I believe in this update most of the items did not change except for stilts and the dryad's starting item. They both reveal a lot less for free (stilts to 5 from 8 and dryad to 5). Stilts costs 10 from 8. In general revealing 5+ should cost around 10 and revealing 4 will cost around 9.
The bow/sword were bumped to blue rarity from purple (rare I believe) and cost decreased to what most blue rare items are (6).
"Most dungeons have been altered to reduce heal items." should mean dungeons except the first level should have -1 or -2 pizza.
"Most dungeons have introduced Gold Slime." -Gold slime starts appearing from level 2 onwards. Similar to goldbug.
"Later dungeons have introduced Stone Watcher." -This mostly is meant to replace the 12/12 cyclops. Existing 12/12 cyclops have been replaced with an 8/8 version. Stone watcher brings back the 12/12 behavior for level 3 and onwards. Brick mimic I think is the same appearing around level 3 onwards.
