Improvements

defmt

• #345 reduces code size by avoiding 64-bit arithmetic in LEB encoding
• #347 documents the grammar of defmts current format parameter syntax
• #350 panic-probe now uses defmts Display2Format to log panic messages. In consequence, panic messages won't get truncated anymore.
• #351 allows tools to distinguish user-controlled format strings from generated ones
• #354 adds f64 support
• #355 clarifies the docs on Write::write

probe-run

• #133 removes supported defmt version: c4461eb1484... from -h / ` –help` output. Thank you @Javier-varez!

Fixes

• #134 updates probe-run's defmt dependencies in order to make features presented in changelog #13 accessible. Thank you @mattico!

Version Update Notification

We've bumped probe-run to v0.1.9 on crates.io.

Note that probe-run depends on defmt-decoder, defmt-elf2table and defmt-logger, which means that its git version may pull in breaking changes to defmt, as the defmt main branch is currently on its way towards a v0.2.0 release.
