# Changelog What each version of pperl changed, one page per version, newest first. A version is the time the version number was in force: it begins when pperl is set to that number and ends when it is set to the next one. The newest page is the version in development; its changes are added as they are made. Every page accounts for all the work of its version: each change is either described in an entry or was internal (tests, benchmarks, build machinery) with no observable effect. An entry opens with its subject in bold, so a page can be scanned for a module or a feature by name. Version numbers that have no page, such as 0.6.4, 0.6.7 and 0.6.10, were never set; their changes are in the version before them. ```{toctree} :maxdepth: 1 0.6.23 0.6.22 0.6.21 0.6.20 0.6.19 0.6.18 0.6.17 0.6.16 0.6.15 0.6.14 0.6.13 0.6.12 0.6.11 0.6.9 0.6.8 0.6.6 0.6.5 0.6.3 0.6.2 0.6.1 0.6.0 0.5.6 ```
