0.1.34 (April 14, 2022)
This release includes bug fixes for the "log" support feature and for the use of both scoped and global default dispatchers in the same program.
Fixed
- Failure to use the global default dispatcher when a thread sets a local default dispatcher before the global default is set (#2065)
- log: Compilation errors due to
async
block/fn futures becoming!Send
when the "log" feature flag is enabled (#2073) - Broken links in documentation (#2068)

0.1.33 (April 9, 2022)

span or an event.
Added
Fixed

wasm32
) (#2060)

0.1.32 (March 8th, 2022)
This release reduces the overhead of creating and dropping disabled
spans significantly, which should improve performance when no tracing
subscriber is in use or when spans are disabled by a filter.
Fixed
- attributes: Compilation failure with
--minimal-versions
due to a too-permissivesyn
dependency (#1960)
Changed
0.1.31 (February 17th, 2022)

values using the valuable
crate. See this blog post for

macro for testing if a span or event
would be enabled.
