What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

- **fixed** — Fix DeprecationHandler version fallback when packaging raises InvalidVersion for unparseable versions
- **fixed** — Refresh cached empty channel notice responses and parse CEP 6 expires_at timestamps
- **fixed** — Fall back to threaded package extraction when process synchronization primitives are unavailable
- **fixed** — Fix CondaHttpAuth.add_binstar_token mangling URLs that end in notices.json by correcting Channel.url() to preserve package_filename when platform is None
- **fixed** — Fix AttributeError when accessing CondaError.guidance, __str__, or dump_map on subclasses that skip CondaError.__init__
- **fixed** — Report extraction errors from process workers when they cannot cross the process boundary, and include process-pool failure causes in debug logs

###### Bug fixes

* Fix `DeprecationHandler` version fallback when `packaging` raises `InvalidVersion` for unparseable versions (e.g. `None` under packaging >=26.3). (#16495)
* Refresh cached empty channel notice responses and parse CEP 6 `expires_at` timestamps. (#16500, #16501)
* Fall back to threaded package extraction when process synchronization primitives are unavailable. (#16512)
* Fix `CondaHttpAuth.add_binstar_token` mangling URLs that end in `notices.json` (or any filename without a platform subdir) by correcting `Channel.url()` to preserve `package_filename` when `platform` is `None`. (#16516)
* Fix `AttributeError` when accessing `CondaError.guidance`, `__str__`, or `dump_map` on subclasses that skip `CondaError.__init__`. (#16534 via #16535)
* Report extraction errors from process workers when they cannot cross the process boundary, and include process-pool failure causes in debug logs. (#16552)
