeria theme is one of the first themes we designed.
However, it hasn’t gained much popularity, which is why it hasn’t been updated in a long time.
We may consider releasing an update for this theme if we see an increase in its usage.
With the name Palmera the theme does not come up on google. If you rename it to Palmeria – Hotel, Booking, Bed and Breakfast it will be very popular for those who search for it (even on google) and you will see that it will be used by many more people.
For example, I had a hard time finding it and I discovered an excellent theme.
As for the update, new features are not needed, a minimal update would be enough, but it makes the banner disappear and does not make it seem like the theme is abandoned.
Thanks
