Syncplay 1.5.6 Beta #1

Posted by Etoh on July 22, 2018

Python 2 is being officially retired in 2020, and so it is important for Syncplay to begin the transition to Python 3. For Windows this currently means Python 3.4 (which still supports PySide1 and py2exe), but for other platforms we now support Python 3.4-3.7.

Note: Due to changes in how the Syncplay configuration file is saved you may have difficulty reverting from Syncplay 1.5.6+ back to Syncplay 1.5.4 or earlier. If you care about this then backup your syncplay.ini/.syncplay file prior to testing out Syncplay 1.5.6+. Going from 1.5.6+ to 1.5.5 should be fine.

P.S. The server guide has been updated by albertosottile to explain how to run a server on macOS:

Warning: There are two known bugs in this release: File sizes being reported as ‘???’ and erroneous ‘not ready’ messages. A second beta is in the works!

Syncplay 1.5.6 Changelog:

  • Transition to Python 3. Python 3.4+ is now required to run Syncplay. (Issue #169 by FSMaxB with input by albertosottile, xNinjaKittyx, and et0h) resolved by PR #191 (by albertosottile with support from xNinjaKittyx and et0h)
  • Code syntax refactoring (#192 by xNinjaKittyx with code review by albertosottile and et0h)

Note: This open source software has been marked as clean by Jotti (.exe, .zip, .dmg, legacy .dmg) and VirusTotal (.exe, .zip, .dmg, legacy .dmg). Syncplay might be flagged as suspicious by some anti-malware systems simply because it is niche software downloaded from the Internet but as we are open source anyone can audit our code if they wish to do so.
