Shiny Server Pro Release History

Follow

1.5.2

  • Fix bug where network connectivity issues with LDAP servers could cause a crash. Also, eagerly close connection between LDAP client and server when no longer needed.

1.5.1

  • Improve robustness with unfriendly proxy configurations. This had regressed some time between 1.4.3 and 1.4.7.

1.5.0

  • Upgrade to Node.js v6.9.1, and upgrade all npm dependencies. While no distinct features or significant bug fixes result from this upgrade, catching up to the current Node.js release is critical for the long-term health of our codebase.
  • SSL/TLS connections now support forward secrecy.
  • Fix bug where R processes would not be cleaned up if an HTTP request was prematurely closed.
  • Fix bug introduced in 1.4.7 where user could be logged out spontaneously, especially in interactive Rmd documents that contain many embedded sub-apps.
  • Fix bug where low-level network errors communicating with LDAP servers could cause a crash.

1.4.7

  • Add auto-reconnect capabilities. Can be disabled via `reconnect false;` config option (replaces `disable_reconnect true;`).
  • Upgrade to Node.js v0.10.47 (security patches).
  • Fix bug where running the admin dashboard behind a reverse proxy would cause problems with "Kill Process" and "Kill Connection" buttons, requiring ugly proxy rules to workaround. These should no longer be required.
  • The bookmarkable state feature in Shiny v0.14 is now officially supported. Use the `bookmark_state_dir` directive to store bookmarked sessions in a specific location (default is /var/lib/shiny-server/bookmarks).

1.4.6

Bug fix release.

  • Fix a bug where a 404 response on some URLs could cause the server to exit with an unhandled exception.

1.4.5

Security release to fix minor issues raised in penetration test results.

  • Add `disable_login_autocomplete` directive that can be used to instruct browsers not to attempt to autocomplete on the login screen. Note that servers can only suggest this behavior to browsers (and in particular, Google Chrome chooses not to comply, as its developers argue that disabling autocomplete decreases security rather than increasing it).
  • Add opt-in clickjacking protection via `frame_options` directive. Login and /admin URLs now served with `X-Frame-Options: DENY` (the former can be opted out with an `auth_frame_options allow;` directive).
  • Fix open redirection on __login__. Previously, a URL created with malicious intent could cause you to go to an arbitrary URL after successful login. Now, it is only possible to be redirected to a path on Shiny Server.
  • Add Cross-Site Request Forgery (CSRF) protection to login and other POST operations.

1.4.4

  • Fix fatal EBADF error that could cause server crashes.
  • Updated PAM integration to resolve bug with asynchronous PAM modules like pam_ldap, pam_vas, and nss_ldap.
  • Upgrade to Node.js v0.10.46 (security patches).

1.4.3

  • Added proxied authentication mechanism via the `auth_proxy` option.
  • Upgrade to Node.js v0.10.45 (primarily for updated OpenSSL).

  • Improve disconnected UI by adding modal with description.
  • Capture killing of sessions and workers from admin dashboard in server log.
