*   Python 3.3+ support via changes to python codebase and ability to specify
    python version via ./configure.

*   Some improvements to GPU performance and memory usage:
    [convnet benchmarks](https://github.com/soumith/convnet-benchmarks/issues/66)
    roughly equivalent with native cudnn v2 performance. Improvements mostly due
    to moving to 32-bit indices, faster shuffling kernels. More improvements to
    come in later releases.

### Чи краща рівночасність за паралелізм? { #is-concurrency-better-than-parallelism }

Ні! Це не мораль історії.

### ¿Es la concurrencia mejor que el paralelismo? { #is-concurrency-better-than-parallelism }

¡No! Esa no es la moraleja de la historia.

### Est-ce que la concurrence est mieux que le parallélisme ? { #is-concurrency-better-than-parallelism }

Nope ! C'est ça la morale de l'histoire.

### Ist Nebenläufigkeit besser als Parallelität? { #is-concurrency-better-than-parallelism }

Nein! Das ist nicht die Moral der Geschichte.
