<tbody>
<tr>
<td><strong>Type Checking</strong></td>
<td>- You can now pass generic or overloaded callables to higher-order
functions and Pyrefly will preserve their structure in the return type.
For example, <code>identity(identity)</code> now correctly returns a
generic callable instead of degrading to <code>Unknown</code>. <!-- raw
HTML omitted --><!-- raw HTML omitted -->- Same-scope class rebinds
(like <code>Real = Dummy</code> after <code>class Real</code>) are now
checked against the original class as if it were an implicit
<code>type[Real]</code> annotation, preventing silent type changes and
fixing spurious constructor-call errors. <!-- raw HTML omitted --><!--
raw HTML omitted -->- Generic classes with missing type arguments in lax
mode now default to <code>Any</code> instead of raising variance errors,
improving consistency with how we handle other incomplete types. <!--
raw HTML omitted --><!-- raw HTML omitted -->- Pydantic
<code>field_validator</code> decorators with <code>mode='before'</code>
and <code>mode='plain'</code> are now supported, allowing validators to
accept broader input types before coercion. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- Spurious unpack diagnostics are no longer
emitted when the right-hand side involves <code>Never</code> (e.g.
<code>a, b, c = never()</code> or <code>a, b = (never(), 1)</code>). The
unpack solver is now <code>Never</code>-aware, recognizing that the
producing expression cannot complete and any error message at the unpack
site would be misleading. <!-- raw HTML omitted --><!-- raw HTML omitted
-->- <code>assert</code> statements now check that <code>__bool__</code>
is callable on the test expression, matching the behavior already in
place for <code>if</code>, <code>while</code>, and ternary expressions
(and aligning with mypy and pyright).</td>
</tr>
<tr>
<td><strong>Language Server</strong></td>
<td>- The language server now advertises both <code>source.fixAll</code>
and <code>source.fixAll.pyrefly</code> code action kinds, enabling
selective fix-on-save configuration across editors that implement the
LSP protocol. <!-- raw HTML omitted --><!-- raw HTML omitted -->-
Document highlights now correctly distinguish between read and write
references, setting <code>DocumentHighlightKind::WRITE</code> for
assignments and declarations. <!-- raw HTML omitted --><!-- raw HTML
omitted -->- Go-to-definition on relative imports in site-packages files
now correctly resolves to the package source instead of returning null
when a <code>pyproject.toml</code> exists at the project root. <!-- raw
HTML omitted --><!-- raw HTML omitted -->- Notebook cell index
resolution has been fixed to prevent mismatches between code cells and
markdown cells, eliminating panics and incorrect byte offset
calculations in Jupyter notebooks. <!-- raw HTML omitted --><!-- raw
HTML omitted -->- Cross-module &quot;find references&quot; (external
references) is now enabled by default, returning references across the
entire project rather than just the current file. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- A new quick fix turns the existing
&quot;Did you mean <code>Foo.BAR</code>?&quot; diagnostic note for
missing enum members into a code action that replaces the offending
string literal with the proper enum member access. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- A new <code># pyrefly: ignore</code> quick
fix inserts a suppression comment for the diagnostic at the cursor,
automatically merging into an existing pyrefly-ignore directive on the
same line or on a comment-only line above when present. <!-- raw HTML
omitted --><!-- raw HTML omitted -->- Numeric parameter defaults now
preserve their source spelling (e.g. <code>0o777</code>,
<code>0xFF</code>, <code>0b101</code>) in hover and signature display
rather than being normalized to decimal. <!-- raw HTML omitted --><!--
raw HTML omitted -->- Code actions documentation has been added to the
IDE Supported Features page, covering quick fixes and
<code>source.fixAll.pyrefly</code> configuration.</td>
</tr>
<tr>
<td><strong>Onboarding &amp; VS Code Extension</strong></td>
<td>- A redesigned unconfigured-project experience: when no
<code>pyrefly.toml</code> is found, Pyrefly auto-detects nearby
<code>mypy.ini</code>, <code>pyrightconfig.json</code>, or
<code>[tool.mypy]</code>/<code>[tool.pyright]</code> sections in
<code>pyproject.toml</code> and synthesizes an in-memory configuration
migrated from those settings (using the <code>legacy</code> or
<code>default</code> preset respectively). With no detectable
configuration, the new <code>basic</code> preset is used. <!-- raw HTML
omitted --><!-- raw HTML omitted -->- A new
<code>python.pyrefly.typeCheckingMode</code> workspace setting (auto /
off / basic / legacy / default / strict, default <code>auto</code>) lets
users pick a preset for files not covered by an explicit Pyrefly
configuration, directly from the VS Code settings UI. The legacy
<code>python.pyrefly.displayTypeErrors</code> setting is now deprecated,
with values transparently mapped to the new model. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- A new
<code>python.pyrefly.disableTypeErrors</code> workspace setting provides
a clean per-workspace kill switch for diagnostics, independent of the
type-checking mode. <!-- raw HTML omitted --><!-- raw HTML omitted -->-
The VS Code status bar has been redesigned: it now shows the active
preset (e.g. &quot;Pyrefly (Legacy)&quot;, &quot;Pyrefly (Basic)&quot;)
and the tooltip explains why that preset was chosen and links to the
relevant docs. <!-- raw HTML omitted --><!-- raw HTML omitted -->- After
a <code>pyrefly check</code> on an unconfigured project, the CLI now
prints a short upsell to <strong>stderr</strong> explaining what
configuration was synthesized and pointing at <code>pyrefly init</code>.
The message is routed to stderr so machine-readable stdout formats (e.g.
<code>--output-format json</code>) remain untouched.</td>
</tr>
<tr>
<td><strong>Configuration</strong></td>
<td>- Configuration presets (<code>off</code>, <code>basic</code>,
<code>legacy</code>, <code>default</code>, <code>strict</code>) are now
available via the <code>preset</code> option, providing named
collections of error severities and behavior settings as a base
configuration that user settings can override. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- The <code>legacy</code> preset is now used
by <code>pyrefly init</code> for mypy migration, disabling checks mypy
doesn't have and setting looser inference defaults. <!-- raw HTML
omitted --><!-- raw HTML omitted -->- The <code>implicit-any</code>
error code has been split into sub-kinds
(<code>implicit-any-attribute</code>,
<code>implicit-any-empty-container</code>,
<code>implicit-any-parameter</code>,
<code>implicit-any-type-argument</code>) with <code>implicit-any</code>
as the parent, allowing finer-grained control over where implicit
<code>Any</code> is flagged. <!-- raw HTML omitted --><!-- raw HTML
omitted -->- The <code>unbound-name</code> error is now disabled in the
<code>legacy</code> preset to match mypy's default behavior, which does
not flag possibly-undefined variables.</td>
</tr>
<tr>
<td><strong>Error Reporting</strong></td>
<td>- A new <code>incompatible-overload-residual</code> error kind has
been introduced for cases where all branches of an overloaded callable
are pruned during higher-order function analysis, making it easier to
configure these errors independently. <!-- raw HTML omitted --><!-- raw
HTML omitted -->- Error messages for all-pruned overload residuals now
describe the incompatibility in terms of &quot;solved type
variables&quot; rather than &quot;solved type constraints&quot; for
better clarity. <!-- raw HTML omitted --><!-- raw HTML omitted -->- The
<code>pyrefly suppress</code> command now correctly handles removal of
unused ignores via the <code>--remove-unused</code> flag, which was
previously broken.</td>
</tr>
<tr>
<td><strong>Factory Boy Support</strong></td>
<td>- Pyrefly now infers the correct model return types for
<code>create()</code>, <code>build()</code>,
<code>create_batch()</code>, and <code>build_batch()</code> methods on
<code>DjangoModelFactory</code> subclasses by reading the inner
<code>Meta.model</code> attribute. <!-- raw HTML omitted --><!-- raw
HTML omitted -->- False-positive <code>bad-override</code> errors on the
inner <code>Meta</code> class in factory-boy factories are now
suppressed, matching how we handle Django and Marshmallow.</td>
</tr>
<tr>
<td><strong>Reporting</strong></td>
<td>- The <code>pyrefly report</code> JSON output now includes a
<code>path</code> field on each <code>ModuleReport</code>, for
compatibility with typestats and similar tooling.</td>
</tr>
<tr>
<td><strong>Performance</strong></td>
<td>- Deeply-nested dict literals no longer cause exponential memory
growth during type inference. A depth-25 dict literal that previously
consumed ~7.7 GB now uses ~239 MB by computing the union of field types
on demand instead of storing it redundantly. <!-- raw HTML omitted
--><!-- raw HTML omitted -->- Callable residual finalization has been
optimized to avoid redundant type cloning and traversals, reducing
memory churn in attribute-heavy code. <!-- raw HTML omitted --><!-- raw
HTML omitted -->- Eliminated some bugs that caused Pyrefly to
unnecessarily analyze dependencies, improving latency and memory use,
especially in the IDE.</td>

