New Content:
You now get to pick your wife’s name. Hitting enter without putting in a name for either your own name or your wife’s will result in a name being selected for you.

Added location, Pool. Scenes for Mia, Olivia, and Chloe there.
Added renders for hugs in most locations. Added renders for flirting in some locations.
Added scenes for Mia at the Club, in the Cafe, at the Beach, and at Home. Mia now has content comparable to that of Olivia and Chloe.
Some existing scenes got an extra render or two to help them flow better.
Added one scene with Hildy, and there are some extra renders for her available if you get all three girls, as well. New events may cause new dialog in the nightly conversation.

Added renders to the opening scene.
UI Improvements:
There are now graphical buttons to move you to the other locations, and you can easily see which girls are at those locations as their pictures are displayed on top of the location button. Locations have a red border if moving would advance time, and a blue border if it would not.

Text Buttons have been replaced with more attractive buttons, which change color when the mouse hovers over them.
Moving buttons are now in the same place on both the location screen and the character interaction screen.
All interactions with the girls are now in one place on the upper right of the character interaction screen, rather than split between left and right.
Added a help function, which gives a brief tutorial.
The game now has its own icon.
Functionality Changes:
Girls will sometimes be at the pool when they would have spent time at the club. Many of the girls will take an afternoon off of work at some point late in the game, as well, and spend the time at the pool.

Game Length has been changed from 20 days, to 21 days, so that the game now ends on the Sunday before you go back to work. I expect this number to get longer with later releases, although not *every* release will see an increase in game length.

Having a longer conversation with Mia at the cafe bar no longer causes you to use up your chance to flirt.
It is no longer possible to both flirt, or “get to know a girl better” and do a physical action like hugging or kissing on a single turn.
The options to ask for a recommendation or get a phone number now are available only after you take your action with the same girl, so while they don’t take an action themselves, they do require spending time with a girl to do.
