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 async MFA detection propagating Task.await/1 reachability through module vertices

• 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)
