 Available build templates:
-- `conda/micromamba:v1` - Default Conda build using Micromamba 1.x
-- `conda/micromamba:v2` - Multi-stage build using Micromamba 2.x
+- `conda/micromamba:v1` - Single-stage build using Micromamba 1.x
+- `conda/micromamba:v2` - Multi-stage build using Micromamba 2.x (default for Conda packages)
+- `conda/micromamba:v2-fast` - Like `conda/micromamba:v2`, with the Conda environment split into multiple image layers grouped by package, each under 512 MB. Docker images only
 - `conda/pixi:v1` - Multi-stage build using Pixi package manager
+- `conda/pixi:v1-fast` - Like `conda/pixi:v1`, with the Conda environment split into multiple image layers grouped by package, each under 512 MB. Docker images only
