.. leading zeros are required for `frontmatter` to treat them as dates
rather than strings, apparently per the YAML specification.
This was done by script:
```py
import re
import datetime
import pathlib
import sys
import frontmatter
rx = re.compile(r'^(\s*)date_added:.*$', re.M)
for path_str in sys.argv[1:]:
print(path_str)
path = pathlib.Path(path_str)
post = frontmatter.load(path)
date_added = post.get("date_added", "")
if isinstance(date_added, datetime.date):
continue
if isinstance(date_added, str):
try:
date_added = datetime.datetime.strptime(date_added, "%Y-%m-%d")
except ValueError as exc:
print(f"Failed to parse date {date_added} in {path_str}: {exc}")
continue
date_added = date_added.date()
content = path.read_text("utf-8")
new_content = rx.sub(lambda m: f"{m.group(1)}date_added: {date_added}", content)
assert content != new_content
path.write_text(new_content, "utf-8")
```

The Evo M51 is an FPGA-enhanced Feather compatible compute module from Alorium Technology that features a 32-bit SAMD51 microcontroller along with an Intel MAX 10 FPGA.
Designed for use as an embeddable system-on-module, all of the standard Feather I/O are also routed to castellated vias along the edge of the board. There are 34 additional castellated digital I/O connected to the FPGA and accessible via the SAMD51.
Most digital I/O connections are routed through the FPGA to and from the primary and castellated I/O. This provides the opportunity for developers to immediately capture inputs or drive outputs from the FPGA without requiring direct interaction with the SAMD controller.
Evo M51 will support Alorium Technology-supplied pre-built FPGA images that target specific application use cases. In addition, designers will have the option to develop their own custom logic blocks and integrate them into the top-level MAX 10 FPGA design.
Evo was specifically designed to support running CircuitPython. It is also programmable with Arduino just like many other boards based upon the SAMD51.

Misc
In order to take full advantage of the additional I/O on Evo M51 using CircuitPython, we have created a custom library bundle that can be found on the Alorium Technology GitHub page:
