authentik vs mpactr: at a glance
What is authentik?
authentik 2026.8 ships: Actors, domain-joined Agents, and a push past browser-mediated SSO
2026.8.0 is out, closing a seven-candidate train that ran through early August. The GA tag itself is the last cherry-pick batch — SCIM group membership removals, a proxy redirect that preserves query strings, session deletion on user deactivation — but the release it finalizes is where the substance lives: an Actors primitive in core, an enterprise Agent requiring a domain join and its own API scope, OAuth2 token exchange delegation, and a CAS source integration.
What is mpactr?
mpactr spent two spring releases normalizing case in metadata after users kept tripping on it.
mpactr filters mass-spectrometry peak tables — removing contaminants, ion duplicates and low-reproducibility features before downstream metabolomics analysis — with a data.table and Rcpp core. Development is slow and the recent releases are small. The May pair both address the same friction: column names and imported table names arriving in inconsistent case and failing to match.

◆ Current state
2026.8.0 is out, closing a seven-candidate train that ran through early August. The GA tag itself is the last cherry-pick batch — SCIM group membership removals, a proxy redirect that preserves query strings, session deletion on user deactivation — but the release it finalizes is where the substance lives: an Actors primitive in core, an enterprise Agent requiring a domain join and its own API scope, OAuth2 token exchange delegation, and a CAS source integration.
◆ Where it's heading
Two threads converge in this major. The identity surface keeps broadening at the protocol edge — CAS, WS-Fed, token exchange delegation, on-behalf-of — while the enterprise tier grows an endpoint story that reaches machines and devices rather than browser sessions. The RC train's shape reinforces it: six candidates fired in one day on CI and docs, then one heavy candidate carrying the features, then a fix-only close. That is release engineering hardened around a major, not a routine point release.
◆ Prediction
With Agents and Actors now GA rather than cherry-picks, the next branch should build out what they enable — device-conditioned policies or agent-brokered credentials — while 2026.8.x settles into backport patches.
mpactr
0.0INFRA · APIS
mpactr spent two spring releases normalizing case in metadata after users kept tripping on it.
◆ Current state
mpactr filters mass-spectrometry peak tables — removing contaminants, ion duplicates and low-reproducibility features before downstream metabolomics analysis — with a data.table and Rcpp core. Development is slow and the recent releases are small. The May pair both address the same friction: column names and imported table names arriving in inconsistent case and failing to match.
◆ Where it's heading
The package is stabilizing its input contract rather than growing its filtering methods. Metadata column names are now forced lowercase inside import_data() regardless of how the file was written, imported peak_tables names not present in the injection column are lowercased too, and get_meta_data() was renamed to get_metadata() in the same pass. Before that the work was infrastructural — Rcpp introduced to speed up filtering, data.table moved from Depends to Imports, and memory errors cleared so the package passes Valgrind and both sanitizers. Note the earliest entry compares against a v1.0.0 tag that precedes 0.1.0 in the repository, so version ordering in this feed is not reliable.
◆ Prediction
The case-normalization work has now touched both metadata columns and peak table names across two consecutive releases, which suggests the input-matching problem is not fully closed and a third pass is plausible. Nothing in these entries points to new filtering methods.
