## Added
- Support to dump BPF program instructions. (#181)
- Support for attaching BPF programs to sockets. (#191)

outside of this crate. (#192)

- Support for bcc 0.17.0
- Now supporting BPF `RingBuf` data structures.
## Changed
- Default bcc version is now 0.17.0

# [0.0.28] - 2020-10-06

- Builder-pattern construction of `BPF` struct.
- Support for passing `CFLAGS` to BPF module creation.
- Builder-pattern construction of `PerfMap`s.
- Support for setting the size of the `PerfMap` ring buffer.
## Changed
- Default bcc version is now 0.16.0
- Some function signatures now return `Result`s to enable better error handling
and reduce internal `unwrap()` usage.

## Added
- Support for `BPF_PERF_ARRAY`.
## Fixed
- `PerfEvent`s are not properly closed on drop.
- BPF `Table` now returns the value for the first entry instead of always
returning zero for the first entry.

## Added
- Support for attaching probes to perf events and related examples.
- Implementation of `get_syscall_fnname` to support in resolving system calls to
function names.
## Changed
- Converted probe construction to a builder-style pattern with new public types
to initialize and attach probes.
