tidyr
tidyr replaced separate() with a family that says what it does.
A side-by-side editorial comparison of PySCF and Simple Analytics — release velocity, themes, recent moves, and the top alternatives to consider.
Quantum chemistry package adding whole method families every release.
PySCF is a Python-based quantum chemistry toolkit, and its release cadence is unusually feature-dense: each version lands multiple new electronic-structure methods rather than polishing existing ones. Recent releases have built out the GW/BSE excited-state stack, k-point RPA for periodic systems, higher-order coupled cluster, and multi-state PDFT with analytical gradients. Platform work runs alongside — Windows DLL compatibility, GPU4PySCF interfacing, and configurable einsum backends.
Privacy analytics tightening its API and moving IP blocking off the CDN
The feed stores each change several times — once with the body text captured as the title, once as a clean headline, sometimes a third time with a date prefix. Behind the duplication, three real changes: API v6 with proper interval support while v5 stays unchanged for compatibility, IP blocking moved off the bunny.net CDN so it works on custom domains and applies per site rather than account-wide, and Events Explorer readability work with column truncation, a full-width toggle and collapsible headers.

Two arcs are visible. The methods arc is pushing toward periodic (PBC) parity with molecular calculations — PBC GW, PBC RPA, SOC-ECP for PBC DFT, QM/MM for periodic systems all landed in this window. The infrastructure arc is about getting PySCF to run where it previously did not: Windows, GPUs, alternative tensor-contraction backends.
The PBC catch-up should continue, since each release closes another gap between molecular and periodic implementations of the same method; the entries do not indicate which gap is next.

The work is about removing borrowed constraints. IP blocking inherited the CDN's limits and blast radius; moving it in-house made it per-site and custom-domain compatible. API v6 does the same for time handling — hourly data separates day and hour, weeks and months carry explicit start dates — while keeping v5 stable so nobody is forced to migrate. Both are the moves of a product whose users integrate it and stay.
With v6 shipped alongside an unchanged v5, expect a deprecation timeline for v5 to be the next API announcement, though the entries do not name one.
