shiny-server 1.5.23 (Unreleased)
--------------------------------------------------------------------------------
* Now works with macOS and with Linux ARM64, when built from source.
* The undocumented `--daemonize` argument to `shiny-server` has been removed.
* RedHat/CentOS 7 is EOL as of July 1, 2024, and is no longer supported.
Ubuntu 18.04 is EOL as of May 31, 2024, and is no longer supported.
* Upgrade to Node.js v18.20.4. We also moved back to using the official Node.js
binaries, as we no longer need to build our own for compatibility with the
older version of glibc used in RedHat/CentOS 7.
shiny-server 1.5.22
--------------------------------------------------------------------------------
* Implement support for Shiny Express syntax for Shiny for Python.
* When running Shiny for Python apps, stdout and stderr output are both saved to
the app log file; previously, only stderr was logged (and this is still the
case for Shiny for R apps).
shiny-server 1.5.21
--------------------------------------------------------------------------------
* Increase the maximum allowable WebSocket message size that can be sent from
the Shiny server to the browser, from 64MB to 512MB. (The maximum message size
allowed from the browser to the server remains 64MB.)
* Migrate google_analytics_id implementation from Universal Analytics to modern
gtag.js.
* Upgrade Node.js to 18.18.2. We also moved from using the official Node.js
binaries to building our own, for compatibility with the older version of
glibc used in RedHat/CentOS 7 (which the official binaries no longer support).
shiny-server 1.5.20
--------------------------------------------------------------------------------
* Support hosting of prerendered Quarto `server: shiny` interactive documents.
Prerender the document before uploading by running `quarto serve index.qmd`,
then deploy the generated index.html, index_files directory, and the source
index.qmd together to be served by Shiny Server.
* Upgrade Node.js to 16.18.1.
shiny-server 1.5.19
--------------------------------------------------------------------------------
* Support hosting of Shiny for Python apps. For more information, see:
https://shiny.rstudio.com/py/docs/deploy.html
shiny-server 1.5.18
--------------------------------------------------------------------------------
* Upgrade Node.js to 16.14.0.
shiny-server 1.5.17
--------------------------------------------------------------------------------
* `app_dir` config 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.
* 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, `eventsource` and `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-eventsource` and `iframe-htmlfile` are disabled in shiny-server.conf
using the `disable_protocols` directive.)
shiny-server 1.5.16
--------------------------------------------------------------------------------
* SECURITY: Fix a serious vulnerability where maliciously formed URLs can result
in source code disclosure. Please upgrade as soon as possible!
* 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.
shiny-server 1.5.15
--------------------------------------------------------------------------------
* Upgrade Node.js to 12.19.0.
shiny-server 1.5.14
--------------------------------------------------------------------------------
* `iframe` based SockJS protocols were using a CDN copy of a JS library that no
longer exists, causing breakage. Now an internal copy is used. (The `iframe`
SockJS 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-polling` from the disabled list.)
* Upgrade Node.js to 12.18.0.
* Upgrade dependencies to latest versions.
shiny-server 1.5.13
--------------------------------------------------------------------------------
* Upgrade Node.js to 12.15.0.
* Upgrade dependencies to latest versions.
* The `disable_protocols` directive now has `streaming` and `polling` options
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_STDERR` to a non-empty value.
shiny-server 1.5.12
--------------------------------------------------------------------------------
* Upgrade Node.js to 10.15.3.
shiny-server 1.5.11
--------------------------------------------------------------------------------
(No open-source release)
shiny-server 1.5.10
--------------------------------------------------------------------------------
(No open-source release)
shiny-server 1.5.9
--------------------------------------------------------------------------------
* Fix bug with listening on port 80.
shiny-server 1.5.8
--------------------------------------------------------------------------------
* 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".
* Resolve permissions issues when log directory is on an NFS mount with root
squash. The `log_as_user` directive was intended to work for these situations,
but would fail in common configurations. It should now work.
* `log_file_mode` no longer respects the process umask, and the default has been
changed from `0660` to `0640`.
* 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.
shiny-server 1.5.7
--------------------------------------------------------------------------------
* Upgrade to Node v8.10.0.
* Dropped support for Ubuntu 12.04 and SLES 11.
* 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.
