Hologram patch releases

Hologram v0.8.2

Bug Fixes

• Fix Calendar.ISO.valid_date?/3 undefined when invoking Date.new!/3 in an action (#740)

• Fix client-side Date struct rendering in templates crashing with :lists.flatten/1 error (#742)

• Fix :erlang.list_to_binary/1 handling of nested improper-list iodata (#751)

• Fix :erlang.iolist_to_binary/1 semantics and error handling (#752)

• Fix call graph module edge handling for accurate dynamic call detection (#755)

• Fix protocol dispatch edges not added for new implementations during live reload (incremental call graph patching)

• Fix compiler normalizer to strip import residue aliases from block AST

• Fix Erlang JS function extraction regex to handle comment lines between Start/End markers (#756)

• Fix Biome formatter failing on Windows when file paths exceed cmd.exe command line length limit

Enhancements

• Overhaul call graph traversal for protocols and structs - resulting in more accurate client-side bundles

• Manually port IO.warn/1, IO.warn/2, IO.warn_once/3, and Application.get_env/3 to JavaScript to reduce client-side bundle size

• Add debugging mix tasks: holo.compiler.runtime_mfa_cascades, holo.compiler.page_mfa_cascades

• Include diagnostic details in Biome formatter error messages

Hologram v0.8.3

Backward Incompatible Changes

• Remove mix holo.compiler.page_mfa_cascades and mix holo.compiler.runtime_mfa_cascades tasks

Enhancements

• Compiler groundwork for with expression support (#735)
• Improve compiler call graph accuracy for Date, Time, NaiveDateTime, and DateTime modules

Bug Fixes

• Fix bundle size explosion predominantly affecting Ash apps (#775)

Hologram v0.9.1

A quick patch for a compile-time performance problem recently reported by a user: with deeply nested templates, the Biome formatter could make compilation disproportionately slow and peg CPU. Removing it from the compiler keeps builds fast.

Performance

• Remove the Biome formatter from the compiler to fix exponentially slow compilation with deeply nested templates (#809)

Hologram v0.9.2

Bug Fixes

• Fix SSE response not being halted, raising Plug.Conn.AlreadySentError when Hologram.Router is mounted ahead of another router (#811)
• Fix Hologram.Router raising a “no persistent term” error when Hologram is disabled, breaking mix test (#813)

Hologram v0.9.3

Enhancements

• Support Elixir 1.19 and Erlang/OTP 28 (#835)
• Support Elixir 1.20 and Erlang/OTP 29 (#837)
• Port :string.to_graphemes/1 to JavaScript (#844)
• Port :string.jaro_similarity/2 to JavaScript (#842)
• Port :lists.suffix/2 to JavaScript (#851)

Bug Fixes

• Fix compilation crashing with CaseClauseError when an Erlang dependency uses Elixir-style module names, e.g. luerl (#776)
• Fix client runtime crashing when navigating to or rendering a <Link> for a route that declares a param (#833)
• Fix :erlang.div/2 raising ArgumentError instead of ArithmeticError for invalid arguments (#848)
• Fix cp/1/gc/1 chardata iteration dropping multi-element improper-list tails, affecting :elixir_utils.jaro_similarity/2 (#845)

Hologram v0.10.1

Bug Fixes

• Fix client runtime crashing at startup after unrelated server-side dependency upgrades (#912)
• Fix protocol implementations being bundled based on loaded modules rather than reachable types (#917)
• Fix client runtime crashing in non-secure contexts where crypto.randomUUID() is unavailable (#933)

Security

• Bump plug, cowlib, and phoenix past flagged releases for security advisories (#915, #934)

Hologram v0.11.1

Enhancements

• Reconcile the DOM by keys rather than comment markers, so served HTML and the live DOM hold only the nodes your templates describe (#1021)

• Tie every action to the page it belongs to, so a dispatch can no longer resolve against a page the user has already left (#1047)

Performance

• Paint a navigated page in a single round trip, so client-side navigation is no longer slower than a full document load (#1026)

• Escape binaries in a single pass, removing quadratic string escaping from the term encoder (#1067)

• Send a navigated page’s render as data rather than markup, shrinking the navigation payload (#1068)

• Send a page’s hydration state beside its render instead of nested inside it, dropping a redundant encoding round trip (#1069)

Bug Fixes

• Fix initial page load rebuilding the entire DOM instead of hydrating server-rendered markup (#926)

• Fix the flash of unstyled content caused by the first render rebuilding the document head (#932)

• Fix a serialized </script> in page state truncating the inline mount data script (#959)

• Fix put_subscription in a command being silently dropped on a tab’s first connect (#975)

• Fix :binary.replace/4 letting replacement fun errors escape instead of raising badarg (#980)

• Fix a map comparing equal to any map that contains it (#986)

• Fix subscriptions silently not working with more than one server instance (#992)

• Fix js_import not resolving in a component referenced in broadcast code (#998)

• Fix an action that runs during a render corrupting the DOM (#1001)

• Fix a struct pattern in a clause head being evaluated instead of matched (#1004)

• Fix client-side :maps.find/2 returning the bare value instead of {:ok, value} (#1005)

• Fix actions scheduled before a navigation still running on the new page (#1006)

• Fix reordering a list whose body holds a block corrupting the DOM (#1019)

• Fix elements whose tag name carries case losing DOM identity on initial page load (#1024)

• Fix a realtime stream that dies right after connecting being retried without backoff (#1028)

• Fix realtime connections crashing for several seconds after every server start (#1029)

• Fix two compilations being able to hold the compiler lock at the same time (#1032)

• Fix debounced and throttled dispatches landing on the wrong side of a navigation (#1045)

• Fix an inline script’s action landing on the previous page when the page is reached by a link (#1046)

• Fix asset paths reaching the manifest script unescaped (#1074)

• Fix interpolation inside a <script> element being made safe by altering the value (#1075)

• Fix a binary that is not valid UTF-8 changing on its way to the client (#1076)

• Fix CSS in an inline <style> element reaching the browser entity-encoded (#1100)

• Fix an SVG element built on the client losing its tag name’s case (#1106)

• Fix a prop written as literal text arriving entity-encoded on the server (#1130)

• Fix an integer and a float no longer comparing equal inside a list, tuple or map (#1140)

• Fix a middleware redirect reached by navigating keeping the clicked link’s URL (#1148)

Documentation

• Document that state takes precedence over a same-named prop, and the copy-a-prop-into-state trap that follows from it (#796)

• Add a security policy and a page describing how to report a vulnerability privately (#1112)

• Bring the shipped LLM documentation back in line with the website (#1146)
