Fail2Ban vs portfoliobacktest
A side-by-side editorial comparison of Fail2Ban and portfoliobacktest — release velocity, themes, recent moves, and the top alternatives to consider.
Fail2Ban vs portfoliobacktest: at a glance
What is Fail2Ban?
Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
What is portfoliobacktest?
Four dormant years end with a test fix, not a feature
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts. After a run of substantive releases through 2021 and early 2022 it went quiet for four years. The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.

Fail2Ban finally ships 1.1.1 after 14 months in beta, with a botched deb package on the way out the door
◆ Current state
Fail2Ban watches log files for authentication failures and bans the offending addresses through the local firewall. It remains a default component of Linux server hardening, and its release cadence has never matched that prominence — six releases in the eight years before this one. The 1.1.1 final has now landed, closing a beta that had sat unfinished since June 2025, and it installs a systemd-managed socket rather than relying solely on the daemon's own startup.
◆ Where it's heading
The pattern is long silences broken by releases that mostly absorb external change — Python 3.12 and 3.13 compatibility in 1.1.0, a Dovecot filter regression in 1.0.2 — with the substance deferred to a ChangeLog the feed does not carry. What is different this time is the contributor list, which runs to a dozen first-time contributors, suggesting the delay was throughput rather than abandonment. The release also had to be re-cut: the first Debian package shipped with wrong paths from a missing systemd-dev build dependency and was pulled and replaced.
◆ Prediction
Given the beta-to-final gap just closed and the volume of first-time contributors merged into it, the useful thing to watch is whether the next release arrives in months rather than years; the entries do not indicate what it would contain.

◆ Current state
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts. After a run of substantive releases through 2021 and early 2022 it went quiet for four years. The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.
◆ Where it's heading
The development work is behind it. The 2019 to 2022 releases built the substance — parallel execution, resampling that works beyond stock data and beyond daily bars, transaction-cost-aware designs through w_current, and a switch from compounded to uncompounded returns in the Sharpe and annualized return calculations. Since then the package has moved only when a dependency forced it, and even then only far enough to keep the tests green.
◆ Prediction
Nothing in the entries suggests planned work; the next release is most likely triggered by another dependency change, on the same four-year-gap pattern.
