+ == Erlang 21
|
| |
+
|
| |
+ The default **Erlang** version in Fedora 30 is 21. Notable changes in this version include:
|
| |
+
|
| |
+ * The BEAM interpreter has been completely re-written.
|
| |
+ * The compiler is about 10-20% faster.
|
| |
+ * Enhanced and improved IO handling.
|
| |
+ * All `CORBA` libraries were split off to an independent repository.
|
| |
+ * Insecure cryptographic algorithms were disabled.
|
| |
+ * Non-smp VM removed.
|
| |
+ * New API for logging: `logger`.
|
| |
+ * The `zlib` module has been refactored and all its operations now yield appropriately, allowing them to be used freely in concurrent applications.
