The minimum Elixir version requirement is raised from ~> 1.9 to ~> 1.14 to match Ecto's minimum. Dependency ordering now respects :requires instead of an unordered MapSet, duplicate dependency declarations emit a warning, and several strict: true crashes involving nested nil parameters are fixed. Internal changes include an O(n·m) to amortized O(n) refactor and new CI on Elixir 1.14/1.19.4. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the minimum Elixir version required by Composite v0.7.0? Composite v0.7.0 requires Elixir ~> 1.14 as its minimum version, up from ~> 1.9 in earlier releases. This change was made to match Ecto's own minimum Elixir version requirement, meaning projects on older Elixir versions must upgrade before adopting this release. _daily.dev helps developers track dependency version bumps like this before they break a build._ ### How do I avoid passing an unchanged Ecto query to Repo.all/1 when using Composite? Use the new Composite.apply_tagged/1 or apply_tagged/3 functions introduced in version 0.7.0, which return :unchanged when the resulting query compares equal (==) to the input, or {:changed, query} otherwise. This lets calling code short-circuit and skip an unnecessary Repo.all/1 call on an unmodified query. _Elixir developers optimizing Ecto query pipelines can follow library updates like this on daily.dev._ ### Why did dependency loading order change in Composite's dependency/4 macro? The previous MapSet-based implementation for handling dependency/4 declarations did not preserve declaration order, so dependencies could load out of sequence. Version 0.7.0 fixes this so dependencies now load in the order specified by :requires, and declaring the same dependency name twice emits an IO.warn/1 message while still overwriting the previous loader. _daily.dev keeps developers current on library fixes that change dependency behavior like this._ ## Similar posts on daily.dev - [Elixir v1.20.0-rc.2 released](https://daily.dev/posts/elixir-v1-20-0-rc-2-released-vo8dwwpw4) · Elixir Forum · 1 upvotes · 0 comments - [Release v0.9.0 · fuelen/seed\_factory](https://daily.dev/posts/release-v0-9-0-fuelen-seed-factory-b8rwahime) · ElixirStatus · 0 upvotes · 0 comments - [Elixir v1.19 released: enhanced type checking, broader type inference, and up to 4x faster compilation for large projects](https://daily.dev/posts/elixir-v1-19-released-enhanced-type-checking-broader-type-inference-and-up-to-4x-faster-compilati-rc2s8j4bd) · Elixir · 22 upvotes · 0 comments - [Elixir v1.19.3 released](https://daily.dev/posts/elixir-v1-19-3-released-rdvbiq3r9) · Elixir Forum · 2 upvotes · 0 comments - [Release v0.9.0 · elixir-error-tracker/error-tracker](https://daily.dev/posts/release-v0-9-0-elixir-error-tracker-error-tracker-b1rl9iyou) · ElixirStatus · 0 upvotes · 0 comments --- Tags: [#elixir](https://daily.dev/tags/elixir), [#ecto](https://daily.dev/tags/ecto) [View this post on daily.dev](https://daily.dev/posts/release-v0-7-0-fuelen-composite-yrw1mbzij) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Release v0.7.0 · fuelen/composite","url":"https://daily.dev/posts/release-v0-7-0-fuelen-composite-yrw1mbzij","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/release-v0-7-0-fuelen-composite-yrw1mbzij"},"datePublished":"2026-08-22T18:18:45.987Z","dateModified":"2026-08-22T18:19:05.308Z","description":"Composite v0.7.0 adds apply_tagged/1 and apply_tagged/3 functions that return :unchanged or {:changed, query} so callers can skip passing unchanged queries to...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8e00140a79053dabfa859ddddc46bacf?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/8e00140a79053dabfa859ddddc46bacf?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"ElixirStatus","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"ElixirStatus","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/22e4640538124187827caf8cc8e39190","url":"https://daily.dev/sources/elixirstatus"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/release-v0-7-0-fuelen-composite-yrw1mbzij","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"elixir,ecto","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"ElixirStatus","item":"https://daily.dev/sources/elixirstatus"},{"@type":"ListItem","position":3,"name":"Release v0.7.0 · fuelen/composite"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/release-v0-7-0-fuelen-composite-yrw1mbzij#faq","mainEntity":[{"@type":"Question","name":"What is the minimum Elixir version required by Composite v0.7.0?","acceptedAnswer":{"@type":"Answer","text":"Composite v0.7.0 requires Elixir ~> 1.14 as its minimum version, up from ~> 1.9 in earlier releases.