<h2>🐛 bug fixes</h2>
<p>We closed <strong>15</strong> bug issues this release 👏</p>
<ul>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3057">#3057</a>:
Fixed an issue where string concatenation with the <code>+</code>
operator was incorrectly flagging <code>str</code> as not assignable to
<code>LiteralString</code> attributes. Pyrefly now preserves
<code>LiteralString</code> style when adding two explicit string
literals and uses implicit style otherwise.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/105">#105</a>:
Fixed premature type pinning in function calls where arguments were
incorrectly narrowed before all constraints were solved. For example,
<code>foo(x, y)</code> with <code>x: int | None</code> and <code>y: int
| None</code> no longer incorrectly narrows <code>x</code> to
<code>None</code> when passed to a generic
<code>foo[T](https://github.com/facebook/pyrefly/blob/HEAD/a: T, b:
T)</code>.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3198">#3198</a>:
Fixed <code>pyrefly suppress --remove-unused</code> which was not
actually removing unused error suppressions. The command now correctly
processes the <code>--remove-unused</code> flag.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3024">#3024</a>:
The language server now advertises <code>source.fixAll.pyrefly</code> in
addition to <code>source.fixAll</code>, allowing users to selectively
enable or disable Pyrefly's fix-all actions in editors that support LSP
code action kinds.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/2819">#2819</a>:
Fixed incorrect variance errors when using generic classes like
Pydantic's <code>RootModel</code> in lax mode. Missing type arguments
now degrade to <code>Any</code> instead of raising errors, matching our
handling of other incomplete types.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3000">#3000</a>:
Fixed &quot;find references&quot; failures in Cursor and other editors
caused by relative imports in site-packages not resolving correctly when
a <code>pyproject.toml</code> existed at the project root.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/2563">#2563</a>:
Fixed go-to-definition on relative imports in virtual environment
site-packages, which was returning null because the project root's
import path was matching before the more specific site-package
prefix.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3193">#3193</a>:
Fixed an error where <code>list[&quot;A|B&quot;]</code> was incorrectly
rejected as <code>not-a-type</code>. Type argument subscripts are now
bound as type expressions even in value context, allowing forward-ref
strings to be parsed.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3286">#3286</a>:
Fixed exponential memory blowup when type-checking deeply-nested dict
literals, which could cause VSCode to be killed by the OS. Memory usage
for a depth-25 dict dropped from ~7.7 GB to ~239 MB.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3261">#3261</a>:
Fixed a false positive <code>bad-class-definition</code> when a
dataclass field was assigned inside a <code>@classmethod</code> or
<code>__init_subclass__</code>. Pyrefly was incorrectly extracting these
as dataclass fields, even though Python's
<code>dataclasses.dataclass</code> ignores them at runtime.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/2914">#2914</a>:
<code>assert</code> statements now flag a non-callable
<code>__bool__</code> on the test expression, closing a gap that
previously only caught the issue inside <code>if</code>,
<code>while</code>, and ternary expressions.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/2867">#2867</a>:
Fixed <code>urlunparse</code> being inferred as returning
<code>Literal[b'']</code> instead of <code>str</code>. The fix reworks
<code>as_superclass</code> so tuple-like <code>NamedTuple</code>
subclasses are upcast through their erased tuple element types, which
stops <code>ParseResult</code> from spuriously matching
<code>Iterable[None]</code> and selecting the bytes overload.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3266">#3266</a>:
Added a quick fix for the existing &quot;Did you mean
<code>Foo.BAR</code>?&quot; diagnostic note for missing enum members,
turning the suggestion into a code action that rewrites the surrounding
string literal.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3230">#3230</a>:
Numeric parameter defaults now preserve their original spelling (e.g.
<code>0o777</code>) in hover and signature display rather than being
normalized to a decimal value.</li>
<li><a
href="https://redirect.github.com/facebook/pyrefly/issues/3302">#3302</a>:
Added a <code>path</code> field to the <code>pyrefly report</code> JSON
<code>ModuleReport</code>, restoring compatibility with typestats.</li>
</ul>

