0.18.1 Released

Friday, August 25, 2017 | Posted in Release

Pony 0.18.1 contains a high priority bug fix in the ProcessMonitor package. We recommend upgrading as soon as possible. There are no breaking changes in this release.

Process monitor async write buffering

Before this release, it was easy to swamp an external process started by the ProcessMonitor with too many writes. Excessive writes would result in errors and lost data. 0.18.1 adds write buffering thereby avoiding lost data.

DragonFly BSD 4.8 support

Pony has been ported to support DragonFly BSD 4.8. Note, we do not have CI for DragonFly, so support is provided on a “best-effort” basis. That is, we won’t intentionally break support, but we also aren’t actively testing commits against DragonFly so some breakage can be expected.


  • Don’t print capabilities for type params when generating docs (PR #2184)


  • DragonFly BSD 4.8 support (PR #2183)
  • Process monitor async write buffering (PR #2186)
