Hi, it would be convenient to collect in a single thread all the issues developers run into with CEP 8 – please read the latest documentation CEP-Resources/CEP 8.0 HTML Extension Cookbook.md at master · Adobe-CEP/CEP-Resources · GitHub and contribute here with your findings. Please prefix with the CC app code you're testing against, eg. [PS], [ID], [IL], etc. [PS] Google Chrome 62.0.3202.62 (macOS Sierra 10.12.6) can't connect the debug session. The page correctly loads, showing the usual textual link with the panel title, but clicking the link leads to a blank page. The Console shows: inspector.js:601 Uncaught Error: No setting registered: showAdvancedHeapSnapshotProperties at Common.Settings.moduleSetting (inspector.js:601) at Object.Common.moduleSetting (inspector.js:698) at Common.VersionController._updateVersionFrom3To4 (inspector.js:646) at Common.VersionController.updateVersion (inspector.js:640) at Main.Main._createSettings (inspector.js:8500) at Main.Main._gotPreferences (inspector.js:8496) at Host.InspectorFrontendHostStub.getPreferences (inspector.js:892) at Main.Main._loaded (inspector.js:8494) at windowLoaded (inspector.js:287) Workaround: use Google Chromium instead (see Download Chromium - The Chromium Projects ) [PS] Using Version="8.0" in the manifest.xml (both in the <ExtensionManifest> and <RequiredRuntime>) makes the panel disappear from the Extensions list in PS CC 2018. Shouldn’t that be in sync with the CEP latest version?? [PS] Setting the panel's window.location = "chrome://version"doesn't load in the Panel the Chrome Version page anymore – it used to work fine with CC 2017. [PS ] Panel Geometry bug: setting in the manifest.xml <Size>, <MinSize> and <MaxSize> with equal values doesn't produce a fixed size (unresizable) panel anymore, as it used to do with any other pre-2018 version. In order to make a fixed sized panel in 2018, set only the <Size> tag. That is to say: panel is fixed size in 2018 but not in CC, 2014, 2015, 2015.5, 2017 or the other way around. Moreover, a panel that is collapsed/reopened, has completely wrong width/height, and may hide relevant content. [PS] Bug with Panel Refresh (either via Command+R on Chromium Dev Tools, or "window.location.reload(true)" in the panel). You may run into problems with Node after the first refresh unless you have both --enable-nodejs and --mixed-context flags in your manifest.xml [ALL] Some videos that used to play well (e.g. from YouTube) in CEP7, won't play at all in CEP8. This is due to a WebM VP9 codec that Chromium doesn't support anymore (the codec License doesn't get along well with the Chromium License, so they dropped the support) No CEF Client, nor an updated version of the ZXPSignCmd command-line utility, yet. I'll keep adding items to this list – I'm currently updating my Photoshop HTML Panels Development course to CC 2018 and I'm still finding stuff. Please look at the official documentation for Node.js changes in CEP 8 – if your panel uses node, you'd better off reading that. Davide Message was edited by: Davide Barranca, October 21st
