fellingdater vs ManageEngine RecoveryManager Plus: at a glance
What is fellingdater?
Went from estimating felling dates to doing the crossdating that produces them.
fellingdater estimates when a tree was felled from sapwood measurements, the core inference in dendrochronological dating of timber. Version 1.0.0 passed rOpenSci review with that scope, and the 2024 releases were mostly about the accompanying JOSS paper and user-supplied sapwood datasets. Version 1.2.0 changed the package's remit substantially, adding an entire trs_* family for tree-ring series handling: crossdating with multiple statistical measures, the Hollstein and Baillie-Pilcher t-value transformations, parallel variation percentages, synthetic series generation, and dated-series plotting.
What is ManageEngine RecoveryManager Plus?
RecoveryManager Plus keeps widening its backup coverage across the Microsoft identity estate.
RecoveryManager Plus is a backup-and-recovery tool for Active Directory and Microsoft 365, and it is the most feature-active of the ManageEngine set here. Recent builds add real backup coverage — AD sites and subnets, Entra ID local admin passwords, S3-compatible repositories, SIEM audit forwarding, and Entra ID BitLocker recovery keys — alongside CVE patches and RemCom agent hardening. Build 6322 is the quietest of the run: a single fix for restarts triggered by an outdated ExchangeOnlineManagement PowerShell module during Microsoft 365 enumeration.

Went from estimating felling dates to doing the crossdating that produces them.
◆ Current state
fellingdater estimates when a tree was felled from sapwood measurements, the core inference in dendrochronological dating of timber. Version 1.0.0 passed rOpenSci review with that scope, and the 2024 releases were mostly about the accompanying JOSS paper and user-supplied sapwood datasets. Version 1.2.0 changed the package's remit substantially, adding an entire trs_* family for tree-ring series handling: crossdating with multiple statistical measures, the Hollstein and Baillie-Pilcher t-value transformations, parallel variation percentages, synthetic series generation, and dated-series plotting.
◆ Where it's heading
The package has expanded backwards along the workflow. It began at the last step — given dated series, estimate the felling date — and 1.2.0 added the step before it, establishing those dates by crossdating in the first place. Version 1.2.1 is early polish on that new surface: axis control, non-syntactic column names, encoding safety in read_fh(). The direction is a single package covering the chain from raw ring widths to a felling-date estimate.
◆ Prediction
Expect the trs_* family to keep accumulating polish and additional crossdating statistics, since it is barely a year old and 1.2.1 was already fixing its plotting and top_n behaviour. Whether the two halves of the package get unified into one workflow interface is the open question the entries do not answer.
ManageEngine RecoveryManager Plus
2.5ANALYTICS
RecoveryManager Plus keeps widening its backup coverage across the Microsoft identity estate.
◆ Current state
RecoveryManager Plus is a backup-and-recovery tool for Active Directory and Microsoft 365, and it is the most feature-active of the ManageEngine set here. Recent builds add real backup coverage — AD sites and subnets, Entra ID local admin passwords, S3-compatible repositories, SIEM audit forwarding, and Entra ID BitLocker recovery keys — alongside CVE patches and RemCom agent hardening. Build 6322 is the quietest of the run: a single fix for restarts triggered by an outdated ExchangeOnlineManagement PowerShell module during Microsoft 365 enumeration.
◆ Where it's heading
The direction is coverage expansion: methodically extending what can be backed up and restored across on-prem AD and Entra ID, while broadening cloud storage targets and operational integrations. The dependence on Microsoft's own PowerShell modules is the cost of that coverage, and 6322 shows where it bites — a stale module on the customer's side takes the product down mid-enumeration. Feature builds and pure-fix builds alternate at roughly a two-month cadence, so a single-issue build reads as a gap between feature cycles rather than a slowdown.
◆ Prediction
Expect continued expansion of Entra ID and cloud-native backup coverage and more storage-target options, with security patches folded into each build; the next build carrying a Features section is due on the cadence this feed has held.
