- Upgrade Node.js to 16.14.0.
- Drop support for Ubuntu 16.04.
app_dirconfig directives pointing to missing or unreadable directories on disk were causing errors during routing, even for requests intended for unrelated apps.
- Fix an issue where entire R processes would leak if: 1) they ever called
reticulate::source_python(), and 2) were running at the time that Shiny Server stopped (or restarted). Both conditions were required to trigger the leak.
- Fix a bug that resulted in the log message "MaxListenersExceededWarning: Possible EventEmitter memory leak detected."
- Upgrade Node.js to 12.22.6.
- Major upgrade to SockJS client (from 0.3.4 to 1.5.0). Technically, this adds two new SockJS protocols,
htmlfile, but the vast majority of admins shouldn't need to think about this. (The new protocols will be used automatically if necessary, unless either they or the older SockJS protocols
iframe-htmlfileare disabled in shiny-server.conf using the
- Drop support for Ubuntu 14.04. The oldest supported Ubuntu version is now 16.04.
- Fix a security vulnerability that could allow the download of published application source code directly from the server.
- Fix an issue where a failure in a certain phase of R process launching would result in a broken process being treated as a normal process, and repeatedly used to (unsuccessfully) serve new clients.
- Upgrade Node.js to 12.20.0.
- Drop support for RedHat/CentOS 6.
- Fixed a bug where unreliable LDAP server could crash Shiny Server Pro.
- Fixed a bug where
utilization_schedulerwas not respecting load factor of exactly 0.
- Upgrade Node.js to 12.19.0.
- Support for Ubuntu 14.04 has been dropped, and support for Ubuntu 20.04 has been added. (Ubuntu 16.04 and 18.04 continue to be supported.)
- Added support for SameSite=None cookie attribute. Without this support, when Shiny apps are displayed within iframes and require authentication, newer browsers that implement the "Incrementally Better Cookies" IETF draft proposal (at the time of this writing, only Google Chrome 80, though Firefox and Edge also intend to) will not be able to login. See the "Displaying Shiny apps inside iframes" section of the Shiny Server Pro Admin Guide.
iframebased SockJS protocols were using a CDN copy of a JS library that no longer exists, causing breakage. Now an internal copy is used. (The
iframeSockJS protocols should not be needed for browsers that are supported by Shiny Server these days; if you ran into this problem, please revisit the value you're using for
disable_protocols, and especially try removing
xhr-pollingfrom the disabled list.)
- Upgrade Node.js to 12.18.0.
- Upgrade dependencies to latest versions.
- BREAKING CHANGE: By default, Shiny Server Pro now requires TLSv1.2 or higher when establishing TLS connections. This applies to serving HTTP using the built-in SSL support, and to connecting as an LDAP client to authentication servers. If you have web browsers or LDAP servers that do not support TLSv1.2+ you will need to upgrade them; or, if you must, you can use
ssl_min_versionto try to re-enable obsolete versions of TLS.
- Upgrade Node.js to 12.15.0.
- Upgrade dependencies to latest versions.
disable_protocolsdirective now has
pollingoptions for easily disabling families of protocols.
- Now able to redirect R logs to the main shiny-server process's stderr, which is useful for containerized deployments and other scenarios where log files on disk are inconvenient to access. Enable this functionality by setting the environment variable
SHINY_LOG_STDERRto a non-empty value.
auth_durationdirective now detects values less than 10 (minutes), and logs a warning that a value of 10 minutes will be used instead. This is to prevent seemingly-spontaneous logouts of active sessions, which only refresh their auth cookies every 5 minutes or so.
- Local app configuration files (.shiny_app.conf) now respect the
- Fixes benign XML parsing error message in Firefox JS console.
- Upgrade Node.js to 10.15.3.
- Upgrade lodash dependency (CVE-2019-10744).
- Support Red Hat 8 and SLES 15.
- Admin dashboard now works properly when accessed via a raw IPv6 address.
- Modify Google OAuth 2.0 implementation to stop using soon-to-be deprecated Google API endpoints. Some of these endpoints appeared to be causing login attempts to "hang" at the Google consent step.
base_urldirective, which should be used under
adminnodes when Shiny Server is being fronted by a reverse proxy like Nginx or Apache, to tell Shiny Server what URL the browser sees. This URL is used for forming absolute redirect URLs, such as those needed to support Google OAuth authentication.
- Fix bug with listening on port 443.
- Fix bug with listening on port 80.
- Upgrade to Node v8.11.3.
- Added support for listening on IPv6 addresses.
