Changelog

v0.17

  • Don't kill whole server when a single process OOMs, thanks to @dragz - PR #101

v0.16

  • User variables (like {USERNAME}) are expanded in unit_extra_parameters, thanks to @tullis - PR #83
  • Some cleanup of packaging metadata, thanks to @minrk - PR #75

v0.15

Fixes vulnerability GHSA-cg54-gpgr-4rm6 affecting all previous releases.

  • Use EnvironmentFile to pass environment variables to units.

v0.14

  • define entrypoints for JupyterHub spawner configuration
  • Fixes for CentOS 7

v0.13

Bug Fixes

  • Fix slice support by making it a configurable option

v0.12

New Features

  • Allow setting which Systemd Slice users' services should belong to. This lets admins set policy for all JupyterHub users in one go. [Thanks to @mariusvniekerk]

Bug Fixes

  • Handle failed units that need reset. [thanks to @RohitK89]
  • Fix bug in cleaning up services from a previously running JupyterHub. [thanks to @minrk]

v0.11

New Features

  • Username templates let you map jupyterhub usernames to different system usernames. Extremely useful for prefixing usernames to prevent collisions.

Bug fixes

  • Users' home directories now properly read from pwd database, rather than assumed to be under /home. Thanks to @cpainterwakefield for reporting & suggested PR!

v0.10

Breaking changes

  • use_sudo option is no longer supported. It offered questionable security, and complicated the code unnecessarily. If 'securely run as normal user with sudo' is a required feature, we can re-implement it securely later.
  • If a path in readonly_paths does not exist, spawning user will now fail.

New features

  • Dynamic users support, creating users as required with their own persistent homes with systemd's dynamic users feature. Useful for using with tmpnb.
  • Add additional properties to the user's systemd unit with unit_extra_properties. Thanks to @kfix for most of the work!

Bug fixes

  • If a user's notebook server service is already running, kill it before attempting to start a new one. GitHub Issue

Dependency changes

  • Python 3.5 is the minimum supported Python version.
  • JupyterHub 0.9 is the minimum supported JupyterHub version.
  • Tornado 5.0 is the minimum supported Tornado version.
