## [v0.0.10] - 2026-02-22

This version comes with a dynamic thread pool and an improved API.

### Added
- New ergonomic API using exported functions like `async { ... }`, `fiber { ... }`, and `await( $target )`.

### Changed
- Refactored native thread pool to use cond vars (`PARA_COND_*`) instead of busy polling, reducing idle CPU usage to near zero.
- Switched to a global job queue for the thread pool for better load balancing across worker threads.
- Reduced default fiber stack size from 4MB to 512K.
- Worker threads are now only spawned when the first asynchronous job is submitted.
- Increased `MAX_FIBERS` limit to 1024.
- Expose thread pool config with `set_max_threads` and `max_threads`.

## [v0.0.9] - 2026-02-21

Asynchronous HTTP::Tiny is basically a semi-automatic footgun.

### Fixed
- Resolved `AvFILLp(av) == -1` and `!AvREAL(av)` assertion failures in `Perl_pp_entersub` on `DEBUGGING` builds of Perl. This was fixed by ensuring Slot 0 (the argument array) of the next pad depth is correctly initialized during fiber context switches.

### Changed
- Increased fiber stack size to 4MB to provide better support for deep Perl calls and regex operations. This is a temp solution.

## [v0.0.8] - 2026-02-19

All the remaining failing smokers all had old versions of Affix and sure enough when I installed v1.0.6, I saw the same failure. Always the most obvious thing...

### Changed
- Require Affix v1.0.7

## [v0.0.7] - 2026-02-18

Another dist targetting a specific CPAN smoker. I cannot replicate the failure in https://www.cpantesters.org/cpan/report/f0ca1d14-0cfa-11f1-9988-e7d94c615303, so I'm just trying different things...

### Fixed?
- Arguments passed to a fiber might not be released until the fiber object was destroyed.

## [v0.0.6] - 2026-02-18

### Fixed
- Resolved assertion failures in `Perl_cx_popsub_args` and `Perl_pp_entersub` when running on a `DEBUGGING` build of Perl. This was fixed by ensuring `CvDEPTH` and pads are correctly restored during context switches. (I hope...)

### Added
- Added `--debug` build to GitHub Actions matrix to ensure future compatibility with Perl debugging builds.

### Changed
- Refactored `swap_perl_state` to be more robust regarding Perl's internal stack management.

## [v0.0.5] - 2026-02-18

### Changed
- I'm honeslty just throwing stuff at the wall. Between my local machines and GH CI workflows, I cannot replicate some of the failures I'm seeing from smokers which makes them virtually impossible to resolve.

## [v0.0.4] - 2026-02-17

### Changed

  - Attempt to only spawn max X threads in `t/006_parallel.t` where X is 3 or the `get_thread_pool_size()`? See https://www.cpantesters.org/cpan/report/ecf1410e-0c46-11f1-8628-aee76d8775ea
  - Recalculate `PL_curpad = AvARRAY(PL_comppad)` in `swap_perl_state`? See https://www.cpantesters.org/cpan/report/e7244bd8-0c44-11f1-b3ab-94362698fc84

## [v0.0.3] - 2026-02-17

### Changed
  - Adding an optional timeout to `await_read` and `await_write`.
  - Allow fibers to return complex data (AV*, HV*).

## [v0.0.2] - 2026-02-17

### Fixed
  - Fixed segfault in `coro_yield` by adding NULL checks for destroyed or missing fibers.
  - Resolved stall in exception handling by introducing `last_sender` tracking to prevent `parent_id` cycles.

### Changed
  - Made unit tests a lot more noisy

## [v0.0.1] - 2026-02-16

### Changes
  - It exists! It shouldn't but it does.
