Icinga vs sps: at a glance
What is Icinga?
Icinga 2 is fixing the same API permission holes across every supported branch.
Icinga 2 ships security fixes as simultaneous releases across its 2.14, 2.15, and 2.16 branches, and has now done so twice in five weeks. The 18 August pair - v2.16.5 and v2.15.6, tagged 25 seconds apart - closes an events/* permission bypass on /v1/events and a memory-exhaustion path where a node could crash another using the 1 GB message limit, now capped at 16 MiB for messages from lower in the hierarchy. v2.16.5 additionally repairs an IcingaDB regression introduced in v2.16.0.
What is sps?
sps keeps sanding down sequential Poisson sampling rather than adding to it.
The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.

◆ Current state
Icinga 2 ships security fixes as simultaneous releases across its 2.14, 2.15, and 2.16 branches, and has now done so twice in five weeks. The 18 August pair - v2.16.5 and v2.15.6, tagged 25 seconds apart - closes an events/* permission bypass on /v1/events and a memory-exhaustion path where a node could crash another using the 1 GB message limit, now capped at 16 MiB for messages from lower in the hierarchy. v2.16.5 additionally repairs an IcingaDB regression introduced in v2.16.0.
◆ Where it's heading
The recurring theme is that the API's filter and permission model was more permissive than intended. July's critical release introduced a filter-expression permission so DSL filters in API queries can be restricted per user, with enforcement deliberately deferred to v2.17; August's pair fixes filter expressions on /v1/events not being permission-checked at all. Cluster message handling is being tightened in parallel. The project is clearly working through an audit of the API surface, and it is backporting every finding rather than pushing users onto the newest branch.
◆ Prediction
Enforcement of the filter-expression permission is already scheduled for v2.17, so that release should be the one where the opt-in restrictions become mandatory - expect more backported API permission fixes across all three branches before it lands.

2.5INFRA · APIS
sps keeps sanding down sequential Poisson sampling rather than adding to it.
◆ Current state
The package implements sequential Poisson sampling for survey design, covering inclusion probabilities, proportional allocation, replicate weights, and take-all strata. Recent releases are small and tightly scoped: a divisor method helper, an iterator that draws a sample one unit at a time, automatic selection of the replicate-weight parameter, and repeated performance work on inclusion probability calculation.
◆ Where it's heading
Development is consolidation rather than expansion. Most releases either speed up an existing routine or remove a decision the user previously had to make by hand, such as picking the smallest parameter that keeps replicate weights non-negative. Documentation and tooling get comparable attention to the algorithms, with a dedicated vignette on inclusion probabilities and a recent switch of test and documentation infrastructure. The API surface has been essentially stable across the window.
◆ Prediction
Expect continued small ergonomic and performance releases against the existing function set rather than new sampling designs, which is the pattern every release in this window follows.
