--- date: 2020-01-23 title: "Improved base templates, and faster!" description: "In Hugo 0.63 we have improved the base template lookup logic, and this simplification also made Hugo faster …" categories: ["Releases"] --- **Note:** There is already a [patch release](/news/0.63.1-relnotes/) with some fixes. Hugo `0.63` is, in general, **considerably faster and more memory effective** (see the site-building benchmarks below comparing it to `v0.62`). Not that we are particularly concerned about Hugo's build speed. We leave that to others. But we would hate if it got slower, so we have a comprehensive benchmark suite. And when we needed to simplify the template handling code to solve a concurrency issue, it also became more effective. And as a bonus, we also finally got the [base template lookup order](https://gohugo.io/templates/base/#base-template-lookup-order) that you really, really wanted! ```bash name old time/op new time/op delta SiteNew/Bundle_with_image-16 13.2ms ± 2% 10.7ms ± 0% -19.13% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 13.1ms ± 0% 10.8ms ± 0% -17.50% (p=0.029 n=4+4) SiteNew/Tags_and_categories-16 47.7ms ± 1% 43.7ms ± 2% -8.43% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 52.3ms ± 6% 49.5ms ± 7% ~ (p=0.200 n=4+4) SiteNew/Deep_content_tree-16 77.7ms ± 0% 71.6ms ± 1% -7.84% (p=0.029 n=4+4) SiteNew/Many_HTML_templates-16 44.0ms ± 2% 37.5ms ± 1% -14.79% (p=0.029 n=4+4) SiteNew/Page_collections-16 58.4ms ± 1% 52.5ms ± 1% -10.09% (p=0.029 n=4+4) name old alloc/op new alloc/op delta SiteNew/Bundle_with_image-16 3.81MB ± 0% 2.22MB ± 0% -41.57% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 3.60MB ± 0% 2.01MB ± 0% -44.09% (p=0.029 n=4+4) SiteNew/Tags_and_categories-16 19.3MB ± 1% 14.2MB ± 0% -26.52% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 70.7MB ± 0% 69.0MB ± 0% -2.30% (p=0.029 n=4+4) SiteNew/Deep_content_tree-16 37.0MB ± 0% 31.2MB ± 0% -15.78% (p=0.029 n=4+4) SiteNew/Many_HTML_templates-16 17.5MB ± 0% 10.6MB ± 0% -39.68% (p=0.029 n=4+4) SiteNew/Page_collections-16 25.8MB ± 0% 21.2MB ± 0% -17.80% (p=0.029 n=4+4) name old allocs/op new allocs/op delta SiteNew/Bundle_with_image-16 52.3k ± 0% 26.1k ± 0% -50.08% (p=0.029 n=4+4) SiteNew/Bundle_with_JSON_file-16 52.3k ± 0% 26.1k ± 0% -50.06% (p=0.029 n=4+4) SiteNew/Tags_and_categories-16 337k ± 1% 272k ± 0% -19.20% (p=0.029 n=4+4) SiteNew/Canonify_URLs-16 422k ± 0% 395k ± 0% -6.33% (p=0.029 n=4+4) SiteNew/Deep_content_tree-16 400k ± 0% 314k ± 0% -21.41% (p=0.029 n=4+4) SiteNew/Many_HTML_templates-16 247k ± 0% 143k ± 0% -41.84% (p=0.029 n=4+4) SiteNew/Page_collections-16 282k ± 0% 207k ± 0% -26.31% (p=0.029 n=4+4) ``` This release represents **35 contributions by 9 contributors** to the main Hugo code base. [@bep](https://github.com/bep) leads the Hugo development with a significant amount of contributions, but also a big shoutout to [@hcwong](https://github.com/hcwong), [@flother](https://github.com/flother), and [@RemcodM](https://github.com/RemcodM) for their ongoing contributions. And a big thanks to [@digitalcraftsman](https://github.com/digitalcraftsman) and [@onedrawingperday](https://github.com/onedrawingperday) for their relentless work on keeping the themes site in pristine condition and to [@davidsneighbour](https://github.com/davidsneighbour) and [@kaushalmodi](https://github.com/kaushalmodi) for all the great work on the documentation site. Many have also been busy writing and fixing the documentation in [hugoDocs](https://github.com/gohugoio/hugoDocs), which has received **13 contributions by 10 contributors**. A special thanks to [@bep](https://github.com/bep), [@jeffscottlevine](https://github.com/jeffscottlevine), [@davidsneighbour](https://github.com/davidsneighbour), and [@nicfits](https://github.com/nicfits) for their work on the documentation site. Hugo now has: * 41091+ [stars](https://github.com/gohugoio/hugo/stargazers) * 440+ [contributors](https://github.com/gohugoio/hugo/graphs/contributors) * 286+ [themes](http://themes.gohugo.io/) ## Notes * `.Type` on-page now returns an empty string if not set in the front matter or if `.Section` returns empty. See [#6760](https://github.com/gohugoio/hugo/issues/6760). * Baseof template (e.g. `baseof.html`) lookup order is completely revised/expanded. See [base template lookup order](https://gohugo.io/templates/base/#base-template-lookup-order). We now do template resolution at execution time following the same rules as the template it applies to (e.g. `_default/single.html`). This is an obvious improvement and your site should work as before. * Shortcode params now supports params with raw string literals (strings surrounded with \`\`) that supports newlines. * Note: In a base template (e.g. `baseof.html`), the first template block must be a `define`. ## Enhancements ### Templates * Rework template management to get rid of concurrency issues [c6d650c8](https://github.com/gohugoio/hugo/commit/c6d650c8c8b22fdc7ddedc1e42a3ca698e1390d6) [@bep](https://github.com/bep) [#6716](https://github.com/gohugoio/hugo/issues/6716)[#6760](https://github.com/gohugoio/hugo/issues/6760)[#6768](https://github.com/gohugoio/hugo/issues/6768)[#6778](https://github.com/gohugoio/hugo/issues/6778) * Put Go's internal template funcs in Hugo's map [1cf23541](https://github.com/gohugoio/hugo/commit/1cf235412f98b42aefe368e99a0e9e95bae6eef7) [@bep](https://github.com/bep) [#6717](https://github.com/gohugoio/hugo/issues/6717) ### Output * Add base template lookup variant to docs.json [cafb1d53](https://github.com/gohugoio/hugo/commit/cafb1d53c0927e2aef8abff1bf9095c90c6f3067) [@bep](https://github.com/bep) ### Core * Disable a test assertion on ARM [836c2426](https://github.com/gohugoio/hugo/commit/836c24261f9f175254256fb326d92a3db47e1c75) [@bep](https://github.com/bep) [#6655](https://github.com/gohugoio/hugo/issues/6655) * Some more benchmark adjustments [ddd75f21](https://github.com/gohugoio/hugo/commit/ddd75f212110a3d6643a07301e377415f3d163bd) [@bep](https://github.com/bep) * Adjust site benchmarks [4ed6ebef](https://github.com/gohugoio/hugo/commit/4ed6ebef4ca71572a19bb890cb4c026a688b2b5b) [@bep](https://github.com/bep) * Add a benchmark with lots of templates [ea05c0e8](https://github.com/gohugoio/hugo/commit/ea05c0e8456e8dec71ffd796148355b0d8b36eb0) [@bep](https://github.com/bep) ### Other * Regen docs helper [4f466db6](https://github.com/gohugoio/hugo/commit/4f466db666dded1b6c6d1e6926e170f22164433a) [@bep](https://github.com/bep) * Allow multiple arguments in ne/ge/gt/le/lt functions Treat op arg1 arg2 arg3 ... as (arg1 op arg2) && (arg1 op arg3) and so on for ne/ge/gt/le/lt.
