-* Improved diagnostics for native symbols calling other symbols.
-* Refactored **crypto** module to use Nim StdLib's md5 and sha1 module when OpenSSL support is not enabled.
-* Fixed detection of musl executables when running build task.
-* Added **union**, **intersection**, **difference**, **symmetric-difference**, **one?** symbols to **seq** module.
-* Fixed compilation for loaded files and assets.
-* Refacored code to satisfy nimble package structure.
-* Now caching required modules so that their code is executed only once.
-* Added **line-info** symbol returning a dictionary containing the current filename, line and column numbers.
-* Added **dsdelete!**, **dspost!**, **dsput!**, **dswrite!**.
-* **REMOVED** the following symbols because redundant or pointless: **dequote-and**, **dequote-or**, **reverse-expect-dequote** (and **--**), **read**. Also, **apply** no longer works on dictionaries, only quotations.+* Added **dsinit!** symbol.
+* Added **sealed?** and **sealed-sigil?** symbols.
