cvsconvert can do multiple conversions in a single run.

Now issues a warning when a vendor branch is detected. Leading !\n in .cvsignore files is translated correctly. Leading # characters on .cvsignore lines get escaped. Spaces in .cvsignore files are translated correctly. git fast-export no longer ships branch-tip resets; track this. Two -g options expose more detail in the output graph. Add -w (whole-repo) option to cvsconvert.

Cope with old-style tagging sometimes found in RCS files. Better detection of repo type (CVS vs RCS). Translate CVS’s handling of spaces and leading ! in ignores.

For git fast-export compatibility, don’t emit NL after comment text.

Fix for expansion of $ headers, doing what the manual actually says. Fix for interpretation of the expand keyword. Test machinery is fully TAPified.

Document how to cope with branch cycle errors.

Document what an overrun of the branch depth limit looks like.

A new 'buildprep' script makes installation from source easier.

Incremental mode suppresses generation of default ignores. The -F and -C mode switches are gone; output is now always mode -C.

Keyword expansion default has been changed to match CVS’s The -k option of cvs-fast-export has been removed. Add yet another required warning about time-skew effects.

Improvements and bugfixes in the release machinery.

Change error messages to modern GCC format. cvsconvert accepts an -A option for an authormap. Minor fix to -kv expansion.

cvsconvert now properly escapes branch names in shell commands. cvssync can now sync from a local cvs respository. Fix for a minor bug when reporting fixups on out-of-order commits. Strengthen documentation warnings about unreliability of CVS timestamps.

Deal gracefully with damaged attic files that yield null branch names.

Make cvsreduce do the right (escaping) thing when a filename contains @. In cvsreduce, warn on files that aren’t CVS masters. Avoid losing commits when warning "tip commit older than imputed branch join" seen Warn about optimization bug triggered by -O3, reduce to -O2.

Allow empty branch labels - these have been observed in the wild. Always report both file and line in syntax errors, using gcc style. Documentation polishing. cppcheck cleanup. Minor port fixes to test machinery.

Fix slightly incorrect generation of default .gitignore file. Make cvsreduce work under Python 3, and test for that.

Revert <2014-11-19T18:11:22Z@flower.powernet.co.uk>, optimization was wrong.

Fix a typo in a property name that affects interoperability with reposurgeon.

Savannah changed how you need to interpret pseudo-URLs.

New -c option for when you can’t trust commit-IDs. Port patch for Sun systems.

Avoid a core dump in another pathological case.

Properly handle CVS masters with nonempty access lists. Bail out gracefully on pathological masters with no revisions.

Another Python compatibility fix. Fix inconsistent license header in revdir.c.

Deal with a really annoying build-portability glitch around -lrt. Fix cvsconvert to be Python 2.6-compatible.

Emit a source type declaration reposurgeon can use. Project now has a logo.

Improve OSX portability.

Tagged branchlets created for CVS tags not matching a gitspace commits. Many portability fixes for *BSD.

A significant improvement in the correctness of vendor-branch handling. More speed improvements.

Fix for buggy emission of lines ending in @. More speedups, and dramatic reduction in working-set size.

The bug that produced "unnumbered head" warnings has been fixed.

cvscompare changed to cvsconvert, a validating wrapper script. The rules for keyword expansion have changed yet again.

Simplify and fully document -k; it now requires an argument. In normal (non-promiscuous) mode, paths containing CVSROOT are ignored. There is a new wrapper script, 'cvscompare', for sanity-checking conversions. A HOWTO on reporting bugs has been added to the distribution.

Bugfix release: a late change to I/O buffering in 1.23 was faulty.

New -l option for redirecting logs during long conversions. More speedups and working-set reductions. Incremental dumping can now be done in fast mode.

New --embed-id and --expand options by Robert deBath.

When incremental dumping, suppress tags associated with old commits. Performance improved by x8; see also the new -F and -C options. New -a option to dump a list of author IDs found in a repo.

Files not ending with ,v are now ignored unless the new -P option is on. New -t option for parallelizing analysis on multicore systems.

Dramatic speedups in some bottleneck functions.

A bug in the regression tests was fixed by slowing down calls to CVS.

Some changes to reduce working-set size. More internals documentation.

Added an internals tour to the documentation. Polished some comments. Prevented a possible buffer overrun. Fixed broken -R option.

Fixed a nasty order-instability bug that was confounding testing. Add a fatal error check for when revision numbers in input get too long. A significant speed improvement by tuning one of the sort algorithms.

Fixed several issues near ignore conversions.

Allow []! in symbol names. Python in the test suite now runs under 2.6.

Teach cvssync about sourceware.org.

Prepends CVS default ignores to converted .cvsignores. Generates a .gitignore containing default CVS ignores when necessary.

RCS/CVS usernames may now begin with a digit (patch by Jesse Weinstein). Cleaned up a mess around keyword expansion; it had been misdocumented. Fixed some minor bugs in the test suite. Fixed a signedness issue on 64-bit machines.

Processing of hardlinks field was incorrect, is now fixed.

Allow # in symbol names. Addresses a corner case in the NetBSD repository.

Fix a brown-paper-bag bug in cvssync.

Skip a hardlinks field, if present. Add a -c option to cvssync that makes mirrors with CVSROOTs.

Improved performance on masters with lots of symbols; thank Jens Bethkowsky.

Smarter blob directory creation to reduce search overhead for blobs.

Cope with CVS-NT kopt strings containing garbage binary data.
