Every release, every change.

chainlink-stellar: the USPC NAV feed (data_id 016e0640…) is recorded as raw:USPC instead of an unknown raw:<hex> id, clearing the unknown-symbol alert (#3847).
explorer: /icon stores successful issuer-icon responses in the Cloudflare edge cache, so a cold visitor no longer waits on the issuer's host (#3848).

v0.116.49

completeness: sep41_supply is re-proved weekly beside sep41_transfers instead of in the nightly pass, where its from-genesis re-derive hit the per-source timeout (#3843).
explorer: a read the API sheds with Retry-After of 8 s or less is retried once, so account panels no longer show "warming or failed" for a busy cold read; the site crawl judges each API URL by its last response (#3844).
explorer: links only to asset pages that exist (#3842).

explorer: dead links found by a browser crawl of all three sites are gone: ticker links render as text when no page exists, unregistered sources show an empty state, incident docs link correctly; the crawl runs daily (#3840).
api, explorer: testnet serves its own Circle USDC and asset catalogue, so /assets/usdc and /assets/xlm resolve there (#3839).
xdrjson: muxed auth-credential addresses render instead of an empty string (#3779).
timescale: no-op trade replays stay off compressed chunks (#3825).

explorer: first visits are faster: API preconnect, first-wave preloads on /markets/ and /accounts/{G}, fewer duplicate calls on account and home (#3831, #3834, #3838).
api: the lending pools list carries each pool's summary; lending pools, reserves and the markets sparkline batch are cached (#3832, #3833, #3836).
explorer: account pages read per-account indexes and rollups (claimables, op-type counts, sponsorship buckets, movement partitions) instead of scanning the lake (#3780, #3781, #3807-#3812).
perf: contract, ledger, supply and protocol reads memoised or bounded (#3793, #3794, #3813-#3824, #3826).
ops: G6 page-panel sweep every 30 min, derived-index and fallback alerts, chunk-destroying-call guards, pgBackRest repo options, heavy-job pool floors (#3768-#3778, #3783-#3806).

api: identical in-flight /v1/price/batch rows are resolved once and shared across requests, so the explorer build's sharded identical batches stop queueing behind each other past the 200 ms latency SLO (#3766).

tests: guardscan scanner fixtures build in a temp module (#3765).
docs: config-assertion, incident and six operator docs re-verified; two dead multi-region docs deleted (#3763, #3764).

api: after startup the API warms every asset detail on the top-500 listing once, so the explorer build's first pass after a deploy no longer reads cold and burns the latency SLO (#3759).

docs: archival-node bring-up, Hubble event counts and nine WASM audits re-verified against the code and r1 (#3757, #3760).
