What is BorgBackup?

Borg's long-running 2.0 beta finally landed packs — and warned it dropped back to alpha quality.

Borg runs two trains in the same feed. The 1.4.x line is explicitly a refreshed 1.2 — same features and behaviour, with the riskier changes isolated so they could be tested before shipping — and it has taken over as the recommended branch since 1.2.9 was called the final 1.2 release. The 2.0 line has been in beta since well before this window, at b22 as of July 2026, with every release carrying a do-not-use-on-production warning. b22 introduced packs and the maintainers told users to expect alpha stability despite the beta number.

What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

Borg's long-running 2.0 beta finally landed packs — and warned it dropped back to alpha quality.

◆ Current state

Borg runs two trains in the same feed. The 1.4.x line is explicitly a refreshed 1.2 — same features and behaviour, with the riskier changes isolated so they could be tested before shipping — and it has taken over as the recommended branch since 1.2.9 was called the final 1.2 release. The 2.0 line has been in beta since well before this window, at b22 as of July 2026, with every release carrying a do-not-use-on-production warning. b22 introduced packs and the maintainers told users to expect alpha stability despite the beta number.

◆ Where it's heading

The split is the story: one branch exists purely to keep existing users safe and current, while the other rewrites how data is stored on disk. Packs are the kind of change that determines whether 2.0 ever ships — repository layout affects performance, resumability and every recovery path at once, and the honesty about stability regressing suggests the shakeout is still ahead. The 1.4 line will keep absorbing fixes and low-severity security work in the meantime, and the b18 corruption bug shows why the two trains are kept firmly apart.

◆ Prediction

Expect further 2.0 betas focused on packs stability before anything resembling a release candidate, with 1.4.x continuing to carry routine fixes for production users.

2.5

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.
