Fixed the Node http adapter clobbering a user-supplied Host header when forwarding through a proxy. axios was unconditionally rewriting options.headers.host to the request URL's hostname:port, making it impossible to route a proxy to a virtual host that differed from the request URL. The fix only sets the default Host header when the caller has not already provided one (case-insensitive match on host/Host/HOST). Closes #10805.

Made the 2022.3 @computed decorator lazy in MobX core. ComputedValue is now created on first read of the decorated getter instead of eagerly during instance construction, so getters that are never accessed on a given instance no longer allocate. Threaded the laziness through getObservablePropValue_, setObservablePropValue_, getAtom, and isObservableProp so existing call sites Just Work. Closes #4616.

Extended the lazy-decorator work from #4639 to the 2022.3 @observable accessor decorator (requested by the maintainer). The accessor init callback no longer eagerly constructs an ObservableValue for every decorated field on every instance; instead it registers a factory on the admin's new lazyObservableKeys_ map, and materializeLazyObservable_ instantiates the ObservableValue on first read/write/observe via getObservablePropValue_, setObservablePropValue_, and getAtom. isObservableProp checks lazyObservableKeys_ so fields still report as observable before first read, and the post-read hot path stays a single Map lookup. Benchmarks on a 50k-instance × 10-field class show construction allocation roughly halved (~224 MB → ~119 MB) for sparse-access workloads. Full suite green (1043 passing) and type checks clean. Closes #4616.

Fixed a regression introduced by the lazy @computed work in #4639: isComputedProp returned false for a lazily-decorated computed property before its first read, because the ComputedValue is no longer created until the getter is first accessed. The check now also consults the admin's lazyComputedKeys_ so a decorated computed reports correctly as a computed property even before it has been materialized.

Fixed an overlay-injection crash in the Vue DevTools Vite plugin under strict Trusted Types CSP. With `require-trusted-types-for 'script'` enforced, assigning a plain string to script.src (a Trusted Types sink) was blocked before the app's own default policy could register, since the overlay is injected via head-prepend and runs ahead of the entry module. The fix wraps the overlay URL through a named vue-devtools TrustedScriptURL policy when window.trustedTypes is available, with a plain-string fallback otherwise. Closes #1086.

Fixed silent dropping of valid runtime prop types in defineProps when a Vue ref-wrapper type appears in a union and the vue import cannot be resolved by the SFC compiler (e.g. the type lives in a separately-built consumed package). resolveTypeReference was throwing inside inferRuntimeType, the top-level catch collapsed the whole branch to UNKNOWN_TYPE, and the resulting filtering dropped real types like Array — producing "Invalid prop: type check failed" warnings at runtime for valid values. The fix catches the resolution failure locally inside the TSTypeReference case and adds built-in fallbacks for Ref, ShallowRef, ComputedRef, WritableComputedRef, MaybeRef<T>, and MaybeRefOrGetter<T>, mirroring existing handling for Promise / Date / Map. Closes #14729.

Reported a regression in defineProps<T>() runtime type inference after upgrading Vue from 3.5.21 to 3.5.31: a union involving MaybeRef<OptionItem[]> lost its Array branch in the generated runtime props, so passing arrays triggered "Invalid prop: type check failed" warnings even though the source TS type allowed them. Provided a minimal reproduction and isolated the regression to SFC type-to-runtime inference for ref-wrapper unions; tracked and fixed by PR #14758.

Fixed ESP32 Arduino core 3.x (IDF 5.x) compatibility for the LilyGo 4.7" e-paper display library. Resolved 5 build/runtime issues: missing esp_attr.h and gpio_struct.h includes, RMT TX driver rewrite for IDF 5 driver_ng API, JPEG feed_buffer type mismatch, and uninitialized LCD clock source causing runtime panic.

Fixed an infinite loop bug in the LilyGo EPD47 font renderer caused by invalid UTF-8 bytes (e.g. bare 0xB0). next_cp() would stall forever when utf8_len() returned 0 for a continuation byte. Added a guard to skip bad bytes and return U+FFFD, preventing the hang and undefined behaviour.

Custom firmware for LilyGo 4.7" e-paper display (EPD47-S3) that shows property information with Hindi date, moon phase, and touch-triggered jokes. Built with C for ESP32-S3.
