## v1.87.x long-time support release (LTS)
* BUGFIX: [vmselect](https://docs.victoriametrics.com/vmselect.html): properly determine time range search for instant queries with too big look-behind window like `foo[100y]`. Previously, such queries could return empty responses even if `foo` is present in database.
* BUGFIX: properly return errors from [export APIs](https://docs.victoriametrics.com/#how-to-export-time-series). Previously these errors were silently suppressed. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5649).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly process queries with too big lookbehind window such as `foo[100y]`. Previously, such queries could return empty responses even if `foo` is present in database. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5553).
* BUGFIX: [MetricsQL](https://docs.victoriametrics.com/MetricsQL.html): properly handle possible negative results caused by float operations precision error in rollup functions like rate() or increase(). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5571).
