* FEATURE: add `tfirst_over_time(m[d])` and `tlast_over_time(m[d])` functions to [MetricsQL](https://victoriametrics.github.io/MetricsQL.html) for returning timestamps for the first and the last data point in `m` over `d` duration.
* FEATURE: enforce at least TLS v1.2 when accepting HTTPS requests if `-tls`, `-tlsCertFile` and `-tlsKeyFile` command-line flags are set, because older TLS protocols such as v1.0 and v1.1 have been deprecated due to security vulnerabilities.
* FEATURE: support `extra_label` query arg for all HTTP-based [data ingestion protocols](https://victoriametrics.github.io/#how-to-import-time-series-data). This query arg can be used for specifying extra labels which should be added for the ingested data.
* FEATURE: vmbackup: increase backup chunk size from 128MB to 1GB. This should reduce the number of Object storage API calls during backups by 8x. This may also reduce costs, since object storage API calls usually have non-zero costs. See https://aws.amazon.com/s3/pricing/ and https://cloud.google.com/storage/pricing#operations-pricing .
* BUGFIX: properly parse escaped unicode chars in MetricsQL metric names, label names and function names. See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/990
* BUGFIX: override user-provided labels with labels set in `extra_label` query args during data ingestion over HTTP-based protocols.
