[Q] CEP 7 to CEP 8 transition

Report · Oct 03, 2017

Hi all,

I'm going through CEP 8 beta document and not sure what to expect.

I'd like know what happened on CEP 6 to CEP 7 transition from someone experienced.

Would it be GM with CC 2018?

Would Photoshop CC 2018 work with old CEP 7 plugin?

Or it needs to migrate to CEP 8.

Would Photoshop CC 2017 work with new CEP 8 plugin?

Thank you,

Naoki

You can Install all PS versions from CC 2017, 2015.5, 2015, 2014 up to CS6 a check how it works in backward compatibility.

Most common thing is change supported PS version in manifest and add debug key in registry for new CEP version.

And older PS versions should have older Chromium version and older DevTool version.

Hi Naoki,

I try to test some extensions that made for CEP 7 and worked fine in CEP 8(some extensions using node.js).

However, I'm not shure if plugins previous version will work in new PS.

Hi all,

I think there is not good answer because Adobe seems not guarantee the compatibility.

But the CEP 8 code is already posted, so we can figure out.

Here's some finding from my research. (I did not know before posting question)

* CEP engine was installed with each Adobe application and it's version.

Version info: ex) C:\Program Files\Adobe\Adobe Illustrator CC 2017\Support Files\Contents\Windows\CEPHtmlEngine

VersionInfo.xml

As I checked it seems update for quarterly update on CC 2017.

* Code signing file may be changed by CEP version. (CEP 8 is not posted)

I think we cannot specify CEP version from minimum version only (maximum version seems not supported).

By this, I think it could be limitation as following.

a) ABC2017 plugin specify min version = 2017

CC App 2017 will load this.

CC App 2018 will load this.

b) ABC2018 plugin specify min version = 2018

CC App 2017 will not load this.

CC App 2018 will load this.

I think there is no way to support a) case to be loaded by only CC App 2017.

As CC apps are subscription base, it might be not issue though.

Thank you,

Naoki
