The description of the "Result" menu option was updated in ver. 0.06 of Perfect Cherry Blossom.
The stats overview menu was added in ver. 0.09 of Perfect Cherry Blossom and the difficulties names were not shortened.
In ver. 0.10, the spacing between the columns was increased, "Normal" was shortened to "Norm" and "Lunatic" was shortened to "Luna".
In the full version if you didn't unlock Phantasm stage yet, the screen would look like in ver. 0.10, however once you unlocked Phantasm, a new column called "Phants" would appear.
The enemy patterns at the beginning of stage 1 from Perfect Cherry Blossom have been changed in ver. 0.10.
In prior versions, the first enemies would spawn from the left side of the screen. They were a group of 6 fairies (with hats) coming in pairs, followed by an identical group spawning from the right side of the screen. The second formation were 6 fairies (with hats) on each side, aligned diagonally, in a shape resembling a ^. Two waves of such fairies would spawn, the second also containing 3 hatless fairies.
From ver. 0.10 onwards, the first enemies spawn from the right side of the screen. Two groups of 6 fairies with hats coming in pairs are followed by two identical groups spawning from the left side of the screen. There is no ^ shaped formation, instead another 2 groups of 6 fairies in pairs come from each side before the hatless fairies start spawning.
Please note that there are a lot more changes between versions. You can find them at the #trial7 tag, which is still in progress as of writing this post.
The fullstop at the end of the second row from Letty's theme description was removed in ver. 0.10 of Perfect Cherry Blossom.
Different song titles of full version themes from Perfect Cherry Blossom ver. 0.10 musiccmt.txt
If you extract the game files you can find the title and description of the songs from the Music Room in a file called musiccmt.txt. This particular file contains in ver. 0.10 songs that belong to the full version. The additional songs were removed in musiccmt.txt. of ver. 0.11, but they were added back in ver. 1.00. However some titles have been changed.
The Prismriver Sisters' theme was previously called simply 幽霊楽団 ~ Ensemble. This was updated in the actual full version release to 幽霊楽団 ~ Phantom Ensemble.
Yuyuko Saigyouji’s final spellcard theme had the title in english as Border of Life instead of ボーダーオブライフ. The extra stage and phantasm stage themes, were both called 妖々跋扈 ~. While the extra stage theme had the ~ removed in the actual full version release, the phantasm stage song got Who done it! after the ~.
Additionally, the phantasm stage theme description ended with a comma, but it was changed to an ellipsis in the actual full version release.
