v1.20.5 / 2024-10-15
We decided to revert the
testutil
change that made our util functions less error-prone, but created a lot of work for our downstream users. Apologies for the pain! This revert should not cause any major breaking change, even if you already did the work--unless you depend on the exact error message.Going forward, we plan to reinforce our release testing strategy [1],[2] and deliver an enhanced
testutil
package/module with more flexible and safer APIs.Thanks to

v1.20.0
Thanks everyone for contributions!
:warning: In this release we remove one (broken anyway, given Go runtime changes) metric and add three new (representing GOGC, GOMEMLIMIT and GOMAXPROCS flags) to the default
collectors.NewGoCollector()
collector. Given its popular usage, expect your binary to expose two additional metric.Changes
- [CHANGE] :warning: go-collector: Remove
go_memstat_lookups_total
metric which was always 0; Go runtime stopped sharing pointer lookup statistics. #1577- [FEATURE] :warning: go-collector: Add 3 default metrics:
go_gc_gogc_percent
,go_gc_gomemlimit_bytes
andgo_sched_gomaxprocs_threads
as those are recommended by the Go team. #1559- [FEATURE] go-collector: Add more information to all metrics' HELP e.g. the exact
runtime/metrics
sourcing each metric (if relevant). #1568 #1578- [FEATURE] testutil: Add CollectAndFormat method. #1503
- [FEATURE] histograms: Add support for exemplars in native histograms. #1471
- [FEATURE] promhttp: Add experimental support for
zstd
on scrape, controlled by the requestAccept-Encoding
header. #1496- [FEATURE] api/v1: Add
WithLimit
parameter to all API methods that supports it. #1544- [FEATURE] prometheus: Add support for created timestamps in constant histograms and constant summaries. #1537
- [FEATURE] process-collectors: Add network usage metrics:
process_network_receive_bytes_total
andprocess_network_transmit_bytes_total
. #1555- [FEATURE] promlint: Add duplicated metric lint rule. #1472
- [BUGFIX] promlint: Relax metric type in name linter rule. #1455
- [BUGFIX] promhttp: Make sure server instrumentation wrapping supports new and future extra responseWriter methods. #1480
- [BUGFIX] testutil: Functions using compareMetricFamilies are now failing if filtered metricNames are not in the input. #1424

1.19.0 / 2024-02-27
The module
prometheus/common v0.48.0
introduced an incompatibility when used together with client_golang (See prometheus/client_golang#1448 for more details). If your project uses client_golang and you want to useprometheus/common v0.48.0
or higher, please update client_golang to v1.19.0.
- [CHANGE] Minimum required go version is now 1.20 (we also test client_golang against new 1.22 version). #1445 #1449
- [FEATURE] collectors: Add version collector. #1422 #1427
1.18.0 / 2023-12-22
- [FEATURE] promlint: Allow creation of custom metric validations. #1311
- [FEATURE] Go programs using client_golang can be built in wasip1 OS. #1350
- [BUGFIX] histograms: Add timer to reset ASAP after bucket limiting has happened. #1367
- [BUGFIX] testutil: Fix comparison of metrics with empty Help strings. #1378
- [ENHANCEMENT] Improved performance of
MetricVec.WithLabelValues(...)
