Introductions

Announcements
- (JL) September releases are coming!
- conda (23.9.0)
- conda-build (3.27.0)
- conda-libmamba-solver (23.9.0)
- Jaime, Ken and I are planning to tag the releases this week and likely will release to defaults next week (depending on packaging queue). We’ll keep an eye on the conda-forge feedstock as well, as always.
- Please don’t hesitate to trial the canaries via:
conda install -c conda-canary/label/rc-conda-23.9.x condaconda install -c conda-canary/label/rc-conda-build-3.27.x conda-buildetc.conda install -c conda-canary/label/dev conda-libmamba-solver(relase branch not yet created)
- IMPORTANT (get ready!)
- Special announcement about rollout of default solver switch to
libmamba(TLDR; It'll come in an extra special release conda 23.10.0!)
- Special announcement about rollout of default solver switch to
- (DH) conda-index 0.3.0 deployed to defaults, conda-forge.
- Provide run_exports.json
- Compact json on conda-forge reduces uncompressed repodata.json size by 27%
- CDN outage (we forgot to re-enable the
cronjob. 😬)
- (MM) Updates on caching for CDN-synced channels on anaconda.org
- Initial test run was very successful
- We will migrate CDN-synced channels to the new cache over the upcoming weeks (no format changes!)
- Other channels will follow later
- (JRG) conda-libmamba-solver 23.9 goodies for the curious:
- Simpler logic, easier to maintain, closer to mamba while respecting the good parts of conda classic. Details of deviation in the docs: https://conda.github.io/conda-libmamba-solver/libmamba-vs-classic/#intentional-deviations-from-classic
- Faster repodata loading! (30% or so)
- No more pin overrides. We closed a 4-digit issue with that one.
- Overall, feels faster too. See QA notes: https://hackmd.io/GdQoVv3ZSNCj_na6UBJE2A. Hot caches allow solves in <2s.
New Agenda Items
- (KO) release tooling (rever) is no longer actively maintained
- last released 2 years ago
- effort to revive a year ago fizzled out
- should we be focusing on using alternative tools (e.g. cranko)?
- will bring this up next week at conda-forge community meeting
- JRG: conda-smithy release via rever but I'd say the team would be happy to change to something simpler too. A good policy on PR titles would go a long way towards simplification.
- (DH) Possible for jlap CEP to get a vote?
