Release Notes for P4EXP, the Helix Plugin for File Explorer Version 2023.1 Introduction This document lists all user-visible changes to P4EXP that were made between releases 2003.2 and this release. To display the version of P4EXP that you are using, choose "Connection Information..." command from the More menu. P4EXP 2021.2 is compatible with the 2018.1 server release and above. P4EXP requires that P4V 2019.2/1883366 is installed. To enable file state icons in File explorer after install a restart of the explorer application is required. This can be done via the Windows Task Manager or by rebooting the system. -------------------------------------------------------------------------- Supported Platforms * Windows 7, 10 (x86, x86_64) Third Party Software P4EXP uses OpenSSL and SharpShell. License information is at the end of these release notes. The P4EXP installer uses WixWPFWizardBA. License information is at the end of these release notes. Known Issues Due to a limit on the number of file overlay icons allowed by Windows, the P4EXP icons may not show at all if other extensions using file overlay icons are installed. For more information and a workaround, please see: https://community.perforce.com/s/article/2771 On High-DPI display, bitmap buttons on installer final dialog are too small. This is a Windows problem that currently doesn't have a fix or workaround. -------------------------------------------------------------------------- New Functionality in 2023.1 Patch 1 (2023.1/2572384) (2024/03/14) (Job #119187) * Rebuilt with the latest p4api.net API to address possible vulnerability: CVE-2023-5759. -------------------------------------------------------------------------- New functionality in 2023.1 (2023.1/2456196) (2023/06/20) (Job #116071) * Rebuilt with the latest p4api.net API.
