See the documentation.

Deprecations

• Session store type: hdf5 is deprecated. It is very slow and not distributed.

Others

• gramex.cache.cache_key(*args) converts arguments into a string suitable for use as a cache key

Internal bugfixes

• Session purge should have a different schedule than flush. This will improve performance. This is resolved.
• download.vega.js should be included in package published to pypi. This is resolved.

Stats

• Code base: 24,961 lines (python: 15,161, javascript: 1,438, tests: 8,362)
• Test coverage: 80%

Upgrade

To upgrade Gramex, run:

pip install --verbose gramex==1.34

This downloads Chromium and other front-end dependencies. That may take time.
