# v0.24.0

Implements a major refactoring of on-demand metrics computation in which each worker container picks up a single sample's worth of feature computation at a time. This is organized with a simple PostgresQL table considered as a task queue, and database notifications. Now all computations for a given sample begin from a database query for the same compressed binary payload representing phenotype and location data for all cells. The TCP client/server model for dispatching specific feature computations to different services is deprecated.

In the grid, each *pair* of phenotypes is shown with the fraction of cells expressing *both* phenotypes. For example, the fraction of cells that are both **CD3+ CD4+ FOXP3+** and **CD3+** is 16.53%, the same as the fraction of cells that are **CD3+ CD4+ FOXP3+**, as expected since **CD3+** is part of the signature of this phenotype (the T regulatory cells).

The new cell count for each phenotype is now shown, together with the new percentage, relative to the selection. In this case the Tc fraction approximately doubled, to **6996** cells (shown in green). This increase is assessed using the Fisher test (the entire contingency table is also shown, for reference). The test verifies that the increase is highly statistically significant in this case, as expected.