Tournament system meant to be easy to use. Bracket is written in async Python (with FastAPI) and Vite as frontend using the Mantine library.

It has the following features:

Supports single elimination, round-robin and swiss formats.
Build your tournament structure with multiple stages that can have multiple groups/brackets in them.
Drag-and-drop matches to different courts or reschedule them to another start time.
Various dashboard pages are available that can be presented to the public, customized with a logo.
Create/update teams, and add players to teams.
Create multiple clubs, with multiple tournaments per club.
Swiss tournaments can be handled dynamically, with automatic scheduling of matches.

Explore the Bracket docs ▶

Live Demo

A demo is available for free at https://www.bracketapp.nl/demo. The demo lasts for 30 minutes, after which your data will de deleted.

Quickstart

To quickly run bracket to see how it works, clone it and run docker compose up:

git clone git@github.com:evroon/bracket.git
cd bracket
sudo docker compose up -d

This will start the backend and frontend of Bracket, as well as a postgres instance. You should now be able to view bracket at http://localhost:3000. You can log in with the following credentials:

Username: test@example.org
Password: aeGhoe1ahng2Aezai0Dei6Aih6dieHoo.

To insert dummy rows into the database, run:

docker exec bracket-backend uv run --no-dev ./cli.py create-dev-db

Usage

Read the usage guide for how to organize a tournament in Bracket from start to finish.

Configuration

Read the configuration docs for how to configure Bracket.

Bracket's backend is configured using .env files (prod.env for production, dev.env for development etc.). But you can also configure Bracket using environment variables directly, for example by specifying them in the docker-compose.yml.

The frontend doesn't can be configured by environment variables as well, as well as .env files using Vite's way of loading environment variables.

Running Bracket in production

Read the deployment docs for how to deploy Bracket and run it in production.

Bracket can be run in Docker or by itself (using uv and pnpm).

Development setup

Read the development docs for how to run Bracket for development.

Prerequisites are pnpm, postgresql and uv to run the frontend, database and backend.

Translations

Based on your browser settings, your language should be automatically detected and loaded. For now, there's no manual way of choosing a different language.

Supported Languages

To add/refine translations, Crowdin is used. See the docs for more information.