* Don't color log output if stdout is not a terminal.
shiny-server 1.5.6
--------------------------------------------------------------------------------
* Dropped support for RedHat/CentOS 5.
* Use HTTPS for Google Fonts on error page, which resolves insecure content errors on some browser when run behind SSL.
(PR #322)
shiny-server 1.5.5
--------------------------------------------------------------------------------
There were no changes in this release. The version was increased just to match Shiny Server Pro.
shiny-server 1.5.4
--------------------------------------------------------------------------------
* Upgrade to Node.js v6.10.3.
* Upgrade to pandoc 1.19.2.1.
* Refactor scheduler code to make enforcement of connection limits more robust.
* Add opt-in clickjacking protection via `frame_options` directive.
* Fix "Error: Can't set headers after they are sent." appearing in the log.
shiny-server 1.5.3
--------------------------------------------------------------------------------
* Upgrade to Node.js v6.10.0.
shiny-server 1.5.2
--------------------------------------------------------------------------------
* Add additional configuration directives `http_keepalive_timeout`,
`sockjs_heartbeat_delay`, and `sockjs_disconnect_delay` to allow working
with very slow connections and large SockJS payloads. (The default values
for these options are the same as in previous versions of Shiny Server.)
shiny-server 1.5.1
--------------------------------------------------------------------------------
* Improve robustness with unfriendly proxy configurations. This had regressed
some time between 1.4.3 and 1.4.7. (PR #263)
shiny-server 1.5.0
--------------------------------------------------------------------------------
* Upgrade to Node.js v6.6.0, 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.
* Fix bug where R processes would not be cleaned up if an HTTP request was
prematurely closed.
shiny-server 1.4.7
--------------------------------------------------------------------------------
* Upgrade to Node.js v0.10.47 (security patches).
* Fix a minor bug where subapps being created after a disrupted-then-restored
SockJS connection, might result in a duplicate connection.
* 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).
shiny-server 1.4.6
--------------------------------------------------------------------------------
(Skipped 1.4.5 for parity with Shiny Server Pro; 1.4.5 was a security release
that was Shiny Server Pro specific.)
* Fix a bug where a 404 response on some URLs could cause the server to exit
with an unhandled exception.
shiny-server 1.4.4
--------------------------------------------------------------------------------
* Upgrade to Node.js v0.10.46 (security patches).
shiny-server 1.4.3
--------------------------------------------------------------------------------
* Add auto-reconnect capabilities. Can be disabled via `reconnect false;`
config option (replaces `disable_reconnect true;`).
* Upgrade to Node.js v0.10.45 (primarily for updated OpenSSL).
shiny-server 1.4.2
--------------------------------------------------------------------------------
* Improve disconnected UI by adding modal with description.
* Added experimental support for reconnecting disconnected sessions. Set
`disable_reconnect false;` to enable the feature.
shiny-server 1.4.0
--------------------------------------------------------------------------------
* Added support for Red Hat Enterprise Linux 7 and Ubuntu 15.04.
* Added `disabled_protocols` to allow administrators to disable arbitrary
SockJS protocols.
* Capture Upstart failures to start Shiny Server successfully.
* Various bug fixes around RHEL/CentOS 7 installers.
* Bug fix: Load fonts over HTTPS.
* Bug fix: Fix installer locale issue for Ubuntu 14.04.

--------------------------------------------------------------------------------
* Added experimental support for Interactive Documents (Shiny + Rmd) via the
rmarkdown package.
* Leverage site_dir when hosting in user_dirs mode; user_dirs will now respect
the directory_index setting and host static assets other than Shiny
applications.
* Provide a more sane handling of LANG by ensuring it's passed through in all
spawning modes and set an environment variable in the startup script on
Ubuntu.
* Bug fix: Restored functionality of sspasswd's `-v` switch.
shiny-server 1.1.0
--------------------------------------------------------------------------------
* Added support for custom page templates -- exposing the ability to customize
the static pages generated by Shiny Server for directory listings or errors.
* Created 'user_dirs' mode and the special ':HOME_USER:' run_as user to replace
'user_apps'.
* Leverage bash when spawning Shiny processes on behalf of other users, as in
'user_dirs' mode.

* 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.)
