"Save As" didn't show on History status

Please take a look on cap screen.

I open a tif file ,  save as psd ,  duplicate a layer ,  save as jpg ....  the panel  shown "Save"  , not  Save As ....  IT SHOULD BE SHOWN SAVE AS .

Next step,  I quit it,   PS  prompt  me if  need to save before quit.  That means  I didn't save this file , but the history panel show "Save"...  If  I want to see the history panel to recongize what I done before,  that will be in trouble.  The history told me I "SAVED"   

In previous version, it doesn't like that.   I  use   "Shift Control + S", Save As,   the history panel will shown "Save As"

I'm not seeing what you're seeing, Jeff. I just get a save. I tried what you did with a new doc, and also older docs, using save as to keep the same file type and to change the file type. All showed just save.

Here's what I see when I create new document, save as (save as a PSD)

According to history, it's basically a save, as once the file is saved using save as, it's a new file, but it still has all the old history, which you can return to. You can't go back in history to the original file. Once you do a save as, the original file remains in the last saved state prior to the save as.
