[ANN] Clojure 1.7.0-RC2

[Alex Miller]

Clojure 1.7.0-RC2 is now available.

Try it via

- Download: https://repo1.maven.org/maven2/org/clojure/clojure/1.7.0-RC2/

- Leiningen: [org.clojure/clojure "1.7.0-RC2"]

1.7.0-RC2 has the following changes since 1.7.0-RC1:

1) CLJ-1735 - Throwable->map was missing docstring

2) CLJ-1237 - reduce gives a StackOverflow for seqs that switch back and forth between chunked and unchunked many times

This was an old problem that was amplified in 1.7, but has now been fixed.

3) CLJ-1738 - Seqs over Java iterators that return the same mutating object on every next() call

Seqs are fundamentally incompatible with Java iterators that return the same mutating object on every call to next().  Some Clojure libraries incorrectly rely on calling seq on such iterators. In 1.7, iterator-seqs are chunked, which will cause many of these incorrect usages to return incorrect results immediately. The `seq` and `iterator-seq` docstrings have been updated to include an explicit warning. Libraries that incorrectly use `seq` and `iterator-seq` will need to be fixed before running against 1.7.

4) CLJ-1745 - Exceptions thrown from macros wrapped in additional CompilerException

This was a regression from CLJ-1169 and most of that change has been rolled back.

For a full list of changes since 1.6.0, see: https://github.com/clojure/clojure/blob/master/changes.md

Please give it a try and let us know if things are working (or not). The more and quicker feedback we get, the sooner we can release 1.7.0 final!

Migrated a library from cljx to reader conditionals and tested it with both RC1 and RC2, everything works perfectly.

 

Thank you for your work on Clojure and looking forward to the final release.

Thanks Alex (hope you had a great vacation)!  Everything is looking good for us with RC2.

After some quick testing, everything is looking good for me. I will pound on it more heavily this weekend, and report back if that changes, although I do not expect it to. Thanks!

[Magnar Sveen]

Tested RC2 in a project with a lot of .cljc going on - seems to be working fine.

Hi,

We've been trying out RC2 in production with no issues to report. (The last hiccup we had was back with CLJ-1738 - Seqs over Java iterators but have since reworked the offending Java iterators.) 

Cheers,

Ted

After using it all weekend, everything looks good for me. Thanks!
