Month: 2024-11 Overview: Delivered a set of stability-focused enhancements for the beta development workflow and the beta website Docker environment, complemented by substantial documentation improvements for Phone Numbers and Caller ID. The work reduces onboarding time, improves dev session reliability, and tightens the alignment between documentation and product behavior. Key features delivered: - Beta Development Workflow and Tooling Reliability: Consolidated improvements to the beta workflow, including a robust environment-aware shell for beta-sync, a corrected beta-sync command using bash, and automatic Docker image rebuild prior to startup to ensure fresh dev sessions. Representative work items include: scripts/beta-sync.sh updated to use /usr/bin/env bash; package.json: beta-sync command fix; Makefile: added builder dependency for develop target. (Commits: 4115b72..., feba78a..., 9c662f5...) - Beta Website Docker Infrastructure and Environment: Established and streamlined the beta site Docker setup with leaner images, added Docker assets for beta, default host binding for Docusaurus dev server, and documentation on Docker usage. Representative work items include: docker assets for beta website; simplified docker setup; Makefile default host bind for docusaurus; beta.Dockerfile cleanup; repo docs updates. (Commits: 67976661..., 7ca6e455..., 5127701a..., 5c095296..., 2916cc80...) - Phone Numbers and Caller ID Documentation Improvements: Comprehensive updates standardizing terminology, API references for phone number resources, dynamic caller ID mechanism explanation, E.164 formatting, and expanded usage examples. Representative work items include: callerid: standardizing terminology; phonenumbers: new page; updated dynamic caller ID guidance; formatting fixes and doc rewrites.
