• Versions lower than v0.8.9.1 are no longer compatible as of date mentioned above

Available Downloads:

Windows (Windows 7 - Windows 11)
(other Windows versions might be supported but are not verified or tested)

• Espers-v0.8.9.1-p3-x1-Windows-qt: Contains a compiled binary executable with a user interface (Qt) for Windows OS
• Espers-v0.8.9.1-p3-x1-Windows-daemon: Contains a compiled binary executable with no user interface for Windows OS

Linux/Unix (Linux/Ubuntu 18.04 - 24.04)
(other Linux/Unix versions might be supported but are not verified or tested)

• Espers-v0.8.9.1-p3-x1-Ubuntu_XX.04-daemon: Contains a compiled binary with no user interface for Ubuntu XX.04 LTS
  (The "XX" characters when seeing "Ubuntu-XX.04" refers to Linux/Ubuntu OS version listed. For example "Ubuntu-18.04")

Any OS (User Compiled)

• Source code archives are provided for compiling for a specific OS that is not listed above

Notes:

Upcoming Linux/Ubuntu builds:

• In the future Linux static compiled binaries will be included. This means that users will not have to worry about specific versioning of the Linux OS (may still matter for large changes, such as 18.04-->24.04) and will also include pre-compiled Qt (GUI, user-interface) binaries as well. In the meantime you can compile either the "headless" (no user-interface) Espers daemon or the Qt (GUI, user-interface) Espers-Qt very easily by simply following the copy/paste guide available in the GitHub documentation (Go to the Espers repository page on github for more information and links directly to it)

Upcoming Apple Mac OS builds:

• This release, and all future releases, will be updated to include Apple Mac OS compatible pre-compiled binaries and build instructions on how to compile it if chosen to do so manually/on-your-own. In the meantime we are working diligently to provide these builds and instructions. It takes some considerable time and effort as it's created by the Espers Project Team working directly on an Apple Mac OS device to produce the new build for Mac OS and subsequent documentation with no available reference material to use as inspiration or shortcut.
