Hi @wopsononock, there is one more thing that should be addressed, I think:

• templates/blockAuthors.tpl calls $author->getLocalizedAffiliation(), which OJS 3.5 removed from Identity and author's affiliations are now handled differently. No __call fallback, so it's a hard "Call to undefined method" error whenever the "Inline HTML Galley Sidebar: Authors" block is placed in the sidebar.
  displayInline.tpl already has the correct 3.5 form.

And maybe, nice to have:

• README still says "Requirements: OJS 3.4.x" — this release targets 3.5.
• getSupportedContexts() returning BLOCK_CONTEXT_SIDEBAR seems to be dead code in 3.5.
• HOOK_SEQUENCE_LATE / HOOK_SEQUENCE_CORE work only via the deprecated PKP_STRICT_MODE; Hook::SEQUENCE_LATE / Hook::SEQUENCE_CORE are current.

Thanks!
