v26.7.1

New features

• Configurable Query patterns metric with a fuzzy-search picker, unit-aware totals and instant client-side switching (#264, by @UnamedRus)
• stack_traces_by_thread option to split per-host Perfetto stack tracks by thread (e5fd240)
• Hostname, TID and thread name on Android log events in Perfetto traces (#267, e500805)
• jemalloc JIT and MergeTree arena active/dirty bytes in the memory summary (cc31e4d, 832de39, 747e0ae)
• --cluster without a value implies "default" (a59b1a5)

Performance

• gzip compression for pastila sharing (on by default) — allows sharing large flamegraphs; pastila settings in the settings view (#271)
• Native intra-TracePacket deflate compression for Perfetto traces — ~6x smaller (#266, by @UnamedRus)

Improvements

• No subquery for slow/last query log initial_query_id filtering on ClickHouse 26.3+ (#269)
• CLI options can be repeated, the last one wins (f03605b)
• Settings changed in the settings view apply at runtime; skip_unavailable_shards sent per query instead of via the URL (#272)
• Title and left-heavy view by default for flamegraphs shared via whodidit.you (speedscope) (a6da54c, 9fd5245, d27668b)
• flamelens reverse stack support (#273)
• Settings view regrouped into columns to fit the screen (#271)
• "cancel" queries column hidden by default (37679e9)
• Columns hidden via middle-click are synced to settings (c4f1cbf)
• trace_log.trace_type cast back to Enum8 when merge() resolves it to Int8 (mixed ClickHouse versions with --history) (a6355a7)
• max_block_size and EXPLAIN settings passed via the protocol instead of a SETTINGS clause (avoids duplicates) (#263)

Bug fixes

• USE database not taking effect for EXPLAIN/query execution (f189d8c)