- X-Powered-By response header now reports "Shiny Server" instead of "Express".
- For LDAP double-bind authentication, use the
base_bindaccount to iterate the user's groups (rather than the user's own LDAP account, which sometimes does not have permissions to see its own groups).
- Resolve permissions issues when log directory is on an NFS mount with root squash. The
log_as_userdirective was intended to work for these situations, but would fail in common configurations. It should now work.
log_file_modeno longer respects the process umask, and the default has been changed from
- Exit code of shiny-server process was always 0, regardless of the reason the process exited. Now a non-zero exit code is used if the process was terminated by a signal, or an unhandled error crashed the process, or loading of the shiny-server.conf config file failed during startup.
auth_ignore_casedirective, which can be used to treat
required_groupdirectives as case-insensitive. Disabled by default, as it's only safe to use on systems that prevent the creation of users/groups whose names vary from existing users/groups only by case.
- For SSL/TLS configurations, remove support for TLSv1 by default (SSLv2 and v3
were already not supported). If a stricter or looser policy is desired, this can be achieved by adding
ssl_min_versionas a child directive of
ssl; valid values for
- Upgrade to Node v8.10.0.
- Dropped support for Ubuntu 12.04 and SLES 11.
- Rename CSRF token cookie from
SSP-CSRF, so as not to conflict with other Angular apps being served from the same host.
- Fix bug where dashboard could show incorrect or even negative values from RAM usage.
- Fix bugs retrieving LDAP/Active Directory groups when
group_filtercontains an extensible match operator (which is the default for
- Support gzip/deflate compression for HTTP responses. You can disable this if necessary with the directive
http_allow_compression no;at the top level of shiny-server.conf.
- Fix bug where server could crash with "render is not defined".
- Don't color log output if stdout is not a terminal.
secure_cookies always;directive, which adds the HTTP cookie flag
"secure"to our session cookies. Note that this should only be used if all authenticated apps and the admin dashboard are ONLY accessible via https, either through Shiny Server Pro's built-in TLS support or via a proxy.
- Dropped support for RedHat/CentOS 5.
- Added floating license support through the new
license_typeconfiguration directive. The floating licensing model makes it easier for multiple instances of Shiny Server to share a license, such as in cloud environments.
- Fix a rare crash that can occur when a logged out user has a second browser
tab open with an app that's trying to reconnect.
- Fix several bugs in
- Upgrade to Node.js v6.10.3.
- Upgrade to pandoc 126.96.36.199.
- Refactor scheduler code to make enforcement of connection limits more robust.
- Utilization scheduler behavior is more intuitive, especially around connection limits and load factor.
- Add `log_file_mode` directive; set this to 0644 to allow application log files to be globally readable.
- When using `auth_pam`, login can be slow if the user is part of many groups and/or those groups have many users. This release does not speed up the login process, but it does prevent slow logins from tying up other requests, by performing the group retrieval on a worker thread.
- Fix bug where LDAP returns no groups when username contains a backslash.
- Fix bug where using `frame_options` directive would cause a crash.
- Upgrade to Node.js v6.10.0
- 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.
- Improve robustness with unfriendly proxy configurations. This had regressed some time between 1.4.3 and 1.4.7.
- 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.
- 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).
Bug fix release.
- Fix a bug where a 404 response on some URLs could cause the server to exit with an unhandled exception.
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.
- 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.

- Added Google Authentication (OAuth2) as a new authentication strategy.
- Added support for custom page templates -- exposing the ability to customize the static pages generated by Shiny Server for directory listings or errors.
- Support PAM for auth (auth-pam) and session creation (pam-sessions-profile).
- Leverage bash when spawning Shiny processes on behalf of other users, as in 'user_apps' mode.
- Support custom locations for the R executable in the configuration file.
- Added the '' and '*' special-cases to the 'required_user' setting.
- Added the 'exec_supervisor' setting to allow administrators to prefix the R process with a command, such as 'nice'.
- Bug fix: Restored compatibility with IE8 Standards Mode
- Added a health check endpoint at /health-check (two underscores on either side) which makes various statistics about the server available.
- DEPRECATED: No longer offering a health-check endpoint '/ping'.

- Added scheduler and traffic direction which require shiny >= 0.6.0.99 to be compatible.
- Support for node-webkit-agent (https://github.com/c4milo/node-webkit-agent). Use by setting DEBUG_PORT environment variable to a port number, then follow the instructions on the node-webkit-agent GitHub page under "Connecting to the agent". (At the time of this writing, node-webkit-agent only supports Node v0.8.x, not v0.10.x.)
