The following versions were released on 12th December 2016:
- 3.1.17 (changelog, upgrade documentation) – Rudder 3.1 is currently the ESR version of Rudder. It will be maintained 6 months after the next ESR release is announced.
- 3.2.10 (changelog, upgrade documentation) – Rudder 3.2 was the latest release before 4.0, and it will reach end of life the 10th February 2017. We recommend that any installations still using 3.2 be upgraded to Rudder 4.0 as soon as possible.
- 4.0.1, followed the 20th December by 4.0.2 (changelog, upgrade documentation) – Rudder 4.0 is currently the latest stable release of Rudder. It will be maintained 3 months after the next major release comes out.
These are bug fix releases, and all installations should be upgraded when possible. We are impatient to hear your feedback, be it comments, questions on Twitter (@RudderProject) or on IRC (#rudder on Freenode), bug reports or feature requests on the bug tracker (or of course GitHub pull requests).
Note: The 4.0.1 release contained an inconvenient warning message in the scripts that regularly checks Rudder agent state (#9799), and a bug in the display of the “Download a file from the shared folder” Directive (#9804), which lead to quickly release the 4.0.2 version.
The 4.0.1 and 4.0.2 releases fix some rough edges of the initial 4.0 release. No major issues have been reported, and 3.2 users should consider upgrading to 4.0 soon (as support will end 10th February 2017).
The following important bugs were fixed:
- [#9402, 3.1, 3.2 and 4.0] The promises were not updated when the node properties were updated using the API, which lead to out-of-sync node properties on the nodes.
- [#9761, 3.1, 3.2 and 4.0] It is now possible to upgrade to a specific version (that may not be the latest) in the apt and rpm package techniques, as well as in the package_install* generic methods.
- [#9751, 3.2 and 4.0] No error output in “rudder agent update” when the agent could not download configuration from its policy server
- [#9691, 4.0] The “node.env” special variable containing the environment variables on the node was broken
These releases include some new features:
- [#8127, 3.1, 3.2, and 4.0] The inventories are now checked on agent side, just after their creation, to avoid sending broken inventories. It avoids having to wait for 24 hours when the first inventory after installation is done before all necessary information are available.
The documentation have also been improved:
- Added general documentation about file templating in ncf/Rudder, and specific sections for mustache and jinja2 templating
- Added doc for the file_replace_line generic method in ncf
- Updated doc about networking security in Rudder for 4.0, including the new networking protocol and acls
- Added doc about the audit mode in Rudder 4.0
