- codeberg.org/gruf/go-bytesize v1.0.3 -> v1.0.4
- codeberg.org/gruf/go-kv/v2 v2.0.6 -> v2.0.7
- codeberg.org/gruf/go-mutexes v1.5.2 -> v1.5.3
- codeberg.org/gruf/go-structr v0.9.7 -> v0.9.8
- codeberg.org/gruf/go-ffmpreg v0.6.8 -> v0.6.9
- github.com/tomnomnom/linkheader HEAD@2018 -> HEAD@2025

all of the above codeberg.org/gruf updates are in preparation for Go1.25, except for bytesize, and also ffmpreg which is a rebuild with the latest version of ffmpeg (v5.1.7)

+# go-mangler
+
+[Documentation](https://pkg.go.dev/codeberg.org/gruf/go-mangler).
+
+To put it simply is a bit of an odd library. It aims to provide incredibly fast, unique string outputs for all default supported input data types during a given runtime instance. See `mangler.String()`for supported types.
+
+It is useful, for example, for use as part of larger abstractions involving hashmaps. That was my particular usecase anyways...
+
+This package does make liberal use of the "unsafe" package.
+
+Benchmarks are below. Please note the more important thing to notice here is the relative difference in benchmark scores, the actual `ns/op`,`B/op`,`allocs/op` accounts for running through ~80 possible test cases, including some not-ideal situations.
+
+The choice of libraries in the benchmark are just a selection of libraries that could be used in a similar manner to this one, i.e. serializing in some manner.
