Understanding Reader Updates
As I understand, there are 3 "versions" of Acrobat Reader:
- Reader DC (cont. track, started in 2015),
- Reader 2015 (classic track)
- and Reader 2017 (classic track).
Tabbed UI was added in Reader DC (cont. track) version 15.009.20069, which was released Oct. 13 2015:
- ftp://ftp.adobe.com/pub/adobe/reader/win/AcrobatDC/1500920069/ - to download
- Release Notes | Adobe Acrobat, Reader - to check the date
However if I download Reader 2015 (classic track) and manually update it to version 15.009.20069 (this update was released at the same date - Oct. 13 2015) - I will not see tabbed UI:
- ftp://ftp.adobe.com/pub/adobe/reader/win/Acrobat2015/1500630033/ - to download Adobe Reader 2015 itself
- ftp://ftp.adobe.com/pub/adobe/reader/win/Acrobat2015/1500630094/ - to download update
- If you want to check the date - see the link above
Why?
Does it mean that despite updates for 2015 classic track and releases of cont. track were released at the same dates (Apr. 6 2015, then July 14 2015, then Oct. 13 2015 and so on), these updates gives different changes?
