Eldev 0.10

This release comes with several new features:

• Docker support lets you run Eldev commands easily. You can use both “standard” Silex’s Emacs images and your own.
• Partial support for Ecukes tests; only “script” (a.k.a. “batch”) mode is supported.
• You can now use several testing frameworks at once in the same project. This is needed by some larger projects.

Less important changes:

• Updated package-lint integration: Eldev will now set package-lint-main-file correctly for you.
• Yet more backtrace formatting improvements. In particular, backtrace formatting is now more similar across different Emacs versions.
• Several fixes.
