Major version bump breaks incompatible companion dev dependencies
High Severity
Bumping svelte from 3.59.2 to 5.53.5 without updating companion dev dependencies breaks builds and tests. @sveltejs/vite-plugin-svelte at 1.4.0 was built for Svelte 3 (depends on svelte-hmr@^0.15.1) and is incompatible with Svelte 5's completely rewritten compiler and runtime. @testing-library/svelte at ^3.2.1 uses Svelte 3/4 component instantiation APIs (new Component()) that no longer exist in Svelte 5 — version 5.x of this library is needed. Tests also use component.$set() which was removed in Svelte 5. The vite config alias mapping svelte to svelte/internal is broken since svelte/internal no longer exists in Svelte 5 (replaced by svelte/internal/client).

Svelte 5 removes type import paths breaking build
High Severity
Bumping svelte to 5.53.5 breaks the production type build (build:types:core via tsc). The source files types.ts, config.ts, and preprocessors.ts import PreprocessorGroup from svelte/types/compiler/preprocess and CompileOptions from svelte/types/compiler — these export paths were removed in Svelte 5, where both types are now exported from svelte/compiler. Since tsc resolves types against the devDependency, the type declaration build will fail.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting If you change your mind, just re-open this PR and I'll resolve any conflicts on it. |

closed because we explicitly listed these versions as dev dependencies. Nothing here ships to users |

Bug: The trackUpdates: true feature silently fails in Svelte 5's default runes mode because it relies on deprecated beforeUpdate/afterUpdate hooks, leading to a loss of performance tracking.
Severity: MEDIUM
Suggested Fix
Update the performance tracking implementation to be compatible with Svelte 5's runes mode, potentially by using a different mechanism than the deprecated beforeUpdate and afterUpdate hooks. Alternatively, if supporting this feature in runes mode is not feasible, explicitly document this limitation and throw a more informative error when trackUpdates: true is used in an unsupported Svelte 5 environment.

agent.
Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not
valid.
Location: packages/svelte/package.json#L52
Potential issue: The package advertises support for Svelte 5, which defaults to "runes"
mode. However, the performance tracking feature enabled by `trackUpdates: true` relies
on `beforeUpdate()` and `afterUpdate()` lifecycle hooks. These hooks are deprecated in
runes mode and throw an error. The implementation in
`packages/svelte/src/performance.ts` catches this error and suppresses it with only a
debug warning. As a result, for users on Svelte 5, the `trackUpdates` feature will
silently fail to record update performance spans, leading to an unexpected loss of
functionality without a clear error message.

Incompatible sveltekit vite-plugin-svelte for Svelte 5
High Severity
Bumping svelte to ^5.53.5 while @sveltejs/vite-plugin-svelte stays at ^3.0.0 (resolves to 3.1.2) creates an incompatibility. Version 3.x of the vite plugin was built for Svelte 4 and does not support Svelte 5's compiler API. This breaks the sveltekit package's dev/test pipeline. The plugin needs to be updated to at least v4+ for Svelte 5 compatibility.
