Compatibility
Emacs
CIDER supports Emacs 25.1+. More generally we try to support the last 3 major Emacs releases when that’s feasible and doesn’t add a lot of maintenance overhead.
| We pay special attention to supporting whatever Emacs is bundled with the current stable Debian and RHEL GNU/Linux distributions. |
nREPL
CIDER supports nREPL 0.6+.
| We pay special attention to supporting whatever nREPL is bundled with the current stable Leiningen and Boot releases. |
Java
CIDER officially targets Java 8, Java 11 and the most recent rapid release version (e.g. Java 13). More generally speaking - we aim to support all Java releases that are currently officially supported by Oracle.
The requirements for Java are pretty much cider-nrepl's requirements.
|
Clojure
CIDER targets Clojure 1.8+. As Clojure doesn’t have the concept of supported releases we have to get a bit creative to determine the minimum version to target.
The minimum required Clojure version is currently derived using data from the State of Clojure survey. In general we consider a Clojure release eligible for dropping once its usage drops bellow 5%, but we’d not drop support for any release just for the sake of doing it. We’d do it only if this would lessen the maintenance burden or open up the possibility for big CIDER improvements.
Compatibility Matrix
| For a very long time CIDER and cider-nrepl were released in lock-step, but this changed in CIDER 0.18. The actual releases diverged for the first time in CIDER 0.23. |
