Known issues!

This release is by no means perfect. Some complex designs appear to generate bitstreams with timing violations. Passing -nodffe resolves this in some cases. Depends on the exact commit of Yosys and Nextpnr used.

The main reason for publishing this release is that some major changes are coming, and we want to be able to do an alpha relese while most users will by default get a somewhat more stable release. Expect many bugfix and feature releases in the future.

What's Changed

• Fix nanolcd example by @yrabbit in #60
• Add pinless IO treatment by @yrabbit in #61
• Use LEDS_NR in the shift.v example by @yrabbit in #62
• Fix io flags detection. by @yrabbit in #63
• WIP: new vendor ide version support by @yrabbit in #55
• Allow the use of I2C pins iduring fuzzing. by @yrabbit in #66
• Fix base modification. by @yrabbit in #67
• compile attosoc both with and without dffe by @pepijndevos in #65
• Document the longval tables by @yrabbit in #68
• run CI on different yosys/nextpnr versions by @pepijndevos in #69
• Fix the .CST generation in the unpacker by @yrabbit in #73
